Abstract: | ObjectivesTo determine the test-retest reliability and validity of the Lower Extremity Motor Activity Log (LE-MAL) for assessing LE use in the community in adults with multiple sclerosis (MS).DesignProspective analysis of measures conducted by trained examiners.SettingParticipants were evaluated by telephone on several measures of LE use.ParticipantsAdults with MS (N=43).InterventionsNot applicable.Main Outcome MeasuresThe LE-MAL has 3 subscales (Assistance, Functional Performance, and Confidence). It was administered twice, at least 2 weeks apart. The Multiple Sclerosis Walking Scale (MSWS-12), Patient Determined Disease Steps (PDDS), and Mobility Scale were only administered during the first call.ResultsThe test-retest reliability of the composite and the 3 subscale LE-MAL scores were high (intraclass correlation, >0.94). The composite and subscale LE-MAL scores were strongly correlated with the MSWS-12, PDDS, and Mobility Scale scores (r=–0.56 to –0.77; P<.001).ConclusionThis initial study suggests that the LE-MAL reliably and validly measures LE use in the community in adults with MS. |
