The relationship of metatarsalgia and toe function is poorly understood. We investigated the efficacy of toe exercises for the treatment of metatarsalgia.
Forty-one (56 feet) metatarsalgia patients (mean age ± SD: 63.4 ± 10.6) underwent toe strength measurement. We recorded pre- and post-treatment VAS score, AOFAS score, marble pickup, single-leg standing time (SLST), and compared in two subgroups to evaluate impact of disease duration on treatment outcome.
Post treatment, toe plantarflexion strength improved (all p < 0.01); VAS scores decreased (p < 0.01); AOFAS scores, marble pickup, and SLST improved (all p < 0.01). Patients symptomatic for > 1 year had significantly lower changes in VAS scores (p < 0.01). Multivariate analysis showed patients with longer disease duration, and larger body mass index had significantly lower improvement in VAS scores (p = 0.029 and p = 0.036, respectively). Device consistency assessed by ICC was excellent (0.89-0.97).
Toe function and metatarsalgia are improved by toe exercises, suggesting that they are closely related.
跖痛症与脚趾功能之间的关系尚不清楚。我们研究了脚趾运动治疗跖痛症的疗效。
41 例（56 只脚）跖痛症患者（平均年龄±标准差：63.4±10.6 岁）进行了脚趾力量测量。我们记录了治疗前后的 VAS 评分、AOFAS 评分、拾丸测试、单腿站立时间（SLST），并在两个亚组中进行比较，以评估疾病持续时间对治疗结果的影响。
治疗后，脚趾跖屈力量提高（均 P<0.01）；VAS 评分降低（P<0.01）；AOFAS 评分、拾丸测试和 SLST 提高（均 P<0.01）。症状持续时间>1 年的患者 VAS 评分的变化明显较低（P<0.01）。多变量分析显示，疾病持续时间较长和体重指数较大的患者 VAS 评分的改善明显较低（P=0.029 和 P=0.036）。ICC 评估的设备一致性为优秀（0.89-0.97）。
脚趾运动可改善脚趾功能和跖痛症，提示两者密切相关。
