About this study
Official title: The Efficiency of the PNF Method in Assessing Functional Performance in Early Stage Patients Following Knee Arthroplasty
Background: Early rehabilitation following knee arthroplasty is an integral part of medical management which reduces the time of patient's stay at hospital and eliminates the risk of post-operative complications. The absence of consensus on the most efficient post-operative rehabilitation strategy and shortage of practices based on evidence lead to seek new therapeutic solutions. Therefore the goal of this study is to evaluate the efficiency of the PNF method in assessing functional performance in early stage patients following knee arthroplasty Material and methods: The study was conducted among 96 patients (66,34 years ±7,29) who were qualified to total knee arthroplasty. The patients were randomly divided into two groups. In the control group standard rehabilitation protocol was implemented while post-operative treatment in the study group based on PNF method. All the patients were tested on the day of admission to the hospital and after completing a 10-day rehabilitation program. Structural and functional parameters of the operated knee (muscle strength, range of motion, circuit measurements) as well as functional abilities (Staffelstein Score, Lequesne Index) were evaluated.
Key words: gonarthrosis, knee replacement, osteoarthritis, PNF method
Read the detailed description
Involution changes of the human body are characteristics of aging. A decrease in physical activity as well as increased life expectancy can be a factor in the development of many pathological changes in the movement system resulting in increase in the number of people with diagnosed osteoarthritis (OA) [1]. Epidemiological studies indicate that osteoarthritis affects up to 40 million people in Europe [2], including 10% of men and 13% of women above 60 years of age with knee degenerative changes [3]. It is estimated that in Poland over 8 million people suffer from osteoarthritis, out of which 25% have gonarthrosis [4]. Osteoarthritis detracts from the quality of life and leads to malfunction and this is therefore necessary to early implement prevention and treatment actions which allow for keeping functional performance and protection against development of destructive changes [5].The study will be conducted in Cracow Rehabilitation and Orthopedics Centre. The study group will be qualified to the total knee arthroplasty due to pain caused by advanced knee osteoarthritis. . The patients will be randomly divided into two groups which differed in the type of a 10-day treatment model used after the operation.
In the control group standard rehabilitation protocol will be used in patients following TKA, which is mainly based on activities in open chains (passive exercises with continuous passive motion (CMP) device, active exercises, isometric, active resistance, patella mobilization, deep tissue massage, verticalization and gait relearning). Treatment in the study group will be conducted with PNF method with a use of indirect training based on irradiation phenomenon. The program included: proprioceptive stimulation of the operated limb, improving trunk stabilization and active control, active foot training, muscle strength facilitation of lower limbs in closed kinematic chain with considering periarticular stabilization within the operated knee joint as well as exercises improving mobility of the operated knee, verticalization and locomotion with emphasis on the stance phase.
In this study, an attempt will be made to analyze treatment effects on parameters assessing function of the knee joint and functional abilities in daily living with a use of a classic rehabilitation protocol and PNF method in patients following TKA. To evaluate efficacy of the therapy all the patients will be tested on the day of admission to the hospital and on the last day of the treatment. Structural and activity parameters of the operated knee joint will be evaluated, such as muscle strength (6-point Lovett scale), range of motion (digital inclinometer) and circuits measurement (centimeter). Circuits were measured on the level of the knee joint articular space, 10 cm (Thigh I) and 20 cm (Thigh II) above the articular space as well as on the level of lower leg (the widest point). Scales based on a subjective evaluation, such as Staffelstein Score and Lequesne Index will be performed to assess functional abilities.

Questions about this trial
What is this clinical trial studying?
A study testing PNF method and Standard rehabilitation in people with Knee Arthroplasty, run by Jagiellonian University at 2 sites in Poland.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 28 Dec 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in Poland. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
muscle strength test (time frame: baseline). The study lists 7 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04686071, which also lists 8 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Dec 2020.
