Neuronavigation-assisted aspiration and electro-acupuncture for hypertensive putaminal hemorrhage: A suitable technique on hemiplegia rehabilitation

Aim: To identify whether neuronavigation-assisted aspiration (NA) combined with electro-acupuncture (EA) provides better motor recovery in events of hypertensive putaminal hematoma (HPH) sized 30 to 50 ml. This study aims to examine whether neuronavigation-assisted aspiration and electro-acupuncture have additional value to cerebral hemorrhage motor rehabilitation. Material and Methods: 240 patients with HPH sized 30 to 50 ml and admitted within 6 to 10 hours after stroke ictus were included in this study. Group 1 contained 60 patients who underwent neuronavigation-assisted aspiration and electro-acupuncture (NAEA), group 2 contained 60 patients who underwent neuronavigation-assisted aspiration (NA), group 3 contained 60 patients who underwent electro-acupuncture (EA), and group 4 contained 60 patients who received conservative therapy consisting solely of medications. All the patients received the same therapeutic plan on admission and functional exercises three days after stroke onset. Electro-acupuncture was performed on the third day of admission; motor recovery was examined on weeks zero and eight by blinded assessors. Outcome measures included Fugl-Meyer assessment, modified Ashworth Scale and Functional Independence Measure. Results: Group one showed significantly improved motor outcomes compared to group four (p < 0.01). Group one also showed significant motor improvement when pre-and post- therapy functioning was examined (p < 0.01). Cerebral edema and ischemia were significantly decreased in group one compared to group 3 and 4 (p < 0.05). While not as effective as group one treatment, group two and group three patients had significant motor recovery after intervention when compared to group four (p < 0.05). Muscular tension secondary to stroke was considerably improved between group one and group four, group two and group four, group three and group four respectively (p < 0.05). Activities of daily living (ADL) improved a lot with EA together with NA. Conclusion: Neuronavigation-assisted aspiration and electro-acupuncture of HPH at the early stage can provide improved motor recovery with fewer complications. Significant motor recovery can be achieved by neuronavigation-assisted aspiration with acupuncture. Based on our findings, we recommend early intervention with NA and EA in order to promote early rehabilitation of hemiplegia secondary to HPH.
