Diagnosis of cervical and thoracic musculoskeletal spinal pain receptive to mechanical movement strategies: a multicenter observational study

Background: The McKenzie’s Mechanical Diagnosis and Therapy (MDT), which uses a combination of repeated movements and sustained positions to affect signs and symptoms, is commonly used for the conservative evaluation and management of cervical and thoracic spinal conditions. Objective: Report a consecutive cohort of neck and thoracic pain patients managed using MDT and to record their classifications and physiotherapy management strategies. Methods: Therapists provided demographic data on themselves and the patients, clinical data on the patients, and Neck Disability Index scores at baseline and final visit. Results: Sixteen therapists collected data on 138 patients at baseline, of who 120 (87%) were followed up three to five visits later; these were patients with 131 cervical and seven thoracic problems. The therapists and patients are described. Regarding MDT classifications 83% were recorded as cervical and 100% as thoracic Derangement; there was a Directional Preference for extension in 80% of cervical spine patients, and 100% of thoracic spine patients. In addition, 13% of cervical spine patients were classified as OTHER, for which specific classifications were given. Classifications remained stable between initial and discharge sessions in 94% of patients. Neck Disability Index scores reduced from a mean of 24–12 at discharge (P < 0.001). Conclusions: Routinely collected data can describe both therapists and patients involved, demonstrate the MDT classification clinical utility in terms of prevalence and stability between visits, provide information on the clinical course of this patients’ population, which could help establish treatment efficacy. Randomized controlled trials are needed to test for efficac
