Items are scored on a 4-point scale (0 = no response, 1 = partial level of response, 3 = nearly full level of response, 4= complete level of response). The assessment has good internal consistency (\> 0.70) and strong intra-rater reliability (ICC=0.96). CHOP-INTEND will be used for participants who are not independent sitters regardless of age.

Canadian Occupational Performance Measure (COPM)

时间窗: Week 0, Week 12, Week 24

The COPM measures an individual's self-perception of occupational performance on self-care, productivity and leisure. The COPM is used by OTs in initial assessments to set goals and plan treatment focusing on activities that an individual needs, wants or is expected to do. The importance of activities are rated on a 10-point scale (1 = not important at all to 10 = extremely important). The individual selects the five most important activities, which are rated on a 10-point performance scale (1 = not at all able to 10 = able to perform extremely well) and for satisfaction (1 = not at all satisfied to 10 = extremely satisfied). COPM will be completed for all participants.

Goal Attainment Scaling (GAS)

时间窗: Week 0, Week 12, Week 24

Goal Attainment Scaling (GAS) is used to evaluate an individual's progress towards client/family goals. Each scale is developed based on assessment and collaboration between the therapist and the client/family. A 5-point scale, ranging from - 2 to +2, is used. A numeric value is assigned to each level of performance. On the original scale, 0 is used to represent the expected level of outcome, with +1 and +2 indicating greater than expected progress and -1 and -2 indicating less than expected progress (reference). Various protocols have been developed to improve the reliability and validity of GAS goals and they can be subjective in nature. GAS will be completed for all participants.

Home Exercise Diary

时间窗: Weeks 1-24

This purposefully developed form will be completed by the participant's parent/guardian each time the home exercise program is completed. The parent/guardian will be asked to fill out the week of the intervention, day of the week (e.g., Monday), which of the OT/PT exercises were completed (i.e., Yes, No, N/A), and any comments (i.e., about the participant's mood, adverse events, and duration of the exercises). Additionally, the parent/guardian will indicate if any additional activities were completed by the participant in the past week.
