Limb amputations and prosthetics

Prosthetics / Amputations

The technique of hydrogen clearance has been used in five canines to monitor blood flow in gastrocnemius muscle following sympathectomy. The contralateral nonsympathectomized limb was used as a control . Average blood flow was based on 22 pairs of desaturation data . Average blood flow in the left control limb was 6.08 ± 2 .22 ml/min/100g tissue and the right sympathectomized limb was 9.54 ± 3 ...

Upper extremity amputations and prosthetics.

Upper extremity amputations are most frequently indicated by severe traumatic injuries. The location of the injury will determine the level of amputation. Preservation of extremity length is often a goal. The amputation site will have important implications on the functional status of the patient and options for prosthetic reconstruction. Advances in amputation techniques and prosthetic reconst...

Limb prosthetics-1970.

Locomotion and lower-limb prosthetics.

One of the principal activities of the members of the Biomechanics Laboratory during the past two decades has been the study of human locomotion . A major objective of these studies has been the accumulation of data that might be used in the design and construction of improved prosthetic and orthotic devices . The investigations have included electromyograms of the phasic action of muscles, for...

Progressive upper limb prosthetics.

The field of upper extremity prosthetics is a constantly changing arena as researchers and prosthetists strive to bridge the gap between prosthetic reality and upper limb physiology. With the further development of implantable neurologic sensing devices and targeted muscle innervation (discussed elsewhere in this issue), the challenge of limited input to control vast outputs promises to become ...
