Study Arms:
- Chuna manual therapy (Type: EXPERIMENTAL): The Chuna manual therapy group will receive Chuna manual therapy alone. Chuna manual therapy will employ a semi-standardized treatment plan of Chuna manual therapy through Chuna technique selection based on physician judgement of techniques from Chuna Medicine (Korean Society of Chuna Manual Medicine for Spine \& Nerves: Chuna Medicine: Seoul: Korean Society of Chuna Manual Medicine for Spine \& Nerves; 2017) and osteopathic manipulative medicine. The Chuna techniques employed in this study are divided into cervical, thoracic and rib cage, lumbar, pelvic, sacral, pubic, and hip joint area techniques. Chuna manual therapy sessions will be administered 2 sessions/week over a period of 5 weeks (total 10 sessions). The time duration of 1 Chuna manual therapy session will consist of approximately 10-20 minutes of diagnosis and approximately 10 minutes of treatment.
- Usual care (Type: ACTIVE_COMPARATOR): The usual care group will receive usual care alone. Usual care will be limited to physical therapy and conventional medication in this study. Usual care will be provided with reference to a list of most frequently used treatments in neck pain-related patients from Korean Health Insurance Review and Assessment (HIRA) 2014 statistics. Frequency and types of physical therapy used will be recorded in a separate electronic case report form for outcome assessor blinding purposes.

Based on this trial design, predict the completion outcome and termination type (if applicable).
