Measuring set-up

During the measurements, a power induction coil and a receiver antenna are fixed near the patient’s implant. The implanted telemetry transmitter is powered inductively by the external magnetic field. The signals measured were transmitted to the external device TELEPORT for on-line force display on a notebook screen. The activities of the patient are videotaped, and the data from the implants are recorded simultaneously on the audio tracks of the same cassette.
