Prehabilitation Physical Activity in Persons With Osteoarthritis (PrehabOA)

September 12, 2016 updated by: Helena Gapeyeva, University of Tartu

Prehabilitation Physical Activity: Relationship With Muscle Function, Postural Stability and Postoperative Recovery in Persons With Osteoarthritis

Knee joint osteoarthritis (OA) reduces functional mobility and performance of daily tasks such as rising from a chair. Therefore interventions aimed at improving muscle strength and sit-to-stand task performance are very important for these patients. The effect of exercise programs, including home exercise programs (HEP), on muscle strength, joint pain and function is well known and widely researched, yet not many studies have investigated the effect of an HEP on electromyographic activity (EMG) of muscles when performing everyday tasks, such as rising from and sitting on a chair. The aim of this study was to investigate effect of prehabilitation in women with severe knee joint OA scheduled for knee joint arthroplasty (TKA).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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

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.
  • Phase 4

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

50 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Description

Inclusion Criteria:

  • For OA patients: patients with severe knee joint OA undergoing unilateral total knee arthroplasty (TKA)
  • for controls: pain of joints more than 20/100 mm by VAS

Exclusion Criteria:

For both groups:

  • previous total joint arthroplasty of lower limbs

How is the study designed?

Design Details

  • Primary Purpose: Prevention
  • Allocation: N/A
  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

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: Home Exercise Program
8- week therapeutical exercise program performing at home for women with knee joint osteoarthritis
Other: therapeutical exercises
Participants of experimental group performs daily an 8-week home therapeutical exercise program. Exercises are periodized by weeks (1-8 weeks). The aim of program is the leg muscle strengthening using an elastic band (Thera-Band, System of Progressive Exercise, USA), body balance training, and leg muscle stretching.

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
Muscle electromyographic (EMG) activity
Time Frame: up to 12 months
Electromyographic (EMG) activity of thigh muscles during gait and sit to stand task (amplitude, mV)
up to 12 months

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
Knee joint pain intensity
Time Frame: up to 12 months
Self-reported knee joint pain intensity measured by visual-analogue scale (VAS) (in mm: "0 mm" - no pain and "100 mm" - extreme pain)
up to 12 months

Time Frame: up to 12 months
Self-reported functional status measured by Knee Injury and Osteoarthritis Outcome Score (KOOS) - Symptoms, Pain, Daily Living Activity, Sport and Recreational Activity. Quality of Life. Maximum is 100 points (complains are absent) and minimum is 0 points (extreme complains)
up to 12 months
Sit to Stand test
Time Frame: up to 12 months
