Therapeutic Approaches for Subjects With Scapula Dyskinesis

June 24, 2019 updated by: National Taiwan University Hospital

Therapeutic Approaches for Subjects With Scapula Dyskinesis: Conscious Control, EMG Biofeedback Training, and Intensive Scapula-focused Intervention

The investigators will test whether conscious control with manual guides and video or EMG biofeedback will enhance 3-D kinematics of scapula in shoulder dysfunction subjects with different type of scapula dyskinesis. The investigators will also examine how correction of scapular orientation may affect the activation of associated muscles during various dynamic movements in these subjects.

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

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

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 50 years (ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Inclusion criteria:

  • At least three positive of five tests, including Neer's test, Hawkin's test, Empty can test, tenderness in tendon of rotator cuff and resisted external test.
  • Each patient will need a prescription of the physician or orthopedic surgeon for diagnosing impingement symptoms

Exclusion criteria:

- Shoulder pain onset due to trauma, a history of shoulder fractures or dislocation, cervical radiculopathy, degenerative joint disease of the shoulder, surgical interventions on the shoulder, or inflammatory arthropathy

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: Biofeedback group
After 1 minute of rest, participants will perform 6 trials of bilateral, active, weighted arm elevation in the scapular plane and a therapist classifies the scapular motion into specific patterns of scapular dyskinesis. After the evaluation of scapular dyskinesis, the kinematics and surface EMG (sEMG) data will be collected during 5 trials of the same arm movements and 3 selected exercises.
Other: Conscious control+biofeedback
In electromyography (EMG) biofeedback training, electronic equipment is used to reveal instantaneously certain physiological events.
ACTIVE_COMPARATOR: Conscious control group
Conscious correction of scapular orientation will be taught to the subjects in the manner described in previous studies. The starting position is determined in each individual by actively positioning the scapula between maximal upward and downward rotation, external and internal rotation, and posterior and anterior tilt. Scapular assistance test (SAT) is also conducted by passively assisting patients' scapula into appropriate position to correct scapula dyskinesis
Other: Conscious control
Conscious control of the scapula is important and can correct neuromuscular coordination as well as strength deficits. The strategy in learning control of scapula into normal orientation can be facilitated by manual guides and/or external cues

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
Shoulder complex kinematics
Time Frame: The scapular kinematics will be measured before scapular control and immediately after scapular control
Scapular orientation relative to the thorax is described using a Euler angle sequence of rotation about Zs (protraction/retraction), rotation about Y's (downward /upward rotation), and rotation about X"s (posterior/anterior tipping). Scapular elevation is defined as the vertical displacement of the scapular sensor during arm elevation. Humeral orientation relative to the scapula is described using a Euler angle sequence in which the first rotation represents the plane of elevation, the second rotation defines the amount of elevation, and the third rotation describes the amount of axial rotation.
The scapular kinematics will be measured before scapular control and immediately after scapular control
Shoulder associated muscular activities
Time Frame: The muscle activation will be measured before scapular control and immediately after scapular control
Full bandwidth sEMG data, captured by data acquisition software (AcqKnowledge, Biopac systems Inc., CA, USA)
The muscle activation will be measured before scapular control and immediately after scapular control

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Forward shoulder posture
Time Frame: After subjects are included in the study, the forward shoulder posture will be measured before scapular control, and be done within 2 hours.
The measurement of the distance between the posterior border of the acromion and the table
After subjects are included in the study, the forward shoulder posture will be measured before scapular control, and be done within 2 hours.
Pectoralis minor muscle length
Time Frame: After subjects are included in the study, the muscle length will be measured before scapular control, and be done within 2 hours.
The distance from the fourth rib to the coracoids process will be measured with FASTRAK system with accuracy of 0.08 cm. This distance (in centimeter) is divided by the subjects height and multiplied by 100. This results in a pectoralis muscle length index
After subjects are included in the study, the muscle length will be measured before scapular control, and be done within 2 hours.
