Translation into Greek and initial validity and reliability testing of a modified version of the SCIM III,in both English and Greek,for self-use

Purpose: To translate and culturally adapt the Spinal Cord Injury Measure version III (SCIM III) into Greek (GR-SCIM III). To conduct initial testing of psychometric properties of both measures by self-report. Method: Forward–backward translation was conducted to produce the GR-SCIM III. Participants completed the English or Greek versions in 2008–2009. Both versions were examined for multidimensionality, internal consistency and concurrent/criterion validity with the EQ-5D. Results: Forty-five Greek adults with spinal cord injury (SCI) (23 males), mean age 61 (SD17) years; mean time since injury 11 (SD9) years, completed the GR-SCIM III. One hundred and seventy four English-speaking adults with SCI (111 males), mean age 47 (SD12) years; mean time since injury 12 (SD11) years, completed the SCIM III. Unidimensionality was confirmed for both versions. Internal consistency was acceptable (α?=?0.78 for both). Validity was strong for the “self-care” subscale (GR-SCIM III ρ?=??0.78, SCIM III ρ?=??0.75) and moderate for the “mobility” subscale (GR-SCIM III ρ?=??0.58, SCIM III ρ?=??0.45). Conclusions: This has been the first function scale translated and validated in Greek for people with SCI. Both the GR-SCIM III and SCIM III are reliable for use by self-report. More studies are needed to further examine their psychometric properties and compare with observation or interview.

• Implications for Rehabilitation

• The Greek version of the Spinal Cord Independence Measure version III (SCIM) is valid and reliable for self-report. Further testing is needed to assess psychometric qualities not assessed in the present study.

• Researchers and therapists in Greece can use a specific measure to assess functional independence in people with Spinal Cord Injury (SCI).

• Consideration needs to be given to the participants’ type of injury, which may affect the results of SCIM III.

     

Greek cultural adaption and validation of the Kujala anterior knee pain scale in patients with patellofemoral pain syndrome

Purpose: To cross-culturally adapt and validate the Greek version of the Kujala anterior knee pain scale (KAKPS). Methods: The Greek KAKPS was translated from the original English version following standard forward and backward translation procedures. The survey was then conducted in clinical settings by a questionnaire comprising the Greek KAKPS and patellofemoral pain syndrome (PFPS) severity scale. A total of 130 (62 women and 68 men) Greek-reading patients between 18 and 45 years old with anterior knee pain (AKP) for at least four weeks were recruited from physical therapy clinics. To establish test–retest reliability, the patients were asked to complete the KAKPS at initial visit and 2–3 days after the initial visit. The Greek version of the PFPS severity scale was also administered once at initial visit. Internal consistency of the translated instrument was measured using Cronbach’s α. An intraclass correlation coefficient was used to assess the test–retest reliability of the KAKPS. Concurrent validity was measured by correlating the KAKPS with the PFPS severity scale using Pearson’s correlation coefficient. Results: The results showed that the Greek KAKPS has good internal consistency (Cronbach’s α?=?0.942), test–retest reliability (ICC?=?0.921) and concurrent validity (r?>?0.7). Conclusions: This study has shown that the Greek KAKPS has good internal consistency, test–retest reliability and concurrent validity when correlated with the PFPS severity scale in adult patients with AKP for at least four weeks.

• Implications for rehabilitation

• The Greek version of the KAKPS has been found to be reliable and valid when used in adult patients with AKP for at least four weeks.

• The results of the psychometric characteristics were compatible with those of the original English version.

• The KAKPS could be applied in a Greek-speaking population to assess functional limitations and symptoms in patients aged 18–45 years old with AKP for at least four weeks.

     

The Nordic Musculoskeletal Questionnaire: cross-cultural adaptation into Turkish assessing its psychometric properties

Purpose: The purpose of this study was to linguistically and culturally adapt the Nordic Musculoskeletal Questionnaire (NMQ) for use in Turkey, and to examine the psychometric properties of this adapted version.

Method: The cross-cultural adaptation was achieved by translating the items from the original version, with back-translation performed by independent mother-tongue translators, followed by committee review. Reliability (internal consistency and test–retest) was examined for 198 participants who completed the NMQ twice (with a 1 week interval). Construct validity was examined with data from 126 participants from the same population, who completed further four questionnaires related to the body regions described in the NMQ.

Results: The internal consistency was excellent (Cronbach’s alpha?=?0.896). The test–retest reliability was examined with the prevalence-adjusted bias-adjusted kappa (PABAK) and all items showed moderate to almost perfect reliability (PABAK?=?0.57–0.90). Participants with a musculoskeletal problem in a related region had significantly more disability/pain, as assessed by the relevant questionnaires (p?Conclusions: This study provided considerable evidence that the Turkish version of the NMQ has appropriate psychometric properties, including good test–retest reliability, internal consistency and construct validity. It can be used for screening and epidemiological investigations of musculoskeletal symptoms.

Rehabilitation Complexity Scale: Italian translation and transcultural validation

Purpose: The aim of the present study was translation, cultural adaption and validation of the extended version 12 of the Rehabilitation Complexity Scale (RCS-E) in a sample of patients with stroke and total hip replacement. Method: The cross-cultural validation required RCS-E forward–backward translation, revision by an expert committee and its application in an Intensive Rehabilitation setting through a retrospective collection of data from clinical records. The evaluation of the psychometric properties was carried out by analyzing the correlations between RCS-E score and other measures (Functional Independence Measure, Braden, Morse, Cumulative Illness Rating Scale) and the assessment of reliability in terms of reproducibility (inter-observer agreement) and repeatability (intra-observer agreement). Results: The backward and forward processes of translation of the scale did not create problems of interpretation of terms. Some adaptation was required for the items nursing (N), medical care (M) and therapeutic intensity (TI) due to differences on the national health system structure. The Italian version of the scale proved to be valid, reliable with high reproducibility and repeatability. Conclusions: The Italian version RCS-E has been successfully validated, showing good psychometric properties, which partly reproduce the results obtained for the original version. However, some assumption was made for some items thus preventing possible comparison with other countries.

• Implications for Rehabilitation

• Admittance at an Intensive Rehabilitation care setting in Italy requires to evaluate the complexity of rehabilitation needs.

• The Rehabilitation Complexity Scale (RCS-E) has proved to be reliable for assessing clinical complexity and consequently for planning rehabilitation needs.

• The Italian version of RCS-E has been successfully validated, showing good psychometric properties, which reproduce the results obtained for the original version.

• The items included in the therapy intensity subscale do not fit the Italian health system rules for intensity of rehabilitation care and needs adaptation.

     

Foot and ankle ability measure to measure functional limitations in patients with foot and ankle disorders: a Chinese cross-cultural adaptation and validation

The Participation Scale: psychometric properties of a South Indian translation with hearing-impaired respondents

Abstract

Aims: The Participation Scale (P-Scale) is a widely used generic self-report measure designed to assess an individual’s participation restriction consequent to any disease condition. The present study aimed to evaluate the validity and reliability of a south Indian (Kannada language) version of the P-Scale for use with adults with hearing loss. This study is a part of an ongoing research program on the assessment of outcomes of hearing health rehabilitation with hearing aids involving Indian client groups.

Methods: One hundred and three adults with hearing loss completed the original English and the newly translated-adapted Kannada P-Scale questionnaire. Nearly half of the participants completed repeat testing of the Kannada version 15?days after the initial assessment. Along with the P-Scale, Kannada versions of the Hearing Handicap Questionnaire (HHQ) and the Assessment of Quality of Life – 4 Dimensions Questionnaire (AQoL-4D) were also administered. Based on predefined quality criteria, five different psychometric properties of the P-Scale were evaluated, together with an analysis of the Kannada P-Scale’s factor structure. The psychometric properties assessed included internal consistency, test–retest reliability, convergent validity, discriminant validity, and floor-ceiling effects.

Results: Principal component analysis indicated a four-factor complex structure, which explained 69.78% of the variance in the Kannada P-Scale. High internal consistency (Cronbach’s alpha?=?0.90) and test–retest reliability (internal consistency coefficient >0.90) were obtained. Comparisons with the HHQ (ρ?=?0.52) and AQoL-4?D (ρ?=?0.76) indicated good convergent validity. Discriminant validity among the P-Scale questions was acceptable (inter-item correlation <0.60). Floor and ceiling effects were not evident in the Kannada P-Scale.

Conclusions: The psychometric characteristics of the Kannada P-scale were found to be sufficient for use with the participant group (literate, Kannada-speaking adults with hearing loss) who were assessed in this study. Further research is required to determine generalizability of the Kannada P-Scale among other Kannada-speaking communities.

• Implications for Rehabilitation

• The Kannada version of the Participation Scale (P-Scale) can be validly used with Kannada speaking adults with hearing loss.

• The Kannada P-Scale can be used for clinical/research purposes to assess outcome (specifically, change in participation restriction) before, during, and after the hearing rehabilitation process.

• However, education and socioeconomic status may have an effect of the Kannada P-Scale results and these factors need to be further investigated prior to wider clinical use.

Transcultural adaptation and validation of Hindi version of Quebec Back Pain Disability Scale

Abstract

Purpose: To transculturally adapt the Quebec Back Pain Disability Scale for Hindi-speaking population and examine its psychometric properties in patients with low back pain.

Materials and methods: The Quebec Back Pain Disability Scale was translated and cross-culturally adapted into Hindi following international guidelines. Hindi version of the scale was completed by 120 patients with low back pain and 60 healthy controls. Patients with low back pain were also administered the Hindi-Roland Morris Disability Questionnaire and Visual Analog Scale. Psychometric evaluation included test–retest reliability, convergent and discriminative validity. Exploratory factor analysis was carried out to determine the factor structure.

Results: The factorial analysis revealed a four-factor solution (bending/carrying, ambulation/reach, prolonged postures and rest). Convergent validity was confirmed by high correlation of Hindi Quebec Back Pain Disability Scale to the Hindi version of Roland Morris Disability Questionnaire (r?=?0.77 and p?<?0.001) as well as Visual Analog Scale (r?=?0.682 and p?<?0.001) scores. Discriminative validity was established by significantly different scores for patients with low back pain and the healthy controls (35.36?±?18.6 vs. 9.13?±?6.08 and p?<?0.001). The translated version of the scale showed remarkable internal consistency (Cronbach α?=?0.98) and the intraclass correlation coefficient of test–retest reliability was excellent (ICC_2,1=0.96). MDC₉₅ and SEM scores obtained were 10.28 and 3.71, respectively.

Conclusion: The Hindi version of Quebec Back Pain Disability Scale has good test–retest reliability, discriminative and convergent validity and is appropriate for clinical and research use in Hindi-speaking low back pain patients.

• Implications for rehabilitation

• Linguistically and culturally adapted questionnaires help researchers make adequate inferences about instruments measuring health and quality of life.

• The translated version would serve as a valid research tool allowing comparability of data across cultures thus, providing opportunities for large multicenter, multicountry trials.

• A Hindi Quebec Back Pain Disability Scale version will help to improve the quality and efficacy of assessment of low back pain by developing in patients, a better understanding of the items which can be easily correlated with the activities of daily living.

Purpose: Self-efficacy plays a key role in varying areas of human conditions which can be measured by different scales. The present study was aimed to evaluate the psychometric properties of Moorong Self-Efficacy Scale (MSES) in Iranian Subjects with Physical Disability (SWPD).

Method: Data were collected by face-to-face interviews and self-report surveys from 214 subjects. The face and content validity, and reliability were evaluated. Discriminates were evaluated between the sub-groups of disability levels, physical activity, and health condition levels. The concurrent, convergent, divergent, and construct validity were assessed by short form health survey scale (SF-36), general self-efficacy scale (GSES), hospital anxiety and depression scale (HADS), respectively. Replaceable exploratory factor analysis was evaluated. SPSS software was used for statistical analysis.

Results: There were acceptable face and content validity, and reliability. Furthermore, significant correlation was found between PSES and SF-36 (p?p?=?0.02), physical activity levels (p?p?=?0.001). The correlation of Persian Self-Efficacy Scale (PSES) scores with GSES (r?=?0.61, p?R?=??0.53, p?Conclusions: The PSES is a valid, reliable and sensitive tool to measure the self-efficacy among SWPD for planning and managing of disability problems.

• Implications for rehabilitation

• Psychometric properties of the Persian version of self-Efficacy scale (PSES) appear to be similar to original, English version.

• The PSES has been shown to have validity and reliability in Persian physical disables and can be used for patients with more different types of physical disability than individuals suffering from only Spinal Cord Injury (SCI).

• The PSES can be used in clinical practice and research work to evaluate the patients’ confidence in performing daily activities.

     

Translation,cross-cultural adaptation and psychometric properties of the Back Beliefs Questionnaire in Modern Standard Arabic

Purpose To translate and cross-culturally adapt the Back Beliefs Questionnaire (BBQ) into modern standard Arabic and examine its validity, acceptability and reliability in Arabic-speaking patients with low back pain (LBP). Method The BBQ was forward, back-translated and reviewed by an expert committee. Seventeen bilingual patients completed Arabic and English BBQs. LBP patients (n?=?199) completed the Arabic BBQ. Sixty-four repeated it a week later, and 151 completed the Arabic Fear-avoidance Beliefs Questionnaire (FABQ). Results The expert committee followed advice from the developers to maintain Arabic equivalence of “back trouble(s)”. Patients found the questionnaire comprehensible and acceptable. Agreement between the English and Arabic versions of the BBQ was acceptable, ICC?= 0.65 (0.25–0.86). Most item-by-item agreement ranged from fair to moderate (K?=?0.12–0.54). Mean (SD) of BBQ, FABQ total, work and physical activity subscales were 25.31(6.13), 44.76(19.49), 21.17(10.10) and 13.95(6.65). The BBQ correlated with the FABQ at r?=??0.33, work subscale r?=??0.29 and physical activity r?=??0.30 (all p?α?=?0.73 indicated high internal consistency. Test–retest reliability was high, ICC?=?0.80 (0.68–0.87). Item-by-item agreement ranged from fair to acceptable (K?=?0.31–0.66). Conclusions The Arabic BBQ has good comprehensibility and acceptability, acceptable agreement with the English BBQ, high internal consistency and test–retest reliability. We recommend its use with Arabic-speaking LBP patient to determine their beliefs and attitudes about their back pain, as they have been shown to be important predictors of persistent LBP disability.

• Implications for Rehabilitation

• There are limited valid and reliable outcome measures for back pain in Arabic. The Back Beliefs Questionnaire (BBQ) is a tool that measures attitudes and beliefs about back pain.

• We recommend the use of our valid and reliable, translated and cross-culturally adapted tool with Arabic-speaking patients.

• The tool can measure attitudes and beliefs concerning the future consequences of LBP, with regards to recovery and return to work in this sample.

• Findings will improve back pain management options aimed at reducing back pain disability though challenging and modifying beliefs in the Middle East or with migrant populations in the West.

     

Improving the utility of the fine motor skills subscale of the comprehensive developmental inventory for infants and toddlers: a computerized adaptive test

Abstract

Aim: This study aimed at improving the utility of the fine motor subscale of the comprehensive developmental inventory for infants and toddlers (CDIIT) by developing a computerized adaptive test of fine motor skills.

Methods: We built an item bank for the computerized adaptive test of fine motor skills using the fine motor subscale of the CDIIT items fitting the Rasch model. We also examined the psychometric properties and efficiency of the computerized adaptive test of fine motor skills with simulated computerized adaptive tests.

Results and conclusions: Data from 1742 children with suspected developmental delays were retrieved. The mean scores of the fine motor subscale of the CDIIT increased along with age groups (mean scores?=?1.36–36.97). The computerized adaptive test of fine motor skills contains 31 items meeting the Rasch model’s assumptions (infit mean square?=?0.57–1.21, outfit mean square?=?0.11–1.17). For children of 6–71 months, the computerized adaptive test of fine motor skills had high Rasch person reliability (average reliability >0.90), high concurrent validity (rs?=?0.67–0.99), adequate to excellent diagnostic accuracy (area under receiver operating characteristic?=?0.71–1.00), and large responsiveness (effect size?=?1.05–3.93). The computerized adaptive test of fine motor skills used 48–84% fewer items than the fine motor subscale of the CDIIT. The computerized adaptive test of fine motor skills used fewer items for assessment but was as reliable and valid as the fine motor subscale of the CDIIT.

• Implications for Rehabilitation

• We developed a computerized adaptive test based on the comprehensive developmental inventory for infants and toddlers (CDIIT) for assessing fine motor skills.

• The computerized adaptive test has been shown to be efficient because it uses fewer items than the original measure and automatically presents the results right after the test is completed.

• The computerized adaptive test is as reliable and valid as the CDIIT.

     

Oropharyngeal dysphagia in children with cerebral palsy: comparisons between a high- and low-resource country

Purpose: There is paucity of research investigating oropharyngeal dysphagia (OPD) in young children with cerebral palsy (CP), and most studies explore OPD in high-resource countries. This study aimed at determining the proportion and severity of OPD in preschool children with CP in Bangladesh, compared to Australia.

Method: Cross-sectional, comparison of two cohorts. Two hundred and eleven children with CP aged 18–36 months, 81 in Bangladesh (mean?=?27.6 months, 61.7% males), and 130 in Australia (mean?=?27.4 months, 62.3% males). The Dysphagia Disorders Survey (DDS) – Part 2 was the primary OPD outcome for proportion and severity of OPD. Gross motor skills were classified using the Gross Motor Function Classification System (GMFCS), motor type/distribution.

Results: (i) Bangladesh sample: proportion OPD?=?68.1%; severity?=?10.4 SD?=?7.9. Australia sample: proportion OPD?=?55.7%; severity?=?7.0 SD?=?7.5. (ii) There were no differences in the proportion or severity of OPD between samples when stratified for GMFCS (OR?=?2.4, p?=?0.051 and β?=?1.2, p?=?0.08, respectively).

Conclusions: Despite overall differences in patterns of OPD between Bangladesh and Australia, proportion and severity of OPD (when adjusted for the functional gross motor severity of the samples) were equivalent. This provides support for the robust association between functional motor severity and OPD proportion/severity in children with CP, regardless of the resource context.

• Implications for Rehabilitation

• The proportion and severity of OPD according to gross motor function level were equivalent between high- and low-resource countries (LCs).

• Literature from high-resource countries may be usefully interpreted by rehabilitation professionals for low-resource contexts using the GMFCS as a framework.

• The GMFCS is a useful classification in LCs to improve earlier detection of children at risk of OPD and streamline management pathways for optimal nutritional outcomes.

• Rehabilitation professionals working in LCs are likely to have a caseload weighted towards GMFCS III–V, with less compensatory OPD management options available (such as non-oral nutrition through tubes).

     

Assessment of spasticity after stroke using clinical measures: a systematic review

Abstract

Purpose: To identify and appraise the literature on clinical measures of spasticity that has been investigated in people after stroke. Methods: The literature search involved four databases (PubMed, CINAHL, Embase and The Cochrane Library) up to February 2014. The selected studies included those that aimed to measure spasticity using a clinical assessment tool among adult patients post-stroke. Two independent raters reviewed the included articles using a critical appraisal scale and a structured data extraction form. Results: A total of 40 studies examining 15 spasticity assessment tools in patients post-stroke were reviewed. None of the reviewed measurement tools demonstrated satisfactory results for all psychometric properties evaluated, and the majority lacked evidence concerning validity and absolute reliability. Conclusion: This systematic review found limited evidence to support the use of most of clinical measures of spasticity for people post-stroke. Future research examining the application and psychometric properties of these measures is warranted.

• Implications for Rehabilitation

• There is a need for objective clinical tools for measuring spasticity that are clinically feasible and easily interpreted by clinicians.

• This review identified various clinical measures of spasticity that have been investigated in people after stroke.

• Insufficient evidence of psychometric properties precludes recommending one tool over the others.

• Future research should focus on investigating the psychometric properties of clinical measures of spasticity.

Purpose: The study aimed at assessing the relationship between various Mini Mental State Examination (MMSE) subdomains and rehabilitation achievements in post-acute hip-fractured patients.

Method: Six hundred and five hip-fractured patients admitted during 2010–2013 to a post-acute geriatric rehabilitation center were included in the study. Main outcome measures were the Functional Independence Measure (FIM) instrument, the motor FIM (mFIM), the Montebello Rehabilitation Factor Score (MRFS) on the mFIM and length of stay (LOS). A logistic regression analysis tested the predictive value of MMSE subdomains for achieving a satisfactory functional gain (mFIM MRFS >30%) on operated patients admitted from community.

Results: Of all the six MMSE subdomains, place orientation and visual construction demonstrated significant predictive values for rehabilitation outcome. Patients who did not err on place orientation and visual construction MMSE domains had better probabilities [(OR 1.28, 95%CI, 1.05–1.58; p?=?0.017); (OR 2.15, 95%CI, 1.28–3.59; p?=?0.004), respectively] of achieving better rehabilitation achievements. Similar results were obtained for cognitively impaired patient groups [(OR 1.40 95%CI, 1.11–1.77; p?=?0.005); (OR 2.47, 95%CI, 1.15–5.30; p?=?0.021), respectively]. For the cognitively intact patient group, the variables with significant predictive value were time orientation and visual construction MMSE subdomains [(OR 2.26, 95%CI, 1.18–4.33; p?=?0.014); (OR 2.87, 95%CI, 1.16–7.09; p?=?0.022), respectively].

Conclusions: Post-acute hip-fractured patients scoring normally on place orientation and visual construction MMSE subdomains have a better chance of achieving favorable rehabilitation outcome.

• Implications for Rehabilitation

• Post-acute hip-fractured patients have a better chance to achieve a favorable rehabilitation outcome when scoring normally on place orientation and visual construction MMSE subdomains.

• Patients having difficulties in orientation and visual construction may need more rehabilitation time as they lack planning and organizational capacity to follow instructions.

• Assessing MMSE subdomains may reveal subtle cognitive impairment in patients scored within the normal range on the MMSE test.

• Identifying subtle cognitive impairment may assist in coordinating the patients and their caregivers' expectations, efficiently allocating resources and help in advanced care planning.

     

Psychometric properties of Persian version of the Caregiver Burden Scale in Iranian caregivers of patients with spinal cord injury

Purpose: To investigate the psychometric properties of the Persian version of Caregiver Burden Scale (CBS) in caregivers of patients with spinal cord injury.

Methods: This is a cross-sectional study. After a forward–backward translation, the CBS was administered to 110 caregivers of patients with spinal cord injury (men?=?60, women?=?50). Factor structure was evaluated by confirmatory factor analysis. The Internal consistency and test–retest reliability of the CBS were examined using Cronbach’s α and the intraclass correlation coefficient, respectively. Construct validity was assessed by examining the relationship among CBS and the World Health Organization Quality of Life, and the Beck Depression Inventory.

Results: The results of confirmatory factor analysis provided support for a five-factor model of CBS. All subscales of CBS revealed acceptable internal consistency (0.698–0.755), except for environment subscale (0.559). The CBS showed adequate test–retest reliability for its subscales (0.745–0.900). All subscales of CBS significantly correlated with both Beck Depression Inventory and World Health Organization Quality of Life, confirming construct validity.

Conclusions: The Persian version of the CBS is a valid and reliable measure for assessing burden of care in caregivers of patients with spinal cord injury.

• Implications for Rehabilitation

• Spinal cord injury leads to depression, high levels of stress and diminished quality of life due to the high physical, emotional, and social burdens in caregivers.

• Persian version of the Caregiver Burden Scale is a valid and reliable tool for assessing burden in Iranian caregivers of patients with spinal cord injury.

     

The Spanish lower extremity functional scale: A reliable,valid and responsive questionnaire to assess musculoskeletal disorders in the lower extremity

Abstract

Purpose: The Lower Extremity Functional Scale (LEFS) is a widely used questionnaire to evaluate the functional impairment of a patient with a disorder of one or both lower extremities. It also can be used to monitor the patient over time and to evaluate the effectiveness of an intervention. Nevertheless there is no Spanish version of the LEFS, so the aim of this study was the translation and cross-cultural adaption of the Spanish version of the LEFS and to evaluate its psychometrics properties. Methods: The questionnaire was cross cultural adapted into Spanish. The psychometric properties tested in the Spanish version of the LEFS were: internal consistency, test–retest reliability, constructs validity, discriminative validity, responsiveness, concurrent validity and floor and ceiling effects in 132 participants seeking for treatment due to lower extremity dysfunction. Results: The Spanish version of the LEFS had high internal consistency (Cronbach’s α?=?0.989), test–retest reliability (ICC?=?0.998, 95% CI: 0.996–0.999) and presented a high correlation with the SF-36 (36-Item Short-Form Health Survey) especially with the physical function and pain subscales. The construct validity showed a single factor that account for 84.95% of the variance. The standard error of measurement of the Spanish version of the LEFS was 0.88 scale points (95% CI) and the minimal detectable change was 2.18 scale points (95% CI). The sample, collected from five Spanish physical therapy centers, was divided in groups (acute, sub-acute and chronic subjects). Within group changes showed a significant improvement on the LEFS score (p?<?0.001) and effect sizes were large in all conditions. The LEFS allowed to distingue between acute and not acute conditions; for this criterion ROC curve was performed at baseline (area under the curve [AUC]?=?0.95). There was no floor or ceiling effects. Conclusions: The Spanish version of the LEFS has been shown to be a valid and reliable tool to assess musculoskeletal dysfunction in the lower extremity that could be used with Spanish speaker population.

• Implications for Rehabilitation

• Cross-cultural adaptation of a self-reported questionnaire to evaluate musculoskeletal lower extremity disorders in the Spanish population.

• To provide Spanish clinicians and physiotherapists a useful tool to assess the lower extremity function.

• To provide Spanish researchers a valid tool for research on lower extremity function: patient’s improvement due to treatment, compare results obtained between populations, treatment.
