A resilient brace (7) has first and second attachment portions (9, 11) formed at either end and a resilient portion (13) located therebetween, the resilient portion comprising a plurality of planar sections (15) orientated in a corrugated manner. The attachment portions lie on the same plane on which a stress axis is also located. The planar sections (15) are angled relative to one another and to the attachment portions so that each planar section (15) extends laterally of the stress axis.
