Reliability of a Simple Physical Therapist Screening Tool to Assess Errors during Resistance Exercises for Musculoskeletal Pain
Figure 2
(a) and (b) provide examples of how the joint positions deviations were observed and evaluated. The picture series show possible error positions to either side from the ideal position of the elbow in the sagittal plane from a side view (a) and supination/pronation deviations from ideal of the forearm in the unilateral shoulder external rotation exercise. Pictures show the right side. Negative deviations were denoted for angles below 90 degrees of the joint and positive deviations were applied to angles above 90 degrees.
