OBJECTIVE: To assess the effectiveness of a comprehensive rehabilitation approach combining Traditional Chinese Medicine Daoyin with lower limb robotics during the recovery phase of stroke ***: Stroke patients meeting the specified criteria were randomly assigned to one of four groups using a random number table: Control group, Daoyin group, lower limb robot group(LLR group), and Daoyin and lower limb robot group(DLLR group). Each group received distinct treatments based on conventional rehabilitation *** treatment duration spanned two weeks with two days of rest per week. Pre-and post-intervention assessments included various scales: Fugl-Meyer Assessment(FMA),Berg balance scale(BBS), Barthel index(BI), Fatigue Scale-14(FS-14), Pittsburgh sleep quality index(PSQI),Hamilton Anxiety Scale(HAMA), and Hamilton Depression Scale(HAMD).RESULTS: Statistically significant differences were observed in the lower limb function measured by FAM between the Control group(15 ± 5) and the DLLR group(18 ± 5)(P = 0.049). In the Barthel index, a statistically significant difference was noted between the Control group(54 ± 18) and the DLLR group(64 ± 11)(P = 0.041).Additionally, significant differences were found in the Berg balance scale between the Control group(21 ± 10)and the DLLR group(27 ± 8)(P = 0.024), as well as between the Control group(21 ± 10) and the LLR group(26 ± 10)(P = 0.048).CONCLUSION: The findings of this study suggest that the combined use of Daoyin and robotics not only enhances motor function in stroke patients but also has a positive impact on fatigue, sleep quality, and mood. This approach may offer a more effective rehabilitation strategy for stroke patients.
