Evaluation of Balance and Physical Performance Under Dual Task Conditions in Individuals With and Without Generalized Joint Hypermobility

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

Primary outcomes

  1. Performance in the One-Leg Stance Test

    Time frame: 0 day

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

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

    Time frame: 0 day

    Evaluates lower extremity muscle endurance and functional strength under cognitive load

  3. Performance in the Timed Up and Go (TUG) test

    Time frame: 0 day

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

  4. Dual Task Cost (DTC) percentage

    Time frame: 0 day

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

Secondary outcomes

  1. Berg Balance Scale (BBS):

    Time frame: 0 day

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

  2. Activities-specific Balance Confidence Scale (ABC-16)

    Time frame: 0 day

    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.

  3. Falls Efficacy Scale-International (FES-I):

    Time frame: 0 day

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