About this trial
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.

Lumbar Stabilization Exercise Program
BehavioralA structured four-week lumbar stabilization exercise program targeting deep trunk musculature in healthy sedentary adults. The program will emphasize activation of the transversus abdominis, incorporation of diaphragmatic breathing, and progressive increase in exercise difficulty. Exercises will be performed under supervision in supine, prone, side-lying, and quadruped positions under structured guidance.

Trial outcomes
Primary outcomes
1
Short Form-12 Health Survey (SF-12v2) Scores
Health-related quality of life will be assessed using the SF-12v2 questionnaire. The eight domain scores (Physical Functioning, Role Physical, Bodily Pain, General Health, Vitality, Social Functioning, Role Emotional, and Mental Health) as well as the Physical Component Summary (PCS) and Mental Component Summary (MCS) scores will be calculated. Domain scores will be transformed to a 0-100 scale, with higher scores indicating better perceived health status. PCS and MCS will be computed using norm-based scoring (mean = 50, SD = 10), where higher values reflect better overall physical and mental health.

Y-Balance Test Composite Score
Dynamic balance will be assessed using the Y-balance test. The composite approach distance for each lower limb will be calculated as: (ANT + PM + PL approach distance) / (3 × limb length) × 100. The composite score is expressed as a percentage of limb length. Minimum value: 0%. Maximum value: 100% (theoretically may exceed 100% in high-performing individuals). Higher values indicate better dynamic balance. \[Time frame: Baseline and 4 weeks (after intervention)\] Asymmetry will be calculated as the absolute difference between right and left normalized reach distances (% of limb length). Minimum value: 0%. No fixed maximum value. Higher values indicate greater asymmetry.

Functional Movement Screen (FMS) Total Score
Motor control will be assessed using the Functional Movement Screen (FMS). Higher scores indicate better motor control and movement quality. The total score ranges from 0 to 21 for the 7 functional test.
