| Shin et al12 | Randomized clinical trial | n = 26 | Group 1: unspecified cervical traction Group 2: Chuna manipulative therapy (stated to be ‘analogous to chiropractic manipulation’) | Manuscript was not peer-reviewed |
| Moretti et al14 | Randomized clinical trial | n = 80 | Group 1: Manipulative therapy and traditional physiotherapy Group 2: traditional physiotherapy | Patient population suffered cervicobrachialgia of mechanical origin |
| Walker et al15 | Randomized clinical trial | n = 98 | Group 1: cervical joint thrust and non-thrust mobilization, muscle energy or stretching techniques and a standard home exercise program Group 2: postural advice, cervical ROM exercises, subtherapeutic ultrasound and encouragement to maintain daily activities. | No subgroup specifically identified with CR was listed. |
| Honet & Puri16 | Prospective case series | n = 82 | Group 1: Cervical collar for 4 days, then over-the-door continuous traction at home with standard medication Group 2: received outpatient care, intermittent cervical traction Group 3: hospitalization, horizontal cervical bed traction, standard medication and surgical consultation after 10–21 days | No HVLA procedures were utilized in the cervical spine |
