This case involves a 42-year-old man who was undergoing occupational therapy for a severed a tendon he sustained from a severe German Shepherd bite. During the course of his therapy, the supervising occupational therapist allowed a student therapist to conduct a tendon exercise on the patient. Following the exercise, the patient ruptured his tendon and required additional surgeries and grafts. It was alleged that these exercises were too advanced to be conducted by a student. An expert in occupational therapy who specializes in hand treatment was sought to opine on whether the supervising occupational therapist was negligent in allowing the student to conduct these exercises.
