Kress and Hall (April 24 issue)1 describe neuromuscular problems commonly observed in the intensive care unit (ICU) during critical illness. Critical illness polyneuropathy is a generalized axonal neuropathy with predominance in the lower extremities.2 Entrapment neuropathy is also quite common in the ICU. Loss of subcutaneous fat during a long stay in the ICU makes peripheral nerves susceptible to compression injury, particularly at the fibular head (leading to diminished power of the anterior tibialias) and at the ulnar groove (leading to diminished power in the intrinsic hand muscles). The problem can be avoided simply by awareness and proper limb positionin
