• Study Type: observational
• Target: 36

Brief Summary

The research questions are if persons with low back pain (LBP) have lower trunk muscle strength, lower trunk muscle strength endurance and lower trunk muscle activity than healthy controls and if functional limitations because of LBP are related to the level of muscle strength, strength endurance and activity. To investigate this investigators will carry out a clinical assessment including questionnaires and a biomechanical assessment comprising muscle strength tests, muscle strength endurance tests and electromyographic (EMG) analysis of selected trunk muscles.
