Purpose:
The aim of this study was to investigate whether muscle strength and functional exercise capacity (FEC) influence motor performance in children with generalized joint hypermobility.
Methods:
Forty-one children (mean age: 8.1 years) with symptomatic generalized hypermobility were included. Motor performance was assessed using the Körperkoordinationstest für Kinder (KTK) and the Movement Assessment Battery for Children. Muscle strength and FEC were measured with a handheld dynamometer and the 6-minute walk test.
Results:
Only muscle strength was significantly positively associated with motor performance on the KTK. FEC was significantly decreased. Children's scores on the KTK were significantly lower (p < 0.001) compared with scores on the Movement Assessment Battery for Children.
Conclusions:
The KTK is a more sensitive tool for detecting motor problems in children with generalized joint hypermobility, but is not associated with FEC. Along with the KTK, the 6-minute walk test can be used to independently assess and evaluate FEC.

Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

Exercise and Muscle Performance
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...
