Electro-acupuncture for Gait and Balance in Parkinson's Disease

November 8, 2017 updated by: Hong Lei, University of Arizona

Objective Assessment of Electro-acupuncture Efficacy for Gait and Balance in Patients With Parkinson's Disease

Gait and balance disorders, key contributors to fall and poor quality of life, represent a major therapeutic challenge in Parkinson's disease (PD). Despite the widespread use of acupuncture in recent years in PD, its efficacy remains unclear, largely due to methodological flaws and lack of high quality studies using objective outcome measures. In a patient and assessor-blind pilot study, investigators objectively assess the efficacy of electroacupuncture (EA) for gait and balance disorders using body-worn sensor technology in patients with PD.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

In this study, investigators employee objective innovative body-worn sensor technologies to assess potential mobility-associated outcomes of PD. Investigators compare acute changes in gait and balance that occurred after repeated administration of two interventions: A specific real EA and a sham EA. The design of the experiments uses a control that accounts for both placebo and possible some active components of a generalized needle-insertion-based procedure. By using a sham control, the investigators were able to more fully test whether the specific EA intervention could lead to changes in objective gait and balance parameters, or subjective self-reported improvements that are beyond placebo induced effects and the natural course of the disease.

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

55 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. Community-dwelling men or women ages 55 years or older with diagnosis of PD;
  2. patients who have the ability to walk 20meters without walking assistance; and
  3. patients who are stable without anti-PD medication(s) change for at least 1 month. The PD diagnosis was made by movement disorder specialists based on the UK Brain Bank criteria and supported by DaTscan (Ioflupane I 123 injection) when possible.

Exclusion Criteria:

  1. patients who have received previous acupuncture;
  2. patients who have had DBS;
  3. patients with any clinically significant medical condition, psychiatric condition, drug or alcohol abuse, or laboratory abnormality that would, in the judgment of the investigators, interfere with the ability to participate in the study; and
  4. patients with non-PD related gait disorders.

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.
EXPERIMENTAL: Real EA
Real EA as intervention is performed at the selected standard acupuncture points and "De-qi" is achieved with needle manipulation before electric stimulation is delivered.
Procedure: Electroacupuncture
Acupuncture is an alternative medicine methodology that treats patient by various techniques including inserting small, thin needles at specific points of body. Electroacupuncture (EA), like the name implies, combines classical acupuncture and low electric current running through the needles, which are often used to enhance a treatment.
Other: Body-worn sensor technology
Three-dimensional acceleration and angular velocity of shanks, thighs and the trunk were measured using wearable sensors each included a triaxial accelerometer and a triaxial gyroscope (LEGSys™ and BalanSens™ - BioSensics, Boston, MA)
SHAM_COMPARATOR: Sham EA
Sham EA as intervention is performed for the control group at non-acupuncture points without needle manipulation. The electric stimulation in sham acupuncture was performed in a similar fashion to the real EA.

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.
