Description:
[0001]    The present invention relates to a system and method for the biomechanically accurate measurement of posture and for providing a patient with a suitable corrective exercise program. More particularly, the present invention relates to a system and method to automatically analyse the location of anatomical markers placed over skeletal landmarks to obtain biomechanical parameters; a system and method that uses these biomechanical data to automatically detect and/or quantify postural deviations from correct anatomical alignment; a system and method to automatically generate corrective exercise routines. The present invention also relates to the use of the Internet to provide a distributed system for patient care involving image acquisition in a clinical environment, data analysis at a central server and communication between the central server and the health-care professional as well as potential follow-up and feedback between the patient and either the health-care professional or the central server or both.  
         BACKGROUND OF THE INVENTION  
       DESCRIPTION OF PRIOR ART  
         [0002]    A tree trunk grows straight up and tree branches are symmetrical around this solid core to provide a “posture” to withstand the effects of wind and gravity. We too have an optimal posture that allows us to function most efficiently. As builders and architects use plum lines to arrange the walls and supporting structures of a home, we use plumb lines to define this ideal postural alignment. In correct posture, a plumb line dropped from you ear will go through your shoulder, the middle of your pelvis, the middle of your knee, and the front of your anklebone. Your head, trunk, pelvis and knees are “stacked” one on top of the other. Deviations from this positioning can have negative consequences to your health and well being, and correcting postural alignment can make a person look and feel better. Ideal or optimal posture minimizes energy expenditure and muscle work necessary to maintain deviant posture in the face of gravitational forces. As patients become more and more proactive in their choice or health care, they will certainly demand amelioration of their disordered posture. For example, lower back pain has often been attributed to abnormal postural relationships between body segments, and is frequently a cause of patient complaints to family care physicians.  
           [0003]    Typically, practitioners are content with a basic appreciation of a client&#39;s posture. Systematic biomechanical analyses are rarely performed because they are time intensive and require specialized equipment. Instead, only qualitative observations are often made. Specialists, such as Chiropractors and physiotherapists are sometimes trained to make postural assessments, often employing qualitative measures to assess posture and determine corrective measures. Practitioners may refer to these specialists, but again, the procedures are time and labor intensive and consequently, are expensive for the patient, who may or may not have insurance to cover these expenses. Further, qualified medical practitioners, such as family practice physicians, may want to perform such analyses but lack the specialized equipment or training to accurately assess posture based on observations alone. Consequently, a cost effective and highly automatic system is needed to assist practitioners in effective assessment and treatment of postural difficulties.  
           [0004]    In 1998, Tonix Santé introduced a biomechanical computation system based on the manual identification of anatomical markers from analog video images. Clinicians manually identified the location of these markers on images and some biomechanical computations were performed. However, it took a long time to place markers because common scotch tape first had to be applied to patients and then markers affixed to this adhesive. There was also no automatic detection of marker placement, no automatic detection of postural deviations, and no automatic generation of exercise routines to ameliorate postural deviations. The placement of anatomical markers on the body&#39;s surface was not based on any established model of ideal postural alignment. In other automated processes for postural evaluation, the markers are placed on the patient&#39;s loose-fitting clothes, such a method lacks precision, because first, it is difficult to determine the location of appropriate structural landmarks through loose-fitting clothing, and the position of the markers may move because clothing can move in relationship to the skin surface. Also, markers can not be safely placed on the patient&#39;s skin because they are not compliant with hypoallergenic requirements.  
           [0005]    Another deficiency of the actual method to evaluate and correct patient&#39;s posture is the loss of control of the health-care practitioner in the treatment given to his or her patient when he or she refers the patient to a specialist such as chiropractor or physiotherapist. The patient has to take several appointments from several potential specialists. Furthermore, no health-care practitioner or specialist alone can benefit from experience with thousands of patients and be able to correlate biomechanical information from these patients with appropriate treatment and results obtained. There is neither a way to share experience in an efficient way between several health-care practitioners and/or specialists treating this many patients. There is also no way to provide a quantified follow-up of progress.

           [0080]    For the purpose of the present invention the following terms are defined below.  
           [0081]    The term “anterior view” is intended to mean the view of the front of the body (with the person in anatomical position). The term “lateral view” is intended to mean the view of the patient from the side.  
           [0082]    The term “posterior view” is intended to mean the view of the patient from behind.  
           [0083]    The term “body segment parameters” is intended to mean the spatial coordinates of body segments and key anatomical landmarks taken from the images from the lateral, anterior and posterior views.  
           [0084]    The present invention provides a process and apparatus to acquire patient images rapidly and accurately in a clinical environment, to extract body segment parameters from surface markers, a method for analysing these data to obtain biomechanical parameters and deviations, a method involving the use of these biomechanical parameters and deviations for the detection of postural deviations and the selection of corrective exercices, and the use of Internet to provide a distributed system for patient care involving image acquisition in a clinical environment, data analysis at a central server and communication between the central server and the health-care professional as well as potential follow-up and feedback between the patient and either the health-care professional or the central server or both. The placement of markers based on a well established model of ideal postural alignment is crucial because the placement of markers determines the relative deviation of body segments from vertical and horizontal “plumb” or ideal alignment. The current system uses the most widely used and respected anatomical definition of ideal postural alignment (Kendall, McCreary, &amp; Provance, 1993). And, a sophisticated marker placement system has been designed to place surface markers on locations defining this alignment. The importance of a correct definition of ideal posture is obvious when one is attempting to detect postural deviations. A further crucial difference between the earlier systems and the present invention is the use of scanning technology to automatically detect the location of reflective markers placed on the skin overlying skeletal landmarks. They can be placed directly on the skin because they are made from a hypoallergenic material. Such marker placement is highly important, because it avoids the potential examiner error associated with the manual identification of presumed skeletal landmarks from video images. The current system automatically detects markers, and their locations are transmitted automatically through the web for the calculation of postural deviations. Further differences between earlier state of the art and the current system includes the automatic generation of a personalized exercise plan based on individualized and automatic assessments of patients&#39; biomechanical and postural status.  
           [0085]    As such, the biomechanical knowledge system radically changes the practice of biomechanical analysis by creating an objective and effective methodology that is simple to implement using complex yet innovative technology. We have developed a strong theoretical model of biomechanical function as well as innovative methods for data capture, analysis and adapted exercise routines. Both theoretical and technological aspects of our system have been integrated into a coherent and operational system.  
           [0086]    We have successfully linked a biomechanical assessment of potential postural deviations to the underlying muscular components giving rise to these deviations. We go further by suggesting specific muscular training routines to ameliorate the underlying muscular and postural deviations. This unique theoretical and methodological link will be outlined in more detail below.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0104]    In accordance with the present invention, there is provided a system and method using biomechanical analysis to generate a schedule of corrective exercises suitable for a patient&#39;s condition.  
         [0105]    The present invention follows the established biomechanical and clinical principle that resting, standing posture is a composite state made up of the relative position of body segments (e.g., head, trunk, legs) in space and relative to gravity. This is known as static postural alignment. Posture can also be described in terms of muscular balance. Proper posture is the result of symmetrical muscular development and the appropriate interaction of flexor and extensor muscles in a way that suit&#39;s a vertical stance.  
         [0106]    The method described in the present application is based on hypotheses underlying muscular balance, such hypotheses being that:  
         [0107]    All alignment problems yield abnormal tension and constrain the skeleton, joints, ligaments and muscles.  
         [0108]    The study of the relative position of linked body segments reveals muscles that are hyper- or hypo-contracted.  
         [0109]    Alignment and muscular balance are correlated for normal posture.  
         [0110]    Muscular imbalance promotes an increase in the distance of a body segment from correct vertical and horizontal alignment.  
         [0111]    Depending on the deviation, antagonist muscle groups must be strengthened or stretched to achieve correct muscular balance and postural change.  
         [0112]    The inseparable qualities that are alignment and muscular balance are central components of correct body mechanics. A correct vertical stance is the result of a harmonious combination of joint and body segment positions, which in turn stem from an optimal ratio of agonist/antagonist muscles. The energy expenditure required by the muscles is minimal. Therefore, there is an optimal alignment of the body that must take into account all anatomical structures involved in maintaining this alignment. Further, alignment is maximal when the load-bearing structures are also positioned optimally relative to gravity. The sum of forces that act on anatomical structures are balanced if the body is correctly positioned. Daily activities and habits often transform the body from ideal postural alignment independently of disease or structural anomalies. This can have highly negative consequences on daily living, and particularly in terms of the energy necessary to maintain the disordered posture and overlying movements. It is therefore very important to identify and correct these postural deviations.  
         [0113]    The following steps are involved in the postural assessment-postural deviation muscular identification-exercise process. These steps consists of:  
         [0114]    Comprehensive biomechanical analysis  
         [0115]    Identification of postural deviations and ranking by order of priority  
         [0116]    Specification of muscular factors underlying the postural deviations  
         [0117]    Personalised muscular stretching and exercises routines to ameliorate postural deviations that incorporates level of difficulty and order of priority of deviations  
         [0118]    Assessment of client progress by follow-up Biomechanical Assessment Reports and  
         [0119]    Modification of exercise protocol, if necessary.  
         [0120]    The marker construction according to the preferred embodiment is illustrated in FIGS. 4 and 5. There are two types of markers, flat round disks  25  and spheres  30 . The disks  25  and spheres  30  share the same diameter, namely about 2 cm. The spherical and flat markers are placed on the surface of a patient&#39;s body using hypoallergenic adhesive, the markers being placed over skeletal landmarks that define ideal postural alignment. The skeletal landmarks used in the present invention are landmarks which have been recommended by the teachings of Kendall et al. (1993) mentioned above. The adhesive layer  24  is provided on a release sheet  20  with a lift-off tab  24 . The retroreflective disk  25  is already attached to the adhesive sheet  22  which has the same shape as the disk, except for the tab  24 . Due to the double-sided adhesive sheet  22 , the adhesive layer  21  is hypoallergenic and is used to contact the skin or the tight clothing of th patient  36 , while the adhesive layer  23  allows the disk  25  to be held in place or peeled off. When the disk  25  is peeled off, the sheet  22  remains adhered to the patient surface  36 , and exposes the layer  23 . The sphere  30 , having a truncated flat side is adhered to layer  23 , and is thus applied to patient surface  36 . The sphere  30  comprises a wooden core  32  which is dipped in a retroreflective paint (Axon Alert 1460, Axon Aerospace, Greenville, U.S.A.) which forms a coating  34 .  
         [0121]    The disk  25  is cut from stock sheet of retroreflective material made by 3M, namely 3929 Thermal Transfer Printable Retro-Reflective Label Stock and has a thickness of 3 mm. The double-sided adhesive sheet  22  is made by 3M, namely 1522, Double Coated Medical Tape. The adhesive layers  21  and  23  are hypoallergenic, pressure sensitive acrylate adhesive. The coating material  34  comprises 85% solids per weight and the fineness of grind is 200 mesh. The mixing and coating process is as follows. Surfaces to be paint are cleanned and lightly abraded before coating. The spheres are then dipped between 2 to 5 minutes and dryed under normal drying conditions.  
         [0122]    Four digital images are taken of the patient using camera  10  in order to provide a visual image of postural alignment for the patients and health-care professionals and for the automatic detection of body segment parameters. The camera  10  has a standard built-in flash  12  which is set to operate during image acquisition. The intense light form the flash is reflected by the markers  25  and  30  and the markers appear as bright small circles in the acquired images. The high contrast of the markers  25  and  30  with respect to the image of the patient facilitates later automatic recognition of the markers. The placement of markers in the anterior view is shown in FIG. 1. FA02 is a spherical marker placed on the glabella, FA 03  is a spherical marker placed on the middle of the chin and overlying the mental protuberance, FA05 is a spherical marker placed on the right shoulder over the acromion, FA07 is a spherical marker placed on the left shoulder over the acromion, FA 06  is a marker placed on the jugular notch, FA08 is a marker placed over the umbilicus, FA09 is a spherical marker placed on the right anteriosuperior iliac spine, FA11 is a marker placed on the left anterior superior iliac spine, FA 12  is a marker placed on the right wrist over the styloid process of the radium, FA 13  is a marker placed on the left wrest over the styloid process of the radius, FA14 is a marker centered over the right patella, FA15 is a marker centered over the left patella, FA 16  is a marker centered between the right medial and lateral malleoli, FA 18  is a marker centered between the left medial and lateral malleoli, FA19 is a marker placed on the anterior aspect of the right distal phalanx of the great toe and FA20 is a marker placed on the anterior aspect of the left distal phalanx of the great toe.  
         [0123]    The markers on the lateral view are placed as shown in FIG. 2. SD01 is a marker placed on the tragus of the right ear, SD 02  is a spherical marker placed on the glabella, SD 03  is a spherical marker placed on the middle of the chin, and overlying the mental protuberance, SD04 is a spherical marker placed on the right shoulder over the acromion, SD 05  is a spherical marker placed over the right posterior superior iliac spine, SD 08  is a spherical marker placed on the right anteriosuperior iliac spine, SD09 is a marker placed over the greater trochanter, SD10 is a marker placed on Gerdy&#39;s tubercle and SD11 is a marker placed on the transverse tarsal joint.  
         [0124]    The markers on the posterior view are placed as shown in FIG. 3. FP03 is a marker placed over the spinous process of the seventh cervical vertebra, FP04 is a spherical marker placed on the left shoulder over the acromion, FP05 is a spherical marker placed on the right shoulder over the acromion, FP06 is a marker placed over the spinous process of the fifth thoracic vertebra, FP07 is a marker placed over the left posterior superior iliac spine, FP08 is a spherical marker placed over the right posterior superior iliac spine, FP 10  is a marker placed on the left wrist over the styloid process of the ulna, FP 11  is a marker placed on the right wrist over the styloid process of the ulna, FP12 is a marker placed over the center of the left popliteal cavity, FP13 is a marker placed over the center of the right popliteal cavity, FP14 is a marker centered over the left Achilles tendon at the level of the medial malleolus, FP16 is a marker centered over the right Achilles tendon at the level of the medial malleolus, FP17 is a marker centered over the calcaneous of the left foot and FP19 is a marker centered over the calcaneous of the right foot.  
         [0125]    Precise position of the markers is essential for accurate biomechanical assessment and detection of postural deviations. For this, the patient must wear very tight workout clothes to avoid hiding the few landmarks that are potentially covered by clothing. Most markers are placed directly over the body surface. The health-care practitioner must palpate the patient to make sure that the markers are well positionned.  
         [0126]    Shown in FIG. 6 is the position of the camera and calibration backdrop. Pictures are taken with a flash to use the retroreflective property of the markers and make them more apparent on the pictures. The first picture is taken from the lateral view with arms down. The second picture is also from the lateral view but with the proximal arm flexed at 90° to detect the position of markers potentially hidden with the arm down. These values are eventually transferred to the more “natural” lateral image with the arm down. The third and fourth pictures are taken from the anterior and posterior views, respectively. The pictures are taken against a backdrop including a plurality of scale and orientation reference marker points facilitating body segment parameters calculation. Also the patient is instructed to stand in a relaxed and normal posture. To help the patient to adopt the most natural body posture possible, the patient is asked to walk in place prior to standing still.  
         [0127]    The digital images are stored on a flash memory card within the camera and then transferred to a card reader connected to a computer which in turn, is connected to the Internet. The health-care professional can then connect to the central processing server ( 4 ) of FIG. 12 entering on the system web site. First step, the health-care practitionner has to identify client. If the client has his or her first evaluation, personal data (height, weight, gender, age, activity level, preferred unit of measurement) is entered. A client identification number is created to identify client data in the database but protect confidentiality. In the second step, the health-care professional starts the image scanning and biomechanical assessment process. The health-care practitioner select each patient&#39;s images in the directory on the computer. The positions of the anatomical markers that define body segments are scanned and coordinates sent via the Internet to the central server for processing. To protect patient privacy, the images themselves are never sent via the Web, only the coordinates of the markers are transferred.  
         [0128]    The digital location of the markers is supplied and the system receives the scan, validates it and sends back a validation message to the health-care practitioner. The health-care professional receives an error message if insufficient or excessive markers are apparent in the automatic scan. A manual function is provided to correct marker placements, if necessary, and the images are re-scanned. If it is determined that the marker position data obtained from the images is flawed, the health-care professional may again acquire the images, possibly after rechecking the marker positioning. As will be appreciated, when the imaging is complete, and after confirming that the marker positions have been validated, the tabs  24  of the adhesive sheets  22  for the markers  25  and  30  facilitate removal of the adhesive sheets from the clothing or skin  36  of the patient (see FIG. 5). Since a large number of markers needs to be removed, saving time in their removal allows the patient to finish up quicker and change back into his or her clothes.  
         [0129]    The next step is to update credit information, submit it to the system and confirm payment. The system sends back a validation message to the health-care practitioner to proceed.  
         [0130]    Further to that step, biomechanical calculations are executed on the central server ( 4 ) of the FIG. 11.  
         [0131]    The first step is the conversion of images from pixels to actual distances. To do so, the origin is redefined as follow:  
         x   ′     =     x   -     w   2                 y   ′     =       h   2     -   y                           
 
         [0132]    where w=image width  
         [0133]    and h=image height  
         [0134]    Then the image rotation is proceed as follow:  
       dx   =       (       C1x   -   C2x     2     )     +     (       C3x   -   C4x     2     )               dy   =       (       C1y   -   C2y     2     )     +     (       C3y   -   C4y     2     )                 x   ″     =         x   ′               y            -       y   ′               x                        y   ″     =         y   ′               y            -       x   ′               x                                    
 
         [0135]    where d={square root}{square root over (d 2 +dy 2 )} 
         [0136]    with C1, C2, C3 and C4 being calibration points from the backdrop.  
         [0137]    With these calculations it is possible to get coordinate values of the position of anatomical markers relevant to plumb lines in millimetres (or inches with conversion). Shown in FIG. 7 is the perspective needed for this process.

         [0141]    The calculation of (1−s/c) is obtained with the following formulas  
         :     tan        (   α   )         =       dy   s     =     y   c

         [0142]    The same calculations may be made with respect to x and the distance d′ can be calculated as:  
         d   ′     =     d        (     1   -     s   c       )                             
 
         [0143]    The calculations made, the coordinates of markers are determined and expressed relative to vertical and horizontal plumb lines. The missing markers positioned in pelvic area are then calculated. Shown below are the equations used to determine marker coordinates and FIG. 12 displays the missing markers on the pelvis area. SD 5 , SD 8 , SV 5  and SV 8  represent the markers on the pelvic area. d is the segment relating SD 5  and SD 8  and b is the segment relating SD 5  and SD 9 . The angle θ is the angle between the markers SD 5  and SD 8 . In reconstructing a right-angle triangle where d is the hypotenuse, w is the leg facing the hypotenuse and h is the remaining leg of the rectangle.

         [0145]    Marker coordinates are used in the next step to determine a patient&#39;s deviations from optimal alignment. Shown in Table 1 are the calculations necessary to determine postural deviations.

         [0146]    Deviations from horizontal and vertical alignment, moments of force and reaction forces, and center of gravity are calculated from the biomechanical parameters obtained from the images in the lateral, anterior and posterior views. The deviation values are referenced with respect to body alignment position values. These values are used both in the detection of postural deviations and also as a follow-up tool to assess patient progress after following a corrective exercise plan.  
         [0147]    These values are used as a diagnostic tool and as a way to measure progress in the patient&#39;s condition.

         [0183]    The center of gravity projection is calculated as follows:  
         [0184]    X coordinates: ((FA17X−(FA02X+FA 04 X)/2)*WeFAH+(FA17X−(FA07X+FA05X)/2)*WeFAS+(FA17X−(FA11X+FA09X)/2)*WeFAP+(FA17X−(FA14X+FA15X)/2)*WeFAK)/(WeFAH+WeFAS+WeFAP+WeFAK)

         [0186]    Where the parameters used to calculate the center of gravity are described herewith:

         [0187]    These coordinates are then compared to the ideal center of gravity position located on the base of support between the feet.  
         [0188]    When the Biomechanical Assessment is complete (a virtual instantaneous process through the central server), data are transferred back to the health-care practitioner&#39;s computer via the Web. A Biomechanical Assessment Report can then be generated and modified as needed. The health-care practitioner has the possibility to adjust postural deviations based on supplemental information that he or she may have noted during the patient&#39;s examination. Postural deviations are ranked automatically and based on the relative importance of the trunk and head and neck stability on postural function. The top three deviations are selected by default for the treatment, but the health-care practitioner has the possibility to select other deviations. Every change made by the health-care practitioner is identidied in the system to take it into account during further statistical analysis. When the deviations selected for the treatment are confirmed correctives exercises are automatically generated. A ten-week exercise schedule is generated which is, again, modifiable by the health-care practitioner if necessary. Exercises are selected compatible with a patient&#39;s activity level from low, to moderately to highly active. The health-care practitioner also has the opportunity to change exercise selection and/or schedule. The health-care practitioner can ask the system to increase or decrease the difficulty level of the program and generate a new schedule based on the request. The health-care practitioner can also remove or add exercises from the program because he or she thinks that a particular exercise can be harmful to the patient or to place emphasis on a particular deviation correction. Finally, health-care practitioner can reorganize the schedule in changing the order of exercises. Presented in Tables 2 and 3 are lists of deviations that are detectable by the current system, as well as the corrective actions by exercising and stretching to correct these deviations.

         [0190]    In a preferred embodiment of the present invention, the system generates a complete list of deviations for the client, in order of corrective priority. Priority is given to those deviations of body segments that are most perturbing to overall postural stability. Severity is also included in the decision making process, and only parameters exceeding critical values from correct vertical or horizontal alignment (of distance or angle) are considered deviations. These critical values were based on consultations with clinicians treating postural disorders and form a preliminary identification of severity. One of the advantages of the current system is that we will have access to large numbers of normative data from which severity rankings can be revised, as necessary. The first three ranked deviations in order of priority are automatically included in the design of the client&#39;s exercise and stretching program. The remaining deviations may be manually selected by the health-care professional based on his or her clinical experience and familiarity with the patient.  
         [0191]    Table 4 shows the priority factors given to postural deviations.

         [0192]    As stated previously, each deviation is linked to corrective actions and these actions, in turn, are linked to appropriate exercises and stretching routines to treat the deviation. The corrective actions are linked to their deviations by a code that specifies the type of action and exercise required to correct the identified deviation. Every exercise is associated with a level of difficulty from one to three. When beginning a biomechanical assessment, the health-care professional indicates his client&#39;s activity level from one to three (level 1=inactive, level 2=moderately active, level 3=highly active and *=all levels of activity). Only those exercises matching the client&#39;s activity level are selected to treat any particular deviation.  
         [0193]    A client&#39;s exercise schedule is divided into three sessions: the first is of two weeks in duration and the last two are of four weeks duration. When an action group contains numerous exercises, the system always selects only the first three exercises and inserts one into each session. When there is only one exercise applicable, it is included in all three sessions. If there are two exercises applicable, the first is slotted into session 1, and the second one into sessions 2 and 3. There is a maximum of twelve exercises applicable per session. When the system calculates more than twelve exercises applicable per session, the user is requested to delete a deviation. This self-regulating process ensures that the entire 10-week exercise program does not include more than thirty-six exercises, and that not more than 12 are prescribed in one week in order to respect a maximum time budget allowed.  
         [0194]    In one other embodiment of the present invention, an artificial neural network is trained to select exercises based on biomechanical segments points coordinates without passing through all previously shown calculations.  
         [0195]    The patient&#39;s personal information, images, biomechanical assessment, postural deviations, corrective actions and associated exercises and stretches are presented in the Biomechanical Assessment Report that is printed by the practitioner. A page from a sample Biomechanical Assessment Report is presented in FIG. 13. Presented are personal information on the patient ( 1 ), lateral view image of the patient with markers ( 2 ), and biomechanical parameters. Presented in FIG. 14 is a page from the same sample Biomechanical Assessment Report that includes specification of the patient&#39;s postural deviations and the associated exercises and stretching. Presented in FIG. 15 is a page from the Postural Analysis Report that displays the exercise schedule generated in the Biomechanical Assessment process. This figure details the personalized exercise routines for the 10-week treatment period. Finally, presented in FIG. 16 is another page from the Biomechanical Assessment Report illustrating and describing a few of the exercises of the exercise schedule. All of the above information is generated automatically (and modifiable manually) by the system.  
         [0196]    In a preferred embodiment of the present invention, after the patient has completed the exercise routines, he or she can return for a follow-up evaluation. Feedback is given by the health-care pratitionner and new images of the patient are taken in order to reevaluate deviations and priorities. A comparative Biomechanical Assessment Report is generated comparing two assessments. The goal is to assess the effects of treatment and modify the exercise regime, if necessary. A quantified analysis of improvement is therefore provided and both the patient and health-care practitioner can visualize progress towards ideal postural alignment. In another embodiment of the present invention, feedback is provided directly by the patient through the web site, such information being used as a complement in the postural evaluation and in further exercise selection.  
         [0197]    Importantly, all biomechanical data linked to personal information parameters such as height, weight, and age are stored centrally. In one embodiment of the invention, correlation is executed between the personal information parameters, the exercises selected in the Biomechanical Assessment and between the improvement of the patient&#39;s condition. This correlation allows the determination of the exercises which are more efficient for the different elements associated with the patient such as the deviation severity, the age, the gender or the activity level. Parameters used in deviation-exercises correlation are adjusted based on the effectiveness of the exercise program to correct deviations and the exercise program is repeatedly varied until the effectiveness of the exercises is optimized. An important advantage of having calculations performed centrally rather than on locally arranged software, is that improvements and modifications to the system can be made instantaneously across users without delays cause by the more standard transmission of software updates. This is a highly distinguishing aspect of our Biomechanical Assessment system. An additional distinguishing feature is that biomechanical assessments can be peformed at remote locations, as the digital image acquisition can be performed virtually anywhere. Web-based technology is ideally placed to bring cutting-edge health care to potentially disadvantage geographical locations.
