Bone mineral density in patients with stroke
Abstract
OBJECTIVE: Stroke is an acute neurologic dysfunction of vascular origin, characterized by loss of voluntary movement, sensory disturbances, and neurologic findings in the contralateral half of the body. Acute and long-term complications because of immobilization are seen in all organ systems. The aim of this study was to determine any differences between the affected and unaffected sides' bone mineral densities of acute and chronic stroke patients.
DESIGN: In this study, we determined the bone mineral densities (BMD) of 30 male patients with acute (0-20 days) and 30 male patients with chronic (6 months or longer) stroke and compared the densities with the normal side. Upper and lower limb BMDs were measured by dual-energy x-ray absorptiometry. Additionally, patients were evaluated for the degree of spasticity, the phases of motor improvement, and the activities of daily living.
RESULTS: In acute-phase stroke patients, BMD of the affected side was not significantly different from BMD of the normal side. BMD of both upper limbs of acute stroke patients was not different from normal side upper limb BMD of chronic stroke patients. In both acute and chronic stroke patients, affected and unaffected side lower limb BMDs (femur total BMD scores) were not significantly different. However, in chronic stroke patients, affected side BMD of Ward's region was significantly higher compared with the normal side. There is no correlation between BMD and Brunnstrom phases, Ashworth scales, and…
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 30 participants or records.
