Cross-cultural Adaptation and Validation of the VISA-P Questionnaire for German-Speaking Patients With Patellar Tendinopathy
Authors: Lohrer Heinz , Nauck Tanja 
Published: March 2011

Study Design Clinical measurement study. Objectives To cross-culturally adapt and validate the Victorian Institute of Sports Assessment Patellar Tendinopathy Questionnaire (VISA-P) for German-speaking patients. Background Like most questionnaires, the VISA-P was developed for English-speaking patients. There is a need to adapt the scale for German-speaking patients and thereby add to the total body of psychometric evidence relating to this instrument. Methods The VISA-P questionnaire was translated and cross-culturally adapted into German (VISA-P-G) in 6 steps: translation, synthesis, back translation, expert committee review, pretesting, and advisory committee appraisal. The psychometric properties of the VISA-P-G were determined using 23 patients with patellar tendinopathy and 57 active healthy persons (32 sport students and 25 basketball players). Reliability was evaluated by applying the questionnaire twice within a week to all 80 participants. Known group validity was calculated using a 1-way analysis of variance. Additionally, VISA-P-G results were correlated with the Blazina classification system for patellar tendinopathy, using the Spearman rank correlation coefficient. VISA-P-G ratings from the present study groups were further compared with respective data published in the original English, Dutch, and Swedish versions by a 2-sample t test. Internal consistency for the individual items of the questionnaire was determined within the patient group using a Cronbach alpha. Results Test-retest revealed excellent reliability for the patient and the asymptomatic control group (ICC = 0.88 and 0.87, respectively). Internal consistency for the patients was 0.88. Concurrent validity was almost perfect (ρ = -0.81; P<.001). Conclusion The VISA-P-G is a reliable and valid questionnaire for the self-assessment of pain, symptoms, and function in German-speaking patients with patellar tendinopathy. Its psychometric properties are comparable with the original English and international adaptations (Swedish, Dutch, and Italian).

Published: March 2011

Study Design Controlled laboratory study. Objective To assess the activation of 7 shoulder muscles under 2 closed kinetic chain (CKC) tasks for the upper extremity using submaximal isometric effort, thus providing relative quantification of muscular isometric effort for these muscles across the CKC exercises, which may be applied to rehabilitation protocols for individuals with shoulder weakness. Background CKC exercises favor joint congruence, reduce shear load, and promote joint dynamic stability. Additionally, knowledge about glenohumeral and periscapular muscle activity elicited during CKC exercises may help clinicians to design protocols for shoulder rehabilitation. Methods Using surface electromyography, activation level was measured across 7 shoulder muscles in 20 healthy males, during the performance of a submaximal isometric wall press and bench press. Signals were normalized to the maximal voluntary isometric contraction, and, using paired t tests, data were analyzed between the exercises for each muscle. Results Compared to the wall press, the bench press elicited higher activity for most muscles, except for the upper trapezius. Levels of activity were usually low but were above 20% maximal voluntary isometric contraction for the serratus anterior on both tasks, and for the long head triceps brachii on the bench press. Conclusions Both the bench press and wall press, as performed in this study, led to relatively low EMG activation levels for the muscles measured and may be considered for use in the early phases of rehabilitation.

Individuals with Low Back Pain Breathe Differently Than Healthy Individuals During a Lifting Task
Authors: Hagins Marshall , Lamberg Eric M. 
Published: March 2011

Study Design Case control, repeated-measures, experimental laboratory study. Objective To determine if, during a whole-body lifting task, individuals with low back pain (LBP) breathe differently than age-matched controls. Background Breath control may be optimized to provide increased intersegmental control of the lumbar spine through the generation of intra-abdominal pressure. Consequently, impairments in respiratory and trunk muscle coordination during lifting tasks may contribute to the occurrence or maintenance of LBP. Methods Participants without LBP (n = 30) were matched by gender and age with those presenting with chronic mechanical LBP (n = 32) of at least 1 year in duration. Participants completed a total of 8 self-paced lifts of a crate from the floor to a table, with the crate empty during 4 of the lifts and loaded to 25% of the participant's body weight during 4 of the lifts. The amount of volume in the lungs, measured as a percentage of the individual's vital capacity (%VC), was identified at 9 points during the lifting task. A 2 × 2 × 2 × 9 (group by gender by load by time) mixed-model analysis of covariance (ANCOVA), with age as the covariate, was used to identify differences among conditions and groups of %VC used during the lift. Results Individuals with LBP performed the lifting task with more volume in their lungs (48.2 %VC) than healthy peers (40.9 %VC). Age significantly affected %VC used during the lift: with increasing age, participants with LBP increased inspired volume and participants without LBP decreased inspired volume. Conclusions Individuals with LBP performed a lifting task with more inhaled lung volume than individuals without LBP. These findings are consistent with the theoretical link between breath control, intra-abdominal pressure, and lumbar segmental control.

Study Design Experimental laboratory design. Objectives To examine the effect of force and repetition during oscillatory joint mobilizations on the posterior capsule of the glenohumeral joint. Background The optimal external force and frequency to be used during joint mobilization to elongate the posterior capsule of the glenohumeral joint has yet to be identified. Methods Twenty-one posterior capsules were harvested from fresh-frozen shoulders. A cyclic loading test simulating oscillatory posterior joint mobilization on the shoulder specimens was performed with a material testing machine. The specimens were assigned to 3 different loading groups simulating joint mobilization in the toe (5 N), transition (20 N), and beginning of the linear regions (40 N) of the load displacement curve. Displacement of the humeral head at an applied load of 5 N was recorded at the 1st, 100th, 200th, 300th, 400th, 500th, and 600th cycles and at 1 hour after completion of the cyclic loading. Furthermore, stiffness was calculated after the 1st and 600th cycles and 1 hour after testing. Results Humeral head displacement was significantly greater for the 100th to 600th cycle, compared to the 1st cycle, for all 3 loading groups. Significant increases in displacement and stiffness were observed between the 1st cycle and 1 hour after completion of the cyclic tests for both the 20-N and 40-N loading groups. Conclusion While oscillatory joint mobilization to a force of 5 N resulted in temporary elongation of the posterior capsule, mobilization to loads of 20 and 40 N resulted in sustained elongation of the capsule for up to 1 hour. Our findings also suggest that mobilization up to loads that represent the beginning of the linear region of the load displacement curve could be performed without serious damage to the posterior capsule.

Study Design Controlled laboratory study. Objective To evaluate the effect of low−intensity therapeutic ultrasound on the murine calcaneus tendon healing process. Background Therapeutic ultrasound promotes formation and maturation of scar tissue. Methods Calcaneus tendon tenotomy and tenorrhaphy was performed on 28 Wistar rats. After the procedure, the animals were randomly divided into 2 groups. The animals in the experimental group received a 5−minute ultrasound application, once a day, at a frequency of 1 MHz, a spatial average temporal average intensity of 0.1 W/cm2, and a spatial average intensity of 0.52 W/cm2 at a 16−Hz frequency pulse mode (duty cycle, 20%). Data for the injured side were normalized in relation to the data from the contralateral healthy calcaneus tendon (relative values). The animals in the control group received sham treatment. After a 28−day treatment period, the animals were sacrificed and their tendons surgically removed and subjected to mechanical stress testing. The parameters analyzed were cross−sectional area (mm2), ultimate load (N), tensile strength (MPa), and energy absorption (mJ). Results A significant difference between groups was found for the relative values of ultimate load and tensile strength. The mean ± SD ultimate load of the control group was −3.5% ± 32.2% compared to 33.3% ± 26.8% for the experimental group (P = .005). The mean tensile strength of the control group was −47.7% ± 19.5% compared to −28.1% ± 24.1% for the experimental group (P = .019). No significant difference was found in cross-sectional area and energy absorption. Conclusion Low-intensity pulsed ultrasound produced by a conventional therapeutic ultrasound unit can positively influence the calcaneus tendon healing process in rats.

Published: March 2011

Study Design Controlled laboratory study, using a repeated-measures, counterbalanced design. Objectives To provide estimates on the average knee angle maintained, absolute knee angle error, and total repetitions performed during 2 versions of the heel raise test. Background The heel raise test is performed in knee extension (EHRT) to assess gastrocnemius and knee flexion (FHRT) for soleus. However, it has not yet been determined whether select knee angles are maintained or whether total repetitions differ between the clinical versions of the heel raise test. Methods Seventeen healthy males and females performed maximal heel raise repetitions in 0° (EHRT) and 30° (FHRT) of desired knee flexion. The average angle maintained and absolute error at the knee during the 2 versions, and total heel raise repetitions, were measured using motion analysis. Participants' kinematic measures were fitted into a generalized estimation equation model to provide estimates on EHRT and FHRT performance applicable to the general population. Results The model estimates that average angles of 2.2° and 30.7° will be maintained at the knee by the general population during the EHRT and the FHRT, with an absolute angle error of 3.4° and 2.5°, respectively. In both versions, 40 repetitions should be completed. However, the average angles maintained by participants ranged from −6.3° to 21.6° during the EHRT and from 22.0° to 43.0° during the FHRT, with the highest absolute errors in knee position being 25.9° and 33.5°, respectively. Conclusions On average, select knee angles will be maintained by the general population during the select heel raise test versions, but individualized performance is variable and total repetitions do not distinguish between versions. Clinicians should, therefore, interpret select heel raise test outcomes with caution when used to respectively assess and rehabilitate soleus and gastrocnemius function.

Study Design A randomized controlled clinical trial. Objective To investigate the effects of trigger point (TrP) manual therapy combined with a self-stretching program for the management of patients with plantar heel pain. Background Previous studies have reported that stretching of the calf musculature and the plantar fascia are effective management strategies for plantar heel pain. However, it is not known if the inclusion of soft tissue therapy can further improve the outcomes in this population. Methods Sixty patients, 15 men and 45 women (mean ± SD age, 44 ± 10 years) with a clinical diagnosis of plantar heel pain were randomly divided into 2 groups: a self-stretching (Str) group who received a stretching protocol, and a self-stretching and soft tissue TrP manual therapy (Str-ST) group who received TrP manual interventions (TrP pressure release and neuromuscular approach) in addition to the same self-stretching protocol. The primary outcomes were physical function and bodily pain domains of the quality of life SF-36 questionnaire. Additionally, pressure pain thresholds (PPT) were assessed over the affected gastrocnemii and soleus muscles, and over the calcaneus, by an assessor blinded to the treatment allocation. Outcomes of interest were captured at baseline and at a 1-month follow-up (end of treatment period). Mixed-model ANOVAs were used to examine the effects of the interventions on each outcome, with group as the between-subjects variable and time as the within-subjects variable. The primary analysis was the group-by-time interaction. Results The 2 × 2 mixed-model analysis of variance (ANOVA) revealed a significant group-by-time interaction for the main outcomes of the study: physical function (P = .001) and bodily pain (P = .005); patients receiving a combination of self-stretching and TrP tissue intervention experienced a greater improvement in physical function and a greater reduction in pain, as compared to those receiving the self-stretching protocol. The mixed ANOVA also revealed significant group-by-time interactions for changes in PPT over the gastrocnemii and soleus muscles, and the calcaneus (all P<.001). Patients receiving a combination of self-stretching and TrP tissue intervention showed a greater improvement in PPT, as compared to those who received only the self-stretching protocol. Conclusions This study provides evidence that the addition of TrP manual therapies to a self-stretching protocol resulted in superior short-term outcomes as compared to a self-stretching program alone in the treatment of patients with plantar heel pain.

Study Design Case control. Objectives To use modified NFL Combine testing methodology to test for functional deficits in athletes following anterior cruciate ligament (ACL) reconstruction following return to sport. Background There is a need to develop objective, performance-based, on-field assessment methods designed to identify potential lower extremity performance deficits and related impairments in this population. Methods Eighteen patients (mean ± SD age, 16.9 ± 2.1 years; height, 170.0 ± 8.7 cm; body mass, 71.9 ± 21.8 kg) who returned to their sport within a year following ACL reconstruction (95% CI: 7.8 to 11.9 months from surgery) participated (ACLR group). These individuals were asked to bring 1 or 2 teammates to serve as control participants, who were matched for sex, sport, and age (n = 20; mean ± SD age, 16.9 ± 1.1 years; height, 169.7 ± 8.4 cm; body mass, 70.1 ± 20.7 kg). Functional performance was tested using the broad jump, vertical jump, modified long shuttle, modified pro shuttle, modified agility T-test, timed hop, triple hop, single hop, and crossover hop tests. A 1-way multivariate analysis of variance (MANOVA) was used to evaluate group differences for dependent performance variables. Results The functional performance measurements of skills requiring bilateral involvement of both lower extremities showed no group differences between the ACLR and control groups (P:.05). An overall group difference (P = .006) was observed for the combined limb symmetry index (LSI) measures. However, the modified double-limb performance tasks (long shuttle, modified agility T-test, and pro shuttle) were not, independently sufficiently sensitive to detect limb deficits in individuals with ACL reconstruction. Conversely, the LSI on the distance measures of the single-limb performance tasks all provided moderate to large effect sizes to differentiate between the ACLR and control groups, as the individuals who had ACL reconstruction demonstrated involved limb deficits on all measures (P<.05). Finally, the LSI for the timed hop test was not different between groups (P:.05). Conclusions These findings indicate that, while unilateral deficits are present in individuals following ACL reconstruction, they may not be evident during bipedal performance or during modified versions of double-limb performance activities. Isolation of the involved limb with unilateral hopping tasks should be used to identify deficits in performance.

Description, taxinomie, systémique : un modèle pour les emplois des verbes français
Authors: Leeman Danielle 
Published: March 2011

L’objectif est de démontrer la validité et l’actualité des principes épistémologiques fondateurs du structuralisme. Le dictionnaire Les Verbes français , de J. Dubois et F. Dubois-Charlier (2004), est le travail retenu comme exemplaire de cette théorie de l’objet et de la méthodologie qui lui correspond. Il repose en effet sur quatre postulats caractéristiques de la lignée du Cours de Linguistique générale de Ferdinand de Saussure : (1) la nécessaire exhaustivité de la couverture empirique ; (2) la pertinence des propriétés formelles (morphologiques, syntaxiques) et lexicales (distributionnelles) pour un classement sémantique, étant donné l’arbitraire du signe (c’est-à-dire l’autonomie du système linguistique relativement au monde ou à la pensée) et corrélativement l’indissoluble association signifiant-signifié ; (3) la conception de la classification du tout de l’objet comme une théorie, soit une organisation abstraite hypothétique, testable dans ses prédictions et ses explications ; (4) la considération du modèle obtenu comme une construction hypothétique, reflétant les savoirs et choix des savants de l’époque, sans prétention en soi à révéler les lois du fonctionnement du monde ou de celui de la pensée (sinon tel que vu par la langue elle-même).

Published: March 2011

Nous présentons les caractéristiques du Dictionnaire électronique des mots , une base de données qui comporte 140 000 entrées. Chacune d’elles est définie par une dizaine de rubriques qui spécifient, outre son sens, ses propriétés catégorielles, morphologiques, sémantiques, syntaxiques, et cela au moyen d’un codage systématisé. Ces propriétés permettent, en particulier, l’établissement de phrases prototypiques et de classes. Nous examinons trois des rubriques pour illustrer l’idée que la description est une combinatoire d’éléments discrets. À titre d’exemple, nous montrons comment s’organisent la classification et la combinatoire de 1 237 termes (noms, adjectifs, verbes, etc.) concernant le domaine de la musique.
Quand le classement est une théorie : le verbe impersonnel dans Les Verbes français
Authors: Bottineau Didier 
Published: March 2011

Cette étude est consacrée au traitement du verbe et des constructions impersonnelles dans Les Verbes français de J. Dubois et F. Dubois-Charlier (1997). L’objectif est d’expliciter les divers choix ou implications théoriques que sous-tendent les classes et constructions retenues et de montrer comment un objet de description est obtenu en fonction d’une certaine conception préalable du fait à décrire ou à modéliser. On relève diverses particularités : l’absence d’une notation unifiée commune à tous les faits d’impersonnalité ; la présence d’entrées pour les acceptions impersonnelles de certains verbes sélectionnés, mais pas tous ; le changement de classe sémantique, signe que l’impersonnel est considéré comme facteur de grammaticalisation ; et des particularités remarquables concernant les verbes météorologiques. Les implications de ces indices sont formulées à la lumière de diverses approches descriptives et théoriques dont la psychomécanique du langage, l’énonciation, la polyphonie, la théorie des relations interlocutives, et la grammaire cognitive.
Éléments pour un lexique de la complémentation des nominalisations verbales
Authors: Royauté Jean 
Published: March 2011

Les Verbes français (LVF) de J. Dubois et F. Dubois-Charlier (1997) présentent une description fine des verbes du français, de leurs différents emplois et constructions ainsi que différentes contraintes sémantiques sur leurs arguments et circonstants. De plus, pour chacun des emplois de ces verbes, sont fournis les dérivés morphologiques. Sur les 26 130 entrées verbales, nous avons recensé 13 331 nominalisations de ces verbes et nous en avons analysé 463. Nous avons cherché à prédire, en nous aidant du champ « exemple » des phrases de LVF , le GN qui correspond à la nominalisation de ce verbe ainsi que son patron syntaxique. Pour cela, nous avons utilisé les caractéristiques structurelles de ces GN prédicatifs que nous avons mis en évidence et du ou des schèmes syntaxiques correspondant au verbe qui lui est relié. Pour montrer que tous les actants dans la très grande majorité des cas ont une réalisation dans la structure du GN prédicatif, nous présentons ce GN sous une forme saturée, c’est-à-dire avec tous ses arguments.
