Outcome Measures for Individuals With Multiple Sclerosis: Recommendations From the American Physical Therapy Association Neurology Section Task Force

Abstract

Various studies have described the benefits of using outcome measures (OMs) in physical therapist practice1–3; however, multiple barriers interfere with their use (eTab. 1).1,3,4 Most notably, a limited understanding of how to select and apply the best OM has been reported to be a barrier.3,4 Wedge et al3 reported that physical therapists do not always critically evaluate the psychometric properties of OMs, are unfamiliar with OM-related resources, and have difficulties determining patient suitability for particular OMs. Physical therapists working with people with multiple sclerosis (MS) have additional challenges when selecting OMs. Multiple sclerosis is a complex, heterogeneous, and progressive disorder causing a wide variety of symptoms among patients.5,6 Symptom variability in individual patients throughout the course of the disease also must be considered. Additionally, people with MS are treated in a variety of settings, which may affect OM selection and use (eg, due to limited space and equipment in a home environment). Thus, selecting 1 or 2 OMs for use with all people with MS is challenging, requiring the clinician to determine the most appropriate OMs to measure relevant constructs. Although some resources exist to assist the physical therapist with identifying and selecting OMs for people with MS,7–13 literature is lacking that describes a consensus-based method to determine which OMs are appropriate for people with MS at various disability levels and in different practice settings. In 2009, the American Physical Therapy Association (APTA) Neurology Section (“the Section”) began a process to develop recommendations for the use of OMs for patients with neurological conditions, beginning with stroke (information pertaining to the Section's OM recommendations is available elsewhere14). The following year, the Section expanded its efforts by creating a task force …
