Purpose[edit | edit source]
The Multiple Sclerosis Functional Composite (MSFC) designed by "National MS Society's Clinical Outcome Assessment Task" and is a standardized tool used to quantify degree of disability in patients with multiple sclerosis (MS)[1]. Limitations in EDSS leads to development of MSFC in the early 1990's, to improve clinical assessment of patients with multiple sclerosis[2][3]. The traditional scales such as EDSS scale are inadequate in measuring some key aspects of MS for example cognitive function and have psychometric limitations as well[1].
Technique[edit | edit source]
MSFC covers three functional domains[3]:
- Ambulatory Function
- Hand Function
- Cognitive function
Performed with in 20 minutes.
Hand function is tested with the nine-hole peg test[3].
PASAT was originally included to cover the cognitive dain. It measures processing speed and working memory, both of which are frequently affected functions in MS patients[3].
Ambulatory function is tested with the timed 25-foot walk test (T25W). The T25W is a reliable test for patients with more severe gait impairment, because it primarily assesses walking speed[3].
The results of the tests that assess these domains are depicted in an interval scale (seconds or number of correct responses) and can be converted to a Z score that is based on values of a reference population. An overall score can be calculated by averaging the Z score of the subtests[3].
Evidence[edit | edit source]
has good intra- and inter-rater reliability and it results in a score on a continuous scale. The MSFC has been used as the primary outcome in a treatment trial in SPMS [49]. While MSFC progression was slowed, treatment effects were not observed with the EDSS. If the components are applied in a sensible way, the MSFC may be used as the primary endpoint in future clinical trials.
