A descriptive study of the usage of spinal manipulative therapy techniques within a randomized clinical trial in acute low back pain.
The majority of randomized clinical trials (RCTs) of spinal manipulative therapy have not adequately defined the terms 'mobilization' and 'manipulation', nor distinguished between these terms in reporting the trial interventions. The purpose of this study was to describe the spinal manipulative therapy techniques utilized within a RCT of manipulative therapy (MT; n = 80), interferential therapy (IFT; n = 80), and a combination of both (CT; n = 80) for people with acute low back pain (LBP). Spinal manipulative therapy was defined as any 'mobilization' (low velocity manual force without a thrust) or 'manipulation' (high velocity thrust) techniques of the spine described by Maitland and Cyriax. The 16 physiotherapists, all members of the Society of Orthopaedic Medicine, utilized three spinal manipulative therapy patterns in the RCT: Maitland Mobilization (40.4%, n = 59), Maitland Mobilization/Cyriax Manipulation (40.4%, n = 59) and Cyriax Manipulation (19.1%, n = 28). There was a significant difference between the MT and CT groups in their usage of spinal manipulative therapy techniques (chi2 = 9.178; df = 2; P = 0.01); subjects randomized to the CT group received three times more Cyriax Manipulation (29.2%, n = 21/72) than those randomized to the MT group (9.5%, n = 7/74; df = 1; P = 0.003). The use of mobilization techniques within the trial was comparable with their usage by the general population of physiotherapists in Britain and Ireland for LBP management. However, the usage of manipulation techniques was considerably higher than reported in physiotherapy surveys and may reflect the postgraduate training of trial therapists.
