Plain English summary of protocol

It is assumed that in some patients with pain in the pelvic area, the dorsal joints of the pelvis may be mis-aligned. Due to this mis-aligment some specific ligaments become overstretched and painfull. Pressure on this painful ligament produces pain in a specific area. This procedure is called: the long dorsal ligament (LDL) test. Thus, when positive, this test is an indication of mis-alignment of the pelvic joint.
For patients with pain in the pelvic area there are exercises that are believed to relieve pain because they reposition the pelvic joints. It is unclear whether these exercises really can be effective. This study investigates whether these self-mobilization exercises are effective in correcting sacro-iliac
joint position. For this study patients that apply for treatment in our centre are asked to perform either the specific mobilisating exercise or a sham exercise. If the mobilization is effective the LDL test should be less painful.

Study information

Primary study design	Interventional
Study design	Randomized controlled trial
Secondary study design	Randomised controlled trial
Study type	Participant information sheet
Scientific title	The effect of self-mobilizing exercises for correction of counternutated Sacro-iliac joints in pelvic girdle pain patients
Study objectives	Self-mobilization exercises are effective in correcting sacro-iliac joint position
Ethics approval(s)	The study was initiated in 2012 (Q4). At that time ethics approval was not required. Study results were presented at a conference. Since it not our primary activity (we are a rehab centre) it took us a long time to convert the study results to a manuscript.
Health condition(s) or problem(s) studied	Chronic pelvic girdle pain
Intervention	Patients were randomized by pulling a lot from a bag. Intervention: patients performed a self-mobilisation exercise according to the exercise described by Richard DonTigny. Control group: patients performed from a similar posture to the intervention group a mobilisation in opposite direction. Both groups made 3 repetitions of 5 seconds for the exercise.
Intervention type	Behavioural
Primary outcome measure(s)	1. LDL test (pain provocation of long dorsal sacroiliac ligament) tested before and after each treatment. 2. Pain score visual analogue score before and after each treatment.
Key secondary outcome measure(s)	N/A
Completion date	15/06/2013
