98. It has good construct validity, with a good correlation with other self-rated assessment tools, including the HAL. The FISH had a good correlation with the clinical score (r = –0.61) and the radiological score (r = –0.38) [17]. The FISH was originally designed to compare a patient’s basic functional ability with that of normal healthy individuals, and was not designed to assess challenging activities in individuals. Therefore, like the PedHAL, it may have a ceiling effect when applied to those with minimal

musculoskeletal changes [19]. It has, however, been used effectively in studies from varied cultural backgrounds [20–23]. While the assessment of Activities involves the ability to execute tasks or actions, Participation is defined as involvement in a life situation, such as sport, leisure, Palbociclib cost work or social events [4]. The ICF provides a single list of activities and participation in nine domains. According

to their needs and purposes, investigators designate some domains as activities and others as participation [4]. Although there are several generic instruments used to assess BGB324 concentration participation, only a few have been used in haemophilia [2]. While the items in FISH are primarily in the domain of ‘activities’, the HAL has several questions that involve the subject’s interaction with others and with the environment. Assessing ‘participation’ across cultures is challenging, as several items/questions may not be equally relevant. In a study from India several items related to participation in the HAL had poor cross-cultural validation [17]. The Canadian Occupational Performance Measure (COPM) is an open-ended questionnaire that allows patients to prioritize

their main concerns – both in the domains of functional activities and in participation. It has been shown to be useful in making individualized management plans for patients with haemophilia [24]. Its ability to assess different intervention programmes is, however, limited. The feasibility of developing a tool to assess participation, which is contextually relevant and universally applicable, needs to be explored. It has been a long felt need to develop a core set of disease-specific tools to assess the different domains of musculoskeletal outcome as defined by the ICF. The WFH has taken the first step by identifying a core set of tools, MCE and making them available on the World Wide Web (http://www.wfh.org/2/7/7_0_Compendium_Assessment_Tools.htm). These tools need to be used more widely in centres not involved in their development, to judge their acceptability across different countries. Long-term studies are necessary to determine their efficacy in assessing the severity of joint arthropathy. Radiological assessment has been one of the oldest clinimetric tools used to measure progression of joint arthropathy. With newer imaging modalities, it has been possible to detect changes in joints before they are clinically apparent.
