The goal of this clinical trial is to learn if pericapsular nerve group block (PENG) in shoulder scope surgery provides adequate analgesia with less affection of muscle power compared to interscalene block. The main questions it aims to answer are: Does PENG block provide analgesia similar to interscalene block? Does PENG block have less or no effect on muscle power compared to interscalene block? Researchers will compare PENG block with interscalene block Participants will: Receive either PENG or interscalene block before shoulder scope surgery Be evaluated for their motor power after receiving the block and after the surgery Be evaluated for pain after the surgery
