Hamstring Flexibility in Adolescent with or Without Plantar Flexion- A Narrative Review.

Abstract

Background: Flexibility is a property of the muscle to be lengthened to achieve required range of motion. Hamstring muscle constitutes posterior compartment of thigh, which consists of semimembranosus and semitendinosus, biceps femoris, and primarily response for knee flexion. As the age progress, there is physiological shortening of hamstring muscle due to various reasons. Objectives: Is to review the literature for hamstring flexibility measurement in relation to plantar flexors in adolescent between 12 to 19 years. Methods: The analysis of literature was done through Google Scholar, PUBMED, and EMBASE MEDLINE. The review period is from 2016 to 2021 which includes articles of full text English originated. Results and conclusion: In search of article we found 50 articles out of it there were 14 articles which describe about the assessment of hamstring flexibility. There are different assessment tool were used to find the hamstring flexibility. However, there is limited literature associated to hamstring flexibility with or without plantar flexion. There is dearth of literature review on the adolescent for hamstring flexibility, positive review of comparison of study between plantar flexion and neutral position, back saver sit and reach test is more comfortable test than other test. In addition to it adapted sit & reach box has absolute validity & reliability and there is negative correlation between thoracic spine and hip component for the same. Keywords: Hamstring Flexibility, Sit and Reach box (SRT), Back Saver sit and Reach box test (BSRT) and Chair Sit and Reach Test (CSRT).
