Effects of dual task training on trunk impairment and mobility in stroke

Aim. To evaluate the effects of dual task training and single task oriented training on trunk impairment, mobility, and quality of life in individuals post-stroke. Material and methods. Participants (n = 32), aged 40–60 years, with moderate stroke severity (Chedoke–McMaster Stage 2) and adequate cognitive function (MMSE score ≥ 24), were recruited using convenience sampling. Participants were randomly assigned to either a single-task training (STT) group or a combined dual-task training (DTT) group. Both groups received task-oriented training, while the DTT group additionally performed dual-task activities. Interventions were conducted three times per week for 10 weeks. Outcomes were assessed using the Trunk Impairment Scale (TIS), Postural Assessment Scale for Stroke (PASS), Timed Up and Go test (TUGT), WHO Quality of Life-BREF (WHOQOL-BREF), and Modified Ashworth Scale (MAS). Results. Significant improvement (p < 0.001) was observed in the experimental group from baseline to 10 weeks regarding functional independence (14.6 ± 1.3 vs. 25.6 ± 2.5), mobility (25.8 ± 0.9 vs. 14.8 ± 1.0), and quality of life (49.9 ± 4.1 to 74.3 ± 6.3). Furthermore, trunk impairment (11.7 ± 1.1 vs. 16.2 ± 0.9) also improved significantly (p < 0.05). Conclusions. The addition of a dual-task exercise training program demonstrated effectiveness in enhancing various aspects of function in stroke survivors, such as mobility, balance, quality of life, and trunk impairment.
