Summary
468 muscles in different grades of post-poliomyelitis paralysis were studied for six months after the onset of disease. Patients reporting earlier showed better recovery. The maximum number of muscles reaching normal grade were from muscle power 3 and above.
Recovery at different time intervals, has been more or less uniform throughout the period of study. The maximum quantum of recovery was observed in the tibialis anterior and quadriceps groups of muscles, although, numerically, aminimum number of tibialis anterior muscles recovered. The maximum number of muscles improved among the hip extensors and the tensor fascia lata. The recovery of completely paralysed muscles was observed to be 25.2%. Prognosis was very poor where the whole limb was completely flail or both the associated muscles of the primary muscle were completely paralysed.
The quantum of recovery of any particular muscle could be predicted from the grade of muscle power on admission provided the patients reported for treatment within three months of the onset of disease.
