MRC score requires cooperation of patient, does not distinguish between myopathy / neuropathy
Mostly non-volitional testing for pts who cannot cooperate; some differentiation between myopathy / neuropathy; direct muscle stimulation is NOT common in clinical practice
*Obesity is the only protective non-modifiable factor for weakness!
Modifiable risk factors that can be addressed: Avoid hyperglycaemia, avoid early Parenteral nutrition, aim to mobilise early
Short-term consequences include: ICU / hospital mortality, longer duration mech ventilation, extubation failure, swallowing disorders etc.
Long-term consequences include: post-ICU mortality, non-discharge to home, longer period of rehab, impaired functioning
Long term survival decreases with increasing severity of weakness
Longer ICU stay –> worsening weakness
