About this study
Official title: TAME-PD - Physical Therapy, Atomoxetine and, Methylphenidate, to Enhance Gait and Balance in Parkinson's Disease: A Single Center, Randomized Pilot Study
Gait and balance problems are a significant source of disability in patients with Parkinson disease. Physical therapy remains one of the main treatments. On the other hand some medications, such as methyphenidate and atomoxetine, have been tried with promising results. The outcomes in gait and balance in Parkinson disease after a combination of physical therapy and the medications mentioned above have not been explored yet. The investigators want to evaluate whether the addition of medication, either low dose of methylphenidate or atomoxetine, to physical therapy will achieve improvement in gait and balance in Parkinson disease more than physical therapy alone. The investigators propose a pilot, single center, rater blind, prospective randomized trial. 2-arm-parallel group, intention-to-treat analysis.
Read the detailed description
Gait impairment and postural instability constitute major sources of disability in Parkinson disease (PD). Increased level of dependence in activities of daily living and augmented risk of falling are the main consequences. About 87% of patients experience at least one fall during their illness, 65% an injury that requires evaluation in an emergency room, and up to 33% sustain one or more fractures.
Pedunculopontine nucleus, locus ceruleus, frontal brain cortex, and striatum play a critical role in gait and balance, with dopamine, noradrenaline and acetylcholine as the main neurotransmitters. Therefore, increased availability of dopamine in the nigrostriatal pathway, and enhanced disposal of central noradrenaline and acetylcholine in the locus ceruleus can in theory, contribute to improvement .
Methylphenidate and atomoxetine are dopamine and noradrenaline reuptake inhibitors approved for the treatment of attention disorders. Interestingly, growing literature suggests a promising role of these medications in gait and balance in PD. Three open-label studies reported efficacy of methylphenidate in gait impairment in patients with PD. Auriel et al used a single 20 mg dose of methylphenidate in 23 patients and found an improvement in gait speed, stride time variability, and timed gait. In a second study, 5 patients received a single 10-mg dose of methylphenidate and improvements were noted in total walking time, total freezing time, number of freezing episodes, and nonfreezing walking time. Another study, which evaluated a 50 to 80 mg dose of methylphenidate over 3 months in 17 patients undergoing concomitant deep brain stimulation, found an improvement in both timed gait and in the number of freezing episodes.
However, the only randomized clinical trial with methylphenidate showed a different result. Twenty-three subjects with PD and moderate gait impairment were screened for this 6- month, placebo-controlled, double-blind study. Subjects were randomly assigned to high dose of methylphenidate (maximum, up to 80 mg/day) or placebo for 12 weeks and crossed over after a 3-week washout. The primary outcome measure was change in a gait composite score obtained through GAITrite (a system that was developed to measure and record temporal and spatial parameters of gait by using a walkway approximately 3 meters long with grids of embedded, pressure-sensitive sensors connected to a personal computer). Seventeen patients completed the trial. There was no change in the gait composite score or any of the secondary or exploratory variables such as fatigue, freezing, depression and daily sleepiness at 12 weeks; however, some improvement was noted in the early phase of the study.
The discrepancy between the results of the open label studies and the randomized study may be explained by dose of methylphenidate substantially higher in the RCT compared to the first two open-label studies. Whereas patients in the RCT received at least 65 mg/day, patients in the first two open-label studies received 10-20 mg/day. It is been suggested that the efficacy of methylphenidate and atomoxetine varies according to the dose administrated. The complex pharmacodynamic of dopamine and noradrenaline reuptake inhibitors in the presence of other dopaminergic therapies such as Levodopa or dopamine agonist, can elicit differences in response regarding the administered dose . During the early phase of the RCT when a trend improvement was noted, smaller doses of methylphenidate were being used as the patients were being titrated to their final dose. Low chronic doses of methylphenidate have not been tested to improve gait and balance in PD in any trial.
In the one pilot study thus far evaluating atomoxetine for gait freezing, a trend towards improvement in the gait and balance scale (GABS) was noted. However, this study was underpowered as only five patients participated in the study .
Simultaneously, diverse modalities of physical therapy (PT) have shown improvement in gait and balance in PD. A systematic review from Cochrane database concluded that different physiotherapy interventions were better than placebo over three months, in terms of velocity, two- or six-minute walk test, step length, Timed Up \& Go, Functional Reach Test, Berg Balance Scale and clinician-rated UPDRS. The grade of improvement varied depending on the intervention and outcome measure, ranging from 10 to 30%.
To the best of the investigators' knowledge, the combination of medication and physical therapy has never been evaluated previously in gait and balance in PD.

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 9 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Balance Evaluation (time frame: 12 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02879136, which also lists 18 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Jan 2026; AzTrials last refreshed its copy on 7 Nov 2026.
