Key Finding
Combined robot-assisted training and acupuncture produced significantly greater improvements in lower limb motor function, gait parameters, and daily living activities compared to either therapy alone in stroke patients.
Researchers analyzed 21 studies involving 1,821 stroke patients to determine whether combining robot-assisted training with acupuncture could improve leg function better than either treatment alone. Robot-assisted training uses robotic devices to help patients perform repetitive leg movements, while acupuncture involves inserting thin needles at specific points on the body. The combined approach was compared against conventional rehabilitation, robot therapy alone, or acupuncture alone.
The results showed that patients receiving both robot-assisted training and acupuncture experienced significantly better outcomes across multiple measures. They demonstrated greater improvements in lower limb motor function, walking ability, balance, and independence in daily activities compared to those receiving single treatments. Gait parameters also improved notably—patients walked with longer steps, faster speed, and better step width. These improvements were consistent across all studies analyzed, suggesting the combination therapy is more effective than either treatment by itself.
For stroke survivors struggling with leg weakness or walking difficulties, this research suggests that combining robotic rehabilitation with acupuncture may offer enhanced recovery benefits. The dual approach appears to address motor recovery from multiple therapeutic angles, potentially accelerating the rehabilitation process. While both therapies have shown individual merit, their combination may produce synergistic effects that amplify recovery outcomes.
If you're considering acupuncture as part of your stroke rehabilitation program, consult with a licensed acupuncturist who has experience treating neurological conditions and can coordinate care with your rehabilitation team.
This systematic review and meta-analysis evaluated 21 RCTs (n=1,821) comparing robot-assisted training (RAT) combined with acupuncture therapy (AT) versus monotherapies or conventional rehabilitation for post-stroke lower limb recovery. Registered with INPLASY (INPLASY2024120107), the study searched eight databases and assessed bias using Cochrane RoB 2.0.
Meta-analyses demonstrated statistically significant improvements favoring RAT plus AT across all outcome measures: FMA-LE (MD=4.02, 95% CI [3.12, 4.93]), FAC (MD=0.66, 95% CI [0.43, 0.89]), MBI (MD=9.88, 95% CI [6.43, 13.33]), and BBS (MD=6.79, 95% CI [5.43, 8.16]). Gait parameters also improved significantly: step length (MD=7.42 cm), step speed (MD=0.16 m/s), and step width (MD=-2.22 cm). Heterogeneity ranged from moderate to high (I²=12-90%), though sensitivity analyses confirmed robustness.
Clinical takeaway: Combined RAT and acupuncture demonstrates superior efficacy over monotherapies for lower limb motor recovery, functional ambulation, and ADL independence in stroke patients, supporting integrative rehabilitation protocols.
