Detailed Description
Nowadays, it is seen that the results of an increasing number of TDP surgeries increase patient satisfaction and have satisfactory results. However, TDP surgery is a serious trauma that causes pain in patients.
TENS is an easy-to-apply, inexpensive, noninvasive, noninvasive method that uses electrical current to activate nerves with therapeutic effects in the treatment of acute and chronic pain. It is also seen as a promising practice in patients undergoing total knee replacement surgery by the American Society of Regional Anesthesia and Pain Medicine (ASRA) and the European Society of Regional Anaesthesia and Pain Therapy (ESRA).
The study was planned as a randomized controlled study to examine the effect of TENS on acute pain, functionality and quality of life after TDP. The hypotheses of the study; H1a- TENS applied after TDP positively affects the level of pain in patients. H1b- TENS applied after TDP affects the improvement in functional status in patients.
H1c- TENS applied after TDP reduces the analgesia consumption of patients. H1d- TENS applied after TDP positively affects the quality of life of patients. Type of Study: Randomized controlled trial. Method: 52 patients (26 controls, 26 interventions) who underwent total knee replacement surgery will be randomized and divided into two groups as intervention and control groups. TENS will be applied to the intervention group in addition to the routine treatment and care in the clinic, on the other hand, no intervention will be made to the control group other than routine treatment and care. Data will be collected with Patient identification form, Pain Evaluation Form, Visual Analogue Scale (VAS), Analgesic Drug Tracking Form, Joint Range of Motion (ROM) Follow-up Form, Western Ontario and McMaster Universities Arthritis Index (WOMAC), Quality of Life Scale (SF-36).
While evaluating the data, it is planned to be analyzed as randomized.It is planned to use multiple completion methods when there are missing data.Statistical analyzes are planned to be evaluated with the SPSS-24 package program. It is planned to use frequency charts and descriptive statistics in order to interpret the data, parametric techniques for normal distributions and non-parametric techniques for non-normal distributions.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
No Intervention: Control group
When the patients are admitted to the clinic, the patient identification form and the SF-36 Quality of Life Scale will be filled by face-to-face interview method.
On the morning of the operation, before the operation, the GCS, EHA and WOMAC index will be filled.
After the operation, the pain during rest and movement (24., 48., 72., 96.
hours and 15. days) will be evaluated with VAS.
The total amount of analgesics used by the patients will be recorded by looking at the nurse observation form records where the nurses recorded the drugs they administered at the 24th, 48th, 72nd, and 96th hours after the surgery, and by asking the patients on the 15th day after discharge.
The WOMAC Index will be re-administered at discharge and on the 15th day, and the VCS, ROM, and the SF-36 Quality of Life Scale on the 15th day.

|
Experimental: Intervention group
Unlike the control group, the patients in the intervention group will be informed about TENS and the application will be made.
The electrodes of TENS will be placed 2 cm below and 2 cm above the incision site.
TENS settings Frequency: 100 Hz; Pulse width (duration): 150 μs; Flow Intensity (Amplitude): By adjusting it to be 30 mA, TENS will be applied 3 times a day (09.00,
13.00, 17.00) for 20 minutes during the time the patients stay in the clinic (3 days).It is planned to start the TENS application the day after the surgery.
|
Conventional (traditional) TENS will be applied to the patients.
The frequency will be 100 Hz, the pulse width (time) will be 150 μs, the current intensity (amplitude) will be 30 mA.
In addition to routine care and treatment, TENS will be applied to intervention group patients.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Visual Analogue Scale (VAS) Change
Time Frame: 1st day of admission to the clinic change VAS score at before intervention, 24th postoperative hour change from baseline VAS score before the intervention, postoperative 48th, 72th and 96th hours,15th day change from baseline VAS score after intervention
|
The Visual Analogue Scale (VAS) is a scale where the pain is evaluated between 0-10 (0; no pain, 10; unbearable pain) on a ruler that can be used horizontally or vertically, on which the patient can mark his or her own pain.The length of the distance from the point where there is no pain to the point marked by the patient is measured in centimeters and the numerical value found shows the severity of the patient's pain.
It is used in various populations, including patients with total knee replacement, to evaluate both the severity of pain and the effectiveness of treatment/intervention on pain.
|
1st day of admission to the clinic change VAS score at before intervention, 24th postoperative hour change from baseline VAS score before the intervention, postoperative 48th, 72th and 96th hours,15th day change from baseline VAS score after intervention
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Western Ontario and McMaster Universities Arthritis Index (WOMAC) Change
Time Frame: 1st day of admission to the clinic change WOMAC score at before intervention, change from baseline the WOMAC score at 4th postoperative day, 15th postoperative day change from baseline WOMAC score
|
WOMAC is planned to be used to assess functionality in patients.The score to be taken from the scale is between 0-100. An increase in score indicates deterioration in physical function. The WOMAC index is a valid and reliable index that is widely used for the evaluation of patients with osteoarthritis. The index consists of three parts and 24 questions in which pain, stiffness and physical function are questioned. Each question was scored according to the Likert scale as 0=absent, 1=mild, 2=moderate, 3=severe, 4=very severe. The score of each section is calculated in itself and the total score varies between 0 and 100. High scores indicate an increase in pain and stiffness, and deterioration in physical function. |
1st day of admission to the clinic change WOMAC score at before intervention, change from baseline the WOMAC score at 4th postoperative day, 15th postoperative day change from baseline WOMAC score
|
The Quality of Life Scale (SF-36) Change
Time Frame: 1st day of admission to the clinic change quality of life score at before intervention, 15th postoperative day change from baseline quality of life score
|
The Quality of Life Scale (SF-36), one of the most used scales to measure quality of life; It is a self-assessment scale that can be filled in a short time and is highly sensitive.While applying the scale, individuals are asked to answer considering the last 4 weeks.
The scale consists of 36 questions and 8 sub-parameters (body pain, limitation due to physical problems, limitation due to mental problems, mental well-being, fatigue, general health perception, social function and physical function).
In scoring, each parameter is evaluated between 0 and 100 points.
A score of 0 indicates poor health, and a score of 100 indicates good health.
The higher the score, the higher the quality of life.
