PURPOSE: To develop and clinically evaluate a novel assistive walking system, the
Wearable Power-Assist Locomotor (WPAL). METHODS: To evaluate the performance of
WPAL, a clinical trial is conducted with four paraplegic patients. After fitting
the WPAL, patients learned to use the WPAL. The length and duration of
independent walking was measured and compared to conventional orthosis
(Primewalk). RESULTS: After training, all patients were able to stand, sit, and
walk independently with the WPAL. Compared to a conventional orthosis
(Primewalk), the duration and distance of independent ambulation increased. The
physiological cost index (PCI), perceived exertion and EMG of upper extremities
decreased. CONCLUSIONS: WPAL might greatly enhance the possibility of restoration
gait to paraplegic patients.
