A harness for attachment about a knee femur and comprised of a rigid and non- flexible frame support two resiliently mounted clamping means and sensors is described for the non-invasive measurement of knee motion and its analysis in 3-D is described. The clamping means elements are urged under pressure outwardly for application against a skin outer surface at predetermined medial and lateral sites relative to a femur. A non-resilient adjustable stabilising element is connected to the rigid frame and disposed at a predetermined location with respect to the medial clamping element in spaced relationship therewith and adjustable for clamping contact on a skin outer surface and in alignment with the centre of a medial condyle of the femur whereby to stabilise the rigid frame about a knee. An attachment rod is secured to the harness and has straps for securing the rod above the knee.

L'invention concerne une attelle à attacher autour d'un fémur, composé d'un support de cadre rigide et non flexible, deux dispositifs de fixation montés de manière souple et des détecteurs. L'attelle est destinée à la mesure non invasive des mouvements du genou et l'analyse des mesures en trois dimensions. Les éléments des dispositifs de fixation sont poussés sous pression vers l'extérieur pour une application contre une surface cutanée extérieure à des points prédéterminés médial et latéral relatifs au fémur. Un élément de stabilisation non souple est relié au cadre rigide et placé à un endroit prédéterminé par rapport à l'élément de fixation médial, espacé de ce dernier et réglable pour se fixer à une surface cutanée extérieure, en alignement avec le centre d'un condyle médial sur le fémur, afin de stabiliser le cadre rigide autour d'un genou. Une barre de fixation est fixée à la attelle et comporte des lanières pour fixer la barre au-dessus du genou.
