The occurrence of shoulder pain after stroke is quite common in hemiplegia. Shoulder pain can negatively affect rehabilitation outcomes. It may not only interfere with shoulder function, but also interfere with balance, walking, transfers and performance of self-care activities. Many treatment options are available depending on cause of HSP like analgesics, anticonvulsants like (gabapentin or carbamazepine), oral corticosteroids, steroid injection (intra-articular or subacromial or biceps tendon sheath ), stellate ganglion block, manipulation, non-pharmacological modalities like positioning of affected limb, passive range of motion exercises, sling when upright, transcutaneous nerve stimulation, ultrasound, functional electric stimulation.

               Pulsed radiofrequency ablation of suprascapular nerve and suprascapular nerve block both have been proved to produce good results in primary care as suprascapular nerve supplies 70 percent sensory supply of the shoulder joint, but there is no comparative study between ultrasound guided radiofrequency ablation of suprascapular nerve and suprascapular nerve block available in literature at present. Therefore a randomized controlled study will be done in the Department of Physical Medicine and Rehabilitation, Regional Institute of Medical Sciences; Imphal to compare the effectiveness between ultrasound guided radiofrequency ablation of suprascapular nerve and suprascapular nerve block in reduction of pain and functional disability in HSP. The outcome variables will be measured before starting intervention (baseline) and at 1, 4, 12 and 24 weeks post-intervention follow up. Data will be analyzed by using SPSS Version 21. To represent descriptive statistics, mean and standard deviation will be used, for analytical statistics independent t test will be used and p-value < 0.05 will be taken as significant.
