Collateral Ligament Reconstruction Rehabilition Protocol

The identification of osseoperception as a phenomenon of osseointegration was the result of work carried out in the dental sciences by Torgny Haraldson In 1979 he characterized the sensory feedback in patients with osseointegrated bridges and concluded, “Patients with osseointegrated bridges have been restored to a level of functional capacity of the masticatory system equal to that in individuals with a natural but reduced dentition of the same extension as in the osseointegration group.” Osseoperception has also been studied in orthopaedic applications. Experimentally, vibratory perception around implants in the femoral, tibial, ulnar, radial, and (meta)carpal bones has been assessed by means of the psychophysical threshold determination of passive stimuli applied to the implants, whereby the subject has to answer whether he/she detects the stimulus or not. Experiments were carried out on two groups of patients who had suffered limb amputation .Group 1 consisted of amputees who had been rehabilitated by means of prostheses supported by osseointegrated implants. Group 2 consisted of amputees wearing conventional socket prostheses. For each subject in Group 1, a subject of the same gender with a comparable age and amputation level was selected to participate in Group 2. Vibratory threshold determination was carried out on the control limb and the prosthetic limb of all amputees. For transfemoral or transtibial amputees, the great toe (I) and the little toe (V), or the metatarsal, were tested. For transhumeral or transradial amputees, the thumb, the index finger (II), and the little finger (V) were tested. This method was also applied for threshold determination of the stump of amputees in Group 2 to compare these values to implantstimulation threshold
