About this study
Official title: High Force Resistance Training and Dopamine Replacement Effects on Hypokinesia in Parkinson Disease
Parkinson disease is a degenerative neurologic condition characterized by slowness of movement, tremor, and loss of balance control. It results in significant degrees of disability for affected individuals. Exercise and medication management are two treatments frequently used to treat Parkinson disease, and although some individuals benefit from these treatments, by what effect exercise works is presently not known. We will examine muscle structure and movement control responses to strengthening exercises and compare them to the therapeutic response observed as a result of medication intake. This process will allow us to better understand the mechanisms underlying the therapeutic effects of strengthening exercise for persons with Parkinson disease.
Read the detailed description
Idiopathic Parkinson disease (IPD) is the model movement disorder to explore the motor function of the basal ganglia. (Morris ME, 2005) Alterations in the output of the basal ganglia lead to reductions in muscle force output and movement amplitude while inactivity and impaired mobility contribute to the loss of muscle size and strength.
Collectively these factors lead to reductions in the size and speed (hypokinesia) of functional movements such as gait. Hypokinesia during gait initiation and gait are biomechanical events that can precipitates movement deficits such as bradykinesia and falls. Previous studies have suggested that resistance training is beneficial in the management of persons with PD. Although anatomic, behavioral, and mobility related improvements have been demonstrated with resistance training intervention, it is unclear if the observed changes are derived solely from peripheral musculoskeletal changes or from central nervous system mediated alterations in force output and movement amplitude. The responsiveness of muscle force, movement amplitude, and hypokinesia to the CNS mediated effects of dopamine replacement provide a model system to which the effects of resistance training can be compared. In order to examine this question, we plan to conduct a controlled trial to rigorously examine the effects of high force resistance training on muscle structure, muscle force output, and hypokinesia in persons with moderate IPD and in the process, characterize the potentially differential effects of resistance training effects and dopamine replacement. This study assembles a team of investigators with experience in high force resistance training, measurement of the biomechanical and clinical balance function in persons with PD, and the statistical analysis expertise. Persons with IPD will be recruited, examined, and if they meet the inclusion criteria will be randomly assigned to one of two groups (experimental or standard care control). A battery of tests including muscle structure, muscle force production, and measures of hypokinesia and will be assessed on and off dopamine replacement medication both prior to and after a 12 week resistance training intervention. The first specific aim of the study is to determine if high force resistance training results in improvements in muscle structure, muscle force output, and hypokinesia in persons with moderate IPD. The second specific aim is to characterize and compare any differential effects of high force resistance training and dopamine replacement on muscle force output and hypokinesia in persons with moderate IPD. We hypothesize that dopamine replacement and resistance training will interact to improve muscle force output and reduce hypokinesia. In addition, we hypothesize that examination of kinematic patterns during gait initiation will reveal differential effects on lower extremity hypokinesia. The results of this study will help to better understand the differential contributions of resistance training and dopamine replacement on hypokinesia in persons with PD.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Resistance Exercise via Negative Eccentric WorkBehavioural
High intensity resistance training delivered 2-3 times per week for 12 weeks
Standard care exercise trainingBehavioural
Evidence based exercise training (resistance training, aerobic training, flexibility training) 2-3 times per week for 12 weeks.
| Study group | Role | What they receive |
|---|---|---|
| High force LE resistance training | Experimental | High force lower extremity resistance training + Standard exercise care. The high force lower extremity resistance training group will participate in a 3 day per week progressive eccentric ergometry program that will be gradually increased over 3 weeks from 5-20 minutes per day and remain at that duration for the next 9 weeks. In addition, they will engage in exercises including moderate intensity aerobic training, concentric upper extremity resistance training and stretching (axial mobility exercises). Receives: Behavioral: Resistance Exercise via Negative Eccentric Work |
| Standard Care Control Group | Active comparator | Standard care exercise group: The standard care control group is an "active control group", i.e., individuals who will engage in our standard of care (an evidence based exercise program). These exercises include moderate intensity aerobic training (15 minutes), concentric upper extremity resistance training (5-10 minutes), balance training (5 minutes), and stretching (axial mobility exercises-5-10 minutes). Receives: Behavioral: Standard care exercise training |

Questions about this trial
What is this clinical trial studying?
A study testing Resistance Exercise via Negative Eccentric Work in people with Parkinson Disease, run by University of Utah at 1 site in United States.
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 1 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 21 Sep 2011. 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.
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?
Hypokinesia as measured by movement kinematics and kinetics (time frame: Pre intervention and post intervention). 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 NCT00665184, which also lists 5 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 21 Sep 2011.
