ABSTRACT
BACKGROUND: Line dancing is a popular form of exercise shown to affect balance and mood positively. However, few studies examine its effectiveness in multiple sclerosis (MS). The study aims to investigate the effects of line dancing on balance, mood, and health-related quality of life in MS. METHODS: Participants were randomized into the line dance (n =15) and the control groups (n =16). Outcomes were measured using the Berg Balance Scale, Hospital Anxiety and Depression Scale, and Multiple Sclerosis Quality of Life-54 (MSQoL-54) at baseline and post intervention. RESULTS: Post-intervention in the line dancing group, significant improvements were observed in balance, anxiety status, and health-related quality of life. When the groups were compared, significant differences were found in balance, anxiety, and the mental health composite of the MSQoL-54. CONCLUSION: This study recommends the use of line dancing as a therapeutic intervention in MS. Nevertheless, comparisons with different intervention approaches and follow-up studies are needed.
ABSTRACT
PURPOSE: To investigate: (1) the interrater, and test-retest reliability of the figure-of-eight walk test (F8WT) in people with Parkinson's disease (PwPD); (2) the minimum detectable change in the F8WT times; (3) the concurrent and known-groups validity of the F8WT times; and (4) the cut-off times that best discriminate PwPD from healthy people and fallers from non-fallers with PD. METHODS: This was a cross-sectional study. Forty-three PwPD and 34 healthy people were recruited. The F8WT was performed along with the timed up and go test, 10 m walk test, Berg Balance Scale, Activities-Specific Balance Confidence Scale, Unified Parkinson's disease Rating Scale, and Hoehn and Yahr Scale. RESULTS: The F8WT showed good interrater and test-retest reliability (ICC = 0.964-0.978 and ICC = 0.905-0.920, respectively). The MDC was 2.77 s. The F8WT was correlated with other outcome measures. Significant differences in the F8WT times were found between PwPD and healthy people and between fallers and non-fallers with PD (p < 0.001 and p < 0.001, respectively). The cut-off times of 8.43 s best discriminated PwPD from healthy people, while 11.19 s best discriminated fallers from non-fallers with PD. CONCLUSIONS: The F8WT is a reliable, valid, and easy-to-administer tool in assessing the walking skill of PwPD.Implications for rehabilitationThe figure-of-eight walk test (F8WT) is a reliable, valid, and clinically available tool for assessing walking skill in Parkinson's disease (PD).The minimal detectable change of the F8WT is 2.77 s, which may help to determine any real change in walking skill after any intervention.The F8WT correlated with functional mobility, gait speed, balance, balance confidence, and severity and stage of PD.The F8WT times may detect impaired walking skill between people with PD and healthy people, and between fallers and non-fallers with PD.
