Background:
We keep acute cerebral infarction patients in bed for several days to maintain cerebral blood flow.
Objective:
We studied whether disuse atrophy occurs during the bed rest period in the patients with mild ischemic stroke.
Patients and Methods/Material and Methods:
We investigated 26 patients who were admitted to our hospital from Oct
2015 to March 2017. Their National Institutes of Health Stroke Scale
score was under 7, and they were under 80 years old and gave consent. We
treated them with 4 days in the supine position, and after that we
gradually raised the upper half of their beds to angle of 90 degrees. We
administrated rehabilitation during this period. We investigated them
with bioelectrical impedance analysis (BIA) over a 7 cm below and above
section from the center of the thigh, and obtained the muscle cross
sectional area index (MCAI), which reflects muscle volume. Measurements
were taken 2 to 3 times over a period of 5 days. Any data, which changed
more than or less than 20 % from the previous measurement data was
excluded. We analyzed the first and last day of the 5 days data period
using the paired t-test. This study was carried out in accordance with
the Human Research Guideline of the Internal Ethics Review Board of our
hospital.
Results:
The averaged MCAI impaired side did not change significantly from 0.821 to 0.804 (p=0.249).
Conclusion:
In the patients with mild cerebral stroke, the administration of
bed-side rehabilitation may prevent the occurrence of the disuse atrophy
during the bed rest period.
