The primary purpose of the study was to address activity of daily living limitations for three reasons:
- Activity restriction was identified as important by people with PD and their carers;
- We are using change in activity of daily living restriction as our main outcome measure;
- We know from other populations (such as stroke) that this intervention is effective in improving quality of life and reducing carer burden.
However, it is recognised that each patient presented with very individual needs and goals, and that therapists have professional autonomy. We just asked that activity restriction be addressed first.
