To evaluate the effectiveness of a functional thumb orthosis on the dominant hand of patients with rheumatoid arthritis and boutonniere thumb.
Forty patients with rheumatoid arthritis and boutonniere deformity of the thumb were randomly distributed into two groups. The intervention group used the orthosis daily and the control group used the orthosis only during the evaluation. Participants were evaluated at baseline as well as after 45 and 90 days. Assessments were preformed using the O'Connor Dexterity Test, Jamar dynamometer, pinch gauge, goniometry and the Health Assessment Questionnaire. A visual analogue scale was used to assess thumb pain in the metacarpophalangeal joint.
Patients in the intervention group experienced a statistically significant reduction in pain. The thumb orthosis did not disrupt grip and pinch strength, function, Health Assessment Questionnaire score or dexterity in either group.
The use of thumb orthosis for type I and type II boutonniere deformities was effective in relieving pain.
评估一种功能性拇指矫形器对类风湿关节炎和纽扣指患者优势手的疗效。
40例患有类风湿关节炎且拇指呈纽扣指畸形的患者被随机分为两组。干预组每天使用该矫形器，对照组仅在评估期间使用。在基线期以及45天和90天后对参与者进行评估。使用奥康纳灵巧性测试、贾马尔握力计、捏力计、测角法和健康评估问卷进行评估。使用视觉模拟量表评估掌指关节处的拇指疼痛。
干预组患者的疼痛在统计学上有显著减轻。拇指矫形器在两组中均未影响握力、捏力、功能、健康评估问卷得分或灵巧性。
使用拇指矫形器治疗I型和II型纽扣指畸形可有效缓解疼痛。
