Plain English Summary

Background and study aims
Low back pain is a common cause of disability and can make daily functioning difficult. Some females who have given birth by C-section may have low back pain for a long time afterwards or on a regular basis. Exercise and physical activity are some of the ways in which patients can relieve their low back pain, and this can sometimes be supervised by a physical therapist.
This study aims to look at the difference between a core stability exercise program for women with post-C-section low back pain, either supervised by a physical therapist or unsupervised at home.

Who can participate?
Women who have had low back pain as a result of a C-section for at least 2 months

What does the study involve?
Participants will be randomised into 2 groups. Both groups will receive the same core stability exercise training for a period of 6 weeks; however, Group I will undergo a supervised program, whereas Group II will undergo an unsupervised program. Both groups will also receive a hot pack to use.
Group I will receive supervised training, with 3 sessions per week for 6 weeks. Every 2 weeks, participants will progress to the next level of the exercises. Group I will also receive TENS treatment.
Group II will have 1 training session and will be provided with written materials explaining how to complete the exercises at home, and will be provided with a hot pack to use at home.

What are the possible benefits and risks of participating?
The possible benefits of taking part for participants is that they may have relief from low back pain and their core muscle strength will improve. There are no known risks to participants taking part in this study.

Where is the study run from?
Helping Hand for Relief and Development (HHRD) Comprehensive Rehabilitation Centre Chakwal, Pakistan

When is the study starting and how long is it expected to run for?
February 2018 to December 2018

Post C-section low back pain


Informed consent will be taken from all the study participants. The participants will then be asked to complete Oswestry Disability Index and a questionnaire of open-ended questions. 40 participants will be assessed relating to low back pain associated with having had a C-section. 31 of these participants will be selected by convenient sampling. Following this, participants will be randomly assigned into either group I (14 participants) or II (17 participants) using the see through envelope method. Both groups will receive the same core stability exercise program; however, group I will be treated with a supervised version, whereas group II will be provided with an unsupervised, home-based core stability exercise program. Both the supervised and unsupervised programs have a duration of 6 weeks.

The core stability program consists of the following exercises:
1. Level I: weeks 1-2 - easy strengthening exercises:
1.1. Supine abdominal draw-in with single knee to chest, with heel slide and with double knee to chest:
1.1.1. Supine twist
1.1.2. Prone bridging on elbow
1.1.3. Side bridging on elbow
1.1.4. Prone cobra
1.2. Supine glute lift with arm at side, across chest and with single leg lift
2. Level II: weeks 2-4 - medium strengthening exercises:
2.1. Abdominal draw-in with feet on medicine ball and with feet on ball with movement added:
2.1.1. Supine dead bugs
2.1.2. Rolling like a ball
2.1.3. Prone bridging on elbows with single leg hip extension
2.1.4. Side bridging on elbows with single leg hip abduction
2.1.5. Quadruped opposite arm/leg raise (can add weight or dumbbell)
2.1.6. Abdominal crunches on physioball
2.1.7. Abdominal crunches on physioball with rotation
2.1.8 Bridging with head on physioball
3. Level III: weeks 4-6 - difficult strengthening exercises:
3.1. Prone bridging "around the world"
3.2. Side bridging - hip abduction, followed by flexion, followed by extension movements
3.3. Seated Russian twist with medicine ball

The supervised program (Group I) consists of three levels, each of which is 2 weeks of selected exercises, and after completion, participants proceed to the next level. Each level involves 3 sessions per week with 2 sets of 10 repetitions and 10 seconds hold. Additionally, at the beginning of each session, participants will receive conventional low back pain treatment - hot packs and TENS.

Group II will receive one training session and be provided with written materials to enable them to complete the core stability exercises at home. They will be provided with a hot pack and will be guided to use a hot water bottle at home before the session. Group II participants will be called for further assessment after 4 weeks and after completion of the 6 week program.
