Reliability and validity of smartphone applications to measure the spinal range of motion: A systematic review.

Introduction: The objective of this study is to conduct a systematic review on the reliability and validity of various smartphone applications for spinal range of motion (ROM) measurements.Methods: Eleven studies were selected following an electronic search of PubMed, CINAHAL, Medline, Embase and SPORTDiscus. Quality appraisals of selected studies were conducted using a standardized appraisal tool.Results: Most studies demonstrated a good intra- and inter-rater reliability, as well as validity in more than 50% of joint movements. At the same time, relative reliability/validity outcomes (e.g. interclass correlation co-efficient) were stronger than absolute reliability/validity outcomes (e.g. mean differences, limits of agreement). Spinal rotation movement showed less reliability and validity when compared to other spinal movements.ConclusionsːResult of the study supports the use of smartphone applications for ROM measurements of spinal joints. However, we cannot advocate the most appropriate application for spinal ROM measurement or suggest which application is superior to all others. As clinicians have multiple options in selecting applications, it is recommended they use applications that have proven reliable and valid for that particular joint. Data from this study provides clinicians with evidence-based research on smartphone devices for measuring spinal joint ROM in clinical settings.

Effect of shoulder stability exercises on hand grip strength in patients with shoulder impingement syndrome.

Background: Shoulder impingement syndrome (SIS) is the second most common musculoskeletal condition that causes shoulder pain in the general population. Shoulder girdle muscle imbalance and posterior capsule tightness have been implicated as contributing factors. Objective: The purpose of this study was to investigate the effect of shoulder stability exercises (SSEs) on hand grip strength in patients with unilateral SIS. Methods: A total of 16 patients with a mean age of 32 ± 9.3 years diagnosed with stage II unilateral SIS participated in this study. A standardized SSE programme was conducted in the clinic under the direct 1-to-1 supervision of a physical therapist thrice weekly for 4 weeks for a total of 12 sessions on the affected and non-affected shoulders. The effect of the SSE programme on isometric hand grip strength was analysed. Results: A significant difference (p = .016) was observed in the hand grip strength of the affected shoulder side before and after the intervention, but no significant difference (p = 1.0) was found in the hand grip strength of the non-affected shoulder side post-intervention. Conclusion: The reduction in isometric hand grip strength of the affected shoulder side compared to that of the non-affected shoulder side in the same subject before the intervention shows that SIS significantly affects the hand grip strength of the affected side. SSEs significantly affect the isometric hand grip strength of SIS patients.

Comparison of the effects of short-duration wrist joint splinting combined with physical therapy and physical therapy alone on the management of patients with lateral epicondylitis.

BACKGROUND: Lateral epicondylitis (i.e., tennis elbow) is a condition caused by overuse of the arm, which can result in elbow pain. Recent evidence has shown wrist joint splinting as an effective intervention for people with lateral epicondylitis. AIM: The purpose of this study was to compare the effect of a 3 week wrist joint splinting and physical therapy intervention versus a standard physical therapy intervention on pain, wrist range of motion (ROM), and grip strength in people with lateral epicondylitis. DESIGN: Randomized clinical trial. SETTING: University hospital outpatient clinics. POPULATION: Forty participants diagnosed with lateral epicondylitis. METHODS: The participants were randomized into 2 groups. The standard care group followed a treatment program consisting of stretching exercises for the wrist extensors, ultrasonic therapy, and deep friction massage on the proximal attachment of the wrist extensor muscles. The intervention group followed a standard wrist joint splinting program in addition to the physical therapy program that the standard care group received. Participants in both groups received treatment 3 times per week for 3 weeks. The outcome measures were pain intensity, wrist extension ROM, wrist flexion ROM, and grip strength. Each outcome measure was assessed at baseline and after completion of the intervention. RESULTS: There were no significant between-group differences at baseline. After the treatment period, the intervention group showed statistically significant improvement in pain intensity. Other outcomes also improved including wrist flexion ROM, wrist extension ROM, and grip strength in comparison to the standard care group. CONCLUSIONS: Using wrist joint splinting in addition to physical therapy for a short duration is effective for improving pain intensity. The evidence from this study indicates that wrist joint splinting and physical therapy may also be effective for improving wrist ROM and grip strength in the treatment of patients with lateral epicondylitis, although more research is need in this area. CLINICAL REHABILITATION IMPACT: Wrist joint splinting is an effective intervention that can be applied in clinical rehabilitation practices for people with lateral epicondylitis.

Efficacy of complex training on angular velocity of shoulder in collegiate basketball players.

BACKGROUND: Shoulder internal rotation angular velocity at the time of ball release is a crucial factor deciding the ball velocity in throwing. Even though there are some studies conducted regarding the effectiveness of complex training on the lower limb, the researchers has not given much attention to the upper limb. OBJECTIVE: To investigate the efficacy of a complex training program combining plyometric and weight training on the angular velocity of shoulder with a program composed of only plyometric training or only weight training. METHODS: It was a pre-test - post-test experimental study. Thirty healthy male collegiate basketball players were randomly divided into three groups: Plyometric training group (n= 10), weight training group (n= 10), complex training group which includes both plyometric training and weight training (n= 10). The training was given for six weeks with a frequency of two days per week. Subjects were measured for angular velocity of shoulder before and after the training period by using Biodex upper body cycle. All the three groups were compared by using one way ANOVA. Post-hoc fisher least significant difference (LSD) test was used to find out the difference between groups. RESULTS: All the groups showed a significant gain in angular velocity after the six-week training period (p< 0.05). However, the improvement attained in complex training group were significantly greater than other training groups (p< 0.05). CONCLUSION: The study concluded that a combination of plyometric and weight training (complex training) can improve the angular velocity of shoulder in male collegiate basketball players more than plyometric or weight training alone.

Functional outcomes of kinesio taping versus standard orthotics in the management of shin splint.

BACKGROUND: Exercise-related or lower-limb overuse injury characterized by pain located between the knee and the ankle that occurs during activity is commonly referred to as shin splint. Hyperpronation is considered the ultimate culprit in the development of overuse injuries such as shin splint. This study endeavors to compare the functional outcomes of the most commonly used anti-pronation techniques, kinesio taping and standard orthotics. METHODS: A total of 40 subjects (mean age, 24.16±2.6 years) with symptoms of shin splint participated in the current study. These subjects were randomly allocated to two groups (N.=20) and underwent anti-pronation kinesio taping and standard orthotics, respectively. The functional outcomes were assessed using the navicular drop test, visual analog scale, and hop distance. RESULTS: The kinesio taping intervention group showed significant improvements in pain and hop distance compared to the standard orthotics intervention group, whereas an insignificant intergroup difference was observed for the navicular drop test. Patients in both groups benefited, but the response to kinesio taping was better than that to orthotics. CONCLUSIONS: Kinesio taping played a vital role in improving functional outcomes compared to orthotics by reducing pain and improving functional activity in patients with shin splint; however, navicular drop correction did not occur using either intervention.

Treatment of knee osteoarthritis in relation to hamstring and quadriceps strength.

[Purpose] To assess the effect of hamstring and quadriceps strengthening exercises on pain intensity, gait velocity, maximum isometric strength, and activities of daily living of patients with knee osteoarthritis (OA). [Subjects and Methods] A total of 20 patients with knee OA, 50 to 65 years of age (57.65 ± 4.78 years), received hot packs, strengthening exercises for the quadriceps and the hamstring muscles and stretching exercises for hamstring muscles. Outcome measures included: the Western Ontario and McMaster Universities OA index questionnaire (WOMAC) scores for assessing health status and health outcomes of knee OA; self-reported pain intensity scores, measured using a visual analogue scale; the 50 ft walk test (a measure of gait velocity and function); and handheld dynamometry (a tool used to measure maximum isometric strength of knee extension and flexion). [Results] There was a significant difference between pre- and post-intervention measures of pain intensity, 50 ft walk times, hamstring strength, and quadriceps strength. Significant differences in WOMAC measures were also observed in the subscales of pain, stiffness and physical function, as well as WOMAC total scores. [Conclusion] Strengthening the hamstring muscles in addition to strengthening the quadriceps muscles proved to be beneficial for perceived knee pain, range of motion, and decreasing the limitation of functional performance of patients with knee OA.
