A Parkinson’s Disease Handwriting Rehabilitation Kit—A Forensic Exploratory Study

Legal documents signed by individuals with Parkinson’s disease are often disputed due to inconsistencies in their signatures when compared to those executed prior to the disease. This exploratory study aims to develop a handwriting rehabilitation kit designed to improve fine motor skills in the elderly diagnosed with Parkinson’s disease. This study involved ten subjects with a diagnosis of Parkinson’s disease, four of whom participated in the rehabilitation program and used the kit, while the remaining six were assigned to the control group. All participants underwent traditional rehabilitation and clinical evaluation before and after the twelve-week intervention, as well as satisfaction questionnaires following the intervention. The main changes observed in the intervention group indicated progress, including a reduction in tremor and bradykinesia. The potential clinical and handwriting benefits, as well as the positive feedback and program adherence from participants, support the development of a user-friendly kit for this subset of the elderly population.
