A randomised clinical trial was conducted in the Department of Physical Medicine, Chittagong Medical College Hospital from July, 2001 to June, 2002. The objectives of the study were to find out the effects of cervical traction (CT) and exercise on the patients with chronic cervical spondylosis. A total of 199 patients with cervical spondylosis were included in the clinical trial. One hundred patients were treated with cervical traction plus exercise and 99 patients were treated with non-steroidal anti-inflammatory drug (NSAID). Posture correction advice was given to all patients. The patients were treated for 6 weeks. There was a marked improvement in both the groups after treatment (P<0.001). But there was nearly significant difference regarding improvement in treatment with CT plus exercise than with NSAID (P = 0.06). The results indicate that the improvement of the patients with chronic cervical spondylosis was more in CT plus exercise than analgesics. So, CT & neck muscle strengthening exercise may have some more beneficial effects than NSAIDs on chronic cervical spondylosis.
Physical exercise does not only have positive effects on physical fitness but also on mental health. However, there has been little empirical study on effects of rehabilitation programmes based on physical exercise in cancer patients. We conducted a study to examine the interrelation between the participation of breast cancer patients in an exercise rehabilitation training and aspects of quality of life and physical fitness. 28 patients with not metastasized mamma carcinoma participated in a structured exercise rehabilitation program twice a week for ten weeks. Before and after the intervention the patients were asked to fill in questionnaires to assess their quality of life. At the same instants they underwent physical examination and a bicycle ergometry as well as a blood drawing. The training was aimed at changes at the social, emotional, as well as the motor physical level. Pre-post comparisons demonstrated an improvement in quality of life, such as decreased levels of depression and anxiety. Furthermore the women proved to show an obvious increase in physical fitness. Present results support an implementation of an exercise rehabilitation training for breast cancer outpatients.

Respiratory and cardiocirculatory response to rehabilitation calisthenics in 30 patients, aged 39-66 years, with recent myocardial infarction was studied. Respiratory exchange (Douglas-Haldane method), heart rate, blood pressure, oxygen pulse and electrocardiogram during exercise were investigated. Rehabilitation was performed between the 4th and 21st day of myocardial infarction, in 4 periods with gradually increasing effort, according to the model A designed at the Cardiology Institute in Warsaw. The time of exercises was 10-18 min, depending on the period of rehabilitation. It was found that lung ventilation, tidal volume, oxygen uptake and carbon dioxide output were increased by 20-40% during exercise of the I and II periods of rehabilitation and by 60-100% in the III and IV periods of mobilization. Energy cost of calisthenics rehabilitation was in the lightest case 13 kJ/min. The most increase in respiratory exchange caused exercises performed in sitting position, walking and stair climbing. The last type produced also the highest rise in heart rate (mean 20%) and systolic blood pressure (mean 17% of resting values).
