NCT04257253

Brief Summary

This study evaluates the effect of a supervised exercise program on paraspinal muscle morphology and function, as well as disability/function in patients with non-specific chronic low back pain. Half of the participants will do a targeted paraspinal muscle exercise program, while the other half will do a general exercise program.

Outcome Measures

Primary Outcomes (2)

  • Change in multifidus muscle size (cross-sectional area)

    Multifidus muscle cross-sectional area measurements will be obtained from magnetic resonance imaging (MRI) from L1 to L5 spinal levels.

    Baseline, 6-week, 12-week

  • Change in multifidus muscle fatty infiltration

    Multifidus muscle fatty infiltration (composition) measurements will be obtained from magnetic resonance imaging (MRI) from L1 to L5 spinal levels.

    Baseline, 6-week, 12-week

Secondary Outcomes (12)

  • Change in12-item Short Form Health Survey (SF-12)

    Baseline, 6-week, 12-week, 24-week

  • Change in Oswestry Low Back Pain Disability Index (ODI)

    Baseline, 6-week, 12-week, 24-week

  • Change in The International Physical Activity Questionnaire (IPAQ)

    Baseline, 6-week, 12-week, 24-week

  • Change in Tampa Scale of Kinesiophobia (TSK)

    Baseline, 6-week, 12-week, 24-week

  • Change in Visual Numerical pain rating scale (NPR)

    Baseline, 6-week, 12-week, 24-week

  • +7 more secondary outcomes

Study Arms (2)

Targeted exercise program

EXPERIMENTAL

Targeted motor control and isolated lumbar extensor strengthening exercises. Supervised 12-week program, 2 times a week.

Other: Targeted exercise program

General exercise program

ACTIVE COMPARATOR

General exercise program including upper body and lower body strengthening and flexibility exercises. Supervised 12-week program, 2 times a week.

Other: General exercise program

Interventions

Participants in this experimental intervention group will perform a combination of motor control and isolated lumbar extensor strenghtening exercises. The level of difficulty of the exercises will be progressed gradually. The intervention will last 12 weeks, and each participant will have 2 supervised exercise sessions per week.

Targeted exercise program

Participants in this active intervention group will perform a generalized exercise program comprising upper-body and lower-body and hip strengthening exercises, as well as flexibility. The level of difficulty of the exercises will be progressed gradually. The intervention will last 12 weeks, and each participant will have 2 supervised exercise sessions per week.

Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • chronic nonspecific LBP (\>3 months), defined as pain in the region between the lower ribs and gluteal folds, with or without leg pain
  • currently seeking care for LBP
  • between 18 and 60 years of age
  • English or French speaker
  • score of "moderate" or "severe" disability on the ODI questionnaire
  • do not currently engage in sports or fitness training specifically for the lower back muscles (3 months prior the beginning of the study).

You may not qualify if:

  • evidence of nerve root compression or reflex motor signs deficits (e.g. weakness, reflex changes, or sensory loss with same spinal nerve)
  • previous spinal surgery or vertebral fractures
  • other major lumbar spine structural abnormalities (e.g. spondylolysis, spondylolisthesis, or lumbar scoliosis \>10°)
