| description | Introduction: Reduction in abdominal muscle’s strength has
been implicated in the development of inguinal hernia. Patients
with inguinal hernia on one side are shown to be at higher risk
of developing inguinal hernia on the other side.
Aim: To assess the abdominal muscle strength in inguinal hernia
subjects using surface Electromyography (EMG) and compare it
with healthy controls.
Materials and Methods: This is a cross-sectional study
involving only male subjects. Abdominal (Inguinal) hernia
subjects without any known complications were recruited from
surgery department and the accompanying healthy individuals
were taken as control (Control, n=44, inguinal hernia subjects,
n=43). The subjects were asked to perform maximal contraction
for three seconds targeting external and internal oblique muscles
of right and left sides separately. Motor unit potentials were
recorded using surface EMG for individual muscles on both
sides during maximal contraction. The maximum amplitude
of the motor unit potentials obtained was considered as the
strength of the respective muscle.
Results: In control group, there was no significant difference in
strength of external and internal oblique muscles between the
two sides. Strength of external and internal oblique muscles
of both herniated and unaffected side was reduced in inguinal
hernia subjects as compared to healthy controls. Further, the
muscle strength of herniated side was less as compared to
unaffected side in the inguinal hernia subjects.
Conclusion: Abdominal muscle strength is reduced in hernia
subjects and even the apparently normal side strength is less
as compared to controls. This should be considered while
performing corrective surgeries in inguinal hernia subjects. |
