Proprioception in Above-the-Knee Amputees with Artificial Limbs
نویسندگان
چکیده
PURPOSE To evaluate the lower limb proprioceptive sensation in patients with femoral amputation who received an artificial joint. MATERIALS AND METHODS 22 patients (18 men, 4 women), 24-65 years old (mean: 42), who had undergone above-the-knee joint amputation and underwent evaluation of proprioception using joint reposition in a predetermined angle of 15° knee flexion. The measurements were applied using a conventional goniometer to both amputated and healthy knees. The last ones were used as internal control. All patients performed an active knee flexion from hyperextension to 15° in a closed kinetic chain in order to evaluate proprioceptive sensation of the knee joint using the joint position sense (JPS) method during specific controllable circumstances very close to normal gait. RESULTS JPS at 15° flexion for the amputated knee was calculated to be equal to 13.91 (SD = ±4.74), and for the healthy side it was equal to 14.15 (SD = ±2.61). No statistically significant differences were detected between the amputated and the healthy limb (P > 0.05). CONCLUSIONS The proprioceptive information of the stumps did not appear to be affected significantly after thigh amputation and application of artificial prosthesis when JPS at 15° was evaluated. It seems that these patients compensate the loss of the knee sensory receptors via alternative mechanisms.

Introduction Lower-extremity amputees, the group with which this paper is concerned, include persons who have been subjected to gross anatomic loss of the lower limbs at widely varying levels, such as partial foot amputation, below-knee and above-knee amputations, knee or hip disarticulation, and hemipelvectomy. Amputation at each level is attended by distinctive problems of functional loss, fi...

The Vacuum Assisted Socket System (VASS), developed by Total Environmental Control (TEC), is a specialized device used with artificial limbs to manage residual limb volume fluctuation in amputees. The system consists of a TEC liner, suspension sleeve and air evacuation pump. The device creates an elevated vacuum between the liner and the socket wall. The elevated vacuum promotes natural fluid e...
