Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Volunteers, who meet the inclusion criteria will be given an information sheet and asked to sign the consent form. They will then undergo a screening for contra-indications to
thoracic spinal manipulation. After a volunteer has passed the screening test they will be enrolled in the trial and given a trial specific ID number. Baseline measurements for each participant will then be taken. Participants will then be allocated to one of the two trial groups according to a computer generated random number sequence.

Sample size calculation

Minimum clinically important difference in lung volume (FVC) = 200 ml
Standard deviation = 480ml (obtained from previous studies)
Power = 0.8 (80%)
Alpha = 0.05
Minimum sample size for two sample t-test = 92 per group
Minimum cohort size (i.e. 2 groups) is 2 x 92 = 184
Assuming a drop-out rate = 10%
Minimum cohort size = 202 (2 Groups @ 101)

Summary
Brief summary
The aim of this study is to measure the medium to long term effects on lung function, exercise capacity and quality of life of a new combination of interventions for people with COPD. The interventions are manual therapy and exercise. The rationale behind the study is that manual therapy delivers short-term improvements in respiratory mechanics which delays the onset of exercise-induced breathlessness. This permits an increase in exercise performance and ultimately exercise capacity. As exercise capacity is an indicator of mortality in COPD, any increase represents an improvement in the long-term prognosis of the disease.
