Ultrasonographic Evaluation of the Effects of Different Wrist Positions on the Median Nerve in Patients With Generalized Joint Hypermobility

The aim of this study was to evaluate the effects of different wrist positions (neutral, flexion, extension, and ulnar deviation) on median nerve morphology in patients with generalized joint hypermobility (GJH) using ultrasonography and to compare them with healthy controls. The investigators' hypothesis is that the deformability of the median nerve in response to active maximal wrist flexion, extension, or ulnar deviation may be increased in patients with GJH
