Validity of Tools to Measure Physical Activity in Older Adults Following Total Knee Arthroplasty.

abstract：:Numerous methods for studying the prevention of falls and age-related sensorimotor degradation have been proposed and tested. Some approaches are too impractical to use with seniors or too expensive for practitioners. Practitioners desire a simple, reliable technique. The goals of this research were to develop such an...
