The effects of Q angle and Hamstring Length on Balance Performance in Patients with Lumbar Disc Hernia

Abstract

Abstract
 Aim: Patellafemoral angle (Q angle) and Hamstring length are important measurements to evaluate balance. This study aims to examine the effects of Q angle and Hamstring length on balance performance in patients with lumbar intervertebral disc herniation (LDH). 
 Material and Method: LDH (n=32) and control group (KG)(n=30) were included in the study. Q angles and hamstring muscle lengths of the participants were measured. Balance was evaluated with Y balance test.
 Results: As a result of our study, no difference was found between LDH patients and CG groups in terms of hamstring muscle length; Q angle decreased in LDH patients and there was a negative high correlation between Q angle and R -Anterior, R-Posteriomedial, R-Posteriolateral values on the right and between Q angle and L-Anterior, L-Posteriolmedial, L-Posteriolateral values on the left. 
 Conclusion: It was found that Q angle measurements decreased in LDH patients, causing genu varum and leading to impairment in balance, especially in the left anterior, anteriomedial and anteriolateral.

The Effect of Q Angle and Hamstring Length on Balance Performance in Gonarthrosis Patients

“…The shortening of the hamstring muscles makes a significant contribution to the occurrence of the G. While hamstring muscle tension increases the possibility of injury to the musculoskeletal system, it also prepares the ground for the formation of G. Along with diseases including patella femoral pain syndrome [12], patellar tendinitis [13], and lumbar disc herniation [14], short hamstrings are thought to be a major contributing factor in G. Short hamstrings can affect a person's ability to balance and their quality of life [15]. The impact of hamstring tightness on the biomechanics of G patients and how the measurement of QA, a clinical sign of G, affects people's balance in these pathologies remain unclear despite the literature's abundance of papers on the diagnosis and treatment of G patients.…”
