ITK researchers validated the international Amyotrophic Lateral Sclerosis Functional Rating Scale

ALSFRS-R is a scale for evaluating the functional status of patients with amyotrophic lateral sclerosis. Recurrent use of this scale allows also for monitoring disease progression, e.g. during treatment. It constitutes the basic tool used by neurologists working with ALS patients around the world.

A team of ITK researchers led by Dr. Stanisław Maksymowicz, asistant professor at the Department of Psychology and Sociology of Health and Public Health, Collegium Medicum of the University of Warmia and Mazury in Olsztyn, translated and validated this tool in Polish patients for the first time in history.

The validation process was very complex. A neurologist, medical sociologist and neuro-speech therapist were involved. The entire instrument was positively validated under the specific Polish conditions and it may be successfully used as a scientifically-proven tool in clinical practice – points out Dr. Maksymowicz.

A paper in English, along with the tool itself, provided in a format that is ready-to-use in clinical practice in Poland, have been published in the international peer-reviewed scientific journal “Neurological Science” and are available at:
