    Reliability and validity of the Swedish Fatigue Assessment Scale when self-administrered by persons with mild to moderate stroke2016In: Topics in Stroke Rehabilitation, ISSN 1074-9357, E-ISSN 1945-5119, Vol. 23, no 2, p. 90-97Article in journal (Refereed)
    Abstract [en]

    Objective: To examine internal consistency, test-retest reliability, floor/ceiling effects and construct validity of the Fatigue Assessment Scale (FAS), when self-administrated by persons with mild to moderate stroke.

    Method: The FAS was translated into Swedish and tested for psychometric properties when self-administrated by persons with mild to moderate stroke. Participants, consequently selected from the stroke unit admission register received a letter with three questionnaires: the FAS, Short Form Health Survey (SF-36) subscale for vitality and Geriatric Depression Scale, GDS-15. Within two weeks, a second letter with FAS was sent for re-test.

    Result: Seventy-tree persons with mild to moderate stroke participated in the study. Internal consistency was good (Cronbach’s alpha 0.82). The test and retest reliability of individual items showed that five items out of 10 items were good (weighted kappa > 0.60), four were moderate (0.40-0.60), and one was fair (0.22). The relative reliability between total scores was good (ICC 3.1 = 0.73) and the absolute reliability was nine points, meaning that a change of at least nine points in total score implies a real change of fatigue level. Correlation analysis showed that the Swedish FAS correlated with the SF-36 subscale for vitality (rs = - 0.73) and GDS-15 (rs = 0.62), suggesting convergent construct validity. There were no floor or ceiling effects.

    Conclusion: The Swedish translation of the FAS used as a self-administrated questionnaire is reliable and valid for measuring fatigue in persons with mild to moderate stroke.

    RehAtt – scanning training for neglect enhanced by multi-sensory stimulation in Virtual Reality2016In: Topics in Stroke Rehabilitation, ISSN 1074-9357, E-ISSN 1945-5119, Vol. 23, no 3, p. 191-199Article in journal (Refereed)
    Abstract [en]

    Background: There is a lack of effective treatment for neglect. We have developed a new training method, RehAtt (TM). The objective of this study was to determine whether RehAtt (TM) improves spatial attention in chronic neglect after stroke. Methods: RehAtt (TM) consists of a computer with monitor, 3D glasses, and a force feedback interface (Robotic pen) giving sensory motor activation to the contra-lesional arm. The software combines visual scanning training with multi-sensory stimulation in 3D virtual reality (VR) game environment. Fifteen stroke patients with chronic neglect (duration > 6 month) had repeated baseline evaluations to confirm stability of symptoms. There were no test-retest effects for any of the tests. Thereafter, all patients trained 15 h in RehAtt (TM) (3 x 1 h for 5 weeks). A neglect test battery and Catherine Bergego Scale, CBS, were used to assess behavioral outcome after intervention. CBS was also used at a 6-month follow-up. Results: Using repeated measurement analysis improvements due to the training were found for Star cancellation test (p = 0.006), Baking tray task (p < 0.001), and Extinction test (p = 0.05). In the Posner task improvements were seen fewer missed targets (p = 0.024). CBS showed improvements in activities of daily life immediately after training (p < 0.01). After 6 months the patients still reported improvement in CBS. Conclusion: RehAtt (TM) is a new concept for rehabilitation of neglect. Training with the VR-method improved spatial attention and showed transfer to improved spatial attention in activities of daily living in chronic neglect. Our results are promising and merit further studies.
