Introduction:
Cervical spine mobility is essential for daily functioning, sports performance, and overall spinal health. Among cervical spine motions, rotation is most strongly associated with limitations in activities of daily living (ADL). However, most corrective strategies rely on direct manipulation or stretching of the cervical spine. Reverse-motion exercises, which indirectly mobilize the cervical spine through thoracic and trunk movements, may provide a more effective and integrated alternative. This study examined the immediate and short-term effects of two reverse-motion cervical spine rotation exercises, Archer's Rotation and Python Squeeze, on cervical spine rotation range of motion (ROM).
Methods:
This study was a single-arm, 2-week intervention study. Participants first underwent the KOJI AWARENESS cervical spine mobility screening, and individuals who demonstrated rotational restrictions on this screening were selected as the study sample. A total of 17 participants (7 females, 10 males; mean age: 27.7 ± 5.8 years) completed the 2-week intervention. Cervical rotational ROM was assessed at baseline, immediately after the first exercise session, and after the 2-week intervention period. The program consisted of Archer's Rotation and Python Squeeze performed at home, with three sets of eight repetitions, 3 days per week.
Results:
Significant improvements were observed in both right and left cervical spine rotations. Right rotation increased from 60.6° ± 7.3° at baseline to 67.6° ± 7.1° immediately post-exercise and 68.5° ± 5.5° after 2 weeks (p < 0.001). Left rotation improved from 59.7° ± 5.4° to 66.5° ± 6.1° and 68.8° ± 6.0°, respectively (p < 0.001). The proportion of participants who achieved a full score on the KOJI AWARENESS cervical spine test also increased significantly after the intervention.
Conclusion:
The reverse-motion cervical spine exercises produced meaningful immediate and short-term improvements in cervical rotational ROM. These findings suggest that such exercises offer an effective, practical, and integrated method for enhancing cervical spine mobility.
