Isokinetic evaluation of knee extensor/Xexor muscle strength
in patients with hypermobility syndrome

Benign joint hypermobility syndrome (BJHS)
is a syndrome with musculoskeletal pain originating from
the increased laxity of the joints and the ligaments. The
study was to compare the isokinetic strength of knee extensor/
Xexor muscles of BJHS patients with healthy controls.
Forty patients diagnosed as having BJHS with Brighton criteria
and 45 years of age, height and weight-matched
healthy controls were recruited for the study. Isokinetic
testing was performed with isokinetic dynamometry of Biodex
System 3Pro and measurements were recorded at knee
extension/Xexion pattern concentrically at 60, 180, and
240°/s angular velocities. The study group was also evaluated
for functional impairment and pain by HAQ and VAS
respectively. Knee extensor muscle strength was signiWcantly
lower in the patient group compared with the controls.
It was hypothesized that the muscle weakness in the
study group was related to lengthening of the quadriceps
muscle and pain-related inactivity as well as joint instability
and proprioception defect.
