Transcranial Direct Current Stimulation and Dual Tasks — Tdcs&DT  

Parkinson Disease Clinical Trial

Official title: "Transcranial Direct Current Stimulation and Dual Tasks in Parkinson's Disease-tDCS&DT in PD"

Status Recruiting

Clinical Trial Summary

The project aims to evaluate the clinical and biological effects on patients with Parkinson's disease of an innovative treatment characterized by the use of transcranial Direct Current Stmulation (tDCs) with Dual Task (DT), i.e. including the performance of motor activities in conjunction with the request of cognitive performance, such as executive functions (creative flexibility, working memory and divided attention).

Randomized controlled, double-blind, non-pharmacological study using device.The project involves the enrollment of 30 patients.Participants will be randomized into 2 groups: 15 / group and will carry out activities in DT associated with tDCS real (test group) or sham (control group). Each will carry out 12 rehabilitation sessions (2 / week) of 30 minutes. A follow-up is foreseen for all 12 weeks after the end of the treatment.

Patients will undergo, at baseline (T0), at the end of the session (T1) and at 12 weeks (T2), a motor and a cognitive profile, moreover a blood sample will be taken.

The project intends to improve the state of Parkinson's patients both thanks to the type of protocol that associates DT and tDCS, and thanks to the verification of the treatment through personalized biological analyzes. In detail, improvement in clinical performance, space-time variables in gait and cognitive tests are expected; the variability of synaptic and pathological markers will serve to verify the effect of the treatment.

Clinical Trial Description

Parkinson's disease (PD) is a neurodegenerative disease characterized by motor symptoms such as tremor at rest, rigidity, bradykinesia, postural instability and cognitive deficits A growing number of studies show that transcranial direct current electrical stimulation (tDCS), a low-cost, non-invasive brain stimulation method, could potentially become a clinical tool for rehabilitation of patients with Parkinson's disease.

Furthermore, some studies have shown that walking deficit in patients with Parkinson's disease is exacerbated by adding a dual cognitive or motor task. Daily activities require walking while simultaneously performing cognitive and / or motor tasks, such as talking to a friend or carrying a glass of water. This is why there are Dual Task (DT) training programs for patients with Parkinson's disease. A recent systematic review and meta-analysis demonstrated that treatment in DT can be an effective method of improving walking in terms of walking speed and cadence, balance and other motor symptoms in patients with Parkinson's disease.

Future investigations are needed to determine stimulation characteristics and optimal dosage when combined with training in DT.

The present study aims to investigate whether the application of tDCS at the dorso lateral prefrontal cortex(DLPFC) region level can add significant improvements to the motor and cognitive profile in patients with Parkinson's disease.

Randomized controlled, double-blind, non-pharmacological study using device. The data will be collected at the Department of Neurorehabilitation Sciences of the Polyclinic Nursing Home in Milan.

The project involves the enrollment of 30 patients. Each patient will take part in the study after an overall assessment of the general medical conditions, in relation to the suitability for participation in the study, by the neurologist of the unit department of Neuromotor Rehabilitation.

Randomized quadruple-blind study in parallel groups, in which the therapist who will carry out the treatment and the patient will not be aware of the assignment to the group (experimental vs control). Participants will be randomized into 2 groups, using Research Electronic Data Capture (RedCap) software:15 / group and will carry out activities in DT associated with tDCS real (test group) or sham (control group). Each will carry out 12 rehabilitation sessions (2 / week) of 30 minutes. A follow-up is foreseen for all 12 weeks after the end of the treatment.

Patients will undergo, at baseline (T0), at the end of the session (T1) and at 12 weeks (T2), a motor and a cognitive profile, moreover a blood sample will be taken.

The project intends to improve the state of Parkinson's patients both thanks to the type of protocol that associates DT and tDCS, and thanks to the verification of the treatment through personalized biological analyzes. In detail, improvement in clinical performance, space-time variables in gait and cognitive tests are expected; the variability of synaptic and pathological markers will serve to verify the effect of the treatment. ;
