Effects Of A Four-Week Core Stability Exercise On Functional Movement And Balance In People With Mild Lower-Limb Discomfort

This study aimed to investigate the effects of a short-term core stability exercise on functional movement and balance in people with mild lower-limb discomfort. Twenty people with mild lower-limb discomfort were randomly assigned to control (CG) and core stability exercise training groups (SG, n=10 each). The SG completed twenty 30-min training sessions consisting of Pilates exercises for four weeks. Functional movement, balance, and discomfort level were assessed before and after core stability exercise, using a functional movement test, balance test and visual analogue scale (VAS), respectively. A mixed ANOVA with repeated measures was performed to determine the differences. SG demonstrated a significant increase in hurdle step (p = 0.024, group x time effect) and shoulder mobility (p = 0.037, group x time effect). The dynamic balance scores were significantly increased from the baseline in both limbs (right, p = 0.007; left, p = 0.011, time effect). Post-hoc pairwise comparisons indicated these increases were significant only in SG. Additionally, ankle pain was significantly reduced in SG (p = 0.023, group x time effect). This study highlights that four weeks of core stability exercise can positively affect the lower limbs' functional movement and balance in people with mild lower-limb discomfort.
