Implications for Rehabilitation
Complex joint motions that occur naturally (unconsciously) about some axes should be taken into account in interventions for range of joint motion (ROM).
The data obtained through this study simultaneously indicating multiple interrelated angles can be used as reference values for maximum active ROM.
ROM in the directions of motion involved in the various tasks (for example, elevation angle during shoulder flexion) may have a role to play in evaluating and setting goals for patients with impaired ROM of the arm joints.
