The timed walk test is essential for assessing the functional capacity of persons with multiple sclerosis (MS). When a decline in ambulation ability and loss of function in the later stages of MS is observed, it is imperative to utilize alternative methods for measuring functional capacity.
To investigate the validity and reliability of the Six-Minute Pegboard Ring Test (6PBRT) in persons with MS.
Forty-three persons with MS were included in this study. Disease severity was quantified using the Expanded Disability Status Scale (EDSS). The 6PBRT was employed to assess upper extremity function during exercise stress, and vital signs were monitored pre- and post-test. Muscle strength was measured using a digital dynamometer for shoulder flexor, shoulder abductor, and grip strength, in addition to a hand dynamometer. Manual dexterity was evaluated through the 9-Hole Peg Test (9HPT), and walking endurance was assessed using the 2-Minute Walk Test (2MWT). Test-retest reliability was computed using the intraclass correlation coefficient (ICC).
The ICC value for the 6PBRT was 0.96 (95% CI 0.92-0.97), indicating excellent test-retest reliability. Significant differences in vital signs were observed before and after conducting the 6PBRT (p < 0.05). A strong negative correlation was found between the 6PBRT score and EDSS (r = -0.650, p < 0.001). The 9HPT of the dominant side demonstrated a moderate correlation with the 6PBRT score (r = -0.502, p = 0.001), whereas no significant correlation was shown between the non-dominant side 9HPT and the 6PBRT score (p > 0.05). Moreover, a positive moderate correlation was shown between the performance on the 2MWT and the 6PBRT score (r = 0.413, p = 0.006). However, no significant correlation was detected between the proximal muscle strength of the upper extremity, handgrip strength, and the 6PBRT score in individuals with multiple sclerosis (p > 0.05).
The 6PBRT is a reliable and valid tool to evaluate upper extremity function and exercise capacity in persons with MS.
计时步行测试对于评估多发性硬化症（MS）患者的功能能力至关重要。当观察到患者在疾病后期的步行能力下降和功能丧失时，就必须使用替代方法来测量其功能能力。
研究六分钟指套环测试（6PBRT）在多发性硬化症患者中的有效性和可靠性。
本研究纳入了 43 名多发性硬化症患者。采用扩展残疾状况量表（EDSS）评估疾病严重程度。使用 6PBRT 在运动应激下评估上肢功能，并在测试前后监测生命体征。使用数字测力计测量肩部屈肌、肩部外展肌和握力，以及手测力计测量肌肉力量。使用 9 孔插销测试（9HPT）评估手灵活性，使用 2 分钟步行测试（2MWT）评估步行耐力。使用组内相关系数（ICC）计算测试-重测信度。
6PBRT 的 ICC 值为 0.96（95%CI 0.92-0.97），表明具有极好的测试-重测信度。进行 6PBRT 前后生命体征有显著差异（p < 0.05）。6PBRT 评分与 EDSS 呈强烈负相关（r = -0.650，p < 0.001）。优势侧 9HPT 与 6PBRT 评分呈中度相关（r = -0.502，p = 0.001），而非优势侧 9HPT 与 6PBRT 评分无显著相关性（p > 0.05）。此外，2MWT 表现与 6PBRT 评分呈正中度相关（r = 0.413，p = 0.006）。然而，在多发性硬化症患者中，上肢近端肌肉力量、握力与 6PBRT 评分之间无显著相关性（p > 0.05）。
6PBRT 是一种可靠且有效的工具，可用于评估多发性硬化症患者的上肢功能和运动能力。
