Background: In Israel in 1956 Gottheiner introduced outpatient rehabilitation programs in patients who had survived a myocardial infarction. In Germany one decade later these WHO phase III activities were established as well. At present any patient with cardiovascular disease is included unless suffering from acute illnesses or presenting with symptoms at rest. Gymnastics, stretching and the "historic" volleyball are completed by jogging, soccer, basketball and anaerobic exercise. Thus, a notable trauma rate would be expected especially in the elderly and those who are on anticoagulation.
Methods: A retrospective analysis evaluated questionnaires of 903 patients in 116 outpatient coronary care groups covering approximately equal to 270,000 patient exercise hours.
Results: 101 of 123 injuries (approximately equal to 1/2 200 patient exercise hours) occurred during games the majority of which having been distortions (53.7%), hematomas, or bruises (15.4%). Severe traumas included bone fractures (11.4%) and ruptured muscles, tendons, or ligaments (12.2%). One patient lost the sight of one eye due to a broken spectacle frame. Patients who had felt exercise as too exhausting (p < 0.001) or complained of cardiovascular symptoms (p < 0.01) showed a significantly elevated trauma rate.
Conclusions: Thus, in outpatient cardiac rehabilitation the trauma rate is within the range of healthy sports men. To prevent injuries sports should be limited to the patient's level of activity. Improved skills in techniques and strategies as well as unbreakable glasses are recommended.
