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.

Title of diploma's thesis: The effectiveness of program in lower limbs injuries in handball Abstract: The theoretical part of diploma's thesis contains detailed description of anatomy and kinesiology of knee and ankle joints. It also link injuries which affect this parts of body. This part contains accident occurrence in sports, causes and mechanism of injury. We could not forget the theoretical treatment for the prevention of injury. The practical part is the creation and application of a simple prevention motion program that will have a preventive effect in terms of lower limb injuries of female handball players. Research thesis therefore dealt efficiency of our original motion program. We checked the statistically processed data on the number and type of injuries in female players of handball in the first league of women. The effectiveness of our motion program was confirmed by reducing the number of injuries of the lower limbs in the intervention group. Key words: lower limb injury, injury prevention, accident occurrence, special prevention motion program
