Measurement of Shoulder Range of Motion in Patients with Adhesive Capsulitis Using a Kinect

Range of motion (ROM) measurements are essential for the evaluation for and diagnosis of adhesive capsulitis of the shoulder (AC). However, taking these measurements using a goniometer is inconvenient and sometimes unreliable. The Kinect (Microsoft, Seattle, WA, USA) is gaining attention as a new motion detecting device that is nonintrusive and easy to implement. This study aimed to apply Kinect to measure shoulder ROM in AC; we evaluated its validity by calculating the agreement of the measurements obtained using Kinect with those obtained using goniometer and assessed its utility for the diagnosis of AC. Both shoulders of 15 healthy volunteers and affected shoulders of 12 patients with AC were included in the study. The passive and active ROM of each were measured with a goniometer for flexion, abduction, and external rotation. Their active shoulder motions for each direction were again captured using Kinect and the ROM values were calculated. The agreement between the two measurements was tested with the intraclass correlation coefficient (ICC). Diagnostic performance using the Kinect ROM was evaluated with Cohen’s kappa value. The cutoff values of the limited ROM were determined in the following ways: the same as passive ROM values, reflecting the mean difference, and based on receiver operating characteristic curves. The ICC for flexion/abduction/external rotation between goniometric passive ROM and the Kinect ROM were 0.906/0.942/0.911, while those between active ROMs and the Kinect ROMs were 0.864/0.932/0.925. Cohen’s kappa values were 0.88, 0.88, and 1.0 with the cutoff values in the order above. Measurements of the shoulder ROM using Kinect show excellent agreement with those taken using a goniometer. These results indicate that the Kinect can be used to measure shoulder ROM and to diagnose AC as an alternative to goniometer.

Quantification of Lumbar Stability During Wall Plank-and-Roll Activity Using Inertial Sensors.

To develop a simple method of quantifying dynamic lumbar stability by evaluating postural changes of the lumbar spine during a wall plank‐and‐roll (WPR) activity while maintaining maximal trunk rigidity.

Lumbar Stability in Healthy Individuals and Low Back Pain Patients Quantified by Wall Plank-and-Roll Test

Low back pain (LBP) has been linked to the degree of lumbar stability, but evaluating lumbar stability has remained a challenge. Previous research has shown that inertial sensors could be used to quantify motor patterns during the wall plank‐and‐roll (WPR) test, and that LBP may cause deviations in movement from the general motor patterns observed in healthy individuals.

Development of a pressure sensor system for unobtrusive monitoring of abdominal muscle activities

Abstract Surface electromyogram (sEMG) is often used by to objectively measure muscular activity during rehabilitation exercises. sEMG is accurate, but it is unsuitable for uses outside the clinic, and patients can benefit from an unobtrusive device which can be readily used to ubiquitously measure abdominal muscle activation. In this study, we present a pressure sensor system which can be latched onto a belt to measure abdominal muscle activation. sEMG and pressure sensor output were measured in 15 healthy young males during isometric trunk flexion exercise (public trials registration number, KCT0002351), and the results were highly correlated (median R > 0.939). As initial contact force can change the pressure sensor sensitivity, the experiment was performed at two different levels of belt tightness, but the correlations did not significantly improve after tightening the belt, suggesting that the system can be used to ubiquitously and unobtrusively monitor abdominal muscle activity with minimal discomfort.

High-Pressure Balloon-Assisted Stretching of the Coracohumeral Ligament to Determine the Optimal Stretching Positions: A Cadaveric Study.

The coracohumeral ligament (CHL) is a thick capsular structure and markedly thickened when affected by adhesive capsulitis. Therapeutic stretching is the most commonly applied treatment for adhesive capsulitis, but optimal stretching postures for maximal therapeutic effects on the CHL have not been fully investigated.

Poster 176 Relationships between Chronic Low Back Pain and Sarcopenia in the Elderly

Objective: Current therapeutic options for chronic low back pain (LBP) of discogenic origin are limited. The potential for complications associated with both surgery and more conservative therapy, such as opioid use, make it an important clinical goal to avoid such treatments. Emerging data are necessary to support alternative treatments for discogenic LBP. This prospective, randomized crossover study was conducted to compare the safety and effectiveness of physician-prescribed conventional medical management (CMM, n 1⁄4 34), including pharmacological management, physical therapy, interventional options, and/or lifestyle changes, to CMM + intradiscal biacuplasty (CMM+IDB, n 1⁄4 29), a minimally invasive technique that utilizes cooled radiofrequency to ablate nociceptive ingrowth, the hallmark of internal disc disruption leading to discogenic LBP. Design: Prospective randomized crossover. Setting: Academic and private practice. Participants: 63 subjects Interventions: Intradiscal Biacuplasty + Conventional Medical Management versus Conventional Medical Management Alone. Main Outcome Measures: The visual analog scale (VAS), SF36-physical functioning (SF36-PF), Oswestry Disability Index (ODI), Beck’s Depression Inventory (BDI), patients’ global impression of change (PGIC), and health-related quality of life (EQ-5D VAS). Results or Clinical Course: Study cohort demographics were wellmatched, and body mass indices were equivalent (26). Baseline scores for each study outcome were similar between study groups. In the CMM+IDB group, no major complications occurred, the mean VAS score reduction exceeded that in the CMM group (-2.4 vs. -0.56; p 1⁄4 .02), and the proportion of treatment responders (2-point or 30% decrease in the VAS) was substantially bigger (50% vs. 18%). Large differences in mean SF36-PF, ODI, and PGIC score changes (p < .05/ outcome) favored CMM+IDB, and changes in the BDI and EQ-5D VAS scores showed greater trends of improved health in the CMM+IDB group. Differences in opioid use between groups were not statistically significant. Conclusion: The comparatively superior outcomes in the CMM+IDB group suggest that IDB is a more effective treatment for discogenic LBP than CMM.
