High Intensity Training With Non-specific Chronic Low Back Pain

Low back pain is a common disorder, occurring worldwide in both males and females in all age groups1. The prevalence is higher in females and the incidence peaks between 30 and 65 years. It is currently the most frequent musculoskeletal cause of functional disability and it has a major socio-economic impact on today's society. Although a small percentage of persons with low back pain can be diagnosed with a specific underlying cause, almost 90% of persons with low back pain present with symptoms of nonspecific origin. A part of these symptoms are only of short duration, but 23% of all people will develop nonspecific chronic low back pain (NSCLBP).

Exercise therapy (ET) is currently an important component in the treatment of NSCLBP. Previous studies analysed the effects of various modes of exercise therapy, such as motor control therapy, core stability training and aerobic conditioning training. However, therapy outcomes can be low, and guidelines in favour of using a specific program are contradictory. It thus still remains unclear which therapy modality is best suited. Furthermore, no recommendations are available about optimal training intensities during rehabilitation of persons with NSCLBP.

Since as well aerobic as muscular deconditioning are apparent in persons with chronic low back pain and improvements in overall physical fitness can affect therapy outcomes in this population, ET specifically focussing on physical fitness can be advocated for NSCLBP rehabilitation. High Intensity Training (HIT), has been promoted as an effective and efficient training method for improving physical fitness and health related parameters in healthy persons. Also, HIT resulted in successful reconditioning and improvement of functional and disease related outcomes in persons with other chronic diseases such as multiple sclerosis, heart failure, COPD and cardiometabolic diseases. Although some studies showed promising results for the effect of HIT on low back pain such as high intensity isolated, evidence is still scarce and study results are unclear because of methodological shortcomings.To evaluate HIT for the rehabilitation of persons with NSCLBP, a therapy program was developed consisting of high intensity interval cardio and high load whole body strength training.

The aim of this pilot study is 1) to evaluate the feasibility of a HIT program for the rehabilitation of persons with NSCLBP, and 2) to evaluate the effects of a HIT program on disease related outcomes and physical fitness compared to a conventional rehabilitation program in persons with NSCLBP.

Primary outcomes

  1. Pain

    Time frame: day 1

    Numeric Pain Rating Scale (NPRS) The NPRS is a nominal scale on which the participant indicates the amount of pain he/she perceives at that current moment. It consists of a line indicating eleven successive scores (0-10), whereby score 0 means 'no pain' and score 10 means 'worst pain imaginable'. An improvement of 2 levels or more is accepted as clinically relevant

  2. Pain

    Time frame: week 6

    Numeric Pain Rating Scale (NPRS) The NPRS is a nominal scale on which the participant indicates the amount of pain he/she perceives at that current moment. It consists of a line indicating eleven successive scores (0-10), whereby score 0 means 'no pain' and score 10 means 'worst pain imaginable'. An improvement of 2 levels or more is accepted as clinically relevant

  3. Kinesiophobia

    Time frame: day 1

    Tampa Scale for Kinesiophobia (TSK) The TSK is an ordinal 17 item questionnaire that inventories pain-related fear of movement for persons with subacute and chronic low back pain or fibromyalgia41,42. A higher score relates to more pain-related fear.

  4. Kinesiophobia

    Time frame: week 6

    Tampa Scale for Kinesiophobia (TSK) The TSK is an ordinal 17 item questionnaire that inventories pain-related fear of movement for persons with subacute and chronic low back pain or fibromyalgia41,42. A higher score relates to more pain-related fear.

  5. physical disability

    Time frame: day 1

    Roland Morris Disability Questionnaire (RMDQ) The RMDQ is an ordinal 24 item questionnaire for evaluating the disability level of the patient with low back pain with regards to activities of daily living33,35. A higher score correlates to a higher level of disability and a change of 5 is the minimal clinically important difference36

  6. physical disability

    Time frame: week 6

    Roland Morris Disability Questionnaire (RMDQ) The RMDQ is an ordinal 24 item questionnaire for evaluating the disability level of the patient with low back pain with regards to activities of daily living33,35. A higher score correlates to a higher level of disability and a change of 5 is the minimal clinically important difference36

  7. Endurance capacity

    Measured by Dual Energy X-ray absorptiometry (DEXA)

  10. Body composition
