The purpose of this study was to determine the effectiveness of the Augmented Soft Tissue Mobilization (A.S.T.M.) Rehabilitation Technique on total knee replacement patients. The specific measurements assessed were stride length (SL), stride frequency (SF), walking velocity, support time (ST), total time (TT), static and walking range of motion (ROM) of the hip, knee, and ankle, ground reaction forces (GRF), and torques. Fourteen subjects (Female = 7, Male = 7) completed the study. Subjects were randomly assigned to two experimental groups, the Traditional Therapy treatment or the A.S.T.M. treatment. There were five testing sessions: pre operation, 8 weeks, 12 weeks, 16 weeks, and 24 weeks post operation. On the 12 week test, the subject had completed their assigned of treatment protocol. Static ROM was derived from gonimetric measurements before each testing session. Stride length, stride frequency, velocity, time, and walking ROM were derived from accelerometer data. Statistical analysis using ANOVA revealed a significant change in all static ROM, SL, and ST. The data indicated that both groups of the Total Knee Replacement patients did improve their functional status from their status prior to surgery. In addition, the data indicated that the Augmented Soft Tissue Mobilization program and the Traditional Therapy program are equally acceptable rehabilitation techniques.
