Eccentric-concentric and concentric eccentric moods were used for hamstring and quadriceps respectively at angular velocity of 60\u00b0\/s.<\/p>\n<p style=\"text-align: justify;\"><strong>Results:<\/strong> 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 \u02c2.05].<\/p>\n<p style=\"text-align: justify;\"><strong>Conclusion<\/strong>; 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.<\/p>\n<p style=\"text-align: justify;\"><strong>Key words<\/strong>: Muscular Torque, H\/Q Ratio, Hypermobility.<\/p>\n<p style=\"text-align: justify;\"><strong>REFERENCES<\/strong><\/p>\n<ol style=\"text-align: justify;\">\n<li>Coombs, Rosalind, and Gerard Garbutt.
