Conditions low back pain, neck pain, muscular atrophy
Treatments low back exercises 1, low back exercise 2
Sponsor Helse Stavanger HF
Start date January 2013
End date April 2017
Trial size 325 participants
Trial identifier NCT01788111, 2010/2254/REK vest, SUS-ID 294


The purpose of this project is to investigate the occurrence of neck and back pain in a population of commercial helicopter pilots, and investigate factors related to the profession that can cause these problems. The project has a biological approach assessing the supporting and stabilizing muscles (multifidus) in pilots with chronic back and neck ailments. Pilots with low back problems are invited to a controlled intervention trial to investigate whether one can achieve improved spinal health with a rigid training régime. Primary trial outcome is improved neck and back multifidus muscles pathology and function as assessed by the extent of fat infiltration -as visualized on MRI - and the volume and ability of the lumbar multifidus muscles to contract as shown with ultrasound. The perceived effect on spinal health with sick leave frequency is also evaluated.
