Association between lumbo-pelvic rhythm and dynamic balance among developmental field players of Eastern India. A Cross-sectional Study

Background

Field hockey requires lateral dominance with sustained forward flexed and asymmetrical positions, which may affect lumbo-pelvic biomechanics. Alterations in lumbo-pelvic rhythm may impact lower limb function. Although dynamic balance is considered crucial, its relationship with LPR in young hockey players is unclear.

Aim To determine the association between lumbo-pelvic rhythm and dynamic balance among developmental male field hockey player.

Method

Fourteen male field hockey players (mean age: 16.71 ± 2.27 years) participated in this pilot study. The Star Excursion Balance Test (SEBT) was used to measure dynamic balance, and 2D video analysis software KINOVEA was used to measure lumbo-pelvic rhythm in the sagittal plane during forward trunk flexion. Composite reach scores were calculated for dominant and non-dominant limbs.

The relationship between LPR and dynamic balance was examined using the Chi-square test with Phi/Cramer's V as a measure of effect size. Conclusion The results of this pilot study clearly suggest a strong association between lumbo-pelvic rhythm and dynamic balance in developmental male field hockey players.
