Prosthesis are artificial mechanisms intended to replace or improve the functions of missing or handicapped body parts. ( › Medical Encyclopedia). There are many types of leg prosthesis. The leg prosthetics are divided into two groups, being one of them 'below the knee' (transtibial) and the other called 'above the knee' (transfemoral) . We can also mention 'hip disarticulations', a partial amputation of the hip, knee disarticulations which involves amputations concerning the knee, and 'symes' which are ankle disarticulations having the preservation of the heel as objective. There are many types and styles of lower limb prosthesis, each adjusting itself to the nature of the amputation. All of them includes foot and…show more content…
Foot or partial foot prosthesis: This is used to replace the amputated foot. Ankle.part is, optionally, bendable to ensure a better movement. 2. Below-the-knee prosthesis: Mechanism composed by a metal tube (shin) with a socket on top connecting it to the stump while the lower end connects to the artificial ankle and foot. 3. Above-the-knee prosthesis: A complete, yet basic, mechanical leg consisting in a metal tube with a socket on top connecting to the stump with the foot and ankle being connected to the lower part. The knee part is capable of bending in order to maintain a natural pace when…show more content…
Having a prosthesis for more than a decade can be strongly associated with using the intact leg as the preferred leg more often under both free standing and supported conditions. This demonstrates that weaker leg preference in the prosthesis users may provide basis for some inconsistence in motor behavior during different tasks. In regarding the functionality and life’s quality in patients with K2 or K3 prosthesis it is found that K3 foot provides many additional benefits if compared to K2. The relationship between stride length and cadence over slow, normal and fast speeds in below knee prosthesis users denotes that coupling between cadence and step length is unstable in prosthesis users. When comparing stability parameters between limbs, there is discrepancy between intact and prosthetic limbs. Generally, parameter shows that the intact limb is more unstable comparison to the prosthetic limb. This may be caused by the fact that the intact limb has a greater range of mobility and the needed musculature, proprioception, and motor control to compensate for unexpected disruptions in equilibrium while performing locomotive
