Official title

Transcranial Direct Current Stimulation (tDCS) to Improve Motor Function and Motor Fatigue in Parkinson's Patients

Overview

The investigators hypothesize that multi-session anodal tDCS (atDCS) of the left primary motor cortex (M1) will induce long-lasting effects in improving motor function and reducing motor fatigue and fatigability in PD patients.

Detailed description

Parkinson's disease (PD) is the fastest growing and second most common neurodegenerative disease (after Alzheimer's disease) and affects approximately one million people in the United States. Impaired motor function is one of the cardinal features of PD. One of the diagnostic criteria for PD is bradykinesia (slowness of movement). In addition to bradykinesia, PD patients also suffer from increased motor fatigue and motor fatigability. In the body of fatigue research, the term "motor fatigue' usually refers to the general sensation of tiredness or of difficulty in initiating physical activity experienced over several days to weeks. This is often assessed by questionnaires completed by the subject. The term 'motor fatigability' refers to difficulty in maintaining physical activity at a desired level (Lou, 2009). This is often assessed quantitively in a laboratory setting. Motor impairments, motor fatigue, and motor fatigability affect quality of life in patients with Parkinson's disease.

Transcranial direct current stimulation (tDCS) is a noninvasive and safe brain stimulation technique that has been shown to be effective in improving motor function in subjects with Parkinson's disease. During tDCS, low-voltage, low amplitude current is passed through a pair of surface electrodes placed over the areas of brain of interest.

The specific aim of this study is to examine if atDCS to M1 at 2 milliamps (mA) for 20 minutes daily for 5 days will improve motor function and reduce motor fatigue and fatigability in PD patients. The study will examine if the effects may last for two weeks.

Interventions

  • Device transcranial direct current stimulation (tDCS)
    2 mA will be administered for 5 consecutive days for a duration of 20 minutes with electrode placement at the left dorsolateral prefrontal cortex.
  • Device Sham (No Treatment)
    For 30 seconds, the patient will experience a ramp up of the stimulation, after which point no stimulation will be transmitted for the remainder of the session. This will be administered for 5 consecutive days for a duration of 20 minutes with electrode placement at the left dorsolateral prefrontal cortex

Primary outcome measures

  • Finger and Toe-Tapping on KinesiaOne Device [Time frame: 30 minutes; pre-test during the second research visit, post-test on 6th research visit after 5 consecutive days of tDCS, a follow up test on the 7th research visit, 7 days after last tDCS session and 8th visit 14 days after last tDCS session]
Secondary outcome measures (5)
  • Montreal Cognitive Assessment (MOCA) [Time frame: 8 minutes; pre-test during the second research visit.]
  • The Multidimensional Fatigue Inventory (MFI) [Time frame: 5 minutes; pre-test during the second research visit, post-test on 6th research visit after 5 consecutive days of tDCS, a follow up test on the 7th research visit, 7 days after last tDCS session and 8th visit 14 days after last tDCS session]
  • Center for Epidemiological Studies Depression Scale (CES-D). [Time frame: 5 minutes; pre-test during the second research visit, post-test on 6th research visit after 5 consecutive days of tDCS, a follow up test on the 7th research visit, 7 days after last tDCS session and 8th visit 14 days after last tDCS session]
  • McGill Quality of Life (QOL) Scale [Time frame: 1 minute; pre-test during the second research visit, post-test on 6th research visit after 5 consecutive days of tDCS, a follow up test on the 7th research visit, 7 days after last tDCS session and 8th visit 14 days after last tDCS session]
  • MDS-UPDRS Part II (patient self-report) [Time frame: 10 minutes; pre-test during the second research visit, post-test on 6th research visit after 5 consecutive days of tDCS, a follow up test on the 7th research visit, 7 days after last tDCS session and 8th visit 14 days after last tDCS session]
