The relationship of technology assessment and utilization. Electromyographic feedback instrumentation as a model

Biofeedback instrumentation has been a growing part of physical therapy practice for 20 years, and physical therapists have contributed to researching its efficacy in treating varying conditions. The application of biofeedback to the treatment of stroke was marked by some early difficulties with the quality of the electronics, but sophisticated contemporary equipment can do much more than was originally envisioned. The importance of relating quantified movement-based data to functional measures is projected as a high priority if appropriate reimbursement for physical therapy services with biofeedback is to continue in the future.
