Abstract:

Data defining electrical waveforms for physical therapy is created on a computer and stored in a removable machine-readable medium such as a CD-ROM or semiconductor memory module. The data is played back, for example on a portable CD-ROM player, to produce the physical therapy waveforms at any time and location convenient or desired by the patient. An interface circuit amplifies and conditions the resulting waveforms for applying them to the skin of the patient via leads and electrodes. Since most therapies use waveforms within the audio frequency range, ubiquitous low-cost audio playback equipment can be used. Advantages of the invention are providing physical therapy at any location and at low cost, without requiring presence of a clinician or other health care professional on location.
