The Continuous Passive Motion Machine (CPMM) is a post-surgical machine which aids in the recovery of the patients in terms of getting back muscle coordination, muscle strength and range of motion. Using CPMM has also shown a clear reduction to hospital stay and recovery time. However, since the inception the CPMM in 1970, there has not been any major change to the design of the machine. Through various researches and hospital visits, the current CPMM models are not able to fulfil the needs put forward by the patients and therapist. One of the biggest shortcomings of current models of CPMM is that the machine does not vary the difficulty of the exercise through analysing physiological feedback provided patient and hence a therapist must be by the side of the patient at all times. Other shortcomings of current models include lack of interaction between machine and patient; machines fail to provide valuable feedback to patient and etc. In this report, we will attempt to redesign CPMM through making 3 chances in the model. First, we will add a feedback gathering device and through programming the prototype will be able to analyse the patient’s effort and vary the difficulty of the exercise. Next we will add an interactive interface that includes a game to engage and provide valuable information to the patient. Lastly, the stand of the CPMM is redesigned so that it provides a variety of exercises for the patient. The resulting prototype is one that is intelligent and provides an interactive exercise and valuable feedback to the patient.
