Effect of Inguinal Hernia Repair on Isokinetic Muscle Strength

Study Overview
=================
Brief Summary
-----------------
The aim of the present prospective controlled study is to compare the trunk muscle strength, quality of life and neuropathic pain component after Lichtenstein and Kugel procedures.

Detailed Description
-----------------
In this study patients underwent inguinal hernia repair will be evaluated for the effect of the surgical procedure on abdominal muscle strength.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| isokinetic muscle strength | Trunk muscle strength measurement using the Biodex System 3Pro Multi-joint System Isokinetic dynamometer. Peak torque (PT) and PT-based agonist/antagonist ratios will be used to reveal strength imbalances. | 6 - 12 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| quality of life assesment | Quality of life assesment will be performed by Short Form 36 (SF-36) and The PainDETECT questionnaires (PD-Q). | 6 -12 months |
