About

In our study, we aimed to compare the effects of functional electrical stimulation (FES) and an exercise program on quadriceps muscle strength and structural characteristics, as well as their impact on gait analysis, pain severity, and quality of life, in order to determine more effective and beneficial treatment programs for patients with knee OA.

Full description

The study is planned as a prospective trial. Seventy patients, male or female, aged 50-65, who present to Ankara Bilkent City Hospital, Physical Therapy and Rehabilitation Hospital as outpatients, are diagnosed with osteoarthritis classified as Kellgren-Lawrence radiographic stage 2-3, and agree to participate in the study will be included.

According to the research criteria, initial evaluations will be conducted, and the demographic data (such as age, gender, height, weight, date of birth, occupation, systemic diseases) of eligible patients will be recorded by Dr. Betül Küçük Gürsoy. Patients' personal information will remain confidential and will not be shared with any person or institution/organization.

At the start of treatment, the VAS pain score, WOMAC, Quality of Life (SF-36) Scale, 6-Minute Walk Test (6-MWT), and Timed Up and Go Test (TUGT) will be recorded by Dr. Betül Küçük Gürsoy. Quadriceps muscle thickness and rectus femoris cross-sectional area will be measured via ultrasonography and recorded in a blinded manner by Dr. Ayşe Merve Ata.

Concurrently, isometric muscle strength measurements of the knee flexor and extensor groups using the Diers Myoline system will be performed and recorded in a blinded manner by Physiotherapist Selin Koç. Gait analysis (cadence, step length, stride length, step width, foot angle, and walking speed) using the Zebris FDM3 device will be conducted and recorded by Dr. Betül Küçük Gürsoy.

Subsequently, patients will be divided into two groups. The first group will receive aerobic exercise (stationary cycling) 5 times a week for a total of 10 sessions, administered by Dr. Betül Küçük Gürsoy. Additionally, they will be given a 6-week home exercise program to be performed 3 times a week, consisting of knee flexor and extensor range of motion exercises and isometric strengthening. The second group will receive Functional Electrical Stimulation-Cycling (FES-Cycling) 5 times a week for a total of 10 sessions, administered by Dr. Betül Küçük Gürsoy. They will also be given the same 6-week home exercise program (3 times a week) consisting of knee range of motion and isometric strengthening exercises.
