Hemiplegic shoulder pain (HSP) is one of the most common distressing complication that patients may experience after stroke with a prevalence of 34% to 84%. Neurolysis (chemical, radiofrequency) of suprascapular nerve (SSN) is a long-lasting treatment option in treating HSP as SSN it provides 70% sensory innervation to shoulder articulation. A prospective randomized controlled trial was done to compare the effectiveness of ultrasound guided pulsed radiofrequency ablation and bupivacaine block of suprascapular nerve in reducing pain and disability in hemiplegic shoulder pain patients. Eighty-two patients enrolled in the study were allocated to 2 groups (Group A and B). Group A (n=41) received pulsed radiofrequency ablation while Group B (n=41) received bupivacaine block of SSN. Visual Analogue Scale (VAS), active and passive range of motion, SPADI were used as outcome measures. Group A showed better improvement in pain from baseline to 24 weeks as shown by reduction in VAS score from 7.11 ± 1.125 to 1.54 ± 1.02. Reduction in SPADI from 83.24 ± 9.67 to 37.02 ± 9.87 in Group A was significantly more than 84.11 ± 10.04 to 52.88 ± 12.52 in Group B (p=0.000).
