Is Pelvic Floor Dysfunction Associated With Development of Transient Low Back Pain During Prolonged Standing? A...

Area of Science:

• Musculoskeletal health
• Pelvic floor physical therapy
• Biomechanical analysis

Background:

• Prolonged standing is a workplace hazard linked to increased low back pain (LBP), particularly in women.
• Women with severe urinary incontinence experience worse LBP disability, but the role of pelvic floor dysfunction is unclear.
• Understanding the relationship between pelvic floor muscles and LBP is crucial for targeted interventions.

Purpose of the Study:

• To determine if pelvic floor and abdominal muscle co-activation patterns during prolonged standing predict transient LBP in women.
• To explore the association between stress urinary incontinence and LBP onset.
• To inform prevention and rehabilitation strategies for women experiencing LBP and/or urinary incontinence.

Main Methods:

• Prospective cohort study involving 60 women standing for 2 hours performing seated tasks.
• Electromyography (EMG) monitored pelvic floor, gluteus medius, and abdominal muscles.
• Co-activation patterns analyzed using cross-correlation; LBP assessed via numeric pain rating scale every 10 minutes.

Main Results:

• Mixed-model regression analysis will determine if muscle co-activation predicts transient LBP.
• Quantification of co-activation coefficients between muscle pairs over time.
• Assessment of LBP onset in relation to specific muscle activation and deactivation patterns.

Conclusions:

• This research aims to clarify the role of pelvic floor muscles in LBP development.
• Findings may reveal a link between pelvic floor dysfunction, stress urinary incontinence, and LBP.
• Results could guide the development of specialized programs for women's pelvic health and LBP management.
