Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study investigated the combined effects of anodal tDCS and intensive motor training (MT) vs. sham stimulation with MT (control intervention) on grip strength, motor performance and functional use of the affected arm in population of chronic stroke patients.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

A growing body of evidence are available regarding the effectiveness of anodal transcranial direct current stimulation (tDCS) in patients with chronic hand motor impairment as a stroke consequence.

This study investigated the combined effects of anodal tDCS and intensive motor training (MT) vs. sham stimulation with MT (control intervention) on objective evaluation of fine and gross motor hand function using simulated activities of daily living (Jebsen-Taylor hand function test), grip strength, motor performance and functional use of the affected arm in this population of patients.

Patients with chronic hand motor deficits after stroke (\> 12 months) are randomly assigned to active stimulation or a control intervention arm in a double-blinded, sham-controlled, parallel design. Each group received intensive MT for 45 min/day, 5 days/week, for 2 weeks, which was preceded by 20 minutes of 2 milliampere of anodal tDCS over the ipsilesional M1 vs. sham tDCS.

Outcome measures are tested at baseline (T0), and after the intervention Day 1 (T1), after stimulation protocol completion Day 10 (T2) and 30 days later (T3).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Active treatment

Group of patients on active treatment will receive intensive motor training for 45 min/day, 5 days/week, for 2 weeks, which would be preceded by 20 minutes of 2 mA anodal tDCS over the ipsilesional motor cortex.

Group Type EXPERIMENTAL

tDCS (Endomed 482; Enraf-Nonius B.V.)

Intervention Type DEVICE

non-invasive brain stimulation with pair of electrodes with saline-soaked pads through which the direct current of intensity of 2 mA is delivered

Sham comparator

Group of patients on sham treatment will receive intensive motor training for 45 min/day, 5 days/week, for 2 weeks, which would be preceded by sham tDCS over the ipsilesional motor cortex.
