Abstract Introduction: Codman’s pendular exercises have been widely used for decades with the intention of passively mobilizing the glenohumeral (GH) joint while not compromising recently injured or repaired tissues. However, no studies have yet shown that they actually result in true GH movement. The aim of this study was thus to quantify GH motion during pendular exercises with the hypothesis was that they involved little if any true GH motion.
Methods: 10 healthy volunteers were involved in this study. Shoulder kinematics were analyzed based on a validated biomechanical model coupling patient-specific imaging and motion capture, during which participants were instructed to perform medio-lateral, antero-posterior and circular pendular exercises. GH range of motion (ROM), scapulothoracic (ST) ROM, thoracohumeral (TH) ROM and overall exercise amplitude were calculated for each sequence. Linear regression analyses were carried out to determine any association between different components of shoulder motion.
Results: Mean overall exercise amplitudes were 36.48°±9.74° (range, 25.38 to 56.39°) for medio-lateral exercises, 38.3±14.97° (range, 20.68 to 64.99°) for antero-posterior exercises, and 21.44°±7.72° (range, 14.01 to 35.49°) for circular exercises. Mean GH and ST involvement remained minimal, ranging from 4.88 to 10.77°, and 1.4° to 4.19°, respectively. There was no significant correlation between overall exercise amplitudes and GH (R = 0.38, p = 0.01) or ST amplitudes (adjusted R2 = 0.3, p = 0.006).
Conclusion: This study demonstrates that Codman pendular exercises depend mainly on truncal movement, and produce very little movement of the GH and ST joints. The use of these exercises for passive shoulder rehabilitation is thus questionable.
