Relaxation Treatment in Total Knee Arthroplasty

April 10, 2021 updated by: HANDE GUNEY, Hacettepe University

Effects of Progressive Muscle Relaxation Techniques on Pain, Sleeping Quality and Functional Levels After Total Knee Arthroplasty

Surgical techniques and treatment methods of the arthroplasty have been improved and the results after total knee arthroplasty (TKA) are generally good. However, some patients have suboptimal postoperative results with respect to pain and physical functioning and may not be satisfied with the results of their TKA. Psychological symptoms were found to be associated with these suboptimal results. The aim of the present study is to determine weather relaxation techniques had beneficial effects on pain, sleeping quality, functional status and physiological symptoms in TKA patients during their hospital stay.

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.

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.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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 to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

  • primary knee osteoarthritis, Female Patients who are scheduled for unilateral Total Knee Arthroplasty surgery, were included in the study.

Exclusion Criteria:

  • having a previous knee or hip surgery or fracture, diagnosis of rheumatoid arthritis, severe obesity (BMI>40 kg/m2), sensory and motor disorders in the operated limb, inability to understand pain assessment.

  • Masking: Single

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.
Active Comparator: Relaxation Treatment
Relaxation treatment (RT) is applied additional to standard physiotherapy treatment. RT includes 8 sessions (2 times a day, for four days after surgery) of relaxation exercises.
Other: Standard Exercises
The physiotherapy protocol is applied under the supervision of the same physiotherapist within a progressive manner immediately after surgery. Continued passive range of motion is applied twice a day starting with 45º of knee flexion range of motion and increased gradually as tolerated. All patients performed same isometric, isotonic and active exercises. Patients were instructed to bear weight as tolerated on the postoperative day 1
Other Names:
  • Relaxation Treatment
Active Comparator: Standard Exercises
Standard postoperative rehabilitation program is applied to Control Group. Knee-based exercises were undertaken in supine (active- assisted knee flexion using a bandage, inner range quadriceps contractions, and straight-leg raises), seated (active-assisted knee flexion using the contralateral limb and inner range quadriceps contractions), and standing (hip and knee flexion, active hamstring curls, lunges on a step, hamstring stretches) postures.
Other: Relaxation Treatment
Relaxation Group recieve progressive muscle relaxation exercises additional to the standard exercises. The relaxation exercises are applied two times a day till the discharge day starting on the postoperative day one. Progressive muscle relaxation included the relaxing of different muscle groups along with deep breathing. The maximal contraction period consist of the contraction of muscle groups around ankle, calf, knee, hip, lumbar, thoracic and cervical regions, shoulder, arm, forearm for 5 s and continued with a relaxation period for 30 s while focusing on breathing. These two periods ware repeated for each muscle groups and lasted approximately 30 min
Other Names:
  • Standard Exercises

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
Pain Level Change
Time Frame: Mean change from Postoperative day 1 to day 4 recorded
Visual analog scale
Mean change from Postoperative day 1 to day 4 recorded

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.

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.
