Y1 - 2017 N1 - T2 - Principles and Practice of Hospital Medicine, 2e AB - Key Clinical Questions Is the onset of weakness abrupt/acute, gradual/subacute, or insidious/chronic? Is the weakness stable, progressively worsening, waxing and waning, or fatigable? Is the weakness symmetric or lateralized? Is the weakness length-dependent? Are the involved muscles all weak to the same degree? If a gradient of weakness exists, is it worse proximally or distally? Are specific muscles or groups of muscles weak?
