Elastic bandages are often used to treat musculoskeletal disorders, even though there is little scientific evidence currently to support this generalized practice. We tested the hypothesis that elastic bandages improve proprioception of the bandaged joint during their use, and that this benefit was more than temporary. The uninjured human knee was used as a model. Fifty-four volunteers (54 knees), aged 22 to 40 years, were asked to identify a prior set joint angle as their knee was passively extended. Each knee was tested without the elastic bandage, immediately after bandage application, after 1 hour of bandage wear, and finally after removal of the bandage. Results showed that elastic bandages significantly improved knee joint proprioception in the uninjured knee during the entire interval of their use (mean decrease in inaccuracy of 1.0 degree, equivalent to 25% improvement, P < 0.05), and that this benefit was lost when the bandage was removed. The magnitude of the improvement, or the potential beneficial effect of the bandage, was inversely related to the participant's inherent knee proprioceptive ability, which was demonstrated in the test group before the initial application of the bandage.
弹力绷带常被用于治疗肌肉骨骼疾病，尽管目前几乎没有科学证据支持这种普遍做法。我们检验了以下假设：弹力绷带在使用过程中能改善被包扎关节的本体感觉，且这种益处并非只是暂时的。以未受伤的人体膝关节作为模型。招募了54名年龄在22至40岁之间的志愿者（54个膝关节），要求他们在膝关节被动伸展时识别之前设定的关节角度。每个膝关节在未使用弹力绷带时、刚包扎后、佩戴绷带1小时后以及最后去除绷带后进行测试。结果显示，在整个使用期间，弹力绷带显著改善了未受伤膝关节的本体感觉（不准确程度平均降低1.0度，相当于改善了25%，P < 0.05），并且去除绷带后这种益处消失。改善的程度，即绷带的潜在有益效果，与参与者固有的膝关节本体感觉能力呈负相关，这在绷带初次使用前的测试组中得到了证明。
