Objective:

To investigate the effects of infrared irradiation at predefined acupoints combined with task-oriented training on neurological function, limb motor recovery, electromyographic activity, daily living ability, and quality of life specifically in cerebral infarction patients with hemiplegia.

Approach:

• Study Design: A randomized controlled trial involving 208 patients with cerebral infarction and hemiplegia, allocated to either the IPA + TOT group or the TOT-only group, with evaluations conducted at baseline and week 3.
• Evaluation Metrics: Neurological impairment (NIHSS), limb motor function (FMA), electromyographic parameters (iEMG, RMS), activities of daily living (Barthel Index), and quality of life (SS-QOL) were assessed at baseline and at week 3.

Key Findings:

• IPA + TOT group showed greater improvements in Barthel index (p = 0.002), FMA-upper limb score (p = 0.025), and FMA-lower limb score (p = 0.003) compared to TOT-only group.
• Electromyographic activity increased significantly in the triceps brachii (iEMG: p = 0.035; RMS: p = 0.001) and tibialis anterior (iEMG: p = 0.037; RMS: p = 0.022) regions.
• Quality of life measured by SS-QOL was higher in the IPA + TOT group (p = 0.012).
• No significant difference in NIHSS scores between the groups.

Interpretation:

IPA combined with TOT is associated with improvements in motor function, muscle activation, daily living ability, and quality of life.

Limitations:

• Further studies with longer follow-up periods and more rigorous study designs are required to confirm long-term efficacy and clinical value.

Conclusion:

IPA combined with TOT may serve as a complementary rehabilitation strategy for cerebral infarction patients with hemiplegia.
