About this trial
This three-arm, parallel-group, randomized controlled trial (RCT) investigates whether dual-task therapeutic exercises (dynamic balance + cognitive task) improve perceived stress and dynamic balance in 72 healthy university students (18-25 years) compared to traditional balance training alone or a control group receiving general health advice. The dual-task group performs the same dynamic balance exercises (e.g., backward walking, tandem gait, single-leg reaches) while simultaneously engaging in cognitive tasks (verbal fluency, arithmetic, or working memory). The intervention lasts 6 weeks (2 sessions/week, 20-30 min each). Primary outcomes are Perceived Stress Scale (PSS-10) scores and objective dynamic balance indices (anterior/posterior/lateral deviation, overall stability) measured via the Balance check 636 device. Assessments occur at baseline and post-intervention by a blinded assessor. The study addresses a gap: no prior trial has examined combined effects of dual-task training on both stress modulation and balance in this population.

Treatments tested in this trial
Dynamic Balance Training Only
Other interventionParticipants perform a structured set of dynamic balance exercises under single-task conditions (motor task only). Exercises include: 1. Controlled Backward Walking (CBW): Walk backward in a straight line (5-10 meters) using a toe-heel strike pattern; maintain upright trunk, head forward, arms naturally at sides. 2. Controlled Lateral Dynamic Stepping (CLDS): Step sideways along a 5-meter path; feet shoulder-width apart, knees slightly flexed, hands clasped at chest; gaze fixed forward. 3. Single-Leg Forward Reach (SLFR): Stand on one limb, hands crossed over chest; reach the non-standing leg forward to touch the floor with toes, return without losing balance. 10 repetitions per leg. 4. Single-Leg Lateral Reach (SLSR): Same as SLFR but reaching sideways (lateral abduction). 10 repetitions per leg. 5. Dynamic Tandem Gait (DTG): Walk heel-to-toe in a straight line (3-5 meters) with hands crossed over chest; gaze fixed forward. Delivery: In-person, supervised by a trained physical thera

PERCEIVED SRESS SCALE
The Perceived Stress Scale (PSS-10) is a 10-item self-report questionnaire designed to measure the degree to which situations in one's life over the past month are appraised as stressful. Items assess feelings of unpredictability, uncontrollability, and overload (e.g., "How often have you felt nervous and stressed?"). Responses are rated on a 5-point Likert scale from 0 (never) to 4 (very often). Total scores range from 0 to 40, with higher scores indicating higher perceived stress.
