The purpose of this study is to evaluate the effectiveness of the biofeedback gait training device in improving load bearing over an operated limb, during post-operative gait training therapy. The effectiveness of the device will also be tested in self-training at home.

To evaluate the effectiveness of the biofeedback gait training device as a biofeedback training therapeutic tool in improving body-weight bearing over the affected lower limb, quality of gait, level of ambulation and physical independence during rehabilitation, in patients after orthopedic procedures during gait therapy training, and as a biofeedback device for self-training at home.

Inclusion Criteria:

• Functional limitation prior to the current condition
• Premorbid, ongoing major depression or psychosis
• Multiple/pathological fractures
• Serious early complications
• Terminally ill patients
• Pregnant women
• Participation in current or recent (within 60 days prior to surgery) clinical trial
