# Motor Control Exercises and Their Design for Short-Term Pain Modulation in Patients with Pelvic Girdle Pain: A Narrative Review

## TL;DR

This review examines motor control exercises for short-term pain relief in pelvic girdle pain patients, finding limited evidence of their effectiveness due to inconsistent design.

## Contribution

The paper evaluates how motor control exercises are designed for pelvic girdle pain and whether they align with motor control theories.

## Key findings

- Most studies did not show significant pain reduction from motor control exercises.
- Exercises were often not structured according to motor control principles.
- Only one study demonstrated statistically significant pain improvement.

## Abstract

Background: Pelvic girdle pain (PGP) is described in the literature as a subgroup of low back pain (LBP), characterized by pain localized between the posterior iliac crest and the gluteal fold, particularly near the sacroiliac joints. This condition can manifest in different forms non-specific PGP, occurring during pregnancy or postpartum (pregnancy-related PGP), which represents the most prevalent form and non-pregnancy-related PGP, resulting from mechanical alterations caused by trauma or microtrauma. Specific PGP, associated with identifiable causes such as fractures, infections, or arthritis. Over the years, research has focused on identifying the most effective approaches for managing this condition and addressing its associated biopsychosocial impairments. The aim of this narrative review is to determine the types of motor control exercises (MCEs) used to reduce short-term pain in patients with PGP and to assess whether these exercises are designed in accordance with the principles of motor control (MC) theories. Methods: A narrative review was conducted through searches in various medical and rehabilitation databases, including MEDLINE (via PubMed), PEDro, Scopus, and Web of Science. The inclusion criteria of the review encompassed case studies, case reports, editorials, original research articles, randomized controlled trials (RCTs), and systematic reviews (SRs). Results: Six articles met the eligibility criteria, comprising two SRs and four RCTs, all of which were included in the qualitative analysis. Among these, two studies examine MCEs for non-pregnancy-related PGP, while all the other studies focus on pregnancy-related PGP. The exercises described focused on lumbar–pelvic stabilization or deep spinal muscle activation. Among the six included studies, five did not report statistically significant changes in pain outcomes, while only one study demonstrated a statistically significant improvement. Conclusions: The analysis highlighted that the exercises currently employed are generally unspecific and not systematically structured according to the principles outlined in MC theories. The available evidence, combined with the incorrect design of these exercises, does not allow for definitive conclusions regarding the efficacy of MCEs in reducing short-term pain in patients with both pregnancy-related and non-pregnancy-related PGP.
