Lumbar Stabilization Exercises in Sedentary Adults

Официальное название

The Effect of a Lumbar Stabilization Exercise Program on Quality of Life and Motor Control in Sedentary Adults

Обзор

This pilot randomized controlled trial will examine the effects of a four-week lumbar spine stabilization exercise program on motor control, dynamic balance, and quality of life in healthy sedentary adults. Prolonged sedentary behavior has been associated with impaired neuromuscular function and increased risk of musculoskeletal disorders, even in asymptomatic individuals. Forty sedentary adults will be randomly assigned to either an intervention group, which will follow a structured lumbar stabilization exercise program, or to a control group, which will receive ergonomic and stretching guidelines. Outcomes will be assessed before and after the intervention using the SF-12v2 quality of life questionnaire, the Functional Movement Screen (FMS) and the Y-Balance Test. Physical activity levels will be monitored using the IPAQ-SF. The study aims to determine whether lumbar stabilization exercises improve health-related quality of life, motor control and dynamic balance in sedentary adults.

Подробное описание

This study will employ a two-arm parallel randomized controlled design to examine the effectiveness of a four-week lumbar stabilization intervention in sedentary adults. Participants will be randomly allocated in a 1:1 ratio to either an exercise intervention group or a control group.

To enhance measurement reliability, two baseline assessments will be conducted prior to the intervention and two post-intervention assessments will be performed after completion of the program, with a three-day interval between repeated measurements.

The stabilization program will focus on activation and progressive strengthening of the deep trunk musculature, with particular emphasis on transversus abdominis and multifidus activation. Special attention will be given to the acquisition of diaphragmatic breathing patterns to facilitate neuromuscular control. Exercises will be performed in multiple positions, including supine, side-lying, prone, and quadruped positions. The level of difficulty will be progressively increased throughout the four-week intervention period.

The control group will receive written ergonomic education and general stretching instructions without supervised exercise.

Assessments will be conducted using standardized and validated instruments to evaluate motor control, dynamic balance, and health-related quality of life. Statistical analysis will be performed using repeated-measures analysis of variance to assess within-group and between-group differences over time, with a predefined level of statistical significance set at 0.05.
