Prediagnostic expressions in health records predict mortality in Parkinson's disease: A proof-of-concept study

BACKGROUND: Parkinson's disease (PD) is a progressive neurodegenerative disease with no cure and few treatment options. Its incidence is increasing due to aging populations, longer disease duration and potentially as a COVID-19 sequela. Photobiomodulation (PBM) has been successfully used in animal models to reduce the signs of PD and to protect dopaminergic neurons. OBJECTIVE: To assess the effectiveness of PBM to mitigate clinical signs of PD in a prospective proof-of-concept study, using a combination of transcranial and remote treatment, in order to inform on best practice for a larger randomized placebo-controlled trial (RCT). METHODS: Twelve participants with idiopathic PD were recruited. Six were randomly chosen to begin 12 weeks of transcranial, intranasal, neck and abdominal PBM. The remaining 6 were waitlisted for 14 weeks before commencing treatment. After the 12-week treatment period, all participants were supplied with PBM devices to continue home treatment. Participants were assessed for mobility, fine motor skills, balance and cognition before treatment began, after 4 weeks of treatment, after 12 weeks of treatment and the end of the home treatment period. A Wilcoxon Signed Ranks test was used to assess treatment effectiveness at a significance level of 5%. RESULTS: Measures of mobility, cognition, dynamic balance and fine motor skill were significantly improved (p<0.05) with PBM treatment for 12 weeks and up to one year. Many individual improvements were above the minimal clinically important difference, the threshold judged to be meaningful for participants. Individual improvements varied but many continued for up to one year with sustained home treatment. There was a demonstrable Hawthorne Effect that was below the treatment effect. No side effects of the treatment were observed. CONCLUSIONS: PBM was shown to be a safe and potentially effective treatment for a range of clinical signs and symptoms of PD. Improvements were maintained for as long as treatment continued, for up to one year in a neurodegenerative disease where decline is typically expected. Home treatment of PD by the person themselves or with the help of a carer might be an effective therapy option. The results of this study indicate that a large RCT is warranted.

Patient Reported

Many people living with Parkinson’s Disease (PD) face issues with healthcare services, including delays in diagnosis and treatment, as well as limited access to specialized care, including rehabilitation programs. Non-motor and motor signs and symptoms typically observed in people with PD, such as tremor, rigidity, postural instability, bradykinesia, and freezing are particularly disabling and have been associated with falls, fractures, hospitalizations, and a worse quality of life. Baduanjin Qigong (BDJ) programs have been proven potentially effective in improving physical outcomes and reducing the incidence of falls in PD. The aim of this case report, proof-of-concept, study was to explore the adherence, feasibility, acceptability, and potential efficacy of a BDJ program offered via telerehabilitation in people with PD living in the community. Two participants performed semi-supervised exercise sessions at home, twice a week (over eight weeks) using the TeraPlus platform. Adherence, adverse events, and feasibility (technical implementability), acceptability (patient satisfaction), patient-reported, self-reported, and performance outcomes were measured. Results were based on single-subject descriptive data, minimal detectable change, and anchor-based minimally important difference. Our findings suggest that the intervention seems feasible with no major technical issues or adverse events, and high adherence; acceptable (patient satisfaction); and potentially effective to improve markers of walking performance (gait speed, balance), and quality of life (activities of daily living, mobility).
