Overview

This study aims to evaluate balance and physical performance under dual task conditions in individuals with and without Generalized Joint Hypermobility (GJH), as determined by the Beighton score. All participants will undergo the One-Leg Stance Test and 30-Second Sit-to-Stand Test under both single-task (balance only) and dual-task (simultaneous cognitive task) conditions. The cognitive task will involve counting backward by sevens from a given number. Participants will also complete the Timed Up and Go (TUG) test under both single- and dual-task conditions. Additionally, the Berg Balance Scale (BBS) will be used for comprehensive balance assessment. Balance confidence will be evaluated using the Activities-specific Balance Confidence Scale (ABC-16), and fear of falling will be assessed with the Falls Efficacy Scale-International (FES-I). Changes in performance under dual-task conditions will be expressed as a percentage using the Dual Task Cost (DTC) formula

Inclusion Criteria: * Aged between 18 and 40 years * A Beighton score of 4 or higher (indicative of Generalized Joint Hypermobility) * Willingness to participate in the study Exclusion Criteria: * Younger than 18 or older than 40 years * Presence of neurological disorders (e.g., stroke, multiple sclerosis, peripheral neuropathy) * History of vestibular system disorders (e.g., benign paroxysmal positional vertigo, vestibular neuritis) * History of orthopedic conditions affecting the lower extremities (e.g., fracture, joint replacement, ligament injury) * Cognitive impairment preventing the execution of cognitive tasks * Diagnosis of systemic musculoskeletal diseases (e.g., rheumatoid arthritis, Ehlers-Danlos syndrome) * Pregnancy * Participation in balance training or neurological/physiotherapy programs within the last 6 months

Outcomes

Primary Outcomes

Performance in the One-Leg Stance Test

Assesses static balance capacity and the impact of a simultaneous cognitive task on postural control.

Time frame: 0 day

Performance in the 30-Second Sit-to-Stand Test

Evaluates lower extremity muscle endurance and functional strength under cognitive load

Time frame: 0 day

Performance in the Timed Up and Go (TUG) test

Measures dynamic balance, mobility, and the ability to maintain performance during divided attention.

Time frame: 0 day

Dual Task Cost (DTC) percentage

Quantifies the percentage change in performance when a cognitive task is added, reflecting dual-task interference.

Time frame: 0 day

Secondary Outcomes

Berg Balance Scale (BBS):

Provides a comprehensive evaluation of functional balance through various static and dynamic tasks. The maximum score is 56. Higher scores indicate that good balance.

Time frame: 0 day

Activities-specific Balance Confidence Scale (ABC-16)

Reflects the individual's perceived confidence in performing daily activities without losing balance.The maximum score is 100, the minimum score is 0. Higher scores indicate that high confidence patient's balance.

Time frame: 0 day

Falls Efficacy Scale-International (FES-I):

Assesses fear of falling during daily life activities, indicating fall-related psychological concerns. Higher scores indicate that high degree fear of falling

Time frame: 0 day
