Hand strength is a key component in human hand function, especially to
those with strength-required jobs. To evaluate post-injury hand strength, this
study was conducted to assess the predictability of hand injury severity scoring
(HISS) system to hand strength after a period of recovery. In this
retrospective study, 80 traumatic hand-injured subjects were recruited. Hand
strength tests measured by dynamometers were performed by subjects in ways of
palmar pinch, lateral pinch and cylindrical grip. The logistic regression models
were used to evaluate the risk of poor hand strength among the severities
represented by HISS scores. RESULTS: A positive correlation exists between the
differences of the strength of two hands, and the severity shown by HISS system
in the poorer half of subjects. The risk to be in poorer half of palmar pinch
subtest is significant in moderate subgroup of HISS severity. The risk to be in
poorer half of cylindrical grip subtest is significant in major subgroup of HISS
severity. The risk to be in poorer half of palmar pinch and cylindrical grip
subtests is significant in skeletal component of HISS system. CONCLUSIONS: HISS
is a descriptive severity scoring system to hand injury and also a useful
instrument to predict functional outcome. This study revealed the HISS system may
predict post-injury hand strength after recovery.
