Amputee locomotion: Lower extremity loading using running-specific prostheses

Step frequency and lower extremity loading during running.

The purpose of the present study was to ascertain whether increase in step frequency at a given velocity during running reduces the lower extremity loading variables, which is associated with tibial stress fracture in runner. We hypothesized that the lower extremity loading variables at a given speed would be minimized at around +15% f step. 10 male subjects were asked to run at 2.5 m/s on a tr...

Componentry for Lower Extremity Prostheses

Prosthetic components for both transtibial and transfemoral amputations are available for patients of every level of ambulation. Most current suspension systems, knees, foot/ankle assemblies, and shock absorbers use endoskeletal construction that emphasizes total contact and weight distribution between bony structures and soft tissues. Different components offer varying benefits to energy expen...

Stump Bandaging of the Lower-extremity Amputee.

In many rehabilitation centers and hospitals throughout the country, the physical therapist must wait for the amputee to be referred for treat­ ment. Often the surgeon will not refer the elderly patient or the one suffer­ ing with a vascular impairment until the sutures are removed and healing is complete. Early referral of the young, traumatic amputee for proper preprosthetic treatment is well...

Endoskeletal structures for lower-extremity prostheses.

Historical development of lower-extremity prostheses.

In studying the history of the construction of artificial limbs to sub­ stitute for lost legs, which has been transmitted to us by written words, objects of art and handicraft, objects found in excavations, and so forth, and learning of the development of the artificial leg through the centuries, one gains knowledge of the foundation on which modern prosthetics is based. Such an historical revi...
