RESUMO
This study was designed to evaluate the efficacy of calcium gluconate iontophoresis in patients with writer's cramp. Fifteen patients [with ages range from 22 to 31 years] were randomly assigned into two groups [control and study; 7 and 8 respectively]. Electromyographic activity was recorded from flexor carpi ulnaris muscle before and after treatment. Also, hand dexterity was assessed via Purdue Pegboard Test. Both groups received physical therapy program. In addition, the study group received iontophoresis with calcium gluconate for 20 minutes and the control group received placebo iontophoresis. Treatment program was given for 12 sessions every other day. The results revealed significant decrease in the electromyographic activity of the flexor carpi ulnaris muscle in the study group [p=0.0001] and significant improvement in the hand dexterity and manipulative skills [p=0.03]. Calcium gluconate iontophoresis was effective in improving hand functions in writer's cramp
