E-mail: rsgladys{at}polyu.edu.hk This study examined the clinical effectiveness of high-frequency transcutaneous electrical nerve stimulation for reducing hypersensitivity of the hand. Nineteen patients suffering from hand hypersensitivity were randomly assigned into either a treatment or a placebo group. A visual analogue scale and the Downey Hand Centre Hand Sensitivity Test were used to measure the tactile tolerance of the hand. Grip strength was assessed by a grip dynamometer. Daily applications of electrical stimulation were provided for 2 weeks. Significantly lower pain scores were found in the treatment group than in the placebo group by Day 7 and Day 11. The ranking of ten dowel textures of the Downey Hand Centre Hand Sensitivity Test in the treatment group was significantly higher than in the placebo group by Day 7 and Day 11. However, no significant intergroup difference was found in grip strength.
