Clinical significance of specific spinal mobilization for patients with ankylosing spondylitis evaluated by quantitative assessments and patient interviews.
OBJECTIVE
To assess individual responses to specific spinal mobilization (SSM) in terms of spinal mobility, perceived stiffness, pain and activities of daily living (ADL) in patients with Ankylosis Spondylitis (AS), and whether and how interviews supported or supplemented the quantitative results.


METHODS
Spinal mobility was recorded by the fingertip-to-floor distance, the Modified Schober Test, myerinometer, and the chest expansion test. The measures corresponding to sites targeted by SSM was used as effect variables, and the other as control variables. Visual analogue scales assessed pain and stiffness. The Bath Ankylosing Spondylitis Functional Index assessed ADL. A single subject experimental design was applied. The patients' experiences were investigated by semistructured qualitative interviews.


RESULTS
Six patients completed 12 sessions of SSM. In five patients spinal mobility improved by 6-38%, and perceived stiffness reduced by 6-82%. Further improvements were found after three months. Improvements were not seen in the control variables. The interviews revealed that to become less stiff had various meanings for the patients, the SSM helped to get control of motion, and the conversations with the therapists enabled them to cope with the situation.


CONCLUSIONS
The findings suggest that SSM can diminish spinal stiffness, but this had different meanings for the patients. What were important were what they experienced and learnt during the therapy process.
