Biomechanical Changes in Women With Post-partum Pelvic Girdle Pain: An Observational Case-control Study

Research suggests that changes in pelvic alignment during the perinatal period are the primary cause of pelvic girdle pain (PGP), both perinatally and postnatally. Researchers also report an association between temporomandibular joint disorder (TMD) and changes in lumbopelvic alignment. There are, however, no reports investigating temporomandibular joint disorders or changes in biomechanical alignment among women with postpartum pelvic girdle pain.

Study Overview

• Status: Completed
• Conditions: Postpartum Pain
• Intervention / Treatment: Diagnostic test: diagnostic test; Diagnostic test: Postpartum pain; Other: Visual analogue scale

Cohorts and Interventions

Group / Cohort	Intervention / Treatment
Study group (group A); Maximal vertical mouth opening (MIO): From sitting position, with the use of the calliper, the distance between the incisal edges along the midline of the upper and lower central incisors without pain was measured, by placing one end of the poley gauge against the incisal edge of one of the upper central incisors, and the other end against the incisal edge of the opposing lower incisor. The distance recorded in millimetres, the subjects was instructed to" open your mouth as wide as possible without causing pain or discomfort". The poley gauge was sterilized with antiseptic solution before and after each measure Postpartum pain Intervention 'Visual analogue scale'	Diagnostic test: diagnostic test; diagnostic test; Diagnostic test: Postpartum pain; test; Other: Visual analogue scale; test TMJ /pelvic angle/lumber angle
Control group (group B): Maximal vertical mouth opening (MIO): From sitting position, with the use of the calliper, the distance between the incisal edges along the midline of the upper and lower central incisors without pain was measured, by placing one end of the poley gauge against the incisal edge of one of the upper central incisors, and the other end against the incisal edge of the opposing lower incisor. The distance recorded in millimetres, the subjects was instructed to" open your mouth as wide as possible without causing pain or discomfort". The poley gauge was sterilized with antiseptic solution before and after each measure Postpartum pain Intervention 'Visual analogue scale'	Diagnostic test: diagnostic test; diagnostic test; Diagnostic test: Postpartum pain; test; Other: Visual analogue scale; test TMJ /pelvic angle/lumber angle

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
body mass index	BMI in kg/m^2	3 months
Pelvic tilt in degrees:	The blocks are released and the rods are placed over the crest of the ilium. The blocks are then pressed firmly toward the midline. Read the angle from the level. If the gauge reads over 21/2°, the result is listed as positive.Anterior pelvic tilting angle: PALM was used for measuring pelvic tilting angle. A mark was put on a point just inferior to ASIS; another mark was put just inferior to PSIS. The callipers of the PALM were put on these two points	3 months
jaw movement	lateral deviation mouth opening (MIO): From sitting position, with the use of the calliper, the distance between the incisal edges along the midline of the upper and lower central incisors without pain was measured, by placing one end of the poley gauge against the incisal edge of one of the upper central incisors, and the other end against the incisal edge of the opposing lower incisor. The distance recorded in millimeters, the subjects was instructed to" open your mouth as wide as possible without causing pain or discomfort". The poley gauge was sterilized with antiseptic solution before and after each measure	3 months
Spinal curves Measurement	lumber angle-pelvic inclination by mm	3 months
Satisfaction assessed by the VAS	Degrees of pain will be assessed using a VAS, which was a method of representing subjects' pain on a 10 cm linear scale. Score of 0 meant 'no pain' and 10 meant 'worst pain'. Tomeasure specific symptoms, such as the s	3 months
