A system and related method for characterizing an effect of a rehabilitation therapy on a body. The apparatus includes a first device, which is configured to be coupled to the body at a first location, and a second device, which is configured to be coupled to the body at a second location that is separated from the first location by a distance. The first device is configured to generate a wireless signal. The second device is configured to detect the wireless signal and to generate data based on the detected wireless signal that is configured to be used to calculate the distance. The distance is used to characterize the effect of the rehabilitation therapy on the body. |
