<![CDATA[Background: Muscle length is defined as the length at which the maximum amount of force a muscle isable to produce. This length is determined by the joint angle corresponding to that muscle. Understandingthe optimal muscle length as well as its comparison between the extremities is very important as a partof examination in physiotherapy, particularly in the cases of musculoskeletal disorders. Several tests areavailable for testing the muscle length. However standardize and reliable tests have been chosen to preventthe error while testing. Many studies have shown that there was difference in the lengths of muscle of lowerextremity which was assessed in different players. However there is paucity of study on the muscle lengthof individuals who are completely normal and not the athletes.Objectives: The objective of this study is comparison between the length of iliopsoas, hamstring,gastrocnemius, rectus femoris in dominant to non-dominant extremity in young asymptomatic individualsaged between 18-25 years.Methods: Measurement of hamstring, iliopsoas, rectus femoris and gastrocnemius length will be acquiredthrough standard goniometer. The methods of assessment that will be used are; active knee extension (AKE)tests the hamstrings, Thomas and modified Thomas test to evaluate iliopsoas and rectus femoris while prone,figure-four position accompanied by dorsiflexion for gastrocnemius.Results: Once the study is completed, the parameters of outcome measure will be statistically analyzed andcalculated.Conclusion: Based on the previous data we assume that there can be a significant difference between themuscle lengths of lower limb in normal person.]]>
