Could Electromyographic and Pressure Related Signals Identify Differences in Abdominal Activity and Postural Control...

Area of Science:

• Physiotherapy
• Biomechanics
• Postural Control

Background:

• Scars can affect the motor system, but the impact of caesarean section (c-section) scars on postural control is not well-understood.
• This study investigates the relationship between c-section scars and changes in neuromuscular control and stability.

Purpose of the Study:

• To determine if c-section scars are associated with alterations in postural stability and orientation.
• To assess the effect of c-section scars on abdominal and lumbar neuromuscular control in the standing position.

Main Methods:

• A cross-sectional study compared healthy women with c-section delivery (n=9) and physiological delivery (n=12) over one year postpartum.
• Evaluated electromyographic activity of abdominal and lumbar muscles, center of pressure (CoP) parameters, and spinal curvatures.
• Assessed scar mobility in the c-section group using a modified adheremeter.

Main Results:

• Significant differences were found in medial-lateral velocity and mean velocity of the center of pressure (CoP) between the groups (p < 0.050).
• No significant differences were observed in muscle activity levels, antagonist co-activation, or thoracic and lumbar curvatures (p > 0.05).

Conclusions:

• Postural impairments may be identifiable in women with c-section scars using pressure signal analysis.
• C-section scars may influence postural control, particularly concerning dynamic stability parameters.
