简要总结
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.
详细描述
Objectives
The current state of research in the field and of the investigators own clinical experience clearly shows that the role of trunk muscle function in LBP is poorly understood. Investigators will address the following research questions:
- Do persons with LBP have lower trunk muscle strength, lower trunk muscle strength endurance and lower trunk muscle activity than healthy controls?
- Are functional limitations because of LBP related to the level of muscle strength, strength endurance and activity?
To answer these questions, investigators will establish an experimental framework to study limitations in muscle function to address the following aims:
- To compare trunk muscle strength, strength endurance and activity between persons with LBP and healthy control persons.
- To determine the relationship between trunk muscle strength, strength endurance and activity, and the Oswestry Disability Index (ODI) score.
