Abstract
Exercise-based interventions are a common management strategy in patients with thumb carpometacarpal joint osteoarthritis (CMCJ OA); however, their exact effect on or the use of an optimal training programme for reducing pain and disability remains unclear. Our purpose was to evaluate the effectiveness of exercise-based interventions compared with other conservative interventions in patients with CMCJ OA. We performed a systematic review and meta-analysis based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Fourteen randomised clinical trials with 1280 patients were finally included. Exercise-based interventions present statistically and clinically better outcomes in reducing pain intensity (mean difference [MD]: -21.91; 95% confidence interval [CI]: -36.59, -7.24; p = 0.003) and wrist disability (MD: -8.1, 95% CI: -4.6, -11.5; p = 0.02) compared with no treatment at short-term follow-up. Proprioceptive exercises have statistically and clinically better outcomes compared with standard care only in pain intensity at very short-term (standardised mean difference [SMD]: -0.76; 95% CI: -1.30, -0.21; p = 0.007) and short-term (SMD: -0.93; 95% CI: -1.86, -0.01; p = 0.049) follow-up and statistically better results in wrist disability at very short-term (SMD: -0.94; 95% CI: -1.68, -0.21; p = 0.01) follow-up. No differences were found between the comparators at mid- and long-term follow-up. Low to moderate certainty of evidence suggests that exercise-based interventions can provide clinically better outcomes compared with no treatment in patients with thumb CMCJ OA, at least in the short term.

Abstract
Background: Telerehabilitation to guide self-management has been shown to be a feasible care strategy for knee osteoarthritis (KOA). The aim of this study was to explore the effectiveness of a blended web-based rehabilitation program enhanced with outdoor physical activity (BWR-OPA) and consultation versus an OPA (usual care) program in KOA patients. Methods: Forty-four KOA participants were prescribed to follow the programs five times/week for 6 weeks. The primary outcome was self-reported physical function, measured by the Knee Injury and Osteoarthritis Outcome Score (KOOS). The secondary outcomes were pain, PA, function (timed up-and-go (TUG) test, 30 s chair rise test (30 s CRT)), psychological functioning and QoL. Results: There was a significant difference between the groups' KOOSs for pain and symptom subscales at the 6- and 12-week post-intervention assessments compared to baseline (p < 0.005) favoring the BWR-OPA group. There was a superior improvement in PA in the BWR-OPA training group (p < 0.05). Statistical and clinical improvements were found (p < 0.001) with effect sizes over 2.0 for objective measures of function. Similar improvements were recorded over time (p < 0.005) at 12 weeks for QoL, KOOS subscales for ADL, QoL and sports/recreation and psychological functioning for both groups. Conclusions: A blended web-based self-managed care program with outdoor PA was superior in many respects to usual care in KOA participants.

Abstract
CONTEXT An easy-to-administer, function-based questionnaire to assess patients with various foot problems was required for a Greek-speaking population. This study aimed to translate and cross-culturally adapt the Quick Foot and Ankle Ability Measure (Quick-FAAM) into Greek and evaluate its reliability and validity. DESIGN Cross-sectional study. METHODS Established international guidelines for the cross-cultural adaptation of questionnaires were followed. The face and content validity of the Greek version of the Quick-FAAM (Quick-FAAM-GR), as well as the internal consistency and test-retest reliability upon repeated administration after 5 days, were examined. In addition, the construct validity of the scale was examined via exploratory factor analysis as well as by testing for associations with the Manchester Foot Pain and Disability Index, the 12-item Short-Form Survey (version 2), and a functional balance assessment test-the Y-Balance Test. RESULTS Sixty participants (18 women) with self-reported chronic ankle instability symptoms, with a median (interquartile range) age of 27 (7.7) years, participated in the study. Half of the participants were included in the test-retest reliability study. The Quick-FAAM-GR demonstrated face and content validity. Excellent internal consistency (Cronbach α = .961) and intrarater test-retest reliability (intraclass correlation coefficient ICC[2,1] = .93) were demonstrated, with a comparable error margin to the original version (standard error of the measurement = 2.1, 95% minimum detectable change = 5.9). Associations of the Quick-FAAM-GR scores to other questionnaires ranged from weak to strong (Spearman rho), all being statistically significant (Manchester Foot Pain and Disability Index from -.26, P = .04, to -.67, P < .001, and 12-item Short-Form Survey, version 2, between .41 and .72, P < .001), and to the Y-Balance Test between lower-limb differences (-.35 to -.58, P < .001). The exploratory factor analysis confirmed the single-factor structure of this scale. No floor/ceiling effects were observed. CONCLUSIONS The Greek Quick-FAAM has proven to be a valid and reliable tool for evaluating chronic ankle instability and can be used for clinical and research purposes in Greek-speaking individuals.

Abstract
Introduction Patients' treatment expectations are key factors influencing the health outcomes in various medical conditions. Using validated measures to capture these expectations has been strongly suggested to improve the prognosis of the health outcome and promote research investigations. The Expectations for Treatment Scale (ETS) is a well-established questionnaire designed to accurately measure treatment expectations in patients with low back pain; however, it is not available in Greek yet. We aimed to translate and cross-culturally adapt the ETS in Greek (ETS-Gr) and evaluate its reliability and validity in a Greek-speaking population with musculoskeletal disorders. Methods We followed published recommendations for the translation and cross-cultural adaptation process of the scale. Face and content validity were evaluated using interviews with patients and experts. Internal consistency, test-retest reliability, and measurement error were evaluated in 52 patients with musculoskeletal conditions. Results During forward and backward translation minor linguistic discrepancies were detected and effectively adapted for Greek-speaking patients. The ETS-Gr presented a high level of content validity (item content validity index: 0.88-1; and average scale content validity index: 0.90), acceptable internal consistency (Cronbach's alpha: 0.84), and excellent test-retest reliability (intraclass correlation coefficient: 0.96, 95% confidence interval: 0.93-0.98). Conclusions The ETS-Gr is a short, reliable, and valid instrument to measure pre-treatment expectations in patients with musculoskeletal disorders. Future investigations including other medical conditions are required.

Abstract
Introduction The Upper Extremity Functional Index (UEFI) is a region-specific questionnaire for patients with upper extremity disorders including patients with rotator cuff-related pain (RCRP). We aimed to translate and cross-culturally adapt the UEFI into Greek (UEFI-Gr) and evaluate its reliability and validity in a Greek-speaking population with RCRP. Methods Published guidelines for translation and cross-cultural adaptation of patient-rated outcome measures were followed. One hundred two patients were asked to complete the Greek versions of the UEFI; Disability of the Arm, Shoulder, and Hand (DASH) questionnaire; and RAND 36-Item Health Survey. Internal consistency, test-retest reliability, measurement error, content validity, concurrent validity, and ceiling and floor effects were evaluated. Results Minor linguistic discrepancies were identified and adopted in the Greek language. The UEFI-Gr presented high internal consistency (Cronbach's alpha: 0.93), excellent test-retest reliability (intraclass correlation coefficient: 0.91; 95% confidence interval {CI}: 0.79-0.95), and acceptable measurement error (standard error of measurement: 4.9 points; minimal detectable change {MDC}: 13.8 points). No ceiling or floor effects were detected. Strong correlations were found with the Greek versions of the Disability of the Arm, Shoulder, and Hand questionnaire (r=0.629; p<0.001) and weak to moderate correlations with most subdomains of RAND 36-Item Health Survey (r=0.30-0.59; p<0.05). Conclusions The UEFI-Gr is a comprehensive, reliable, and valid self-reported instrument to evaluate symptoms in patients with RCRP. Further research on the responsiveness of the questionnaire is necessary.

Abstract
PURPOSE We aimed to translate and cross-culturally adapt the Western Ontario Rotator Cuff index into Greek (WORC-GR) and evaluate its reliability and validity in a Greek speaking population with rotator cuff (RC) disorders. MATERIALS AND METHODS Translation and cross-cultural adaptation process followed published guidelines. Content and face validity were assessed by 9 experts and 16 patients with RC pathologies, respectively. Internal structure, reliability, measurement error, and convergent validity (correlation with the Disability of the Arm, Shoulder and Hand - DASH, Shoulder Pain and Disability Index - SPADI, and Short Form-36) of the index were evaluated in 104 participants (44.2% women, mean age ± SD: 44.9 ± 15.01 years) with RC related pain. RESULTS The WORC-GR showed excellent item and scale content validity index (0.875-1.00 and 0.975, respectively), internal consistency (Cronbach's alpha range 0.749 - 0.903) and test-retest reliability (intraclass correlation coefficient: 0.942, 95% CI: 0.913-0.961). Factorial validity testing revealed a 4-factor structure explaining 69.7% of the total variance. High positive correlations were found with DASH (r = 0.806) and SPADI (r = 0.852). CONCLUSIONS WORC-GR is a reliable and valid instrument to assess symptoms in patients with RC disorders. Further research on the content validity, internal structure, and responsiveness of the tool is required. Implications for rehabilitationThe Greek version of WORC (WORC-GR) is a clear and comprehensible patient reported outcome measure.WORC-GR has excellent internal consistency, test-retest reliability and with no floor and ceiling effects.WORC-GR is a valid outcome measure for patients with rotator cuff disorders.

Abstract
OBJECTIVES To investigate physiotherapists' current knowledge and practice in the management of patients with lateral elbow tendinopathy, to explore associations between the participants' education and management preferences and to identify potential evidence-to-practice gaps by making comparisons with recent research recommendations. DESIGN An on-line cross-sectional survey. SUBJECTS Registered physiotherapists working in Greece with previous experience in the management of lateral elbow tendinopathy. RESULTS Three hundred and seventy eight responses met the inclusion criteria. Most responders (70.4%-91.5%) use pain provocation tests for the diagnosis of the condition, while a limited proportion uses patient rated outcome measures (6.9%-13%). Supervised exercise is the mainstay of rehabilitation (92.6%), followed by adjunctive research recommended treatment techniques such as manual therapy (72%) and advice (59.5%). Up to 83.6% of participants use adjunctive treatment techniques that are not recommended or without research recommendation (such as electrophysical agents, ice etc.). Physiotherapists with post-graduate education in musculoskeletal physiotherapy are almost three times more likely to choose only research recommended treatment approaches. There is a lack of consensus in an optimal exercise programme (type, volume, duration etc.) in patients with lateral elbow tendinopathy. CONCLUSION Despite research recommendations a limited use of patient rated outcome measures in lateral elbow tendinopathy is recorded. Supervised exercise is the first line treatment option for most physiotherapists, although the optimal application is still unclear. A large proportion of physiotherapists apply adjunctive treatment techniques that are either ineffective or poorly researched suggesting a substantial evidence-to-practice gap. Better access to knowledge, organisational and peer-support can potentially help to bridge this gap.

Abstract
INTRODUCTION Sciatica is one of the most common reasons for seeking healthcare for musculoskeletal pain. Sciatica is primarily considered as neuropathic in nature when neural tissue in the low back is compromised, but sometimes other non-neural structures may be involved. Appropriate assessment and management are important for patients with sciatica. Therapists use several outcome measures to assess patients to inform selection of the most suitable treatment. There is limited evidence for the best treatment of sciatica, and this is likely contributed to by having no reliable algorithm to categorise patients based on their clinical characteristics to inform physiotherapy treatment. The purpose of this study is to develop a clinical prediction model to categorise patients with sciatica, in terms of early clinical outcome, based on their initial clinical characteristics. METHODS AND ANALYSIS A prospective observational multicentre design will recruit consecutive patients (n=467) with sciatica referred for physiotherapy. Each patient will be evaluated to determine whether or not they will be accepted into the study by answering some questions that will confirm the study's eligibility criteria. Patients' basic characteristics, patient-reported outcome measures and performance-based measures will be collected at baseline from multiple sites in the Greek territory using this same protocol, prior to commencement of treatment. The main researcher of this study will be responsible for data collection in all sites. On completion of the standard referred physiotherapy treatment after 3 weeks' time, participants will be asked by telephone to evaluate their outcome using the Global Perceived Effect Scale. For the descriptive statistical analysis, the continuous variables will be expressed in the form of 'mean' and 'SD'. In order to assess the prognostic value of each predictor, in terms of the level of improvement or worsening of the symptoms, multiple variable regression analysis will be used. ETHICS AND DISSEMINATION Τhis study is approved from the Ethics and Deontology Committee of the University of West Attica, Athens, Greece, protocol number: 38313-09/06/2020, 10226-10/02/2021. The study's findings will be published in a peer-reviewed journal and disseminated at national and international conferences and through social media. PROSPERO REGISTRATION NUMBER CRD42020168467.

Abstract
BACKGROUND The precise calculation of arterial occlusive pressure is essential to accurately prescribe individualized pressures during blood flow restriction training. Arterial occlusion pressure in the lower limb varies significantly between different body positions while similar reports for the upper limb are lacking. HYPOTHESIS Body position has a significant effect in upper limb arterial occlusive pressure. Using cuffs with manual pump and a handheld Doppler ultrasound can be a reliable method to determine upper limb arterial blood flow restriction. STUDY DESIGN A randomized repeated measures design. LEVEL OF EVIDENCE Level 3. METHODS Forty-two healthy participants (age mean ± SD = 28.1 ± 7.7 years) completed measurements in supine, seated, and standing position by 3 blinded raters. A cuff with a manual pump and a handheld acoustic ultrasound were used. The Wilcoxon signed-rank test with Bonferroni correction was used to analyze differences between body positions. A within-subject coefficient of variation and an intraclass correlation coefficient (ICC) test were used to calculate reproducibility and reliability, respectively. RESULTS A significantly higher upper limb arterial occlusive pressure was found in seated compared with supine position (P < 0.031) and in supine compared with standing position (P < 0.031) in all raters. An ICC of 0.894 (95% CI = 0.824-0.939, P < 0.001) was found in supine, 0.973 (95% CI = 0.955-0.985, P < 0.001) in seated, and 0.984 (95% CI = 0.973-0.991, P < 0.001) in standing position. ICC for test-retest reliability was found 0.90 (95% CI = 0.814-0.946, P < 0.001), 0.873 (95% CI = 0.762-0.93, P < 0.001), and 0.858 (95% CI = 0.737-0.923, P < 0.001) in the supine, seated, and standing position, respectively. CONCLUSION Upper limb arterial occlusive pressure was significantly dependent on body position. The method showed excellent interrater reliability and repeatability between different days. CLINICAL RELEVANCE Prescription of individualized pressures during blood flow restriction training requires measurement of upper limb arterial occlusive pressure in the appropriate position. The use of occlusion cuffs with a manual pump and a handheld Doppler ultrasound showed excellent reliability; however, the increased measurement error compared with the differences in arterial occlusive pressure between certain positions should be carefully considered for the clinical application of the method.

Abstract
OBJECTIVE To evaluate the effectiveness of extracorporeal shockwave therapy compared with other interventions on pain, grip strength and disability in patients with lateral elbow tendinopathy. DATA SOURCES MEDLINE, PubMed, CINAHL, EMBASE, PEDro, ScienceDirect, Cochrane Library and clinical trial registries. REVIEW METHODS We included randomized controlled trials assessing the effectiveness of extracorporeal shockwave therapy alone or as an additive intervention compared with sham or other interventions. Pain intensity, grip strength and elbow disability were used as primary outcome measures. We assessed methodological quality with the PEDro score and quality of evidence with the GRADE approach. RESULTS Twenty-seven studies with 1871 patients were finally included. Extracorporeal shockwave therapy reduced pain intensity at mid-term follow-up (standardized mean difference: -1.21, 95% confidence interval:-1.53, -0.89, P < 0.001) and improved grip strength at very short- (mean difference:3.92, 95% confidence interval: 0.91, 6.94, P = 0.01) and short-term follow-up (mean difference:4.87, 95% confidence interval:2.24, 7.50, P < 0.001) compared with sham treatment. However, no clinically significant results were found between comparators in all outcomes and follow-up times. Extracorporeal shockwave therapy presented clinically better compared to Laser in grip strength at short-term (mean difference:3.50, 95% confidence interval:2.40, 4.60, P < 0.001) and ultrasound in pain intensity at very-short-term follow-up (standardized mean difference: -1.54, 95% confidence interval: -2.60, -0.48, P = 0.005). CONCLUSION Low to moderate certainty of evidence suggests that there are no clinical benefits of extracorporeal shockwave therapy compared to sham interventions or corticosteroid injections. Based on very-low and moderate certainty of evidence, extracorporeal shockwave therapy outperforms against Laser and ultrasound, respectively.Level of Evidence: Therapy, level 1a.

Abstract
BACKGROUND Reviews on the diagnostic performance of the examination tests for lateral elbow tendinopathy (LET) based on updated context-specific tools and guidelines are missing. PURPOSE To review the diagnostic accuracy of examination tests used in LET. DESIGN Systematic review following PRISMA-DTA guidelines. METHODS We searched MEDLINE, PubMed, CINAHL, EMBASE, PEDro, ScienceDirect, and Cochrane Library databases. The QUADAS-2 checklist was used to assess the methodological quality of the eligible studies. We included diagnostic studies reporting the accuracy of physical examination tests or imaging modalities used in patients with LET. RESULTS Twenty-four studies with 1370 participants were identified reporting the diagnostic performance of Ultrasound Imaging (USI) (18 studies), physical examination tests (2 studies) and Magnetic Resonance Imaging (MRI) (4 studies). Most studies (97%) were assessed with "unclear" or "high risk" of bias. Sonoelastography showed the highest sensitivity (75- 100%) and specificity (85- 96%). Grayscale with or without Doppler USI presented poor to excellent values (sensitivity: 53%-100%, specificity: 42%-90%). MRI performed better in the diagnosis of tendon thickening and enthesopathy (sensitivity and specificity: 81%-100%). The Cozen's test reported high sensitivity (91%) while a grip strength difference of 5%-10% between elbow flexion and extension showed high sensitivity (78%-83%) and specificity (80%-90%). CONCLUSIONS Cozen's test and grip strength measurement present high accuracy in the diagnosis of LET but are poorly investigated. USI and MRI provide variable diagnostic accuracy depending on the entities reported and should be recommended with caution when differential diagnosis is necessary. Substantial heterogeneity was found in inclusion criteria, operator/ examiner, mode of application, type of equipment and reference standards across the studies.

Abstract
BACKGROUND Although low back pain (LBP) is a debilitating problem internationally, there is not a lot of research on its impact on physical, psychosocial and lifestyle factors. Especially in mediterranean countries, such as Greece, it is not sufficiently explored whether physical (pain location, activity limitation etc.), sociodemographic (education, smoking etc.) or lifestyle factors (i.e. quality of life or anxiety) are influenced by LBP. OBJECTIVE To estimate LBP prevalence in the Greek general population and explore its association with particular sociodemographic, physical and lifestyle factors. METHOD A sample of 3125 people of the Greek adult population was randomly selected by stratified sampling encompassing rural and urban representation within the Greek mainland. An extended survey form was developed entailing three sections; personal (sociodemographic) information, questions on symptomatology and physical factors (i.e. pain characteristics, recurrence, physical disability etc.) and 3 self-administered questionnaires (including mostly lifestyle factors); Hospital Anxiety and Depression (HAD) scale for anxiety and depression, SF-12 for quality of life (QoL) and Roland-Morris for disability. RESULTS A total of 471 (15%) people reported LBP (210 males, mean age: 47.04 ± 15.03). Amongst them 60% reported sciatica, 76% suffered recurrent LBP and 70% received specialist care. Low disability levels, moderate to high pain intensity, gender differences and good self-reported QoL and psychosocial status were reported. Sociodemographic characteristics (income, smoking, marital status etc.) were not associated with LBP physical factors, apart from age which correlated with physical disability and wellness (r being 0.446 and 0.405, respectively, p< 0.001). Physical factors (particularly pain intensity and location) correlated with lifestyle factors (QoL) and disability (r ranging between 0.396 and 0.543, p< 0.001). Mental wellness, anxiety and depression (as lifestyle factors) were not associated with sociodemographic or physical factors. CONCLUSIONS Physical parameters were amongst the most prevalent characteristics of the Greek sample, thus offering a direction towards a more targeted treatment and rehabilitation planning. Unlike previous literature, most sociodemographic characteristics were not correlated with any LBP physical or lifestyle factors, thus possibly indicating a different socioeconomic background and aetiology domain to that of the usual non-specific LBP spectrum.

Abstract
[Purpose] The appropriate exercise prescription is crucial for achieving scapular stability and providing successful rehabilitation, and the Push-up Plus (PuP) exercise has an important role in shoulder rehabilitation. Consequently, this study examined the effect of support surface stability, hand positioning, and phase of exercise, on the trapezius and serratus anterior muscle contractions as well as on the EMG ratio of the upper/lower trapezius. [Subjects and Methods] Thirteen healthy male volunteers participated in this study. The subjects performed the PuP exercise on stable and unstable supporting surfaces with three different hand orientations. During the PuP exercise, the muscle activities of the upper (UT) and lower (LT) trapezius, as well as the serratus anterior (SA) were measured and expressed as percentages of maximum voluntary isometric contraction (%MVIC). [Results] The EMG activities of UT and LT were statistically greater during the push-up phase compared to the plus phase of the exercise. The contrary was recorded for the activity of the SA. SA was affected by the support surface as well as by the hand positioning. [Conclusion] The results suggest that different phases of the PuP exercise require different muscle stability actions with corresponding activations of appropriate muscle fibers. A detailed prescription of the required phase of the exercise can more effectively activate the scapula-thoracic musculature.

Abstract
OBJECTIVE To identify potential subgroups amongst patients with non-specific low back pain based on a consensus list of potentially discriminatory examination items. DESIGN Exploratory study. PARTICIPANTS A convenience sample of 106 patients with non-specific low back pain (43 males, 63 females, mean age 36 years, standard deviation 15.9 years) and 7 physiotherapists. METHODS Based on 3 focus groups and a two-round Delphi involving 23 health professionals and a random stratified sample of 150 physiotherapists, respectively, a comprehensive examination list comprising the most "discriminatory" items was compiled. Following reliability analysis, the most reliable clinical items were assessed with a sample of patients with non-specific low back pain. K-means cluster analysis was conducted for 2-, 3- and 4-cluster options to explore for meaningful homogenous subgroups. RESULTS The most clinically meaningful cluster was a two-subgroup option, comprising a small group (n = 24) with more severe clinical presentation (i.e. more widespread pain, functional and sleeping problems, other symptoms, increased investigations undertaken, more severe clinical signs, etc.) and a larger less dysfunctional group (n = 80). CONCLUSION A number of potentially discriminatory clinical items were identified by health professionals and sub-classified, based on a sample of patients with non-specific low back pain, into two subgroups. However, further work is needed to validate this classification process.

Abstract
The aim of this study was to evaluate the intra- and inter-examiner reliability and validity of neck range of motion (ROM) measurements. Thirty-five healthy subjects were assessed in all neck movements from two initial positions, sitting and standing, actively (open and closed eyes) and passively by using a 3D ultrasound-based motion analysis device (Zebris). Three tests were employed to assess intra-examiner reliability and two examiners used for the inter-examiner reliability. X-rays in neck flexion and extension were used to validate the Zebris system. The standing position yielded higher intraclass correlation coefficient (ICC) values (>0.86) with less error [smallest detectable difference (SDD)<13.8%] than sitting (ICC>0.79, SDD<14%). Passive assessment of neck ROM presented better reproducibility than active assessment with open or closed eyes in both positions. The inter-examiner reliability was moderate (ICC=0.43-0.68). The correlation between the Zebris system and X-rays was high in both flexion and extension movements. The results showed that the most reliable protocol for assessment of neck ROM is a passive measurement in the standing position. The measurements were well validiated against X-rays and the experience of the investigators must be considered before any comparison among studies is employed.

Abstract
OBJECTIVE: To investigate whether artificial neural networks (ANNs) can categorize healthy subjects, chronic low-back-pain (LBP) patients, and subjects pretending to have low-back pain problems, based upon patterns of stand-sit-stand manoeuvres. DESIGN: A non-invasive laboratory study of human subjects. BACKGROUND: Normal strategies for sit-stand manoeuvres are modified in cases of chronic LBP. Subtle changes and many parameters are unsuitable for conventional statistics. METHODS: Fourteen healthy subjects, 10 chronic LBP patients, and 12 subjects pretending to have LBP participated. Forces and centres of pressure at the feet and knees, plus hip and lumbar movements provided inputs into a three-layer feed-forward ANN with sigmoidal transfer functions. The ANN was trained with data from 35 of the 36 subjects, and its ability to classify the left-out subject was tested. This was repeated with each subject omitted from training in turn. RESULTS: The ANN correctly classified 31 of 36 subjects. The subjects were also classified by nine physiotherapists from videos of the manoeuvres. Their success rate was significantly lower that that of the ANN, which is not surprising for an unusual procedure without training. CONCLUSIONS: ANNs should be considered as additional tools in assessment and possible diagnosis of pathological movements. RELEVANCE: The capacity of ANNs to discriminate patterns of human movement offers a technique that may prove to be a useful tool for assessment and diagnosis.

Abstract
Artificial neural networks and a statistical method, linear discriminant analysis, were both applied to the recognition of temporal gait parameters associated with altered gait patterns. The duration of the double support and right and left single support phases were measured at seven speeds and three walking conditions. Data from 10 subjects were used to train neural networks, which were then tested using data from 10 other subjects. The overall performance of the networks was at least as high as that of linear discriminant analysis. The relative ease with which neural networks can be set up in a computer, and their discriminatory power, suggests that the technique has a useful role to play in gait analysis. RELEVANCE: The capacity of neural networks to recognize alteration of gait patterns suggests that they might provide an alternative approach for gait assessment. They might be proved to be a useful diagnostic tool.
