Influences of Balance Training With a Dynamometric Platform in Total Knee Arthroplasty (TKA_DP)

April 14, 2016 updated by: Sergio Roig Casasus, University of Valencia

Valoración de la Puesta en Marcha en Artroplastias Totales de Rodilla Mediante un Trabajo Postural en Plataforma Dinamometrica

Knee osteoarthritis produces degeneration and joint wear that greatly affects the patient's proprioceptive system increasing instability. After total knee arthroplasty intervention, it is recommended that the patient performs a rehabilitation procedure to minimize deficits caused by surgery. In this job it is essential to insist on the importance of recovering balance after total knee arthroplasty intervention, and assess a specifically designed protocol to restore its function. An intervention which includes a dynamometric platform as a training method was proposed. The randomized clinical trial compared a control group that performed balance exercises on parallel bars, unstable plates, ramps and stairs against an experimental group that included dynamometric platforms training as a differentiator.

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.

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)

Enrollment

69

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

65 years to 85 years (Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • The Result in Berg scale must be greater than 21, indicating a medium-low risk of falling.
  • the Result of the Mini-Mental State Examination must be equal or greater than 20, which means they do not have moderate or severe cognitive impairment.

Exclusion Criteria:

  • Patient does no accept sign the informed consent.
  • Patient with morphological alterations hip or ankle (also knee).
  • Patient that presents knee flexion out of the range between 70 ° and -20 ° because of the risk posed to suffer a fall.

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
Berg Balance Scale
Time Frame: Change from baseline (two weeks after intervention) to after four weeks of training
Balance among older people with impairment in balance function by assessing the performance of functional tasks from the total score achieved in the 14 items test
Change from baseline (two weeks after intervention) to after four weeks of training

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.
