This report compares wrist supination and pronation and flexion and extension
movements with the common body-powered prosthesis and a new biomechatronics
prosthesis with regard to patient satisfaction and problems experienced with the
prosthesis. Fifteen subjects with traumatic transradial amputation who used both
prosthetic systems participated in this study. Each subject completed two
questionnaires to evaluate their satisfaction and problems experienced with the
two prosthetic systems. Satisfaction and problems with the prosthetic's wrist
movements were analyzed in terms of the following: supination and pronation;
flexion and extension; appearance; sweating; wounds; pain; irritation; pistoning;
smell; sound; durability; and the abilities to open a door, hold a cup, and pick
up or place objects. This study revealed that the respondents were more satisfied
with the biomechatronics wrist prosthesis with regard to supination and
pronation, flexion and extension, pain, and the ability to open a door. However,
satisfaction with the prosthesis showed no significant differences in terms of
sweating, wounds, irritation, pistoning, smell, sound, and durability. The
abilities to hold a cup and pick up or place an object were significantly better
with the body-powered prosthesis. The results of the survey suggest that
satisfaction and problems with wrist movements in persons with transradial
amputation can be improved with a biomechatronics wrist prosthesis compared with
the common body-powered prosthesis.
