Armi e interventi
Gruppo di partecipanti / Arm |
Intervento / Trattamento |
---|---|
Sperimentale: Active Anodal HD-tDCS
Subject will receive one 20-minute session of active anodal HD-tDCS.
|
Subject will receive active anodal/cathodal and sham HD-tDCS in a randomized, counterbalanced order. Each stimulation session will be separated by at least one week to avoid carryover effects. For both active and sham HD-tDCS the electrodes will be placed over the primary motor cortex, at an intensity of 2mA.
|
Sperimentale: Active Cathodal HD-tDCS
Subject will receive one 20-minute session of active cathodal HD-tDCS.
|
Subject will receive active anodal/cathodal and sham HD-tDCS in a randomized, counterbalanced order. Each stimulation session will be separated by at least one week to avoid carryover effects. For both active and sham HD-tDCS the electrodes will be placed over the primary motor cortex, at an intensity of 2mA.
|
Comparatore fittizio: Sham HD-tDCS
Subject will receive one sham session of HD-tDCS
|
Subject will receive active anodal/cathodal and sham HD-tDCS in a randomized, counterbalanced order. Each stimulation session will be separated by at least one week to avoid carryover effects. For both active and sham HD-tDCS the electrodes will be placed over the primary motor cortex, at an intensity of 2mA.

Cosa sta misurando lo studio?
Misure di risultato primarie
Misura del risultato |
Misura Descrizione |
Lasso di tempo |
---|---|---|
Change in pain scales
Lasso di tempo: Measured for approximately 5 weeks
|
Determine whether anodal or cathodal hd-tDCS is effective in reducing pain in subjects with chronic musculoskeletal pain as measured by changes in the Visual Analogue Scale (VAS) for pain.
The VAS scale will be measured immediately before the hd-tDCS stimulation sessions and after the hd-tDCS stimulation sessions for each subject for the duration of their participation in the trial.
This outcome will also be measured at their baseline visit, and follow-up visit.

Measured for approximately 5 weeks

Misure di risultato secondarie
Misura del risultato |
Misura Descrizione |
Lasso di tempo |
---|---|---|
Change in cutaneous hyperalgesia/allodynia
Lasso di tempo: Measured for approximately 5 weeks.
|
To investigate whether treatment with active anodal hd-tDCS alters the phenomenon of central sensitization as indexed by cutaneous allodynia and hyperalgesia by measuring whether anodal tDCS changes the threshold for pain and perception as compared with sham and cathodal hd-tDCS.
The subject's pain threshold will be measured immediately before the hd-tDCS stimulation sessions and after the hd-tDCS stimulation sessions for the duration of their participation in the trial.
This outcome will also be measured at their baseline visit, and follow-up visit.
|
Measured for approximately 5 weeks.
