Brief Summary

Balance and postural control are fundamental components of functional independence and quality of life in adults. Deficits in trunk stability and balance are strongly associated with increased fall risk, impaired mobility, and decreased ability to perform activities of daily living in sedentary individuals and clinical populations. Trunk muscles play a key role in stabilizing the spine and coordinating movement; their activation is essential for maintaining balance during static and dynamic tasks. Evidence suggests that targeted trunk training can significantly improve postural control and functional outcomes.

Outcome Measures

Primary Outcomes (1)

• Time Up and Go test

  Time Up and Go test will be used to evaluate dynamic balance. Participants will be asked to rise from a chair, walk 3 m to the line on the floor at a normal pace, turn around, walk back to the chair, and sit down. The time will be calculated using stopwatch. The greater the time spent to complete the test the greater the risk of impaired balance. While less time reflects good balance and mobility.

  4 weeks

Secondary Outcomes (3)

• Single leg stance test

  4 weeks

• Trunk muscle activity

  4 weeks

• Visual-Motor integration

  4 weeks

Study Arms (2)

Study group (Multitask group)

EXPERIMENTAL

Participants will receive multi-task training including strength, balance training, and visual-motor task simultaneously.

Other: Multi-task training

Control group (Single task group)

ACTIVE COMPARATOR

Participants will receive a single task including strength, balance training, and visual-motor task separately.

Other: Single task

Interventions

Multi-task training OTHER

Participants will be instructed to hold standardized handheld weight (adjusted according to individual tolerance) with both hands at chest level throughout the task to provide an additional upper-body strength component and increase trunk muscle engagement. During training, visual stimuli will be presented on a monitor positioned at eye level at approximately 1.5 m. Four geometric symbols (square, triangle, circle, and star) will be randomly displayed on the screen, each corresponding to a specific trunk movement direction.

Study group (Multitask group)

Single task OTHER

Participants will perform the same balance, strength, and cognitive components separately to eliminate task integration effects.

Control group (Single task group)

Eligibility Criteria

• Age: 18 Years - 30 Years
• Gender Eligibility Details: females will be included in this study to maintain a homogeneous sample as there is sex differences in neuromuscular control, balance performance, and hormonal influences that directly affect the study outcomes (e.g., postural stability, muscle activation, and fatigue responses).
• Healthy Volunteers: No
• Age Groups: Adult (18-64)

You may qualify if:

• Participants with low physical activity level evaluated by the Arabic version of the International Physical Activity Questionnaire-Short Form.
• Their age between 18 and 30 years.
• Body mass index less than 30 kg/ m2
• Participants who did not engage in a physiotherapy program in the previous 6 months.
• Have the ability to stand independently on balance board.
• With good cognition.
• No prior experience with dual task training.
• Absence of visual impairments, injuries or medications (such as analgesics or muscle relaxants) that may affect the results of the study.

You may not qualify if:

• Any neurological diseases (such as; severe disc prolapse and radiating pain). - History of knee injury.
• Fracture or surgery in lower extremity or the spine.
• Congenital deformity.
• Orthopedic disorders such as patellofemoral pain syndrome.
• Vestibular disorders or severe balance impairment.
• Psychiatric problem.
• Any systemic disease.
• Cardiovascular complications.
• Pregnancy.
