Why the study?
Is benign hypermobile joint syndrome associated with an increased occurrence of mitral valve prolapse or systemic connective tissue disorder characteristics?
Is benign hypermobile joint syndrome associated with an increased occurrence of mitral valve prolapse or systemic connective tissue disorder characteristics?
Benign hypermobile joint syndrome appears to be a normal variant of joint motion rather than a systemic connective tissue disorder associated with mitral valve prolapse.
May reassure against routine MVP screening in benign hypermobility; leaves open distinction from rarer connective tissue disorders.
Benign hypermobility as defined by a modification of the Carter-Wilkinson criteria was found in 31 of 637 healthy blood donors, a prevalence of 5%. No increased prevalence of arthritis/arthralgia or characteristics suggestive of Ehlers-Danlos syndrome other than a possible familial predisposition were found when these 31 hypermobile subjects were compared to an age and sex matched two-for-one control group. Cardiac evaluation by auscultation, electrocardiogram, and echocardiogram showed no increased occurrence of mitral valve prolapse in hypermobile subjects. Thus the benign hypermobile joint syndrome appears to be one extreme of the range of normal joint motion and not a systemic connective tissue disorder.
