Objective To investigate the immediate effects of bilateral upper‐extremity sanding exercises on conduction and morphologic characteristics median ulnar nerves at wrist in hemiparetic subjects control subjects. Design Case study using a pretest–post‐test design. Setting Inpatient rehabilitation department affiliated with teaching hospital. Patients (or Participants) Thirty 21 matched who met our inclusion criteria had no history diseases that may have predisposed them to peripheral neuropathies were recruited for this study. Methods Bilateral nerve tests ultrasonographic evaluations performed each subject before immediately after 30‐minute exercise frequency 5 repetitions per minute. Main Outcome Measurements The assessed use sensory motor velocity by width/thickness ratios evaluations. Results In hemiparesis group, pre‐exercise amplitude component respectively lower than corresponding values group ( P < .05), whereas .01). After exercise, assessments affected side showed reductions an increase ratio .05). Conclusions different compared Their also demonstrated significant changes exercises. These subclinical findings be attributed mechanisms such as overuse, spasticity, demyelinating changes. Prevention these is recommended enhance safety patients.
