Clinical evaluation of a sensory feedback device: the limb load monitor.

Based on records of 81 patients who used the LLM, and on questionnaire answers and comments from clinicians, the following can be concluded: 1. The LLM can be operated easily after a minimum of training. It does not break down with extended clinical use when handled properly. 2. The LLM manual provides sufficient information for proper operation and clinical use of the device. 3. The number of patients in a clinic who can benefit from LLM training can be predicted, if consideration is given to the type of facility and the size of the patient population and physical therapy staff. 4. The largest diagnostic group of patients who can benefit from LLM therapy are lower-limb amputees, followed by hemiplegic and orthopedic patients. 5. The general selection criteria outlined initially proved sufficient. A patient who is selected properly can be expected to respond to the feedback signal (i.e., make a weight-bearing adjustment) within the first or second session.
