A study covering 4057 patients of acute poliomyelitis over a period of seven years is presented. They were evaluated for recovery pattern in paralysed muscles and predicting the prognosis. The study revealed that by the time of third muscle testing i.e. 4 months from onset, most of the recovering muscles regained approximately 60 percent of the total strength that they will ever achieve. The rate of recovery was highest (54.96%) in the second months (i.e. between first and second muscle charts) and progressively lessened. There was no significant recovery after six months. It was further observed that paralytic poliomyelitis most commonly affects the children in the age group of six months to one year. Tibialis anterior (11.3%), quadriceps femoris (11.08%) and tibialis posterior (11.08%) showed the maximum incidence of paralysis in lower limbs. In the upper limb muscles, the initial rate of recovery at the end of 4 weeks was less than that seen in the lower limbs. The most commonly paralysed muscle in upper limb was deltoid and in the hand it was opponens pollicis.
