Abstract
BackgroundValid and multidisciplinary assessment of a stroke patient's ability to perform activities of daily living is very important to define individual goals and to plan targeted rehabilitation. Until today, there is no observation scale that relies on International Classification of Functioning, Disability and Health (ICF). The aim of the present study was to develop and evaluate the reliability and validity of a new multidisciplinary observation scale for stroke patients, shortly called LIMOS, which is based on ICF.MethodsIn a first phase, LIMOS was defined, using a Delphi approach, by an expert panel and a pilot testing was conducted in a small group of stroke patients (n =10) to investigate feasibility and practicability. In a second phase, LIMOS was assessed for its reliability (internal consistency and test-retest reliability) and validity in a large cohort of stroke patients (n = 102). For convergent validity, the correlation between total scores of the LIMOS and the Functional Independence Measure (FIM) was assessed.ResultsLIMOS consisted of seven ICF chapters incorporating 45 domains. A high internal consistency (=0.98) of LIMOS was found. Furthermore, good test-retest reliability at item and subscale level was found. Principal component analysis revealed that among the seven ICF chapters, four components could be found: (1) interpersonal activities, mobility and self-care, (2) communication, (3) knowledge and general tasks, and (4) domestic life. Significant associations were found between LIMOS and the FIM indicating good convergent validity.ConclusionsThe new LIMOS is a reliable and valid observation scale for stroke patients based on ICF, which can be used by a multidisciplinary team working in a neurorehabilitation setting.

Summary
An estimated 50 million stroke survivors worldwide currently cope with significant physical, cognitive and emotional deficits. To optimize functional outcome of a stroke patient, a valid detection of a patient’s ability to perform ADL is unequivocal at the start as well as at the end of rehabilitation procedures. This enables clinicians to set measurable treatment goals, to make appropriate discharge arrangements, or to anticipate the need for community support [3, 5]. Clinicians and researchers often use basic ADL measurements, such as the Barthel-Index, the extended Barthel Index, modified Ranking Scale (see for an overview Weimar et al 2002, [6]) or the Functional Independent Measurement (FIM) [5, 7, 8]. The aim of the present study was to develop and evaluate the reliability and validity of a new multidisciplinary observation scale for stroke patients, shortly called LIMOS, which is based on ICF
