Outcome Measures

Primary Outcomes (1)

  • Muscle strength

    The muscle strength of the participants will be evaluated with a hand dynamometer. Before the measurements, participants will be placed in a sitting position on the bed with hips and knees flexed at 90º, feet free, arms crossed over the chest and without support. For the test, the participant will be asked to do maximum knee extension and at the last point, resistance will be given to disrupt the position with a hand dynamometer. When the test position is disrupted, the score seen on the dynamometer screen will be recorded.

    8 weeks

Secondary Outcomes (8)

  • Joint position sense

  • Muscle structure and knee joint cartilage thickness

Study Arms (3)

conventional physiotherapy

ACTIVE COMPARATOR

Demographic and medical information of the patients (age, gender, height and body weight, occupation, educational status, CV, family history and surgical history, medical history related to knee osteoarthritis) and pain level will be questioned. Conventional physiotherapy modalities will be applied in the group; exercise training, hotpack, ultrasound and transcutaneous electrical nerve stimulation (TENS). Patients will be treated for one hour, three days a week, for eight weeks. The physical functions, muscle structure and knee joint cartilage thickness, quality of life and functional status of the patients will be evaluated before and after treatment.

Other: conventional physiotherapy

NMES

ACTIVE COMPARATOR

Demographic and medical information of the patients (age, gender, height and body weight, occupation, educational status, CV, family history and surgical history, medical history related to knee osteoarthritis) and pain level will be questioned. In addition to conventional physiotherapy methods, passive NMES treatment will be applied in the group.Patients will be treated for one hour, three days a week, for eight weeks. The physical functions, muscle structure and knee joint cartilage thickness, quality of life and functional status of the patients will be evaluated before and after treatment.

Interventions

Conventional physiotherapy is a treatment method that includes exercise training, hotpack, ultrasound and TENS (electrotherapy) applications.

NMESconventional physiotherapysuperimposed NMES
NMESOTHER

Neuromuscular Electrical Stimulation (NMES) is a non-invasive method that activates intramuscular nerve branches and produces visible contractions through surface electrodes placed on skeletal muscles.

NMES

Superimposed NMES technique is the use of NMES with voluntary muscle contraction.
