Effect of Corrective Exercises with a New Approach on the Isometric Strength in People ‎with Pronation Distortion Syndrome

Pronation distortion syndrome is one of the most common abnormalities in the body that causes distortions in the structures parts of the lumbar-pelvic and lower limb. The purpose of this study was to determine the effect of corrective exercises with a new approach on the isometric strength of the lower body muscles in people with pronation distortion syndrome.

In this semi experimental research, 30 volunteers who had pronation distortion syndrome were selected and randomly divided into two groups of control (Mean±standard deviation, age: 12.6±1.8 year, height: 166.4±9.6 cm, body mass: 68.6±9.9 kg, body mass index: 24.7±2.2 kg/m2) and experimental (Mean±standard deviation, age: 12.6±1.7 year, height: 165.3±6.6 cm, body weight: 67.1±5.7 kg, body mass index: 24.55±1.6 kg/m2). Experimental group, performed corrective exercises with a new approach for 12 weeks (3 sessions per week for one hour), but control group performed the routine and normal exercise. Before and after 12 weeks performing exercises, the isometric strength of the lower body muscles (digital dynamometer) were evaluated. For data analysis, repeated measures ANOVA with Bonferroni post hoc test at 5% error level was used (p < 0.05).

The experimental group after 12 weeks of corrective exercises with a new approach showed significant improvements in the isometric strength of the lower body muscles (p < 0.001), But in control group there was no significant difference (p>0.05). In addition, after the intervention, the isometric strength of the lower trunk muscles was significantly higher in the experimental group (p < 0.001), but this difference was not significant in the pre-test (p >0.05).

It seems that corrective exercises with a new approach improve isometric strength of the lower body muscles in people with pronation distortion syndrome, so it is recommended for these people.
