Brief Summary

Pain is an under-reported but prevalent symptom in Parkinson´s Disease (PD), impacting patients' quality of life. Both pain and PD conditions cause cortical excitability reduction, but non-invasive brain stimulation is thought to be able to counteract it, resulting also effective in chronic pain conditions. The investigators in the present project aim to evaluate the efficacy of a novel brain stimulation protocol in the management of pain in PD patients during the ON state. The investigators hypothesize that active transcranial direct current stimulation (a-tDCS) over the Primary Motor Cortex (M1) can improve clinical pain and its central processing features.

Outcome Measures

Primary Outcomes (10)

  • Change in King´s Parkinson´s Disease Pain Scale score

    Parkinson´s Disease specific scale that evaluates the localization, frequency, and intensity of pain. It has 14 items distributed in 7 domains: 1. Musculoskeletal Pain; 2. Chronic Pain; 3. Fluctuation-related Pain; 4. Nocturnal Pain; 5. Oro-facial Pain; 6. Discoloration, Oedema/Swelling Pain; 7. Radicular Pain. Each item is scored by severity (0, none to 3, very severe) multiplied by frequency (0, never to 4, all the time) resulting in a subscore of 0 to 12, the sum of which gives the total score with a theoretical range from 0 to 168, with higher scores indicating more severity and frequency of pain.

  • Change in Brief Pain Inventory score

    It contains 15 items, including 2 multi-item scales to measure the intensity of pain and its impact on the function and welfare of patients. It also presents open questions to assess the localization of pain and the treatment used for its management, just as its effectiveness. Scores oscillate from 0 to 110, with higher scores indicating more pain and more impact on function and welfare of patients.

  • Change in Conditioned Pain Modulation

    Assesses the descending pain modulatory system. The Pain Pressure Threshold will be assessed in the middle of the distal phalanx of the thumb with ta handheld algometer, corresponding to the first test stimulus. Afterward, the patient will immerse the contrary hand up to the wrist into stirred ice-cold water (0-4º) maintaining it for 3 minutes, corresponding to the conditioning stimulus. If the pain is unbearable before the 3 minutes, the patient will be able to remove his/her hand. Immediately after removing the hand, a second Pain Pressure Threshold measure will be performed in the same place as the first one, corresponding to the second test stimulus. After 1-minute rest, a third Pain Pressure Threshold will be measured to assess the Conditioned Pain Modulation residual functioning.

  • Change in Temporal Summation

    Represents excitatory modulation processes. It will be generated through the application of 10 pulses of the handheld pressure algometer over the middle of the distal phalanx of the thumb with the intensity of the Pain Pressure Threshold, previously calculated. In each pulse, pressure intensity will be increasing at a rate of 2 kg/s over the previously determined Pain Pressure Threshold intensity, leaving an interstimulus interval of one second according to the optimal method reported for inducing Temporal Summation with pressure pain. Before the first pressure pulse, subjects were taught to use a verbal numeric pain rating scale to rate the pain intensity of the first, fifth, and 10th pressure pulses. The verbal numeric pain rating scale ranged from 0 ("no pain") to 10 ("the worst possible pain").

  • Changes in Pain Pressure Threshold

    Two Pain Pressure Thresholds will be measured by a handheld algometer, one over the most painful area (peripheric hyperalgesia) and the other one over the middle of the distal phalanx of the thumb (central hyperalgesia). The Pain Pressure Threshold will be applied with the algometer perpendicular to the skin increasing at a rate of 1 kg/s until the first sensation of pain. 3 measures with 30-seconds rest between them will be performed, taking the average as Pain Pressure Threshold.

Study Arms (2)

Active Transcranial Direct Current Stimulation

EXPERIMENTAL

Active Transcranial Direct Current Stimulation (a-tDCS) will be applied over the Primary Motor Cortex during 10 sessions of 20 minutes at 2 milli amps.

Device: Active Transcranial Direct Current Stimulation

Sham Transcranial Direct Current Stimulation

SHAM COMPARATOR

Sham Transcranial Direct Current (s-tDCS) will be applied over the Primary Motor Cortex during 10 sessions of 20 minutes.

Device: Sham Transcranial Direct Current Stimulation

Interventions

The Starstim tDCS® stimulator will be used by an experienced physical therapist to transfer direct current by a saline-soak pair of surface sponge electrodes (35cm2). The anode electrode will be placed over C3 (EEG 10/20 system) and the cathode electrode over the contralateral supraorbital area (Fp2), in order to enhance the excitability of M1 (32). Regarding the stimulated hemisphere, contralateral M1 will be stimulated in patients with asymmetric pain and the dominant (contrary to the dominant hand determined by the Edinburgh Handedness Inventory) in patients with symmetric pain, due to the widespread changes induced by tDCS in other cortical areas, including contralateral M1. A constant current of 2 milli amps intensity (subthreshold intensity) will be applied for 20 min, with 30 seconds of ramp-up and 30 seconds of ramp-down.

Active Transcranial Direct Current Stimulation

The electrodes will be placed in the same positions as for M1 stimulation, but only applying ramping active current for 30 seconds in the beginning and at the end of the procedure for a reliable blinding.

Masking Details
Triple-blind criteria will be achieved by identic collocation of the electrodes in both groups and by activating the "double-blind" option in the Starstim tDCS® Software (Neuroelectrics Inc, Barcelona, Spain) that allows concealing the protocol by writing a neutral number. The evaluator, not allowed to stay in the same room while interventions, will conceal the protocols with the neutral number and the therapist will read it in the envelope, ignoring which number coincides with each intervention. At the end of the full treatment, patients will be asked whether they received active or sham stimulation, to assess the blinding success. Patients recruited will not meet in waiting rooms to avoid them to comment on their experience during the protocol. The statistician will be also blinded through the mentioned neutral numbers. Unblinding will be permissible when any event could suppose a risk for the patient's health.

Intervention Model
PARALLEL
Model Details: This study will be a triple-blinded experimental longitudinal prospective randomized controlled trial with a parallel design. The randomization will be realized through the "GraphPad" software by an independent investigator. All the participants who fulfill the inclusion criteria and have none of the exclusion ones will be randomly allocated into two groups: active-tDCS (a-tDCS) or sham-tDCS (s-tDCS). Allocation concealment will be ensured by the inclusion of the assigned group in closed opaque envelopes that will be opened at the time of the intervention.
