Isokinetic peak torque and work values for the shoulder.
The purposes of this study were to: a) measure peak torque (PKT) at 60 and 180 degrees /sec of angular velocity and work data at 180 degrees /sec of angular velocity for isokinetic muscular performance during external/internal rotation (ER/IR) and modified abduction/adduction (MOD-AB/AD) tests, b) compare the dominant and nondominant upper extremity data, and c) compare the relative peak torque between sexes. Twenty-one males and 20 females were tested isokinetically at 60 and 180 degrees /sec in MOD-AB/AD and ER/IR. A significant difference did not exist between the dominant and nondominant shoulders for the PKT. A significant difference did exist between sexes when comparing PKT, total work, and power but not when comparing endurance and agonist/antagonist PKT and work ratios. The data described demonstrated large standard deviations suggesting the need for specific categorization of persons to establish normative values. J Orthop Sports Phys Ther 1989;10(7):264-269.
