No clue how knowing this helps your stroke recovery. That is really the only valid question that stroke researchers should be answering for everything they do. A
Abstract
Background
In
highly invasive diseases, metabolism commonly changes. Hypercatabolism
is frequent in acute stroke, and nitrogen balance tends to be negative.
However, there has been no study describing nitrogen balance in subacute
and chronic stroke patients. The present study aimed to examine
nitrogen balance in the subacute and chronic phases and to identify the
factors related to it.
Methods
Nitrogen
balance was calculated from the collected urine of 56 patients with
subacute stroke [mean (SD) 53.8 (18.4) days post-stroke] who were
admitted for rehabilitation for their first-ever ischaemic or
nonsurgical haemorrhagic stroke. In the first experiment, their nitrogen
balance was measured during the rehabilitation phase, and factors
(type, severity of hemiparesis, activities of daily living, dysphagia
and malnutrition status) related to it were evaluated. The second
experiment was performed to describe the time course of nitrogen balance
in 31 consecutive patients, with assessments made at admission and at
discharge.
Results
Nitrogen
balance was positive in all patients in the subacute phase. A
significant difference was seen in nitrogen balance between high and low
fat-free mass in male patients. In the chronic phase, nitrogen balance
was positive in 96% of the patients. There was no significant difference
in nitrogen balance between discharge and admission.
Conclusions
In
the subacute and chronic phases of stroke, it was confirmed that
hypercatabolism had resolved and that intensive rehabilitation is
possible in the convalescent period of stroke.
