Post-polio syndrome physical examination

PPS may be difficult to diagnose in some because it is hard to determine what component of a neuromuscular deficit is old and what is new: Neurological examination aided by other laboratory studies can help to exclude all other possible diagnoses. Objective assessment of muscle strength in PPS patients may not be easy. Changes in muscle strength are determined in specific muscle groups sing various muscle scales which quantify strength, such as the Medical Research Council (MRC) scale.
