Validity and Intra-Rater Reliability of Laser Goniometer Versus Electro-Goniometer in Measuring Shoulder Range of Motion

(1) Background: Measuring joint range of motion has traditionally occurred with a universal goniometer or expensive laboratory based kinematic analysis systems. Technological advances in wearable inertial measurement units (IMU) enables limb motion to be measured with a small portable electronic device. This paper aims to validate an IMU, the ‘Biokin’, for measuring shoulder range of motion in healthy adults; (2) Methods: Thirty participants completed four shoulder movements (forward flexion, abduction, and internal and external rotation) on each shoulder. Each movement was assessed with a goniometer and the IMU by two testers independently. The extent of agreement between each tester’s goniometer and IMU measurements was assessed with intra-class correlation coefficients (ICC) and Bland-Altman 95% limits of agreement (LOA). Secondary analysis compared agreement between tester’s goniometer or IMU measurements (inter-rater reliability) using ICC’s and LOA; (3) Results: Goniometer and IMU measurements for all movements showed high levels of agreement when taken by the same tester; ICCs > 0.90 and LOAs < ±5 degrees. Inter-rater reliability was lower; ICCs ranged between 0.71 to 0.89 and LOAs were outside a prior defined acceptable LOAs (i.e., > ±5 degrees); (4) Conclusions: The current study provides preliminary evidence of the concurrent validity of the Biokin IMU for assessing shoulder movements, but only when a single tester took measurements. Further testing of the Biokin’s psychometric properties is required before it can be confidently used in routine clinical practice and research settings.

This is a preliminary study to investigate the feasibility of electronic moxibustion in breast cancer patients with upper limb lymphedema. As current treatment options for lymphedema are unsatisfactory and time consuming, there have been attempts to manage symptoms using integrative treatments. Electronic moxibustion was developed to compensate for the shortcomings of conventional moxibustion and is widely used in clinical practice. However, there have been no studies on using electronic moxibustion in breast cancer-related lymphedema. To investigate the feasibility of electronic moxibustion in treating breast cancer-related lymphedema, this study included subjects who completed primary cancer treatment at least 6 months ago and had more than 10 mm difference in arm circumference of upper limbs. All subjects were assigned to the treatment group. Subjects were treated with 16 sessions (30 minutes/session) of electronic moxibustion for 8 weeks followed by 4 weeks of follow-up. For outcome measures, upper limb circumferences, shoulder range of motion, bioimpedance analysis, and quality of life questionnaire were assessed. All 10 subjects completed the study. The effective index showed 38.21% reduction after treatment ( P = .0098) and 29.35% ( P = .0039) after 4 weeks of follow-up compared to the baseline. The reduction of lymphedema was most prominent at 10 cm above the elbow crease, where the mean reduction of circumference difference was 7.5 mm ( P = .0430) and continued to improve after treatment (mean reduction of 8.3 mm, P = .0156). There was significant improvement in shoulder range of motion only in flexion and internal rotation at week 9. There were 7 adverse events, and most were irrelevant to the treatment. Only 1 participant had a mild burn on the acupuncture point. Here, we demonstrate for the first time that electronic moxibustion treatment is a feasible treatment for breast cancer-related lymphedema. Electronic moxibustion may reduce differences in upper limb circumference and improve shoulder range of motion. A future comparative clinical trial is needed to confirm the clinical efficacy of this treatment.

BACKGROUND: Persisting shoulder stiffness adversely affects quality of life by causing pain and motion restrictions especially in patients with diabetes. OBJECTIVE: The aim of this study was to evaluate the outcomes of arthroscopic capsular release in patients with idiopathic shoulder stiffness. METHOD: A literature search was conducted in electronic databases and studies were selected by following precise eligibility criteria. Random-effects meta-analyses were performed to estimate the changes at latest follow-up in scores of the Constant, American Shoulder and Elbow Surgeons (ASES), and University of California at Los Angelis (UCLA) scales, Visual Analogue Scale (VAS), and shoulder range of motion. RESULTS: Nineteen studies were included. The follow-up duration was 42 months [95% confidence interval (CI): 32, 51]. Improvements in scores of the Constant, ASES, UCLA scales, and VAS were 48.3 [95% CI: 38.0, 58.6], 44.6 [95% CI: 24.6, 64.6], 19.3 [95% CI: 16.6, 22.0], and -6.1 [95% CI: -6.9, -5.4] respectively (P< 0.05 all). Improvements in the shoulder range of motion were: abduction 82.0 [95% CI: 65.0, 98.9]; forward flexion 75.9 [95% CI: 59.7, 92.1]; external rotation 43.2 [95% CI: 37.5, 49.0]; and internal rotation 25.4 [95% CI: 15.2, 35.5] degrees; P< 0.05 all). CONCLUSION: Arthroscopic capsular release effectively improves shoulder function in patients with idiopathic shoulder stiffness.

AbstractCurrently it is hypothesized that increased body mass index may contribute to overuse injuries. Thus, if hip or shoulder range of motion is affected by body mass index, pitchers may be placing additional stress on joints as they seek to pitch at maximal velocity. The purpose of this study was to examine if range of motion at the hips and shoulders were related to body mass index classification. A sample of 147 female softball pitchers (17.0±4.2 years; 167.6±11.8 cm; 70.6±17.5 kg; body mass index=24.8±4.7 kg/m2) participated. Bilateral hip and shoulder range of motion were assessed. Multivariate analysis of variance results indicated body mass index [Wilks’ Λ=0.742, F=1.722, p=0.014, η2=0.095] significantly affected range of motion of the shoulder and hip. Post hoc results indicated the underweight group had significantly more range of motion than the obese group in hip internal range of motion on both the throwing side (mean difference=12.39, p=0.005) and glove side (mean difference=11.98, p=0.004). Although body composition is not overly emphasized among softball pitchers, the current study reveals excess weight may inhibit proper mechanics. Coaches, athletic trainers, strength and conditioning personnel, and athletes should acknowledge the role that body composition can play in affecting pitch outcomes.
