Smartphone Applications to Perform Body Balance Assessment: a Standardized Review.

Body balance disorders are related to different injuries that contribute to a wide range of healthcare issues. The social and financial costs of these conditions are high. Therefore, quick and reliable body balance assessment can contribute to the prevention of injuries, as well as enhancement of clinical rehabilitation. Moreover, the use of smartphone applications is increasing rapidly since they incorporate different hardware components that allow for body balance assessment. The present study aims to show an analysis of the current applications available on Google Play StoreTM and iTunes App StoreTM to measure this physical condition, using the Mobile Application Rating Scale (MARS). Three iOS and two Android applications met the inclusion criteria. Three applications have scientific support, Balance test YMED, Balance Test by Slani, and Sway. Furthermore, according to MARS, the main scores for each evaluated domain were: Engagement (2.04), Functionality (3.8), Esthetics (3.53), and Information (3.80). The reviewed applications targeted to assess body balance obtained good mean scores. Sway is the app with highest scores in each MARS domain, followed by iBalance Fitness and Gyrobalance.

Myofascial Induction Effects on Neck-Shoulder Pain in Breast Cancer Survivors: Randomized, Single-Blind, Placebo-Controlled Crossover Design.

OBJECTIVES: To (1) investigate the immediate effects of myofascial induction (MI), with placebo electrotherapy as a control, on perceived pain, cervical/shoulder range of motion (ROM), and mood state in breast cancer survivors (BCSs) with shoulder/arm morbidity; and (2) examine the relationships between pain modifications and cervical/shoulder ROM on the side affected by breast cancer. DESIGN: Randomized, single-blind, placebo-controlled crossover study. SETTING: Physical therapy laboratory. PARTICIPANTS: BCSs (N=21) who had a diagnosis of stage I-IIIA breast cancer and had completed adjuvant therapy (except hormonal treatment). INTERVENTION: During each session, the BCSs received either an MI (fascial unwinding) intervention focused on the upper limb area following the Pilat approach or placebo pulsed shortwave therapy (control group). Each session lasted 30 minutes, and an adequate washout period of 4 weeks between sessions was established. MAIN OUTCOME MEASURES: The visual analog scale (VAS) for pain and anxiety, shoulder-cervical goniometry for ROM, the Profile of Mood States for psychological distress, and the Attitudes Towards Massage Scale were used. RESULTS: An analysis of covariance (ANCOVA) revealed significant time × group interactions for VAS affected arm (P=.031) but not for VAS cervical (P=.332), VAS nonaffected arm (P=.698), or VAS anxiety (P=.266). The ANCOVA also revealed significant interactions for affected shoulder flexion (P<.001), abduction (P<.001), external rotation (P=.004), and internal rotation (P=.001). Significant interactions for affected cervical rotation (P=.022) and affected cervical lateral flexion (P=.038) were also found. A significant negative correlation was found between changes in VAS affected arm and shoulder/arm internal rotation ROM (r=-.46; P=.03). CONCLUSIONS: A single MI session decreases pain intensity and improves neck-shoulder ROM to a greater degree than placebo electrotherapy for BCSs experiencing pain.

Agreement Between Face-to-Face and Free Software Video Analysis for Assessing Hamstring Flexibility in Adolescents.

The objective of this study was to determine the level of agreement between face-to-face hamstring flexibility measurements and free software video analysis in adolescents. Reduced hamstring flexibility is common in adolescents (75% of boys and 35% of girls aged 10). The length of the hamstring muscle has an important role in both the effectiveness and the efficiency of basic human movements, and reduced hamstring flexibility is related to various musculoskeletal conditions. There are various approaches to measuring hamstring flexibility with high reliability; the most commonly used approaches in the scientific literature are the sit-and-reach test, hip joint angle (HJA), and active knee extension. The assessment of hamstring flexibility using video analysis could help with adolescent flexibility follow-up. Fifty-four adolescents from a local school participated in a descriptive study of repeated measures using a crossover design. Active knee extension and HJA were measured with an inclinometer and were simultaneously recorded with a video camera. Each video was downloaded to a computer and subsequently analyzed using Kinovea 0.8.15, a free software application for movement analysis. All outcome measures showed reliability estimates with α > 0.90. The lowest reliability was obtained for HJA (α = 0.91). The preliminary findings support the use of a free software tool for assessing hamstring flexibility, offering health professionals a useful tool for adolescent flexibility follow-up.

Agreement between telerehabilitation and face-to-face clinical outcome assessments for low back pain in primary care.

STUDY DESIGN: A descriptive study of repeated measures using a crossover design. OBJECTIVE: To determine the level of agreement between assessments obtained via telerehabilitation and those obtained by traditional face-to-face method in a population of individuals with chronic low back pain (LBP) in a primary care setting. SUMMARY OF BACKGROUND DATA: Musculoskeletal assessment using telerehabilitation has shown adequate inter- and intrarater agreement and concordance with face-to-face clinical assessment in different diseases. There have been no published studies on the reliability of a telerehabilitation system to assess LBP. METHODS: Fifteen individuals (6 males; mean age, 37 yr) with chronic LBP attended a session for a clinical interview, followed by face-to-face and real-time online telerehabilitation evaluations. There was a 30-minute interval between the 2 assessments, the order of which was randomly selected for each patient. The telerehabilitation system used an Internet application conducted via Internet connection (17 kB/s) between 2 personal computers. Real-time video connection facilitated communication between the therapist and the subject. Outcome measures included lumbar spine mobility, Sorensen test, anterior straight leg raise test, Oswestry Disability Index, visual analogue scale for pain, 12-Item Short Form Health Survey questionnaire, and Tampa Kinesiophobia Scale. RESULTS: The α reliability between face-to-face and telerehabilitation evaluations was more than 0.80 for 7 of the 9 outcome measures. Lowest reliability was for lateral flexion range of motion (α= 0.75). Very good inter- and intrarater intraclass correlation coefficients (ρ) were obtained (0.92-0.96). CONCLUSION: The findings of our pilot study suggest that this telerehabilitation system may be useful to assess individuals with chronic LBP, providing initial support for its implementation in primary care. LEVEL OF EVIDENCE: 2.
