Screening edit Initial screening for CIP/CIM may be performed using an objective scoring system for muscle strength.

"Validation of the peroneal nerve test to diagnose critical illness polyneuropathy and myopathy in the intensive care unit: the multicentre Italian crimyne-2 diagnostic accuracy study".A b c Latronico N; Fenzi F; Recupero norton ghost 2003 cracked D;.3, corticosteroids and neuromuscular blocking agents, which are widely used in intensive care, may contribute to the development of CIP and CIM, 4 as may elevations in blood sugar, which frequently occur in critically ill patients.Hermans G; Wilmer A; Meersseman W;.CIP and CIM have similar symptoms and presentations and are often distinguished largely on the basis of specialized electrophysiologic testing or muscle and nerve biopsy.Guarneri B; Bertolini G; Latronico N (2008).
The MRC score involves assessing strength in 3 muscle groups in the right and left sides of both the upper and lower extremities.
11 With critical illness myopathy, no other cause of the muscle degeneration can be found.
11 The use of conventional nerve conduction studies is time consuming and requires specialized personnel; however, simplified electrophysiologic tests can be used as screening tools in the critically ill to confirm or exclude CIP/CIM.Each muscle tested is given a score of 0-5, giving a total possible score.If a lumbar puncture (spinal tap) is performed, the protein level in the cerebral spinal fluid would be normal.Fan E; Cheek F; Chlan L;.9 In the six sigma handbook fourth edition pdf 1996, Latronico and colleagues first described that CIP and CIM often coexist in the same patient.Unlike Guillain Barre Syndrome, another neurological disorder that causes weakness, patients with critical illness polyneuropathy do not have loss of the myelin sheath that normally surrounds neurons ( demyelination ).Such risk factors include: multi-organ dysfunction, renal failure, renal replacement therapy, duration of organ dysfunction, duration of ICU stay, low albumin, and central neurologic failure.A greater severity of illness increases the risk of CIP/CIM."The sick and the weak: neuropathies/myopathies in the critically ill".9 More exact data is difficult to obtain, since variation exists in defining the condition."Acute neuromuscular weakness in the intensive care unit".
