Effect of Photobiomodulation Therapy on Trunk Flexor Performance after Incisional Hernia Repair: A Double-Blinded, Parallel Groups, Randomized Controlled Trial

INTERVENTION: Control group C Study group A Study group B CONDITION: ; Surgery Surgery PRIMARY OUTCOME: The amount of trunk flexor muscle strength will be measured before fatigue test as 3 repetitions of isokinetic flexion‐extension movements will be executed, the greatest torque will be selected from the 3 repetitions and peak torque per bodyweight will be considered a study outcome measure. SECONDARY OUTCOME: The amount of trunk flexor fatigue resistance will be measured post fatigue test as one repetition of isokinetic flexion‐extension movement will be executed, and peak torque per bodyweight will be considered a study outcome measure. INCLUSION CRITERIA: ‐Patients had undergone postoperative (open or laparoscopic technique) midline incisional hernia repair ‐Time since operation ranged from six to twelve months ‐They ranged in age from thirty to fifty‐five years
