Abstract: Innervation and tension of the forearm muscles are of central interest in the pathogenesis of epicondylitis. Heat leads to relaxation and improvement of muscle coordination.The aim of this study was to investigate the heat effect an the innervation of the forearm muscles in tennis elbow. Six forearm muscles of 30 patients with epicondylitis were analysed by EMG under defined load application. Heat was applied by an infrared lamp for 5 minutes. The average height of the EMG-amplitudes increased directly after exposure to heat. It is suggested that the active number of muscle fibres increases as a result of the application. It seems likely that heat reduced pain reactivates inactive motor muscle units.
