Abstract
AbstractBackground: Increased anterior pelvic tilt is one important contributor to poor posture in children and adolescents and caused by muscular imbalance. This study aims at identifying the extent to which a sensorimotor training reduces anterior pelvic tilt more effectively than pure strength and stretch training alone. Methods: 54 male adolescents (age 13–17) with an increased pelvic tilt angle >14° were matched to three groups (strength training STR, strength + sensorimotor training STR + SENS, control CON). Maximum isometric torques for knee flexion (HA), trunk flexion (RA), and trunk extension, and pelvic tilt were measured before and after a 12 week physical therapy schedule. Two-way mixed ANOVA were calculated. Results: For STR and STR + SENS the relative torque of HA and RA increased significantly (p < 0.05) between pre- and post-test. Significant improvement of the pelvic tilt angle was identified in both training groups, with STR + SENS exhibiting a significantly larger degree of improvement....
Highlights
Between 22 and 65% of children and adolescents demonstrate poor posture (Bogdanović & Marković, 2010; Gh, Alilou, Ghafurinia, & Fereydounnia, 2012; Kopecký, 2004)
We examined whether targeted gym training of specific muscle groups can help improve posture in adolescents
Intervention effect “strength of the rectus abdominis RA” The factor measurement time became significant with major effect size (F = 18.64; p < 0.0001; η2 = 0.27)
Summary
Between 22 and 65% of children and adolescents demonstrate poor posture (Bogdanović & Marković, 2010; Gh, Alilou, Ghafurinia, & Fereydounnia, 2012; Kopecký, 2004). An increased anterior pelvic tilt is one key cause of hyperlordosis of the lumbar spine and a posture-constituting characteristic of therapeutic importance (Le Huec, Aunoble, Philippe, & Nicolas, 2011; Roussouly & Pinheiro-Franco, 2011). Earlier studies proved that targeted strength programs for the muscle groups that reduce pelvic tilt resulted in an improvement of posture in adolescents with increased anterior pelvic tilt (Klee, 1994). Increased anterior pelvic tilt is one important contributor to poor posture in children and adolescents and caused by muscular imbalance. This study aims at identifying the extent to which a sensorimotor training reduces anterior pelvic tilt more effectively than pure strength and stretch training alone. Conclusions: Sensorimotor exercises improve the effectiveness of physical fitness training to reduce anterior pelvic tilt and should supplement existing therapeutic programs
