About this study
Official title: Effect of Pre-operative Patient Education Program on Functional Outcomes After Total Knee Arthroplasty
This study aims to evaluate the effect of preoperative patient education program on functional mobility, gait, postural control, and kinesiophobia level in subjects with TKA. Patients of both gender will be recruited unilaterally in the city of Florianopolis and referred by an orthopedist to the Physiotherapy Clinic of UDESC. They are divided into two groups: one that will receive verbal guidance and a booklet with related information such as your physical condition as well as signs and symptoms in the postoperative period and a group that will receive only verbal guidance.Both groups will be evaluated by a blind evaluator in the preoperative and postoperative periods (6 weeks and 6 months). The evaluations will be divided into five stages. Anthropometric measurements of the individual will be made and then the WOMAC functionality questionnaire and the Kinesiophobia Cover Scale will be applied.Then the individual will walk for 5 meters for three-dimensional gait analysis and electromyographic analysis of the quadriceps and femoral biceps. The evaluation of functional mobility by Timed Up And Go and assessment of postural control in an equilibrium platform will also be performed. Statistical data will be analyzed by analysis of variance 3x2 considering factor time (pre, post 6 weeks and post 6 months) and groups (with and without information leaflet). The value of p will be 0.05.
Read the detailed description
The study will be developed in the dependencies of the Laboratory of Biomechanics of the Center for Health Sciences and Sports of UDESC. In the preoperative period the subjects will be informed about their physical conditions as well as signs and symptoms of the postoperative period. One group (GI) will receive this information verbally and one leaflet while the other group (GC) will receive only verbal information. The allocation in these groups will be through a lottery, carried out by a member of the team who will not participate in the evaluation stages.
This staff member will read the booklet individually for each GI participant, in a reserved room, before handing out the leaflet to take home. GI participants will be encouraged to reread the information in the home environment and will be asked about the completion of this in the following steps by the staff member responsible for the blinding.
All participants included in the study will perform the kinematic, kinetic and electromyographic gait analysis as well as evaluation of fear of movement, functional mobility and self-perceived functionality in the pre (baseline)-and postoperative period (6 weeks and after 6 months).
The total duration of each evaluation will be approximately 2 (two) hours and 30 (thirty) minutes and all collections will be carried out by the same team. The participant will be allowed to stop the test if they feel pain or become fatigued.

What is being measured
The primary outcome is the main question the study is designed to answer.
Timed up And Go Test score
The timed up and go requires a patient to rise from a chair walk three meters around a piece of tape and return to the chair again as quickly as possible. The TUG has good inter-rater and intra-rater reliability and validity for functional testing in older adults at risk for falls. The test is easy to administer and can be completed in two to three minutes.Change from baseline (pre-operative) in the functional mobility. The variable will be measured in seconds.
Measured: pre-operative; 6 weeks; 6 months
Secondary outcomes (3)
EMG activity
Electromyographic activity of rectus femoris, vastus lateralis, vastus medialis, vastus medial and gastrocnemius by NORAXON WIRELESS EMG. Change from baseline (pre-operative).The variable will be measured in % of maximal voluntary contraction.
Measured: pre-operative; 6 weeks; 6 months
Kinematics
Gait analysis by VICON three-dimensional ,10-camera motion capture system.The outcome measurement is assessed at pre-operation, six weeks and six month after operation. Change from baseline (pre-operative). The variable will be measured in degrees.
Measured: pre-operative; 6 weeks; 6 months
Kinetics
Gait analysis by AMTI plate force. The outcome measurement is assessed at pre-operation, six weeks and six month after operation. Change from baseline (pre-operative). The variable will be measured in newtons
Measured: pre-operative; 6 weeks; 6 months

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 18 Apr 2019.
