6. MSK 3 Pelvic girdle, Lumbago, Hip Pain Flashcards
What is the association between relaxin levels and pregnancy-related pelvic girdle pain (PPGP)?
The association between PPGP and relaxin levels was found to be low.
What roles and which pelvic ligaments play in pelvic stabilization?
Pelvic ligaments, such as the long dorsal, iliolumbar, and sacrotuberous, prevent excessive nutation and counternutation.
Sacrospinous an dtuberous help provide proprioceptive feedback
Which active structures contribute to pelvic stabilization?
Active structures include gluteus maximus, erector spinae, biceps femoris, and thoracolumbar fascia.
What is relaxin?
Relaxin is a peptide hormone of the insulin-like growth factor family.
When is relaxin secreted during pregnancy?
Relaxin is secreted from the corpus luteum and placenta from early pregnancy.
Hormone reaches considerable level during first trimester
What happens to relaxin levels during pregnancy?
Relaxin levels increase considerably during the first trimester and remain steady until late pregnancy.
When does relaxation of pelvic ligaments begin during pregnancy?
Relaxation of the pelvic ligaments begins at the tenth to twelfth week of pregnancy.
What were the findings regarding relaxin levels and PPGP in studies?
Four out of six studies (66%) did not find an association between levels of relaxin and PPGP.
What should be ruled out when classifying PPGP?
Low back or gynaecological symptoms should be ruled out.
What are the strongest risk factors for newly developed PPGP?
Prior histories of low back pain (LBP) or PPGP and strenuous work.
What is important in study selection for PPGP?
Controlling PPGP risk factors is important in study selection.
What is needed for future research on PPGP?
Future research should standardize assessment procedures for PPGP and uniformly control for stress and a history of LBP and PPGP in study design.
What consensus components were reached for the management of pregnancy related pelvic girdle pain according to the Aldabe 2022 study

What is the impact of nonspecific LBP on postural control?
It affects anticipatory activation of deep muscles controlling lumbopelvic stability.
What does stronger anticipatory postural adjustment (APA) responses in lumbar spine muscles indicate?
It is associated with increased body sway and greater amplitude in center of pressure.
How does pain affect muscle activation during postural control?
Pain may cause a delay in activation of deep muscles.
Which muscles exhibit anticipatory changes in activation for individuals with pelvic girdle pain (PGP)?
Biceps femoris and gluteus maximus.
What were the findings regarding APA duration in the control group compared to pain groups?
Control group had longer APA duration than pain groups.
What were the differences in COP amplitudes between the control and pain groups?
Control group had higher COP amplitudes than pain groups.

Pain groups had longer muscle onset latency in external oblique and gluteus maximus.
Which group (PG pain or control ) exhibited further delays in muscle onset latency compared to controls?
The PGP group.
How did visual feedback (eyes open vs. eyes closed) affect APA duration within PG pain group and control?
All groups had increased APA duration with eyes closed, but only the control group was significant.
What was the significance of COP (ML) amplitude with eyes closed for the control group?
There was a significant increase in COP (ML) amplitude.
What was observed in the PGP group regarding COP (ML) amplitude with eyes closed?
There was a decrease in COP (ML) amplitude, but not statistically significant.

Biceps femoris, external oblique, and multifidus in eyes closed; internal oblique in eyes open.
What were the overall differences in APA duration and COP amplitudes between pain groups and the control group?
Pain groups had shorter APA duration, lower COP amplitudes, and greater muscle onset delays.
What factors contribute to lower COP amplitude in pain patients?
Pain interfering with motor control, limiting velocity, force, and range of motion, as well as fear of movement.
What may cause sacroiliac joint instability and lead to LBP?
Mal-recruitment of glutes and hamstrings.
Which muscles are associated with global anticipatory postural control?
Transversus abdominis (TA) and internal oblique.
How is muscle activation latency scaled in relation to postural threat?
Latency is earlier with larger postural threats.
What is pelvic girdle pain (PGP)?
PGP is located under the PSIS, in the gluteals area, posterior thigh, and groin, specifically over the pubic symphysis. Pain may radiate in the posterior thigh.
List the risk factors for pelvic girdle pain.
- Prior history of pregnancy
- Orthopedic dysfunctions

What are the two mechanisms for stabilization of the pelvis during load transfer?
- Form closure
- Force closure
At what gestational weeks does symphysis widening begin and what is the average width at full term?
Symphysis widening occurs as early as 8 to 10 weeks and increases to an average width of 7 mm at full term.

What was the overall quality of evidence regarding prenatal exercise and its effect on LBP, PGP, and LBPP during pregnancy?
‘Very low’ to ‘moderate’ quality evidence
Evidence was derived from a study involving 52,297 women.
Did prenatal exercise reduce the odds of LBP, PGP, or LBPP during pregnancy according to the systematic review?
No, it did not reduce the odds
This conclusion was based on various types of prenatal exercise including aerobic, yoga, and strengthening exercises.
What type of evidence supports the effectiveness of prenatal exercise in decreasing the severity of LBP, PGP, and LBPP during pregnancy?
‘Very low’ to ‘moderate’ quality evidence
This suggests that while the odds were not reduced, the severity of pain was alleviated.

Exercise decreased the severity of LBP in the postpartum period
This finding was based on low-quality evidence.

85% greater likelihood
This highlights the importance of managing symptoms early.
How may exercise serve as a strategy for expecting mothers regarding pain management?
Cost effective, self-management strategy
It should be part of a multimodal approach to decrease symptom severity.
What are some proposed mechanisms through which exercise may reduce pain severity during pregnancy?
- Lessens degree of biomechanical change
- Decreases load on the spine
- Increases joint stabilisation
- Contributes to better spinal alignment and segmental motion
These mechanisms highlight the physiological benefits of exercise.
What potential effect does exercise have on trunk muscle balance during pregnancy?
Helps reverse trunk muscle imbalance
This could lead to improved functional stability.
What conclusion was drawn regarding the effectiveness of exercise initiated during pregnancy on the prevalence of LBP, PGP, or LBPP?
