What is the background to this research?[edit | edit source]
In modern society, lower back pain (LBP) is one of the most prevalent physical disorders that affects performance at work as well as general well-being across all ages. [1]
Chronic pain is closely associated with structural and histomorphological changes in spinal muscles. These back muscles, become fatigued through over-exertion. Over time poor coordination of the spinal muscles leads to chronic LBP.[2]
Exercise can be a proactive treatment for improving muscle strength, endurance and functional impairment amongst low back pain patients.
Many avenues of physical activity have been referred to and introduced in the study, but no superior exercise mode was suggested.
This study aims to compare the effectiveness of two exercises that can help reduce LBP, namely individualised graded lumbar stabilisation exercises (IGLSE) and walking exercises (WE).

The study format was a RCT with a total of 48 participants who all experienced chronic LBP. Within the study there were 4 experimental groups: flexibility exercise, walking exercise, stabilisation exercise, and stabilisation with walking exercise. The study duration was 6 weeks.
Lower back pain is a widespread common chronic condition, exercise is one of the most effective treatment strategies and there is a pleather of available research on PubMed.
In comparison to similar studies this research involved a smaller testing population and was shorter in duration.
The participants were randomly sorted into 4 different groups, and performed the appropriate exercises.
Dosage: 30-60mins sessions, completed 5 times/week, for 6 weeks in total
Education: All participants received education surrounding correct and healthy posture for managing LBP as well as how to engage and brace their abdominal muscles.
Primary outcome measurement:
Visual analog scale(VAS) of their pain during physical activity and at rest.
Secondary outcome measurement:
VAS of radiating pain measured at rest and during physical activity
Individual medication dosage (number of times/day)
Oswestry disability index
Beck depression inventory
Endurances of patient in specific postural positions
Strength of lumbar extensors
Methodology
This research used a randomised control trial format and the subjects were recruited from the universities outpatient rehab clinic.
The RCT structure of this study makes for reliable and accurate comparisons between the exercise groups.
Limitation
The causes or severity of each patient's lower back pain was not disclosed during the study.
The duration of research could have been extended to assess the long term effects of the exercises.
The results from this study only reflect the short term benefits as opposed to positive changes overtime.
The types and effects of medications participants were using during study were not considered as a contributing factor to the results.
LBP reduced during physical activity across all four experimental groups
LBP reduced at rest: FE group and SE group
Frequency of medication use decreased in the FE group
Exercise frequency increased: SE, WE
The highest compliance: SE group
Overall there were no clinically significant differences between the 4 experimental groups
Interpret
Clinicians from the study confidently recommended SE and WE as suitable treatments for patients experiencing chronic LBP. The exercises were found not only to relieve lower back pain but in addition, improved overall muscle endurance, core stability and prevented the progression of LBP.
The results from the WE group and the stabilisation training + WE group produced substantial improvements in the muscle endurance of the back muscles.
Researchers also identified the beneficial contribution posture related education and muscle bracing exercises produced within all experimental groups
What conclusions can we take from this research?[edit | edit source]
As a result of this study, there is no doubt that the exercise treatments were effective in the LBP patients.
As the research highlighted, the combination of targeted exercises, stabilisation and postural training as well as patient education are effective in reducing LBP related symptoms and altering the management of their pain through adjusting the patient's perspective of treatment options
Exercises including walking, lumbar stabilisation, postural training and stretching are low cost activities that do not require any additional equipment and can be completed in any setting at a time of convenience. In addition, these exercises are easy to self-pace and adapt to avoid high levels of fatigue and exhaustion, the sets and reps can be modified to increase the recovery period.
Maintaining compliance to the exercises outside of a clinical setting could be hard to continue due to barriers in patient motivation and the lack of persistent feedback.[3]
According to additional research some strategies for increasing compliance and patient motivation include group sessions, involving a second person such as a a friend or family member and keeping an exercise log/diary.[4]
