Sammanfattning

New or increased symptoms often appear decades after the onset of polio. The definition of post polio syndrome (PPS) is: a confirmed history of polio, an interval of functional stabi-lity after initial recovery, non-disuse increased muscle weakness, and other complaints such as increased general fatigue and pain. Loss of motor units is compensated by collateral re-innervation and hypertrophy of muscle fibre. An elevenfold times increase in the motor unit region can be seen, and around double the muscle fibre area, corresponding to a fivefold increase in the number of muscle fibres in the motor unit. When loss of motor neurons can no longer be compensated for, muscle strength will decrease. Respiratory problems are present in a minority, but these need special attention and intervention. Evaluation and support through a special polio clinic is of value. The trainability varies according to the type and degree of polio changes. There may be a need for technical aids, especially for mobility, but time must be allowed for patients to accept reduced physical activity and changes in life habits recommended.
