The WISH-type S-form hip brace (WISH brace) has been shown to significantly improve hip function, functional mobility, and gait biomechanics in patients with hip osteoarthritis. The aim of the current study was to evaluate the effects of the WISH brace over time on the strength of muscles around the hip and knee joints.
A prospective short-term longitudinal study with a 6-month follow-up was conducted. Muscle strengths were measured using a handheld dynamometer.
The muscle strengths of hip flexion, hip abduction, and knee extension were lower in the affected limb than in the unaffected limb, whereas hip adduction muscle strength was reduced to the same extent in both the affected and unaffected limbs. This short-term longitudinal study revealed that only hip adduction and knee extension exhibited significant interaction between legs and time when measurement was performed without the WISH brace. Furthermore, the inherent hip abduction muscle strength of the affected limb was improved by the WISH brace so that the strength became the same as the unaffected limb.
Improvement in abduction muscle strength of the affected limb by daily walking exercise with the WISH brace, which occurred with little interaction with the unaffected limb, may improve hip function.
已证明WISH型S形髋部支具（WISH支具）能显著改善髋骨关节炎患者的髋关节功能、功能活动能力和步态生物力学。本研究的目的是评估WISH支具随时间推移对髋关节和膝关节周围肌肉力量的影响。
进行了一项为期6个月随访的前瞻性短期纵向研究。使用手持测力计测量肌肉力量。
患侧肢体的髋关节屈曲、髋关节外展和膝关节伸展的肌肉力量低于未受影响的肢体，而患侧和未受影响肢体的髋关节内收肌肉力量下降程度相同。这项短期纵向研究表明，在不使用WISH支具进行测量时，只有髋关节内收和膝关节伸展在双腿和时间之间表现出显著的相互作用。此外，WISH支具改善了患侧肢体固有的髋关节外展肌肉力量，使其力量与未受影响的肢体相同。
佩戴WISH支具进行日常步行锻炼可改善患侧肢体的外展肌肉力量，且与未受影响的肢体几乎没有相互作用，这可能会改善髋关节功能。
