The following 3 studies come from the Netherlands and compare the effectiveness of manual therapy (manipulation), physiotherapy and treatment by general medical practitioners for nonspecific back and neck complaints.
The Effectiveness of Manual Therapy (Manipulation), Physiotherapy, and Treatment by the General Practitioner for Nonspecific Back and Neck ComplaintsAuthors Abstract
Randomized Clinical Trial of Manual Therapy (Manipulation) and Physiotherapy for Persistent Back and Neck Complaints: Results of One Year Follow UpEditors Summary
Results for this trial revealed an interesting factor: many patients in the GP (general medical practitioner treatment group) and placebo groups changed from their assigned treatment to another treatment during the one year follow-up. This clearly indicates the superiority of manual therapy (manipulation) and physiotherapy over the other two treatments, and the willingness of patients to turn to other treatments when their assigned treatment is not effective enough. In terms of the change of the main complaint, the manual therapy (manipulation) group showed the largest improvement after 12 months follow up. Manual therapy also gave larger improvements in physical functioning than the physiotherapy group at all follow up measurements. The global perceived effect after 6 and 12 months follow up was similar for both treatments. Thus, it can be concluded that manual therapy (manipulation) and physiotherapy are superior to GP and placebo treatment, and manual therapy (manipulation) is slightly better than physiotherapy after 12 months.
Randomized Clinical Trial of Manual Therapy (Manipulation) and Physiotherapy for Persistent Back and Neck Complaints: Subgroup Analysis and Relationship Between Outcome MeasuresEditors Summary
Results showed a greater improvement in the main complaint with manual therapy (manipulation) than with physiotherapy for patients with chronic conditions (duration complaint of 1 yr or more). Improvement in the main complaint was also larger with manual therapy (manipulation) than with physiotherapy for patients younger than 40 years (both were measured after 12 months follow up). Labeling of patients as "suitable" or "not suitable" for treatment with manual therapy (manipulation) did not predict differences in outcomes. There was a moderate to strong correlation between the three outcome measures, although a considerable number of patients gave a relatively low score for perceived effect while the research assistant gave a high improvement score for the main complaint and physical functioning. This finding indicates that the outcome measures represent different features of progress in back and neck patients, and that if research interest lies in the opinion of the patient and the observer, it will not suffice to measure just one of the outcome measures. In conclusion, the subgroup analysis suggests better results of manual therapy (manipulation) compared to physiotherapy in chronic patients and in patients younger than 40 years. Future research must investigate the explorative findings of these subgroup analyses. Of particular interest may be the strong relationship between improvement of physical functioning and improvement of main complaint which can also indicate that the severity of the main complaint of a patient concurs with the patient's limitation in physical functioning.
