The complications of NF1 are widespread and can lead to varied difficulties dependent on the location of neurofibromas and their secondary complications. At present evaluation of the effect of treatments in NF1 is based on a clinician's neurological assessment, magnetic resonance imaging and positron emission tomography but it is apparent that imaging results do not always link with clinical and functional changes in an individual. This study aims to evaluate the reliability (stability) of a range of functional standardised outcome measures in adults with NF1.", 'detailedDescription': "Neurofibromatosis 1 (NF1) is an inherited condition that occurs in 1 in 2,500 births; affecting the skin, bone and nervous system. The complications of NF1 are widespread and can lead to varied difficulties dependent on the location of neurofibromas and their secondary complications. One person with NF1 may have minimal issues whereas another may be profoundly disabled; one may have difficulties using their hands and arms and another may have difficulties standing from a chair. New pharmacological and nonpharmacological treatments for NF1 are currently being developed and they have potential to dramatically influence a person with NF1's life. At present evaluation of treatment effect in NF1 is based on a clinician's neurological assessment, magnetic resonance imaging and positron emission tomography and it is apparent that imaging results do not always link with clinical and functional changes in an individual. Therefore clinicians and researchers agree that the analysis of treatment effect needs to include the evaluation of a person's function. The findings from this study will improve the care of people with NF1 by ensuring that we are able to measure functional changes in a person with NF1 with greater confidence, meaning that we can start, continue or cease treatments based on the holistic picture of an individual.\n\nThe world confederation of physiotherapists (WCPT) stipulates that standardised outcome measures (SOM) are used to provide a quantitative measure of capability, and to evaluate the impact of treatment on function. There are a wide range of SOM's that evaluate function (e.g. walking, standing from a chair, use of hands) so a SOM is chosen by the clinician based on the patient's presenting functional difficulty and the scientific credibility of the SOM. Scientific credibility (robustness) is based on scientific properties of the SOM i.e. how stable the SOM is (reliability) and whether it assesses what it is intending to assess (validity). It is important to evaluate each SOM within the target population as variability within that condition, strongly influences the SOM's reliability and validity (de Vel 2011).\n\nAt present, functional SOM's have limited scientific and subsequent clinical credibility when used in people with NF1 because their scientific properties have not yet been evaluated within this patient group which means that if they are used clinically or within research, there is an inherent element of doubt when interpreting the SOM's results. The objective of this research team is to create a core set of functional SOM's which have undergone rigorous scientific evaluation so that they can be used in the future for clinical practice and for research purposes in adults with NF1.\n\nThis study aims to evaluate four commonly used SOM's for reliability in adults with NF1 (over 16 years of age). The measures chosen for evaluation are the 10 metre walk test, the timed up and go test, the functional reach test and the nine hole peg test. Interrater reliability (the test result remains the same when reviewed by different people) and intrarater reliability (the test result remains stable when reviewed twice by the same tester) will be evaluated. From this data, we will be able to calculate the standard error of measurement an additional important scientific characteristics of SOM evaluation."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'minimumAge': '16 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'All adults (over the age of 16 years) with a clinical diagnosis of neurofibromatosis 1 who attend the neurofibromatosis clinic for appointments at Guys hospital, London and who fit the inclusion/exclusion criteria for the trial are eligable to participate in the study.', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* All patients aged 16 years or older who fulfil the diagnostic criteria for NF1 who do not have a significant mobility or balance impairment that is unrelated to their NF1,\n* Able to walk more than 10 metres without physical assistance (may use walking aids)\n* Patients who attend the national NF1 service at GSTT\n\nExclusion Criteria:\n\n* Patients who are unable to provide informed consent will be unable to participate in this study.'}, 'identificationModule': {'nctId': 'NCT02479360', 'briefTitle': 'Reliability of Functional Outcome Measures in Neurofibromatosis 1', 'organization': {'class': 'OTHER', 'fullName': "Guy's and St Thomas' NHS Foundation Trust"}, 'officialTitle': 'A Study Investigating the Inter- and Intra- Rater Reliability of a Battery of Functional Standardised Outcome Measures in Neurofibromatosis 1', 'orgStudyIdInfo': {'id': 'RJ115/N174'}}, 'armsInterventionsModule': {'armGroups': [{'label': 'Outcome measurement', 'description': "Each participant will be asked to complete each standardised outcome measure (SOM) three times and each trial will be videotaped by the researcher.
