The functional consequences of generalized joint hypermobility: a cross-sectional study

Area of Science:

• Physiology
• Biomechanics
• Sports Science

Background:

• Generalized Joint Hypermobility (GJH) is associated with musculoskeletal issues and disability.
• GJH is sometimes considered a prerequisite for success in sports like dance.
• The precise role of GJH in human performance remains unclear.

Purpose of the Study:

• To determine the association between GJH and functional status.
• To investigate the influence of physical fitness and musculoskeletal complaints on this association.

Main Methods:

• 72 female students (mean age 19.6) from health professions and arts schools were recruited.
• Data collected included functional status (physical activity, walking distance, jumping capacity), GJH (Beighton score ≥4), muscle strength, and musculoskeletal complaints (pain, fatigue).
• Demographic data (age, BMI) were also recorded.

Main Results:

• GJH was negatively associated with all functional status capacity measures.
• Participants with GJH exhibited reduced walking distance and jumping capacity (side hop, square hop) compared to those without GJH, even after controlling for confounders.
• In participants with GJH, functional status was not associated with performance measures.

Conclusions:

• GJH is independently linked to lower walking and jumping capacity, possibly due to compromised connective tissue integrity.
• Pain, fatigue, and muscle strength were identified as significant contributors to functional status.
• Further research may explore interventions to mitigate functional limitations in individuals with GJH.
