title: [The biofeedback sole tested is a suitable device for avoiding overload under partial load].
abstract: During healing of fractures and after implantation of artificial joints mobilization with partial load is a widespread and well-accepted therapeutic principle. Translating our recommendations into action, however, overtaxes many of the patients. The use of the biofeedback sole tested should guarantee avoiding overload under partial weight-bearing conditions. The distribution of the strain sensors in the biofeedback sole was primarily checked with the help of an established system controlling the distribution of strain (PAROTEC) in 17 voluntary, healthy people. Afterwards the biofeedback sole was connected to a digital recording system to analyze the number of steps overloaded in different test cycles in 50 volunteers while using crutches and performing partial load with 20 kg. The distribution of the strain sensors in the biofeedback sole is correct to control partial load under weight bearing with 20 kg. The permanent use of the biofeedback sole showed highly significant advantages in avoiding overload. The number of steps overloaded was reduced by 77%. This effect is independent from body weight or age.
