Effect of Induced Rotator Cuff Muscles Fatigue on Hand Grip Strength in Adults

"Each subject will undergo two separate fatigue protocols from distinct shoulder abduction angles (30° and 90°), referred to as Protocol A and Protocol B, respectively.~Fatigue will be induced using the Biodex System 4 Pro Isokinetic .Participants will be seated with the tested arm positioned at the designated shoulder abduction angle and elbow flexed at 90°. The arm will be secured using a shoulder adapter to ensure standardized positioning. Hand Grip strength will be assessed using a Jamar Plus+ Digital. Participants will perform three maximal grip trials, each lasting 3 seconds, with verbal encouragement provided. The average of the three trials will be used as the maximum voluntary contraction"
