The purpose of this study was to investigate static and dynamic balance tests in single, dual cognitive, and dual manual task conditions in participants with and without nonspecific chronic low back pain.
In this case control study, 40 patients (age range 18-50 years) with nonspecific chronic low back pain for at least 3 months and 40 healthy participants matched for age, weight, height, and sex participated in this study. Balance performance was evaluated using static (One Leg Stance) and dynamic (Modified Star Excursion Balance Test, 10-m walk test, and Timed Up and Go) balance tests. All tests were performed in three conditions: single task (balance only), dual cognitive task (balance and counting numbers backward), and dual manual task (balance and carrying a cup of water).
The results indicated that different balance tests were impaired in dual task conditions compared with single task in each group. Cognitive and balance performances were not significantly different between nonspecific chronic low back pain and healthy participants in all clinical balance tests.
It seems that the static and dynamic balance performance under dual task conditions (excluding the Modified Star Excursion Balance Test) was impaired in each group. Dual tasking did not differ between nonspecific chronic low back pain participants with low level of pain and disability compared with healthy participants.
本研究旨在调查有无非特异性慢性下腰痛的参与者在单任务、双重认知任务和双重手动任务条件下的静态和动态平衡测试情况。
在这项病例对照研究中,40名患有非特异性慢性下腰痛至少3个月的患者(年龄范围18 - 50岁)和40名年龄、体重、身高及性别相匹配的健康参与者参与了本研究。使用静态(单腿站立)和动态(改良星标偏移平衡测试、10米步行测试以及定时起立行走测试)平衡测试来评估平衡能力。所有测试均在三种条件下进行:单任务(仅平衡)、双重认知任务(平衡并倒着数数)以及双重手动任务(平衡并端着一杯水)。
结果表明,与单任务条件相比,每组在双重任务条件下不同的平衡测试均受到损害。在所有临床平衡测试中,非特异性慢性下腰痛患者和健康参与者的认知及平衡表现无显著差异。
似乎每组在双重任务条件下(不包括改良星标偏移平衡测试)的静态和动态平衡表现均受到损害。与健康参与者相比,疼痛和残疾程度较低的非特异性慢性下腰痛参与者在双重任务方面没有差异。
