To assess the relation between joint mobility and genital prolapse, joint mobility in 76 women with genital prolapse was compared with that in an age and parity matched control group without prolapse. Mobility was scored on a scale of 0-9. The number of patients with hypermobile joints and the total mobility scores were higher in the genital prolapse group (p less than 0.005), which also had more joint complaints and twice the prevalence of backache when compared with the control group.
