Type A personality describes someone who is hard working to the point of being driven and unable to relax. The Type A person works hard and plays hard. They tend to be over achievers and have a strong sense of time urgency.

A study of patients with arm injuries was done in the Netherlands. This showed white-collar workers (office workers) return to work sooner than blue-collar workers (manual laborers). The authors of this study think this is because of the workers’ level of education. Type of personality wasn’t studied.

There are other factors that decide how soon a patient returns to work. These include the level of injury, the extent of the injury, and how strong is the patient’s grip. The higher the injury (for example, above the elbow), the worse the result. Patients with more than one nerve or tendon cut also had poorer results.

Overall, the most important factor in returning to work after an arm injury was following the hand therapist’s advice. Type A patients may be more likely to complete the prescribed exercise program, but this hasn’t been proven yet.
