Effectiveness of Manual Therapy and Neuromuscular Training in the Management of Knee Osteoarthritis

University of Tabuk60 enrolled

Overview

The purpose of the study is to compare the short-term effectiveness of manual therapy with neuromuscular training and conventional physical therapy with neuromuscular training in patients with knee osteoarthritis.

Knee osteoarthritis (OA) is a major public health problem, characterized by progressive degeneration and loss of articular cartilage, resulting in pain, limitation of movement, imbalance, functional disability, and diminished patient quality of life. Regular participation in physical activity has been recognized for several years as being beneficial in the management of knee OA. The role and effectiveness of manual therapy techniques and conventional physical therapy are evident from the existing literature, but no comparison was found for the combination of neuromuscular training (NMT) in patients with knee OA. Thus, the aim of this study is to compare the short-term effectiveness of manual therapy (MT) versus conventional physical therapy (CPT) with NMT in the management of knee OA after six weeks of treatment.

Interventions

Manual therapy techniquesOTHER

Passive joint mobilization techniques are applied to the affected knee joint. For the first week (three sessions), the joint mobilization exercises included grade I or II rhythmic oscillations. During the following weeks, grade III or IV oscillation techniques were applied, depending on the level of tolerance and pain of each patient. In knee distraction, the patients are in a prone position with 50° knee flexion, and the physical therapist applies the techniques. The dorsal and ventral glides was performed with the patient in a supine position.

Transcutaneous Electrical Nerve Stimulation (TENS)DEVICE

Transcutaneous electrical nerve stimulation (TENS) therapy treats pain using low-voltage electric currents. A small device administers the electrical current to or near nerves. TENS treatment inhibits or changes pain perception.

Outcomes

Primary Outcomes

Numeric Pain Rating Scale

The average pain intensity over the last week at the time of testing was measured on a numerical pain rating scale, where 0 represented no pain and 10 represented the worst pain possible.

Time frame: 6 weeks

Goniometric measurement for ROM

To check the range of motion (ROM) of the knee joint, the joint will be extended as far as it can go while the person is lying on their back three times. The angle at the maximum flexion position was measured with a goniometer, and the average angle was recorded.

Time frame: 6 weeks

Western Ontario and Mc Master Osteoarthritis Index (WOMAC)

It is a questionnaire for the evaluation of treatment results in patients with lower extremity osteoarthritis, and it divides difficulties in daily living into scales. WOMAC scores are recorded on a five-point Likert scale of 0-4, where 0 = no pain or limitation, 1 = mild pain or limitation, 2 = moderate pain or limitation, 3 = severe pain or limitation, and 4 = extreme pain or limitation. Maximum scores for pain, stiffness and physical functions were 20, 8, and 68, respectively, with total scores of 96 indicating greater disease severities.

Time frame: 6 weeks

Short-Form Health Survey (SF-36)

This instrument consists of 36 items, grouped into eight domains: functional capacity, physical aspects, pain, general health, vitality, social aspects, emotional aspects, and mental health. A measurement scale with values ranging from 0 (the worst health status) to 100 (the best health status) was used to give each subject and each of the eight dimensions a score.

Time frame: 6 weeks

Single-leg stance time test

This test has been used to assess static standing balance in individuals with knee OA. The single-leg stance test was measured by recording the time in seconds (30s maximum) while participants are asked to balance on one leg while keeping their hands on their hips. The test starts when the free foot lifts off the ground and is stopped if: (1) the swing limb touches the ground; (2) the stance foot moves on the floor; (3) the swing foot touches the tested limb; or (4) the hands move away from the hips.
