RESUMEN
OBJECTIVE: To evaluate the efficacy of a rehabilitation programme including balance task-specific training in improving physical function, pain, activities of daily living (ADL), balance and quality of life in subjects after a hip fracture. DESIGN: Randomized controlled trial. SUBJECTS: A total of 52 older subjects selected for internal fixation due to extra-capsular hip fracture were randomized to be included in an experimental ( n = 26) and control group ( n = 26). INTERVENTIONS: The experimental group underwent a rehabilitation programme based on balance task-specific training. The control group underwent general physiotherapy, including open kinetic chain exercises and walking training. Both groups individually followed programmes of 90-minute sessions five times/week for three weeks. OUTCOME MEASURES: The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), a Pain Numerical Rating Scale, the Berg Balance Scale, the Functional Independence Measure and the 36-item Short-Form Health Survey. The participants were evaluated before and after training, and after 12 months. RESULTS: Significant effects of time, group and time × group were found for all outcome measures in favour of the experimental group. A clinically important between-group difference of 25 points was achieved after training and at follow-up in terms of the primary outcome (WOMAC function before treatment, after treatment and at follow-up was 84.8 (3.7), 39.8 (4.9) and 35.7 (6.2) for the experimental group and 80.9 (5.7), 65.2 (7.1) and 61.0 (11.1) for the control group). CONCLUSION: An inpatient rehabilitation programme based on balance task-specific training is useful in improving physical function, pain, ADL and quality of life in older patients after hip fracture.

PURPOSE: To develop and validate NeckPix(©), a multi-image instrument for assessing daily activities in the context of pain-related fear, in order to allow its use in patients with chronic neck pain (NP). METHODS: The measure was developed by means of item generation followed by reduction/selection. The psychometric testing included exploratory factor analysis; content validity by investigating clarity, specificity, appropriateness for the target population, relevance and completeness; reliability by internal consistency (Cronbach's alpha) and test-retest stability (intra-class coefficient correlation, ICC); and construct validity by comparing NeckPix with the Tampa Scale of Kinesiophobia (TSK), the Pain Catastrophising Scale (PCS), the Neck Disability Index (NDI) and a Numerical Rating Scale of pain intensity (NRS) (Pearson's correlation). RESULTS: The measure, which includes ten images used to assess everyday activities in the context of pain-related fear, was administered to 118 subjects with chronic non-specific NP, and proved to be acceptable and feasible. Factor analysis revealed a one-factor solution (which explained 71.12 % of variance). The content of the images was considered adequate, appropriate for the target population, comprehensive, and relevant for evaluating activity-related kinesiophobia. The instrument's internal consistency was good (α = 0.954), as was its test-retest stability (ICC 0.979). Construct validity demonstrated a close correlation with the TSK (r = 0.759), and moderate correlations with the PCS (r = 0.583), the NDI (r = 0.520), and a NRS (r = 0.455). CONCLUSION: NeckPix(©), which was successfully developed following international recommendations, proved to have a good factorial structure and satisfactory psychometric properties. Its use is recommended for research purposes.

PURPOSE: To evaluate the responsiveness and minimal important changes (MICs) for the Italian Neck Disability Index (NDI) and Neck Pain Disability Scale (NPDS) as well as which questionnaire was the most responsive in subjects with chronic neck pain (NP). METHODS: At the beginning and end of an 8-week rehabilitation programme, 200 patients completed the NDI and NPDS. After the programme, the global perceived effect (GPE) was also evaluated and collapsed to produce a dichotomous outcome (improved vs. stable). Responsiveness was calculated by distribution [effect size (ES); standardised response mean (SRM)] and anchor-based methods (ROC curves; correlations between change scores of NPDS and NDI, and GPE). ROC curves were also used to compute the best cutoff levels between improved and stable subjects (MICs). RESULTS: The ES was 0.66 and 0.73, and the SRM was 1.09-1.26 for the NDI and NPDS, respectively. The ROC analyses revealed AUCs of 0.96 and 0.91 for the NDI and NPDS, respectively; the MICs were 7-percentage points for the NDI (sensitivity: 98%; specificity: 81%) and 10 for NPDS (93; 83%), showing equivalent responsiveness properties. Baseline NPDS scores did not affect MIC estimate for the NPDS, while, for the NDI, higher MICs were found for patients with worst disability levels. Correlations between change scores of the NDI and NPDS and GPE were, respectively, high (0.71) and moderate (0.59). CONCLUSIONS: The Italian NDI and NPDS were equally sensitive in detecting clinical changes in subjects with chronic NP undergoing rehabilitation. We recommend taking the MICs into account when assessing patient improvement or planning studies in this clinical context.

PURPOSE: There is growing interest in measures that assess upper-limb lymphedema after breast cancer. Since no validated Italian version of the Lymphedema Quality of Life Questionnaire for upper limbs (LYMQOL-UL) exists, we aimed to culturally adapt and validate an Italian version (LYMQOL-UL-IT) in order to allow its use in Italian patients. MATERIALS AND METHODS: The LYMQOL-UL-IT was developed by means of forward-backward translation, review by an expert committee and a test of the pre-final version to evaluate its comprehensibility. The psychometric testing included reliability by internal consistency (Cronbach's alpha) and test-retest reliability (intraclass correlation coefficient, ICC(2.1)), measurement error by calculating the minimum detectable change (MDC95), construct validity by confirmatory factor analysis, and evaluation of a priori hypotheses about the correlations between the four LYMQOL-UL domains, single items of the LYMQOL-UL, and measures of health-related quality of life and pain intensity (Spearman's rank correlation coefficient). RESULTS: The consensus-based version of LYMQOL-UL-IT was administered to 139 patients with upper-limb stable secondary iatrogenic lymphedema after breast cancer. The adapted questionnaire was well accepted as it was completed in less than 10 min, without missing answers or comprehension problems. Internal consistency was acceptable (α = 0.92-0.95). Test-retest reliability was good-to-excellent (ICC(2.1) = 0.73-0.96). The MDC95 for the four domains of the questionnaire was as follows: 0.64 scale points for Function, 0.40 for Appearance, 0.53 for Symptoms, and 0.81 for Mood. Factor analysis confirmed a 4-dimensional structure as originally conceived and the a priori hypotheses were met. CONCLUSION: The LYMQOL-UL-IT is reliable, sensitive to change and valid in patients with upper-limb stable secondary iatrogenic lymphedema after breast cancer. It can be used for clinical and research purposes.Implications for rehabilitationLymphedema is a frequently unnoticed clinical condition that not only impacts physical functioning but often restricts the health-related quality of life in breast cancer survivors.The Italian version of the Lymphedema Quality of Life Questionnaire for upper limbs (LYMQOL-UL-IT) is reliable, sensitive to change and valid in patients with upper-limb lymphedema after breast cancer.The LYMQOL-UL-IT tool can be recommended for clinical and research purposes.

Mobile health apps are growing constantly in number and popularity. Some mobile apps are used for clinical assessment, and consequently need to be verified and validated appropriately, along with the mobile platform, to ensure their safe and effective operation. We review the current literature on available smartphone goniometric apps validated for joint angle measurement and their main psychometric characteristics. A literature search of Medline and Scopus databases was performed to select papers on smartphone commercial apps validated for joint angle measurement and relevant to Physical Medicine and Rehabilitation. A platform search verified whether the selected apps were still available for download. The literature search identified 126 papers in Medline and 113 in Scopus, 49 of which were selected. They dealt with the validation of 23 apps, eight of which were no longer available and therefore excluded from the review. Psychometric characteristics of the selected apps were robust, but heterogeneity of the studies did not enable comparisons between apps to identify the most valid one. The increase in the number of apps and validation studies highlights the growing interest in this new approach for measuring body angles. Given the precarious commercial availability of some apps, when research is the goal, it is advisable to select apps with the longest durability. A need continues to exist for validation studies on available apps focused on goniometric measurement in gait or during performance of therapeutic exercises in neurological and orthopedic disorders.

PURPOSE: To cross-culturally adapt and psychometrically analyse the Italian version of the Trunk Impairment Scale on acute (cohort 1) and chronic stroke patients (cohort 2). METHODS: The Trunk Impairment Scale was culturally adapted in accordance with international standards. The psychometric testing included: internal consistency (Cronbach's alpha), inter- and intra-rater reliability (intraclass correlation coefficient; standard error of measurement and minimal detectable change), construct validity by comparing Trunk Impairment Scale score with Barthel Index, motor subscale of Functional Independence Measure, and Trunk Control Test (Pearson's correlation), and responsiveness (Effect Size, Effect Size with Guyatt approach, standardized response mean, and Receiver Operating Characteristics curves). RESULTS: The Trunk Impairment Scale was administered to 125 and 116 acute and chronic stroke patients, respectively. Internal consistency was acceptable (α > 0.7), inter- and intra-rater reliability (ICC > 0.9, Minimal Detectable Change for total score < 1.6 in cohort 1 and < 1.1 in cohort 2) were excellent. The construct validity showed acceptable correlations (r > 0.4) with all scales but the motor Functional Independence Measure in cohort 2. Distribution-based methods showed large effects in cohort 1 and moderate to large effects in cohort 2. The Minimal Important Difference was 3.5 both from patient's and therapist's perspective in cohort 1 and 2.5 and 1.5 from patient's and therapist's perspective, respectively, in cohort 2. CONCLUSION: The Trunk Impairment Scale was successfully translated into Italian and proved to be reliable, valid, and responsive. Its use is recommended for clinical and research purposes. Implications for Rehabilitation Trunk control is an essential part of balance and postural control, constituting an important prerequisite for daily activities and function. The TIS administered in subjects with subacute and chronic stroke was reliable, valid and responsive. The TIS is expected to help clinicians and researchers by identifying key functional processes related to disability in people with subacute and chronic stroke.
