Official Title: A Study Investigating the Inter- and Intra- Rater Reliability of a Battery of Functional Standardised Outcome Measures in Neurofibromatosis 1

Brief Summary: Neurofibromatosis 1 (NF1) is a common inherited condition that affects 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. 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.

Detailed Summary:

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.

The 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

Current Primary Outcome:

  • 10 metre walk test [ Time Frame: Between 5 and 30 seconds per test on average. ]
    Participant is asked to stand at a point 2.5m before the start of a 10 metre walk way. They are advised to walk at their 'normal speed' from here to (a point 2.5m beyond the 10m walk way). The assessor times from the moment the participant's leading foot crosses the start point for the 10 metre walk way until the toes of the participant's leading foot crosses the end of the 10m walk way. Measurements are recorded in seconds and milliseconds. Participants can use their normal aids and orthotics if needed.
  • Functional Reach test [ Time Frame: 30 seconds per test ]
    Participant stands with arms straight out in front of him/herself at shoulder level and hands forming fists. The assessor sticks a ruler to the wall at the end of their hands. Participant is advised to lean forwards as far as they can without falling over and the assessor measures the distance they can reach against the metre ruler in centimetres and millimetres.
  • 9 hole peg test [ Time Frame: Up to 60 seconds per hand. ]
    Participant is sitting comfortably in a chair in front of a desk. The 9 hole peg test equipment is set up so that the bowl containing pegs is directly behind the pegboard and in front of the participant. Participants can rest the forearms on the desk but must use only 1 hand for each test. If not the test is invalid. The assessor measures from the time the fingers pick up the first peg from the bowl until the fingers place the last peg in the hole of the pegboard. Time will be recorded in seconds and milliseconds.
