Abstract
Background: Studies collectively imply that the reciprocal link has no effect on walking when using reciprocating gait orthoses (RGOs). There may be differences between the 2 configurations of the RGO (eg, isocentric reciprocating gait orthosis [IRGO] and IRGO without reciprocating link), but the specific benefits and problems encountered in their use must be understood. Purpose: To highlight more evidence for the mechanical function of the reciprocal link in RGOs used for walking by individuals with spinal cord injury (SCI). Methods: Nine people with SCI participated in this study. Gait analysis was performed in 2 conditions (walking with IRGO and walking with IRGO without reciprocating link) in a random order. The Vicon digital capture system was used to obtain kinematic data. Results: There were significant differences between each orthotic configuration in terms of speed of walking (p = .029), step length (p = .048), hip joint range of motion (ROM) (p ≤ .001), and lateral and vertical compensatory motions (p ≤ .001). There was no significant difference between each orthotic configuration in cadence (p = .162). Conclusion: The reciprocating link in IRGO improved the walking parameters in SCI patients.
