This nerve damage can cause loss of sensation or numbness or tingling known as neuritis in areas of the body supplied by the nerve. Over-exertion can cause increased pressure in a muscle resulting in oedema or scar tissue formation, which results in impaired nerve function. Impaired nerve function, destruction of fibres or damage resulting in reduced nerve
conduction velocity may cause muscle weakness. Holding joints in an awkward posture for long
hours is an unavoidable state of affairs in agriculture, household or animal care jobs and is a
big reason for increase in probable episodes of these problems. ‘The ability of the muscles to protect the joints against external forces is degraded and the joint itself is more easily damaged when the limb is exposed to high forces’
(Bridger 2008).
