Abstract
Introduction: Multiple sclerosis (MS) is one of the most common chronic, progressive and disabling neurological disorders. Its diagnosis is based on the detection of multiple inflammatory demyelinating white matter lesions. Multiple sclerosis is one of the most common neurological disorders, which influence the ability of subjects to stand and walk. The objectives were evaluation of energy consumption in MS patients with three different clinical forms and compared with healthy subjects.
Methodology: 45 women with MS (separated to three groups based on dominant symptoms, ataxia (n=16), spastic (n=15) and ataxic-spastic (n=14)) and 13 healthy women participated in the research. A heart rate Polar Electro Finland was used to record the heart rate during resting and walking. The energy consumption was measured based on physiological cost index (PCI). ANOVA, Post-hoc Tukey analysis were used for statistical analysis (P<0.05).
Results: There was a significant difference between the walking speed of the healthy group and the three groups of patients (P<0.001), but there was no significant difference between the three groups of patients in the variable (P>0.05). There was no significant difference between the resting and walking heart rate of four groups. There was significant difference between PCI of healthy subjects with ataxic-spastic group (P<0.01).
Discussion: The performance of the cardiovascular system in MS subjects was the same as healthy subjects. Their energy consumption increased significantly due to a decrease in walking speed. It seems that the weakness of muscles of lower extremity and spasticity of knee extensors play a significant role in this regard.
