Abstract
Objective: To study the influence of gravitational correction on the internal (IR) and external rotators (ER) shoulder strength.
Methods: The IR and ER isokinetic strength, measured in 30° scapation, was evaluated concentrically at 60 and 240°/s and eccentrically at 60°/s in 33 healthy volunteers. Strength scores were expressed either by incorporating gravitational correction (GC) or without it.
Results: With GC, IR strength was significantly lower and ER strength significantly higher than without incorporation of this procedure.
Conclusion: The GC procedure has a significant influence on IR and ER strength and should be incorporated when strength deficits of the rotator cuff are expected.
