Abstract
ABSTRACT Introduction This study evaluated the efficacy of two different medial linkage mechanisms (sliding mechanism [SM] and medial linkage mechanism associated with reciprocating gait motion (MLRGM), used within otherwise identical knee-ankle-foot orthoses (KAFOs) on patients with spinal cord injury (SCI). Methods Three volunteer subjects with SCI were fitted with a KAFO equipped with 1) an SM and 2) a medial linkage mechanism (MLRGM). Subjects walked at their self-selected speed along a flat walkway to enable a comparison of walking speed, endurance, and the resulting physiological cost index to be performed. Results The use of a KAFO fitted with the MLRGM resulted in improvements in walking speed, distance walked, and energy costs when compared with the more standard SM. However, the time required to don the KAFO increased with use of the MLRGM, but doffing time was approximately equal for both types. Conclusions This study demonstrated that the use of a KAFO with an MLRGM could provide significant benefits for patients with SCI when compared with a KAFO with a standard SM.
期刊介绍:
Published quarterly by the AAOP, JPO: Journal of Prosthetics and Orthotics provides information on new devices, fitting and fabrication techniques, and patient management experiences. The focus is on prosthetics and orthotics, with timely reports from related fields such as orthopaedic research, occupational therapy, physical therapy, orthopaedic surgery, amputation surgery, physical medicine, biomedical engineering, psychology, ethics, and gait analysis. Each issue contains research-based articles reviewed and approved by a highly qualified editorial board and an Academy self-study quiz offering two PCE''s.
