Objective: We assessed the effect of acupuncture on the recovery time of stroke inpatients under rehabilitation. Method: We retrospectively collected the medical records of 54 hemiplegic stroke inpatients. Within the hospitalization period, a total of 34 patients received therapeutic intervention combined with acupuncture and rehabilitation, whereas 20 patients received rehabilitation only. The patients’ performance in activities of daily living were assessed using the Barthel scale on admission and discharge. We applied the Cox proportional hazard model to estimate the effect. Results: For the patients who received combined acupuncture and rehabilitation therapy, the chance of a recovery of activities of daily living to a Barthel scale score ≥ 60 was 5.0 times greater than that of the control group (p = 0.03, 95% confidence interval: 1.18–21.39), and the amount of time taken was 58.7 days shorter. Conclusion: Our findings suggest that combined acupuncture and rehabilitation therapy is likely to be beneficial to shorten the time required to improve from dependency to assisted independence in activities of daily living in stroke inpatients. However, additional double-blind, randomized, control studies are needed for confirming the findings.
