P0804 - Dual task during walking in patients with Multiple Sclerosis: cognitive or motor interference?
(ID 1453)
Abstract
Background
Impairment in dual task (DT) activities has been previously reported in patients with multiple sclerosis (MS). Most studies analyze DT during walking whether incorporating a second cognitive or motor task. More research is needed in order to define what type of task (cognitive or motor) determines the severity of the interference produced in the DT.
Objectives
1) To compare DT performance between patients with MS and healthy controls. 2) To analyze DT performance according to the type of task that interferes (cognitive or motor).
Methods
94 patients with relapsing remitting MS and 25 healthy controls (HC) were included. Patient age: 38.61 ± 11.44; Education: 13.26 ± 3.77; Disability (EDSS): 2.13 ± 1.16; Evolution: 9.66 ± 8.96. HC age: 34.00 ± 14.25; Education: 14.50 ± 2.65. Measuring instruments: Clinical variables: EDSS; Fatigue severity scale; Beck Depression Inventory II. Cognitive variables: BICAMS battery; DT: cognitive-motor task (walking while performing cognitive task) and motor-motor task (walking while performing motor task). The difference between performance in the single task and in the dual task situation was obtained. Parametric and non-parametric statistics were used, to define significance a value of p <0.05 was accepted
Results
: patients and HC did not differ in age (p = 0.12) and education (p = 0.11). Patient presented poorer performance than HC in cognitive-motor DT (U: between 334.50 and 238.50; p <0.05) but not in motor-motor DT (p> 0.05). Patients with EDSS> 2, presented lower performance than the controls in both types of task (p <0.05). The motor-motor task differentiated patients with EDSS <y> 2 (t: 2.85 and 3.51; p <0.05).
Conclusions
MS patients show impairment in the DT performance when the second task is cognitive. In patients with greater disability, alteration is found in both DT. Studying patient’s performance in DT allows a more ecological approach to their symptoms in order to directly intervene in daily life alterations.
P1012 - Coping Strategies: Seeking personalized care in Multiple Sclerosis. A patient reported measure– Coping Responses Inventory. (ID 1548)
Abstract
Background
Background: Coping is defined as a set of cognitive and behavioral efforts made to master stressful specific demands. Adaptation to chronic diseases, such as Multiple Sclerosis (MS), depends on the effectiveness of coping.
Objectives
Objective: to assess the psychometric properties of the Coping Responses Inventory (CRI-A) in the subpopulation of MS patients, to verify the transferability of the instrument, which has already been validated in the Argentine general population and to assess the analysis of external criterion validity, by studying the relationship between coping styles and physical disability, depression, fatigue and years of evolution of the disease and clinical course.
Methods
Methods: 90 MS patients were included; Outcomes measures: CRI-A Inventory, Expanded Disability Status Scale (EDSS), Beck Depression Inventory and Fatigue Severity Scale.
Results
Results: 95.56% of the patients had Relapsing-Remitting MS (RRMS), 2.22% Primary-Progressive MS (PPMS), and 2.22% Secondary-Progressive MS (SPMS). The group comprised 59 women (65.56%), with a mean age of 40.97±12.85 years and mean education of 13.46±3.93 years. The group shows a mean of 13.92±10.45 for depression, 3.77±1.72 for fatigue, 10.76±9.72 for disease evolution and 2.48±1.79 for disability. CRI-A Inventory maintains the psychometric properties of the Argentine general population in the MS subpopulation, with adequate validity and reliability. The respondents most frequently utilized a problem focused coping style. A significant positive correlation was found between the problem-focused coping style and education (r= 0.31). As regards clinical variables, significant positive correlations were found between the emotion‑focused coping style and fatigue (r=0.21) and depression (r= 0.43). Nevertheless, when studying each of the 8 coping strategies on their own, a significant positive correlation was found between 3 strategies of the emotion-focused coping style: avoidance (r=0.27), acceptance (r=0.27) and emotional discharge (r=0.42), and depression. In addition, the seeking alternative rewards strategy was linked to the disease evolution and fatigue (r= 0.24/-0.22).
Conclusions
Conclusions: The results demonstrate the transferability of the CRI-A of the general population of Argentina in the subpopulation of patients with MS. Patients with MS develop more problem-focused strategies.
