Effects of Progressive Resistance Exercises Among Athletes With Hamstring Deficit After ACL Reconstruction

Not Applicable

Active, not recruiting

• Conditions: Sports Physical Therapy

• Registration Number: NCT06846164
• Lead Sponsor: Riphah International University

Brief Summary

The goal of the study is to find out how mild home exercises (similar to usual care) and progressive strength training, which include neuromuscular exercise, affected knee joint function and HS muscle strength in individuals who has persistent HS muscle strength deficits 12-24 months after ACLR.

Detailed Description

The objective of the present study is to investigate whether individuals, who perform supervised progressive strength training including elements of neuromuscular exercise intervention (SNG) will achieve greater improvements in leg muscle power and greater improvements in knee function compared with individuals performing a homebased low-intensity weight-bearing exercise protocol. We hypothesize that supervised progressive strength training would be superior to a homebased low-intensity weight-bearing exercise protocol for regaining muscle strength and knee function. This study will impact society by promoting health, reducing healthcare costs, supporting productivity, and contributing to a more active and engaged community. Limited investigation exists regarding the durability of progressive resistance exercises in mitigating hamstring deficits post-ACL reconstruction and the personalized optimization of exercise protocols for individual athletes. Further exploration is needed for sustained benefits and tailored rehabilitation strategies.

Inclusion Criteria

• Age between 18 - 30 years
• 12-24 months post-surgery (ACL reconstruction)
• Persistent maximal isometric knee flexor strength asymmetry (>10% leg-to-leg the difference, in the isometric testing angle of 90° knee flexion)

Primary Outcome Measures

Name	Time	Method
Limb Symmetry Index	12 weeks	It is used for knee extensors and flexors strength. It is the strength ratio between the injured and uninjured knees. It is a common method of assessing strength and functional performance after ACLR.

Secondary Outcome Measures

Name	Time	Method
H/Q ratio	12 weeks	it is used to detect muscle imbalance, monitor knee joint stability, and indicate lower extremity injury prevention and rehabilitation.
