Background: Diabetes mellitus (DM) has become a major chronic health problem worldwide resulting from defect in insulin action, secretion or both. It leads to macro vascular complication over long period such as cardiovascular disease, stroke and peripheral arterial disease. Purpose of the study: to determine the effect of selected range of motion exercise (Buerger- Allen Exercise) on peripheral circulation among patients with type II diabetes mellitus. Setting: Outpatient Medical Clinic at Shebin El Kom Teaching Hospital. Subjects: A consecutive sample of 100 adult patients were selected and divided alternatively into two equal groups: 50 patients for each group (study - control). Instruments: Four instruments were used for data collection: Structured interview questionnaire, physiological instrument, ankle brachial index and observational checklist. Results: mean scores of ABPI in the right side improved from 0.74±0.06 pre exercise to 1.0± 0.13after four weeks of exercise implementation among study group versus 0.71±0.12 and 0.71±0.11 in the control one. While in the left side the mean scores of ABPI improved from 0.72±0.13 pre exercise to 1.0± 0.13 after four weeks of exercise implementation among study group compared to (0.70±0.10) in the control group. Recommendations: A health teaching about Buerger Allen exercise should be carried out for all type II diabetic patients to improve their peripheral circulation. Besides, a colored booklet should be available and distributed to all diabetic patients.
