Reliability And Predictive Validity Of The Bedside Upper Limb Functional Evaluation Tool Among Stroke Subjects– A Psychometric Study

Upon approval of the study plan , informed consent will be taken from the subject. A consent form for participation and taking a video recording of him/her while the scale is being administered will be taken. The BUFET scale will be administered on the subject on the first day of referral. The principal investigator (PI) will score the subject based on BUFET scale on the first day. The PI will score the subject again after a washout period of 7 days. Both scores will be used to establish intra-rater reliability. Four other raters ( 4 postgraduate students trained to administer the scale) will be used. The raters will be briefed about the BUFET scale following which they will score the subject based on the video recording of subject performing the activities. The scores of the 4 raters & the PI will be used to establish the inter-rater reliability. Wolf Motor Function Test (WMFT) scale will be administered along with BUFET on the first day of referral. Both the scales will again be administered on the subject after 1 month of duration. To establish the predictive validity, the initial score as well as the change in score of the BUFET scale will be compared with the initial score and change in score of the WMFT scale.
