Effects of Single-Task Versus Dual-Task Training on Balance Performance in Elderly Patients With Knee Osteoarthritis

Abstract

Objectives: This study aims to compare the effects of single-task and dual-task training on balance performance in elderly patients with knee osteoarthritis (OA). Patients and methods: Fifty elderly osteoarthritic patients with balance impairment (16 males, 34 females; mean age 72.9±5.5 years; range 65 to 84 years) were included in this study. Patients were randomly assigned to single-task balance training (group 1) or dual-task balance training (group 2) groups. Balance activities were given to both groups for three times a week for four weeks. Patients in group 2 also performed cognitive tasks simultaneously with these exercises. Patients were evaluated with Berg balance scale (BBS), kinesthetic ability trainer static and dynamic scores, timed up and go (TUG) test and walking speed (WS) for single and dual tasks, number of stopping and activities-specific balance confidence (ABC) scale at baseline and at the end of four weeks. Results: At the end of the therapy, there were statistically significant improvements in BBS, KAT 2000 static and dynamic scores, TUG test and WS for single and dual tasks, number of stopping and ABC scale in both groups (p<0.05). But there was no statistical difference in any parameter between the groups (p>0.05). Conclusion: Both single-and dual-task trainings are effective in improving balance performance under single-and dual-task conditions in elderly patients with knee OA. Dual-task training is not superior to single-task training for balance improvement in elderly osteoarthritic patients.

Star Excursion Balance Test as an Exercise to Improve Static and Dynamic Balance in Community-Dwelling Persons with Unilateral Osteoarthritis of Knee

“…31 In this present study, the post-intervention dynamic balance improved in the exercise group as measured by the TUG. Our finding was in line with UzunkulaoGlu et alwho recently illustrated that the balance training with tandem movements improved from 13.2 to11.2 s. 32 Moreover, the time spent for TUG in the present study was lower than those previously reported fall risk cut-off points . 33,34 In conclusion, these findings suggested that 30-minute SEBT exercise training 3 times/week for 4 weeks was efficient to improve static and dynamic balance in the persons with the unilateral OA knee.…”

Comparison of BRACE (balance, resistance, aerobic, cognitive exercises) and proprioceptive training on balance and mobility in knee osteoarthritis.

“…In knee OA patients an effective assessment of balance control is necessary before management of condition. 7 Aslihan in 2020 compared effect of performance of single versus dual task exercise on balance in elderly persons with knee osteoarthritis (KOA). They concluded that dual task exercises was not superior to single task exercises for improving balance in knee OA patients.…”

“…They concluded that dual task exercises was not superior to single task exercises for improving balance in knee OA patients. 7 In 2019 Gulsen reported that greater numbers of falls in older people with knee osteoarthritis (KOA) has been experienced by participants with no OA. Balance tests were applied with Tetrax Interactive Balance System, Berg Balance Scale (BBS) was applied formeasured the balance of patients.…”
