Abstract

Abstract:

Objective

To explore the effect of motor imagery training (MIT) combined with task-oriented training (TOT) on lower limb function in patients with hemiplegia after stroke.

Methods

A total of 93 stroke patients with hemiplegia admitted to the Rehabilitation Department of Hefei Second People's Hospital from January 2024 to January 2025 were selected as the study subjects. They were randomly divided into a control group (31 cases), an MIT group (31 cases), and a combined group (31 cases) using a random number table method.All three groups received conventional rehabilitation treatment. The control group received 30 min of healthy lower limb training on this basis, while the MIT group received additional MIT, the combination group received a combination of MIT and TOT. All interventions lasted for 4 weeks. Lower limb motor function, balance function, gait function, and activities of daily living were assessed using the Fugl-Meyer assessment scale lower extremity portion (FMA-LE), Berg balance scale (BBS), Tinetti gait assessment scale (TGA), and modified Barthel index (MBI) before treatment and after 4 weeks of intervention.

Results

After 4 weeks of intervention, the FMA-LE, BBS, TGA, and MBI scores of patients in all three groups were significantly improved compared to those before treatment within the same group. Furthermore, the FMA-LE score (23.45±3.11), BBS score (44.13±5.28), TGA score (9.29±1.53), and MBI score (73.61±9.27) in the combined group were significantly better than those in both the control group and the MIT group, with all differences being statistically significant (P<0.05).

Conclusions

MIT combined with TOT can effectively improve the lower limb function of patients with hemiplegia after stroke.
