Background: People with Parkinson’s disease (PwP) often report problems with their handwriting before they receive a formal diagnosis. Many PwP suffer from deteriorating handwriting throughout their illness, which has detrimental effects on many aspects of their quality of life. Aims: To assess a 6-week online training programme aimed at improving handwriting of PwP. Methods: Handwriting samples from a community-based cohort of PwP (n=48) were analysed using Systematic Detection of Writing Problems (SOS-PD) by two independent raters, before and after a 6-week remotely-monitored Physiotherapy-led training programme. Inter-rater variability on multiple measures of handwriting quality was analysed. The handwriting data was analysed using pre/post design in the same individuals. Multiple aspects of the handwriting samples were assessed, including writing fluency, transitions between letters, regularity in letter size, word spacing, and straightness of lines. Results: Analysis of inter-rater reliability showed high agreement for total handwriting scores, letter size, as well as speed and legibility scores, whereas there were mixed levels of inter-rater reliability for other handwriting measures. Overall handwriting quality (p=0.001) and legibility (p=0.009) significantly improved, while letter size (p=0.012), fluency (p=0.001), regularity of letter size (p=0.009) and straightness of lines (p=0.036) were also enhanced. Conclusions: The results of this study show that this 6-week intensive remotely-monitored Physiotherapy-led handwriting programme, improved handwriting in PwP. This is the first of its kind study using this tool remotely and it demonstrated that the SOS-PD is reliable for measuring handwriting in PwP.
