A comparative study between calcium and vitamin d versus calcium and sun light exposure on bone mineral density in hemiplegic patients after stroke

الملخص EN

Background and purpose : Little information is known about the changes in The researcher compared treatment with calcium and vitamin D versus calcium and sun exposure in the improvement of bone mineral density after stroke. Methods : The patients completed questionnaire about their age, sex, history of stroke, presence of diseases other than stroke.

The questionnaire was performed face to face in the presence of witnesses.

Bone mineral density was measured using DEXA for 27 patients.

The patients then were divided into two groups, one group received calcium and vitamin D and the other group received calcium and were exposed to sun light one hour daily from 8 to 9 in the morning.

After six months bone mineral density was measured again and the data was analyzed using SPSS version 12. Results : The T-score for bone mineral density reveals that bone mineral density in the hemiplegic side was lower than the non-hemiplegic side.

In both strategies of treatment bone mineral density was improved in most cases with different degree, but the results in case of calcium and sun light exposure were better Conclusion : Bone mineral density was reduced significantly on the hemiplegic side in stroke patients, this predisposes patients to fracture.

The decrease in bone mineral density may be due to decreased sun exposure and malnutrition associated with stroke in addition to disuse of the affected part or due to mixed factors.

The factors sex, age, the affected part are of significant effect on both the progression of disease and the result of treatment The administration of calcium and vitamin D or calcium and sun light exposure improved bone mineral density.

The results show that calcium plus light sun exposure provide better results 71 % versus 66 % of that calcium plus vitamin D.

The researchers recommend continuity of treatment for another six months and to follow up patient again.

Also it is recommended to make benefit of sun light exposure in treatment of reduced bone mineral density after stroke since it provides good results and is cost effective.
