Movement Quality and Balance Improvement in People With Chronic Low Back Pain Following Trunk Muscle Training

Официальное название

Trunk and Lower Limb Movement Quality and Stability Improvement in People With Chronic Low Back Pain Following Different Types of Isometric Trunk Muscle Training

Обзор

The goal of this project is to assess if Chronic Low Back Pain (CLBP) participant's movement quality and balance variables can change after training that decreases their pain and disability. It will also compare the difference between structural exercise (SE) and isolated trunk exercise (ITE). The main questions it aims to answer are: 1. What are the effect of the training on the participant's movement quality and balance. 2. What are the difference between different types of trunk muscle training on people with CLBP. Researchers will compare SE, ITE and control. Control group will receive back school education that was shown not to be effective in reducing pain and disability. Participants will: 1. Do home and in-lab based SE or ITE training, or maintain active daily living over 2 months. 2. Complete the pain and disability questionnaire and do several physical functioning tests while having their trunk and lower limb movement and muscle activation measured.

Подробное описание

Both ITE and SE training are equalized in terms of training intensity based on rate of perceived exertion, training duration per session, training frequency, and intervention period. Training intensity measurement does not use other methods of quantification as ITE training does not increase heart rate or blood lactate significantly regardless of the intensity.

Вмешательства

• Поведенческое Structural Exercise
  Multi-joint limb movement with force vector through the spine. The spine is held at neutral position
• Поведенческое Isolated Trunk Exercise
  Holding the spine in neutral position with no limb movement, with static loading through the spine
• Поведенческое Back school
  Patient education that has been proven to not be effective and has been used as control in past low back pain intervention studies
