Objective To evaluate the ultrasonographic findings obtained following various degrees of elbow flexion in patients with cubital tunnel syndrome (CuTS). Design Retrospective, cross-sectional study. Setting General teaching hospital, rehabilitation unit. Subjects Electrophysiological and ultrasonographic assessments were performed on 11 elbows of healthy controls and 21 elbows of 17 patients with CuTS. Methods Dynamic movement of the ulnar nerve during elbow motion was measured. To measure ulnar nerve dynamic movement during elbow motion, the distance from the medial epicondyle (ME) to the nearest surface of the ulnar nerve toward the ME was measured at the cubital tunnel inlet at elbow extension (0°), elbow flexion to 60°, and elbow flexion to 90°. Results The distance between the ME and ulnar nerve was lower in CuTS patients than in healthy patients at all elbow flexion angles. This difference was statistically significant at 0° and 60° elbow flexion (P  < 0.05). When calculating the cutoff value, the distance between the ME and ulnar nerve at full elbow extension for CuTS diagnosis was 0.53 cm (sensitivity = 71.4%, specificity = 90.7%). The distance ratio between the ME and ulnar nerve for diagnosis of ulnar neuropathy at the elbow was 24.4% (sensitivity = 76.2%, specificity = 100%). Conclusion Measurement of the distance between the ME and ulnar nerve in full elbow extension may facilitate the diagnosis of patients with CuTS. These findings may be important for CuTS diagnosis, as they were also observed in patients with mild-stage CuTS. [ABSTRACT FROM AUTHOR]

The article focuses on the impact of Chiropractic Care on use of prescription opioids in patients with spinal pain. Topics discussed include the Institute of Medicine has recommended the use of nonpharmacological therapies as effective alternatives to pharmacotherapy for patients with chronic musculoskeletal pain; and the pattern of repetitive encounters typical of a course of chiropractic care may account for the sustained benefit.

Spinal and bulbar muscular atrophy, namely Kennedy disease, is a rare progressive neurodegenerative disorder caused by the expansion of a CAG repeat in the first exon of the androgen receptor gene on the X chromosome. We assessed the clinical history, laboratory findings, functional scales and electrophysiological data, as well as the levels of luteinizing hormone, follicle-stimulating hormone and testosterone, in 157 Korean patients with genetically confirmed spinal and bulbar muscular atrophy (mean age at data collection = 56.9 years; range = 33–83 years). Hand tremor was the first symptom noticed by patients at a median age of 35 years, followed by gynaecomastia, orofacial fasciculation, cramps and fatigability in ascending order. Clinical symptoms such as paraesthesia and dysphagia appeared during the later stages of the disease. Cane use during ambulation began at a median age of 62 years. There were statistically significant differences between patients and controls in the results of sensory nerve studies, motor conduction velocity, and distal latencies. Furthermore, among the hormone markers analysed, the level of luteinizing hormone exhibited a negative correlation with the spinal and bulbar muscular atrophy functional rating scale, Korean version. However, among the patients with a disease duration of ≤5 years, the levels of luteinizing hormone showed a significant correlation with assessments using the amyotrophic lateral sclerosis functional rating scale-revised, spinal and bulbar muscular atrophy functional rating scale, Korean version and the 6-minute walk test. In conclusion, our findings provide clinical information from a substantial number of patients with spinal and bulbar muscular atrophy in Korea that accorded with that of patients with this disease worldwide but with updated clinical features.
