Abstract：Objective To evaluate the efficacy of computer vision-guided platelet-rich plasma(PRP)treat-ment in patients with post-stroke upper limb complex regional pain syndrome(CRPS)and assess its impact on upper limb function and daily living abilities.Methods This prospective,randomized controlled trial enrolled 90 patients meeting CRPS diagnostic criteria from July 2022 to December 2023.Participants were randomly assigned to a control group(n=45)or an observation group(n=45).The control group received standard physical therapy for 30 minutes daily over 3 weeks,while the observation group underwent the same physical therapy plus one weekly PRP injection guided by a com-puter vision system.Outcome assessments were performed using the simplified Fugl-Meyer Assessment for the Upper Ex-tremity(FMA-UE),the UCLA Shoulder Function Score,and the Visual Analog Scale(VAS)for pain before and after treatment.Results Baseline comparisons revealed no significant differences between the groups in FMA-UE,UCLA,or VAS scores(P>0.05).Post-treatment,although FMA UE scores did not show significant changes(P>0.05),both groups demonstrated significant improvements in UCLA scores and VAS ratings(P<0.05).Notably,the observation group exhibited significantly greater improvements in shoulder function and pain relief compared to the control group(P<0.05).Conclusion Computer vision-guided PRP treatment effectively alleviates pain and enhances shoulder joint mob-ility and function in post-stroke CRPS patients.However,its impact on overall upper limb motor function remains incon-clusive,necessitating further investigation to fully determine its therapeutic potential.
