''Is the muscle activity of the lower back muscles changed after short term slump sitting? ''Samenvatting
Background information: Slumped sitting is associated with decreased back muscle activity and proprioception disturbances. An active posture is advocated to prevent those effects. Altered muscle activation patterns, disturbed proprioception and multifidus atrophy are commonly seen in people with low back pain. Slump sitting is a suspected risk factor for the development of low back pain.
Research question: "Is there a change in the back muscle activity after 20 minutes of slump sitting compared to 20 minutes of active sitting in young, healthy subjects?"
Study design: randomized controlled crossover study
Method: 19 healthy, young subjects were randomly assigned to start sitting actively on a gymball or slumped on a backless chair for 20 minutes. Before each sitting period they walked for 20 minutes. The activity of the lumbar multifidus and iliocostalis was measured at baseline and after both sitting conditions with superficial electromyography in seated balance and normal sitting for 60 seconds each.
Results: No significant difference was found when measuring on the balance board. On the normal surface, the activity of the iliocostalis and multifidus after both sitting positions was higher than the baseline. When comparing the activity of the multifidus with the illiocostalis, no significant difference could be found.
Conclusion: The differences after sitting and walking stresses the importance of active breaks during prolonged sitting to prevent low back pain. Stability and coordination training can be recommended to prevent altered muscle activation patterns that are related with low back pain.
