A fisherman who could not row

摘要

In July, 2007, a 28-year-old man came to our institute. Until recently, he had worked as a fisherman, off the coast of Kerala-where boats traditionally carry 4-5 fishermen, who must row against strong currents and waves. He had had to leave his job, because, when rowing, he could not keep to the same rhythm as his fellows: he could not extend his elbows rapidly after flexion. After 5 min, this problem disappeared. Additionally, he could not release his grip quickly, after holding things tightly. His problems had gradually increased over 5 years; he had had to leave his job, and was now working as an assistant in a roadside shop. He had no other medical history of note.
