Research summary
Knee instability can be a limiting condition and a consequence of some pathologies and knee injuries. Knee instability is typically characterised by excessive joint laxity (looseness) and atypical muscular activity. Individuals with joint hypermobility syndrome often report knee instability, due to the excessive joint laxity. Injuries of the Anterior Cruciate Ligament (ACL) are another condition that may lead to knee instability due to the rupture of the principal restraint to excessive anterior tibial translation (major shank bone). Knee instability is a limiting condition and can lead to reducing activities of daily living to avoid episodes of knee buckling or giving way.
Currently there is little research on how to assess knee instability; therefore, the aim of this study is to develop computational tools to evaluate knee instability in those with joint hypermobility or with an ACL injury. A cross sectional study will be conducted in the Glasgow Caledonian University human performance laboratory. A sample of 22 female patients with ACL tear, a maximum of 44 female patients with joint hypermobility syndrome and 22 age and gender-matched controls will be recruited.
Measures of lower limb muscular activity, forces, knee acceleration and joints motion will be recorded during activities of the daily living (stand, walk, ascend and descend a ramp and stairs). The side-to-side and back-to-front knee laxity will be assessed during the lab section as the ability to detect motion and position of the knee. Self-reported knee pain, instability, and participants’ level of fatigue will also be recorded using questionnaires.REC name
