Affecting factors and degree of recovery were analysed among 101 brachilal plexus injury patients who were followed up for at least 6 months after being referred to this department's Electrodiagnostic Laboratory from January 1, 1980 to December 31, 1986. The patients were classified as preganglionic lesion, postganglionic lesion and combined pre and postganglionic lesion after paracervical muscle electromyography and sensory nerve conduction study. The results showed satisfactory functional recovery in 18.2% of preganglionic lesion patients, 64.9% of postganglionic lesion patients and 6.2% combined lesion patients. According to the types of brachial plexus injury, satisfactory functional recovery was found in 80.5% of Erb's type and in 38.0% of Klumpke type. According to the causes of the injury, satisfactory functional recovery was found in 60.9% of birth palsy patients and in 46.1% of other causes.
