Reliability of Functional Outcome Measures in Neurofibromatosis 2

   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. The selected SOM's are the modified nine-hole peg test, the four square step test and the modified clinical test of sensory integration and balance. A doctor will watch the video on 2 separate occasions to evaluate intra-rater reliability. Inter-rater reliability will be assessed through asking three other neurofibromatosis specialist professionals (two NF2 consultants and one NF2 specialist nurse) to review the video and to score each measure completed. Once the filmed sessions have been analysed by the relevant clinician's the data will be destroyed in line with Trust policy. Each participant will also be required to complete the INFI-QOL questionnaire, the dynamic visual acuity test and provide information about the number of falls/near misses they have had over the past 12 months

   description

   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.
