ABSTRACT

Purpose: the current study intended to investigate the effect of hypermobility on the hamstring’s muscular torque, quadriceps’ muscular torque and H/Q ratio.

Materials and Methods: thirty normal male children aged from seven to eleven years and thirty age-matched male children with GJH were tested using isokinetic dynamometer. Eccentric-concentric and concentric eccentric moods were used for hamstring and quadriceps respectively at angular velocity of 60°/s.

Results: the results exposed that there was significant decrease in both peak muscular torques and H/Q ratio in children with GJH when they were compared with normal children [P ˂.05].

Conclusion; it can be concluded that joint hypermobility decreases muscular torque and H/Q ratio. This may be due to proprioceptive deficits associated with hypermobility and abnormal muscular activation pattern. Further studies are needed to verify the definite cause of decreased muscular torque and H/Q ratio.

Key words: Muscular Torque, H/Q Ratio, Hypermobility.
