Motor performance with a simulated artificial limb.

The present study was conducted to examine performance differences on a reaching and grasping task related to an activity of daily living. This involved either the anatomical limb or a simulated artificial limb. College-aged volunteers (2 men and 4 women), one of whom was left-handed, performed the reaching and grasping task. The apparatus, placed on a table before the seated participant, was a square wooden board which contained a starting key and holes for the insertion and removal of a small Fiberglas dowel. At the beginning of the trial the participant depressed the start key, reached forward and grasped the dowel, and then returned the dowel to a finishing hole located directly in front of the start key. The results of 2 (side) x 2 (type of limb) repeated-measures multivariate analyses of variance on the mean and standard deviation of the movement times showed a significant main effect for type of limb (Wilks lambda 3,3 = .047 and .079, respectively, p < .05). Analyses of variance on mean total transport time, extension time, flexion time, and their standard deviations showed that times were slower and less consistent with the prosthesis for all measures. These results and those of later research should be focused on the development of training principles for both therapists and individuals with an amputation. In addition, the simulated prosthesis is an excellent experimental model for basic and clinical research in the control and acquisition of coordinated movement.

Bilateral below-knee amputee 107 years old and still wearing artificial limbs.

It is not often that a person over 100 years old is able to walk on artificial limbs and maintain their mobility and independence after going through bilateral below-knee amputation. This case note is about a 107 year old lady with bilateral below-knee amputation, who is perhaps the oldest surviving bilateral below-knee amputee in the British Isles, if not in the World. There does not appear to be any reference in the literature to a bilateral below-knee amputee of 100 years old plus, who is still alive and wearing his or her artificial limbs. The nearest is of a 91 year old lady with bilateral below-knee amputation and wearing artificial limbs, reported by Gerhardt et al, 1986.

Do artificial limbs become part of the user? New evidence.

This paper provides evidence that limb-deficient subjects who wear artificial arms tend to overestimate the perceived length of their residual limb. It is proposed that this "perceptual error" may provide a useful and possibly more valid alternative to existing methods of determining prosthetic acceptance. The degree of overestimation is substantial for most subjects with amputations, and typically represents 20 percent of the length of the prosthetic arm. The effect is considerably reduced when the prosthetic limb is removed. Comparisons are made with normal-limbed subjects of various ages. For the most part, their errors are small and typically are underestimates of actual limb length. This research is compared with the work of Fraser (1984), who found similarities in reaching trajectories for normal and artificial arms. Further investigation is required to determine if this effect may serve as an index of adjustment to a prosthesis and, additionally, if prosthetics training programs might benefit from including techniques for enhancing perceptual adaptations to artificial limbs.

Silicone suspension of external prostheses. A new era in artificial limb usage.

The use of silicone inner sockets, with or without the incorporation of shuttle locks, has greatly improved the function of artificial limbs. They cushion and protect the stump and provide a means for prosthetic suspension, allowing more comfortable use, especially in patients with ischaemic stumps. They also allow greater movement at the proximal joint.
