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.
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.
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.
手部力量是人手功能的关键组成部分，特别是对于那些需要力量的工作。为了评估手部损伤后的力量，本研究旨在评估手部损伤严重程度评分（HISS）系统在手损伤后一段时间的恢复过程中对手部力量的预测能力。
在这项回顾性研究中，共招募了 80 名手部创伤患者。通过测力计对患者进行手掌捏、侧捏和圆柱握力测试。使用逻辑回归模型来评估 HISS 评分所代表的严重程度与手部力量较差之间的风险关系。
在较差的一半受试者中，手部力量的差异与 HISS 系统显示的严重程度之间存在正相关。在 HISS 严重程度的中度亚组中，手掌捏测试较差的一半的风险显著。在 HISS 严重程度的主要亚组中，圆柱握力测试较差的一半的风险显著。在 HISS 系统的骨骼成分中，手掌捏和圆柱握力测试较差的一半的风险显著。
HISS 是一种手部损伤的描述性严重程度评分系统，也是预测功能结局的有用工具。本研究表明，HISS 系统可能可以预测手部损伤后的手部力量恢复情况。
