Kinematic and Electromyographic Analysis of the Trunk and Lower Limbs During Walking in Negative-Heeled Shoes
Authors: Li Jing Xian , Hong Youlian 
Published: April 2014

Background: We investigate kinematic adaptation and muscle activities in the trunk and lower extremities of healthy subjects during treadmill walking in negative-heeled sports shoes versus normal sports shoes.
Methods: Thirteen healthy female university students participated in the study. We analyzed sagittal-movement kinematics and electromyographic findings from the erector spinae, rectus abdominus, rectus femoris, biceps femoris, tibialis anterior, and lateral gastrocnemius muscles of the dominant side in two shod conditions.
Results: Negative-heeled gait is characterized by faster cadence, shorter stride length, increased maximal extension angles in the trunk and hip, increased flexion angle in the knee, larger dorsiflexion in the stance phase, and a larger range of motion of the ankle joint. Negative-heeled gait resulted in a significantly larger integrated electromyographic value, a longer duration of electromyographic activity, and a higher mean amplitude of electromyographic activity in the tibialis anterior, lateral gastrocnemius, and biceps femoris muscles.
Conclusions: Negative-heeled gait compared with normal gait places a higher physiologic demand on the tibialis anterior, lateral gastrocnemius, and biceps femoris muscles when walking on a level surface. Thus, negative-heeled shoes could be of value if used in an exercise rehabilitation or training program where inclined walking is not available owing to a flat terrain.

Authors: Frescos Nicoletta , Menz Hylton B. 
Published: April 2014

Background: In Australia, the Department of Veterans’ Affairs provides podiatric medical services, including nail surgery and the provision of footwear and orthoses, for war veterans and their dependents. We sought to evaluate whether the provision of these interventions reduces the number of ongoing maintenance treatments.
Methods: We used the database of the Department of Veterans’ Affairs to document the number of major podiatric medical interventions (footwear, foot orthoses, nail surgery, and combinations of these interventions) for 1996–1997. The number of maintenance podiatric medical treatments provided in the 2 years before (1994–1996) and 2 years after (1997–1999) these interventions was then compared with a control group that did not receive any major interventions.
Results: Compared with the number of treatments in the 2 years before the interventions, in the subsequent 2 years there was a significant increase in the mean ± SD number of maintenance treatments after receiving footwear only (10.4 ± 5.8 versus 12.3 ± 5.0), foot orthoses only (9.4 ± 5.3 versus 12.2 ± 4.6), nail surgery only (10.2 ± 5.8 versus 13.2 ± 4.4), and footwear plus foot orthoses (9.3 ± 6.1 versus 13.3 ± 5.5). In the control group, the mean number of treatments in 1994–1996 and 1997–1999 was 10.8 and 11.8, respectively.
Conclusions: Provision of major podiatric medical interventions did not reduce the number of ongoing maintenance treatments received by veterans. However, owing to the inherent limitations of claims data, it is difficult to determine whether this finding is due to the limited efficacy of the interventions or to the policy structure of podiatric medical service provision in the Department of Veterans’ Affairs.

Authors: Bekler Halil I. , Ertav Aytug 
Published: April 2014

Background: The diabetic foot is one of the main complications of diabetes mellitus, with a high risk of minor or major amputation. The preclinical foot lesions of patients without foot complaints were compared with healthy controls and analyzed.
Methods: This study was conducted with 89 diabetic patients from an endocrinology clinic and 35 nondiabetic control patients. The patients were asked about the presence, types, and durations of pedal complaints; acquired and congenital foot deformities; and atrophy. Patient gaits were inspected for any swelling; skin and nail changes were also recorded. Ranges of articular motion, deformities, crepitations, and any painful perceptions were noted.
Results: The differences between groups were significant for sensorial defects, joint changes of the foot, nail abnormalities, and neuropathic changes.
Conclusions: Every patient with an established diagnosis of diabetes can be considered a potential sufferer of diabetic foot for whom medical therapy and foot protection programs are indicated. (J Am Podiatr Med Assoc 99(2): 114–120, 2009)
Diagnosis and Prevalence of Onychomycosis in Diabetic Neuropathic Patients
Authors: Dumont Isabelle J. 
Published: April 2014

Background: An observational study was conducted to assess the prevalence of onychomycosis in clinically suspected diabetic neuropathic patients and to assess the reliability of the diagnosis.
Methods: One hundred successive type 1 and 2 diabetic patients with diabetic neuropathy were followed. Diabetic neuropathy was defined by a vibration perception threshold greater than 25 V and onychomycosis by clinical diagnosis. Samples of the most affected nail were taken. Potassium hydroxide testing and culture were performed. Photographs of the nails were used by two dermatologists for diagnosis.
Results: The mean ± SE age was 62.3 ± 11.4 years for the 20 onychomycotic patients and 60.3 ± 10.4 years for the entire cohort; 14 onychomycotic patients (70%) were male versus 56 in the full cohort (56%) (P &lt; .05). The prevalence of onychomycosis was 20% (culture and potassium hydroxide test positive) and 24% (culture positive). Twenty or 30 patients were positive by the potassium hydroxide test, depending on the investigator. The most frequent pathogen found was Trichophyton rubrum (11 of 20 patients; 55%). The positive predictive values of the dermatologist’s diagnoses were 57.8% and 35.6%, and the negative predictive values were 85.0% and 90.5%. The two expert’s results were significantly different (P &lt; .05).
Conclusions: The diagnosis of onychomycosis is difficult to make. The diagnostic methods commonly used are not satisfactory. If onychomycosis is dangerous for the diabetic foot, a better diagnostic method is needed. (J Am Podiatr Med Assoc 99(2): 135–139, 2009)
Plantar Pressures During Shod Gait in Diabetic Neuropathic Patients with and without a History of Plantar Ulceration
Authors: Sacco Isabel C. N. , Bacarin Tatiana Almeida , Canettieri Maíra Grizzo , Hennig Ewald M. 
Published: April 2014

Background: Diabetic neuropathy leads to progressive loss of sensation, lower-limb distal muscle atrophy, autonomic impairment, and gait alterations that overload feet. This overload has been associated with plantar ulcers even with consistent daily use of shoes. We sought to investigate and compare the influence of diabetic neuropathy and plantar ulcers in the clinical history of diabetic neuropathic patients on plantar sensitivity, symptoms, and plantar pressure distribution during gait while patients wore their everyday shoes.
Methods: Patients were categorized into three groups: a control group (CG; n = 15), diabetic patients with a history of neuropathic ulceration (DUG; n = 8), and diabetic patients without a history of ulceration (DG; n = 10). Plantar pressure variables were measured by Pedar System shoe insoles in five plantar regions during gait while patients wore their own shoes.
Results: No statistical difference between neuropathic patients with and without a history of plantar ulcers was found in relation to symptoms, tactile sensitivity, and duration of diabetes. Diabetic patients without ulceration presented the lowest pressure–time integral under the heel (72.1 ± 16.1 kPa × sec; P = .0456). Diabetic patients with a history of ulceration presented a higher pressure–time integral at the midfoot compared to patients in the control group (59.6 ± 23.6 kPa × sec × 45.8 ± 10.4 kPa × sec; P = .099), and at the lateral forefoot compared to diabetic patients without ulceration (70.9 ± 17.7 kPa sec × 113.2 ± 61.1 kPa × sec, P = .0193). Diabetic patients with ulceration also presented the lowest weight load under the hallux (0.06 ± 0.02%, P = .0042).
Conclusions: Although presenting a larger midfoot area, diabetic neuropathic patients presented greater pressure–time integrals and relative loads over this region. Diabetic patients with ulceration presented an altered dynamic plantar pressure pattern characterized by overload even when wearing daily shoes. Overload associated with a clinical history of plantar ulcers indicates future appearance of plantar ulcers. (J Am Podiatr Med Assoc 99(4): 285–294, 2009)

Published: April 2014

Background: Research addressing the effect of running shoe type on the low- or high-arched foot during gait is limited. We sought 1) to analyze mean plantar pressure and mean contact area differences between low- and high-arched feet across three test conditions, 2) to determine which regions of the foot (rearfoot, midfoot, and forefoot) contributed to potential differences in mean plantar pressure and mean contact area, and 3) to determine the association between the static arch height index and the dynamic modified arch index.
Methods: Plantar pressure distributions for 75 participants (40 low arched and 35 high arched) were analyzed across three conditions (nonshod, motion control running shoes, and cushioning running shoes) during treadmill walking.
Results: In the motion control and cushioning shoe conditions, mean plantar contact area increased in the midfoot (28% for low arched and 68% for high arched), whereas mean plantar pressure decreased by approximately 30% relative to the nonshod condition. There was moderate to good negative correlation between the arch height index and the modified arch index.
Conclusions: Cushioning and motion control running shoes tend to increase midfoot mean plantar contact area while decreasing mean plantar pressure across the low- or high-arched foot. (J Am Podiatr Med Assoc 99(4): 330–338, 2009)
An Assessment of Strapping Techniques Commonly Used for Pronated Foot Deformities
Authors: Carter Kate , Chockalingam Nachiappan 
Published: April 2014

Background: This study investigated the effects of two low-Dye and two high-Dye strapping techniques that are commonly used to treat pronatory sequelae.
Methods: Plantar pressure distribution in normal adults with a pronated foot type was assessed with a commercially available pressure platform system. Twenty study participants first walked across the platform barefoot and then with each of the four strapping conditions applied. The footprints were averaged and divided into seven areas for analysis.
Results: Paired t tests found significant differences between the barefoot and strapping conditions. Overall, there was a general lateralization of pressures indicating an antipronation effect from all strapping conditions. Low-Dye strap 2, used to limit the degree of calcaneal eversion, produced the most significant changes at the foot pressure areas analyzed.
Conclusions: The data reported in this study suggest that the four strapping techniques offer different levels of control, and this should be considered during the decision-making process and clinical management of pronatory conditions. It was the contention of this study that low-Dye strap 2 was the most effective strapping technique to control foot mechanics associated with a pronated foot type.

Authors: Stratton Michael , McPoil Thomas G. , Cornwall Mark W. , Patrick Kyle 
Published: April 2014

Background: Recent research has discussed the use of low-frequency electrical stimulation to increase blood flow by eliciting muscular contraction in soft tissues. This randomized clinical trial examined the efficacy of low-frequency electrical stimulation combined with stretching exercises and foot orthoses in individuals diagnosed as having plantar fasciitis for less than 6 months.
Methods: Twenty-six participants aged 18 to 65 years diagnosed as having plantar fasciitis were randomly assigned to two treatment groups: a control group receiving only stretching and orthoses and a treatment group receiving low-frequency electrical stimulation in addition to stretching and orthoses. To assess treatment response, a visual analog scale was used to determine first-step morning pain, and changes in daily activity levels were monitored by using a validated outcome measure. All of the participants were assessed before starting treatment, after 4 weeks of treatment, and 3 months after the conclusion of treatment.
Results: Participants in the control and experimental groups demonstrated pain reduction and improvements in functional activity levels after 4 weeks and 3 months.
Conclusions: Regardless of whether low-frequency electrical stimulation was used as an intervention, the use of plantar fascia–specific stretching and prefabricated foot orthoses provided short-term (3-month) pain relief and improvement in functional activity levels.

Published: April 2014

Background: A case-control study was conducted to compare static plantar pressures and distribution of body weight across the two lower limbs, as well as the prevalence of gastrocnemius soleus equinus, in children with and without calcaneal apophysitis (Sever’s disease).
Methods: The participants were 54 boys enrolled in a soccer academy, of which eight were lost to follow-up. Twenty-two boys with unilateral Sever’s disease comprised the Sever’s disease group and 24 healthy boys constituted a control group. Plantar pressure data were collected using pedobarography, and gastrocnemius soleus equinus was assessed.
Results: Peak pressure and percentage of body weight supported were significantly higher in the symptomatic feet of the Sever’s disease group than in the asymptomatic feet of the Sever’s disease group and the control group. Every child in the Sever’s disease group had bilateral gastrocnemius equinus, while nearly all children in the control group had no equinus.
Conclusions: High plantar foot pressures are associated with Sever’s disease, although it is unclear whether they are a predisposing factor or a result of the condition. Gastrocnemius equinus may be a predisposing factor for Sever’s disease. Further research is needed to identify other factors involved in the disease and to better understand the factors that contribute to abnormal distribution of body weight in the lower limbs.

Published: April 2014

Background:Lower-extremity pathologic abnormalities have been common in military recruits for many years. Many of these conditions can become chronic and persist even after retiring from military service. We hypothesized that certain foot abnormalities are more prevalent in veterans versus nonveterans. The purpose of this study was to evaluate what foot and ankle disorders are associated with veteran status while controlling for other demographic factors.Methods:The National Health Interview Survey (Podiatry Supplement) from 1990 was used for this secondary data analysis. The data were divided into veterans and nonveterans, and the prevalence of podiatric medical problems, including callus, flatfoot deformity, bunion deformity, hammer toe deformity, arthritis, and sprain, was evaluated for each group.Results:Flatfoot deformity and arthritis were significantly more prevalent in veterans versus nonveterans in the United States. Bunion deformity was significantly more prevalent in male veterans than in male nonveterans. Male veterans were less likely than male nonveterans to have sprains, and female veterans were more likely than their nonveteran counterparts to have sprains.Conclusions:These results may help us understand the potential risk factors for podiatric medical problems and may be used for formulating prevention programs.

Authors: Mahowald Sarah , Legge Bradford S. , Grady John F. 
Published: April 2014

Background:The purpose of this study was to determine whether changes in plantar fascia thickness are a reliable gauge of efficacy of treatment protocols for plantar fasciitis.Methods:Thirty-nine feet (30 patients) with plantar fasciitis received an ultrasound examination to measure the thickness of the medial band of the plantar fascia. Each patient assessed his or her pain using the visual analogue scale. Following various treatments, a second ultrasound examination was performed and the thickness of the plantar fascia was again measured and subjective pain level assessed.Results:Twenty-nine feet (74.4%) showed a decrease in plantar fascia thickness and a decrease in pain. One foot (2.6%) experienced an increase in fascia thickness and reported an increase in pain. Four feet (10.3%) had an increase in thickness of the plantar fascia and reported no change in pain level. Three feet had minor increases in fascia thickness but reported a decrease in pain (7.7%). One foot (2.6%) had no change in fascia thickness but a decrease in pain and one foot (2.6%) had a decrease in the plantar fascia but no change in pain level. The average reduction in fascia thickness was 0.82 mm ±1.04 mm, correlating with an average improvement in pain of 3.64 ± 2.7 (P &lt; 0.005).Conclusions:This study provides evidence that changing thickness of the plantar fascia is a valid objective measurement to assess effectiveness of new or existing treatment protocols.

The In Vitro Reliability of the CODA MPX30 as the Basis for a Method of Assessing the In Vivo Motion of the Subtalar Joint
Authors: Birch Ivan , Deschamps Kevin 
Published: April 2014

Background:The considerable variation in subtalar joint structure and function shown by studies indicates the importance of developing a noninvasive in vivo technique for assessing subtalar joint movement. This article reports the in vitro testing of the CODA MPX30, an active infrared marker motion analysis system. This work represents the first stage in the development of a noninvasive in vivo method for measuring subtalar joint motion during walking.Methods:The in vitro repeatability of the CODA MPX30 system’s measurements of marker position, simple and intermarker set angles, was tested. Angular orientations of markers representing the position of the talus and the calcaneus were measured using a purpose-designed marker placement model.Results:Marker location measurements were shown to vary by less than 1.0 mm in all of the planes. The measurement of a 90° angle was also found to be repeatable in all of the planes, although measurements made in the yz plane were shown to be consistently inaccurate (mean, 92.47°). Estimation of segmental orientation was found to be repeatable. Estimations of marker set orientations were shown to increase in variability after a coordinate transform was performed (maximum SD, 1.14°).Conclusions:The CODA MPX30 was shown to produce repeatable estimations of marker position. Levels of variation in segmental orientation estimates were shown to increase subsequent to coordinate transforms. The combination of the CODA MPX30 and an appropriate marker placement model offers the basis of an in vivo measurement strategy of subtalar joint movement, an important development in the understanding of the function of the joint during gait.

Interrater and Intrarater Reliability in the Measurement of Ankle Joint Dorsiflexion is Independent of Examiner Experience and Technique Used
Authors: Kim Paul Jeong , Peace Ruth , Mieras Jamie , Thoms Tanya , Freeman Denise , Page Jeffrey 
Published: April 2014

Background:Goniometric measurement is currently being used as a diagnostic and outcomes assessment tool for ankle joint dorsiflexion. Despite its common use, its interrater and intrarater reliability has been questioned.Methods:This is a prospective study examining whether the experience of the examiner or the technique used affects the interrater and intrarater reliability for measuring ankle joint dorsiflexion. Fourteen asymptomatic individuals (8 male and 6 female) with a mean age of 28.2 years (range, 23–52) were enrolled into this study. The years of clinical experience of the five examiners averaged 10.4 years (range, 0–26). Four examiners used a modified Root, Weed and Orien method of measuring ankle joint dorsiflexion. The fifth examiner utilized a nonstandardized technique. A standard goniometer was used for bilateral measurements of ankle joint dorsiflexion with the knee extended and flexed. All five examiners repeated each measurement three times during each of the three sessions, with each session spaced at least 1 week apart.Results:The interclass correlation coefficient reveals a moderate intrarater and poor interrater reliability in ankle joint dorsiflexion measurements using a standard goniometer. More importantly, further analysis indicates that the use of a standardized technique for measurement of ankle joint dorsiflexion or years of clinical experience does not increase the intrarater or interrater reliability.Conclusions:The utility of the goniometric measurement of ankle joint dorsiflexion may be limited.

Authors: Tonbul Murat , Guzelant Aliye Yildirim , Gonen Aysun , Baca Emre , Ozbaydar Mehmet U. 
Published: April 2014

Background:
We sought to determine the changes in the size of the edema observed on MRI scans and its relation to the patient’s pain during activity and pain during rest in bone marrow edema.

Methods:
A total of 26 patients were followed up at 3-month intervals for a period of 1 year. During the follow-ups, magnetic resonance imaging scans of the patients’ ankles were obtained; the scores obtained on the American Orthopaedic Foot and Ankle Society functional rating scale and visual analog scale were determined. The changes in these parameters and the correlation between them were examined.

Results:
The size of the edema as observed on magnetic resonance imaging scans decreased, and the pain during activity and rest decreased. Although there is a correlation between the decrease in the edema size observed on magnetic resonance imaging scans and decrease in the pain during activity, there is no correlation between the decrease in the edema size observed on magnetic resonance imaging scans and the decrease in pain during rest.

Conclusions:
Patients can be informed more precisely, that the pain during rest and activity may not decrease after the third and sixth month, respectively. Magnetic resonance imaging may not alter after the ninth month, so it may not be necessary to be performed again. (J Am Podiatr Med Assoc 101(5): 430–436, 2011)
