Further study details as provided by University Hospital, Grenoble:

Primary Outcome Measures:
  • Delay between the detection by mechanomyography (MMG) of rectus abdominis contraction and the detection of cough in cough effort [ Time Frame: 2 hours ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Lower and upper spectral band frequencies values for which the majority of the MMG signal is present, thresholds for detection of rectus abdominis contraction by mechanical myography [ Time Frame: 2 hours ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 16

This biomedical research consists specifically in the simultaneous acquisition of:

  • EMG and MMG Signals of rectus abdominis of the abdomen,
  • Respiratory flow,
  • An electrocardiogram (ECG).

These acquisitions will be conducted on 16 healthy volunteers according to a standardized protocol, at rest and during voluntary cough and various physical exercises often resulting in urinary leakage in the incontinent person.
