The functional performance of currently available body-powered
prostheses is unknown. OBJECTIVE: The goal of this study was to objectively
assess and compare the functional performance of three commonly used body-powered
upper limb terminal devices. STUDY DESIGN: Experimental trial. METHODS: A total
of 21 able-bodied subjects
(n = 21, age = 22 +/- 2) tested three different
terminal devices: TRS voluntary closing Hook Grip 2S, Otto Bock voluntary opening
hand and Hosmer Model 5XA hook, using a prosthesis simulator. All subjects used
each terminal device nine times in two functional tests: the Nine-Hole Peg Test
and the Box and Blocks Test. RESULTS: Significant differences were found between
the different terminal devices and their scores on the Nine-Hole Peg Test and the
Box and Blocks Test. The Hosmer hook scored best in both tests. The TRS Hook Grip
2S scored second best. The Otto Bock hand showed the lowest scores. CONCLUSION:
This study is a first step in the comparison of functional performances of
body-powered prostheses. The data can be used as a reference value, to assess the
performance of a terminal device or an amputee. CLINICAL RELEVANCE: The measured
scores enable the comparison of the performance of a prosthesis user and his or
her terminal device relative to standard scores.
