title: Using the Nintendo Wii Fit and body weight support to improve aerobic capacity, balance, gait ability, and fear of falling: two case reports.
abstract: OBJECTIVE
  Lower limb amputation in older adults has a significant impact on balance, gait, and cardiovascular fitness, resulting in diminished community participation. The purpose of this case study was to describe the effects of a balance training program utilizing the Nintendo Wii™ Fit (Nintendo of America, Inc, Redmond, Washington) balance board and body-weight supported gait training on aerobic capacity, balance, gait, and fear of falling in two persons with transfemoral amputation.
  
  
  METHODS
  Participant A, a 62 year-old male 32 months post traumatic transfemoral amputation, reported fear of falling and restrictions in community activity. Participant B, a 58 year-old male 9 years post transfemoral amputation, reported limited energy and balance deficits during advanced gait activities.
  
  
  METHODS
  6-weeks, 2 supervised sessions per week included 20 minutes of Nintendo™ Wii Fit Balance gaming and 20 minutes of gait training using Body Weight Support.
  
  
  RESULTS
  Measures included oxygen uptake efficiency slope (OUES), economy of movement, dynamic balance (Biodex platform system), Activities-Specific Balance Confidence (ABC) Scale, and spatial-temporal parameters of gait (GAITRite). Both participants demonstrated improvement in dynamic balance, balance confidence, economy of movement, and spatial-temporal parameters of gait. Participant A reduced the need for an assistive device during community ambulation. Participant B improved his aerobic capacity, indicated by an increase in OUES.
  
  
  CONCLUSIONS
  This case study illustrated that the use of Nintendo Wii™ Fit training and Body Weight Support were effective interventions to achieve functional goals for improving balance confidence, reducing use of assistive devices, and increasing energy efficiency when ambulating with a transfemoral prosthesis.
