Efficacy and safety of ultrasound-guided acupotomy in the treatment of spastic paralysis after stroke: a randomised controlled clinical trial study.

Researchers in China studied whether using ultrasound imaging to guide a technique called acupotomy could help stroke survivors with muscle spasticity and paralysis. Acupotomy involves using a specialized needle-scalpel instrument to release tight tissues. The study included 66 patients who had experienced stroke-related spastic paralysis and divided them into two groups: one received ultrasound-guided acupotomy and the other received traditional acupotomy without imaging guidance. The researchers measured muscle thickness, elasticity, and various functional assessments before and after treatment. Patients who received ultrasound-guided acupotomy showed significantly better improvements across multiple measures compared to the traditional approach. They had better scores on motor function tests (Fugl-Meyer Assessment), daily living activities (modified Barthel Index), and overall neurological function (Chinese Stroke Scale). The ultrasound-guided group also showed improved muscle elasticity measurements in the affected arm. The study suggests that using ultrasound to visualize the treatment area allows practitioners to locate needle points more accurately and safely. This imaging-guided approach appears to offer better standardization and repeatability compared to traditional methods that rely solely on anatomical landmarks and palpation. For stroke survivors dealing with spastic paralysis, ultrasound-guided acupotomy may represent a promising treatment option that could provide superior functional improvements compared to conventional acupotomy techniques. If you're considering acupotomy for post-stroke spasticity, seek a qualified practitioner who has specialized training in both acupotomy techniques and ultrasound-guided procedures.

This randomized controlled trial (n=66) evaluated ultrasound-guided acupotomy versus traditional acupotomy for post-stroke spastic paralysis. Patients were randomly assigned to either ultrasound-guided (n=33) or traditional acupotomy (n=33) groups and treated between June 2022-June 2023. Primary outcomes included biceps brachii thickness and elasticity measurements, Fugl-Meyer Assessment scores, modified Barthel Index, and Chinese Stroke Scale neurological deficit scores. The ultrasound-guided group demonstrated statistically significant superior outcomes across all measures (p<0.05), including improved brachial muscle and posterior biceps Emean values. Ultrasound guidance enabled direct visualization of needle placement, enhancing precision and safety. The study, registered with ChiCTR (ChiCTR2300073294), suggests ultrasound-guided acupotomy offers improved standardization, reproducibility, and clinical efficacy compared to landmark-based techniques. Clinical implications include the potential integration of ultrasound guidance into acupotomy protocols for spastic paralysis management, though larger multi-center trials are warranted to confirm these findings and establish standardized treatment parameters.
