Grading The severity of<unk>  can be classified into different "grades" based on the following criteria: * Grade 0: No contraction or muscle movement. * Grade 1: Trace of contraction, but no movement at the joint. * Grade 2: Movement at the joint with gravity eliminated. * Grade 3: Movement against gravity, but not against added resistance. * Grade 4: Movement against external resistance with less strength than usual. * Grade 5: Normal strength. Classification Proximal and distal<unk>  can also be classified as either "proximal" or "distal" based on the location of the muscles that it affects. Proximal<unk>  affects muscles closest to the body's midline, while distal<unk>  affects muscles further out on the limbs. Proximal<unk>  can be seen in Cushing's syndrome and hyperthyroidism. True and perceived<unk>  can be classified as either "true" or "perceived" based on its cause. * True<unk>  (or neuromuscular<unk>  describes a condition where the force exerted by the muscles is less than would be expected, for example muscular dystrophy. * Perceived<unk>  (or non-neuromuscular<unk>  describes a condition where a person feels more effort than normal is required to exert a given amount of force but actual muscle strength is normal, for example chronic fatigue syndrome. In some conditions, such as myasthenia gravis, muscle strength is normal when resting, but true<unk>  occurs after the muscle has been subjected to exercise. This is also true for some cases of chronic fatigue syndrome, where objective post-exertion<unk>  with delayed recovery time has been measured and is a feature of some of the published definitions.
