Isometric Rate of Force Development, Maximum Voluntary Contraction, and Balance in Women With and Without Joint Hypermobility

Even though joint hypermobility and the benign generalized joint hypermobility (BGJH) syndrome are frequent and important phenomena in rheumatology, they have not received adequate attention and are still not sufficiently understood.

Fiche signalétique

Contexte initial

Subjects with hypermobility and normal controls were investigated concerning rate of force development and maximal voluntary contraction during single leg knee extension of the right knee were measured isometrically for each subject. Additionally balance was tested.

But

The aim was to determine if whole body vibration leads to an increased activation of normal and weakend pelvic floor muscles and if there is a difference in efficiency between sinusoidal and stochastic whole body vibration patterns.

Résultat

Hypermobile subjects showed a significantly higher value for rate of force developments. Groups did not differ significantly in MVC. In balance testing, the mediolateral sway of the hypermobile subjects showed significantly higher values.

Perspectives

In this study hypermobile women without acute symptoms were tested. It should be investigated whether hypermobile subjects with recurrent microtraumas or severe pain of the knee or ankle also show a higher rate of force development.
