Abstract: A device for monitoring a treatment of posture of body parts in which a local mechanotherapeutic stimulus is applied includes an elastic material which is to be worn over the part of the body, a pressure regulating support, a pressure applicator and a pressure sensor. The support is fixed to the elastic material and passes over a region where mechanotherapeutic stimulus is to be applied. The sensor is rigidly attached to the pressure applicator and they are together received in a pocket. The sensor senses pressure and hence a stimulus applied to the part as a result of the tension in the support, the sensor being configured to output a signal indicative of the pressure applied, providing the opportunity to change the stimulus to within a given range based on the feedback from the sensor. A method for using the device is also disclosed.
