title: Ergonomic design of a computer mouse for clients with wrist splints.
abstract: OBJECTIVE
  We explored effects of cutaneous feedback and hump position on efficiency and comfort in mouse use with a splint. We also analyzed the relationship between anthropometric measurements (width of hand and length of hand, palm, and index) and the task performance.
  
  
  METHODS
  Thirty participants performed a computer task with two forms of mice (front hump and rear hump) and two kinds of wrist splints (dorsal and volar). Movement time and satisfaction scores were recorded.
  
  
  RESULTS
  No interaction effect (Hump Position × Splint Type) was found on movement time. Movement time was shorter for rear-hump mouse users than for front-hump mouse users. Movement time was also shorter for wearers of dorsal wrist splints than for wearers of volar wrist splints. Limited differences existed in the satisfaction scores. Participants with a longer index finger had shorter movement time.
  
  
  CONCLUSIONS
  Both dorsal wrist splints and rear-hump mice are recommended. Length of index finger positively correlated with task performance.
