Study Electromyographic Activity of the Muscles of the Pelvic Floor Runners With Conventional Shoes and Minimalist.
Condition: Stress Urinary Incontinence
MeSH terms: Urinary Incontinence; Urinary Incontinence, Stress
Study type: Interventional

Summary: 
      JUSTIFICATION:

      Urinary incontinence is highly prevalent among women who play high impact sports such as
      running. that observed one of the possible reasons for this high prevalence is delayed
      activation of the pelvic floor in relation to the abdominal muscles.

      The use of minimalist shoes during the race produces changes in muscle and joint biomechanics
      and efficiency in the race. However, to date no studies evaluating the influence of footwear
      in the musculature of the pelvic floor during the race.

      OBJECTIVE: Describe and compare the electromyographic activity of the muscles of the pelvic
      floor and abdominal during the race with conventional shoes and minimalist.

      DESIGN: cross-over study experimental, analytical and prospective. METHODOLOGY: conventional
      and minimalist: 50 healthy young women, 6- randomly distributed in two groups will be
      included to characterise the electromyographic activity of the pelvic floor muscles before
      and during running at 6-9-11 km/h with the two types of running shoes.

      A baseline assessment will be performed to confirm that the women meet the inclusion and
      exclusion criteria. The ability to run a 10-minute treadmill at a speed of 6-9-11 km/h will
      be assessed, as well as the ability to adequately contract the pelvic floor muscles.

      The group of 50 women will initially run randomly with conventional running shoes or with
      minimalist running shoes, and then, after a 10-minute washout period, will run with the other
      type of running shoe, i.e. if a participant in the first phase used conventional running
      shoes, she will run with a minimalist running shoe in the second phase.

      The cadence of step, the range of movement of the femur and the EMG recording with
      electromyographic sensors of the pelvic floor musculature (using an intravaginal probe of the
      germproof brand), abdominal (internal and external oblique), spinal erectors and gluteus
      (using a surface sensor) in relation to the cycling gait will be collected and recorded with
      barographic sensors. The variables to be included in the electromyography for each muscle in
      relation to the gait cycle will be: onset of activation, duration, intensity and synergy with
      their corresponding standard deviation.
