Each of the range of motion measures was also
rated for associated pain on the same scale. In addition, knee flexion
was measured in both a standing and supine position by a 14-inch
double-armed goniometer along with any associated pain. An
adaptation of The Short Physical Performance Battery (SPPB) [10]
was also given. This adapted battery consists of sitting and standing
up from a chair ROM and pain, balance (standing on one leg)
and a timed 8 foot walk and associated pain.
