Non-Specific Effects of Manual Therapy

Non-Specific Effects of Manual Therapy: A Mixed-Methods Investigation of Contextual and Social Interactions

The mechanism responsible for improvement following manual physical therapy techniques is unknown. Previous studies have indicated both biomechanical and neurophysiologic effects which may be responsible for clinical changes observed. Yet, other studies report clinical changes following sham interventions. Through a mixed-methods design, this study aims to gain more understanding of the social and contextual factors that may be related to the improvement often observed following manual therapy techniques.

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

A convenience sample will be utilized to obtain subjects. Subjects will be given a brief questionnaire to identify possible contraindications for manual therapy treatment techniques and exclude individuals if necessary. Subjects will be randomized into one of eight groups (three variables, each with two conditions including: therapist gender match/mismatch, lab coat worn/not worn, detailed explanation/colloquial conversation about the technique) and participate in neurodynamic testing for the upper quarter via the Upper Limb Provocation Test. Subjects who are determined to be positive for one or more extremities will receive a sham thoracic spine manipulation technique. After application of the technique, previously positive limbs will be retested. Individuals who respond favorably to the sham technique upon reassessment will participate in an exit interview with open-ended questions in attempt to gain more insight into the factors which may have influenced their neurodynamic mobility improvement.

Study Type

Enrollment (Actual)

Enrollment

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

18 years to 70 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

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
Change in Upper Limb Provocation Test (ULPT)
Time Frame: Baseline and Immediately Post Intervention
Subjects will lie on their back with their shoulder slightly off the edge of a treatment table. The investigator will sidebend the subjects neck away from the extremity being tested and gradually move the extremity into the following positions: scapular depression, shoulder 90 deg abduction, shoulder 90 deg external rotation, forearm supination, wrist/finger extension, and elbow extension. The investigator will assess for symptoms at each phase throughout the test. At the onset of symptoms, sensitization maneuvers will be completed to determine if the origin of the symptoms is neurodynamic in nature and not myofascial.
