Outcome Measures

Primary Outcomes (1)

  • Experimental pain intensity measured on a visual analogue scale (0-100)

    4 hours

Secondary Outcomes (2)

  • effect of Ritalin on auditory sensitivity, measured by the response to different auditory stimulations

    4 hours

  • pain intensity (NPS 0-100) in response to thermal stimuli and the measures of the auditory tests.

    4 hours

Study Arms (2)

methylphenidate hydrochloride

EXPERIMENTAL

The study will include two sessions which will be conducted at the same time of the day, one week apart from each other. Each session will last approximately 6 hours. In each session subjects will be exposed to baseline experimental pain models and auditory tests. Then they will receive either one MP SR 20 mg tablet or an identical looking placebo.

Drug: methylphenidate hydrochloride

Sugar pill
