Subsequent to a difficult surgery or a sever injury to the lower part of the body, often partial load bearing is needed to stimulate an optimal rehabilitation. Today, this is achieved by teaching the patient the optimal load by iteration. This has been shown insufficient for many patients, due to their difficulties of remembering the correct amount of load. Furthermore, patients who lack proprioception are unable to feel the load. A portable measuring system would enhance the patient possibility of optimal loadings. This thesis has two main objects. 1. A study of the state of the art on existing commercial system, related patents and measuring techniques. 2. A new measuring technique, which is the part that most of all determine the system performance, was developed. A new design, using off the shelf, products is proposed. The design uses a finite number of thin sensors placed onto an insole. By placing the sensors at the plantar pressure points most of the total load is captured by the insole setups. To compensate for the measuring error fitting methods were evaluated. The result depends on the insole calibration methods. The best result without individual calibration is: mean error for the group of 0.5% of the total patient load and a deviation of 24%. With individual calibration reduces the deviation to about 12%.
