Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Repetitive transcranial magnetic stimulation can alter nerve cell excitability, improve cerebral blood flow and metabolism, and is widely used in neuropsychiatric research. Studies have shown its efficiency and safety in treating anxiety disorders, however the senior patient group has not been adequately validated. The purpose of this study is to evaluate the effects of low-frequency repetitive transcranial magnetic stimulation on anxiety state in older patients with generalized anxiety disorder.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: rTMS
Patients are treated with repetitive transcranial magnetic stimulation (rTMS).
Device: Repetitive Transcranial Magnetic Stimulation
rTMS is applied using a transcranial magnetic stimulator with a figure-of-8 coil once per day for 10 consecutive days. rTMS is delivered to the right dorsolateral prefrontal cortex (DLPFC) at a frequency of 1 Hz for 20 minutes (1200 total pulses).
Other Names:
  • rTMS
Sham Comparator: sham-rTMS
Patients are treated with sham repetitive transcranial magnetic stimulation (sham-rTMS).
Device: Sham Repetitive Transcranial Magnetic Stimulation
Sham-rTMS is performed in the same way as the treatment group except that the coil is rotated 90° away from the scalp.
Other Names:
  • sham-rTMS

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Differences in HAMA scores after 10 sessions of rTMS/sham-rTMS between two groups.
Time Frame: baseline; 10 days
The HAMA scale consists of 14 items, each with a score ranging from 1 to 4, for a total score ranging from 14 to 56, and the degree of anxiety correlates positively with the score.
baseline; 10 days

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
