Stabilisation exercises for low back pain

Non-specific low back pain (NSLBP) is a major cause of long-term sickness and has estimated costs of £624 million per annum for UK employers and £1 billion for health services (Department of Health, 2000; Maniadakis & Gray, 2000; Savigny et.al., 2009). Stabilisation exercises (also known as core stability exercises) are thought to be effective at reducing pain and disability and are a popular treatment choice for back pain in the UK.

This treatment is defined as facilitation of deep muscles of the spine (primarily transverses abdominus or multifidus) at a low level, integrated into exercise and progressing into functional activity. I was keen to explore this further and found this systematic review whose objective was to evaluate the current evidence for the benefit of stabilisation exercises for low back pain.

Here’s what they did

A recent systematic review concluded that stabilisation exercises may be beneficial compared to no treatment but are unlikely to produce better outcomes than any type of exercise.  This review was updated searching PubMed, CINAHL, AMED, Pedro and The Cochrane Library between 2006 to 2013 and produced an additional 19 (from a potential 2,076) further relevant articles. Methodological quality was evaluated using the PEDro scale and the review followed PRISMA recommendations.

Here’s what they found

Twenty nine studies were included in analysis (10 from previous review).

Twenty two studies (n = 2,258) reported the post treatment effect of stabilisation exercises on  pain. Although there was significant benefit of stabilisation exercises for low back pain in the short (-7.93 (95% CI -11.74 to -4.12), medium (-6.10 (95% CI -10.54 to – 1.65)) and long term (-6.39 (95% CI -10.14 to -2.65)), when compared with any alternative treatments or control, the difference between groups was clinically insignificant.

Twenty four studies (n = 2,359) reported the post treatment effect of stabilisation exercises  on disability. Although there is significant benefit of stabilisation exercises for low back pain in the short (-3.61 (95% -6.53 to -0.70) and long term (-3.92 (95% CI -7.25 to -0.59)) when compared to alternative treatments or control, there was no difference statistically or clinically.

The authors concluded

The overall results of the meta-analysis indicate a trend favouring this intervention, which is not regarded as clinically significant, when compared with any alternative treatment or control.

Given the low levels of heterogeneity and the large number of high methodological quality studies the authors were confident that further research is unlikely to alter their conclusion.

The Musculoskeletal Elf’s view

The Musculoskeletal Elf

In 2013 Nijs et.al., challenged the role of core stability in NSLBP rehabilitation, suggesting it could encourage unhelpful beliefs on pain and movement.

In the 2008 review the majority of the studies favouring stabilisation exercises combined these with some other form of treatment, implying that the package of care was effective rather than stabilisation exercises alone.

In this updated review the majority of the studies used stabilisation exercises as sole treatment, which allowed analysis of this intervention in isolation. Five studies advocated one to one instruction where therapists dedicated between 6 to 10 hours per patient. With mounting pressures on the resources of time, capacity and funding, the use of stabilisation exercises as a sole treatment choice for NSLBP has to be questioned.

What do you think?

  • When treating people with NSLBP do you instruct solely on core stability exercises?  Are you surprised at the study findings?
  • When treating people with NSLBP do you address core stability at all?

Do you know that there is an evidence-based minimum set of items for reporting in systematic reviews and meta-analyses? This is called the Preferred Reporting Items for Systematic Reviews and Meta-Analyses or PRISMA statement and can be accessed through the website of the EQUATOR Network. The Elves use the PRISMA statement for critical appraisal of systematic reviews, although it is not a quality assessment instrument to gauge the quality of a systematic review.
