Osteoarthritis of Knee

Brief summary

The goal of this clinical trial is to compare the effects of electrical dry needling versus glucosamine sulfate iontophoresis on pain intensity level, functional ability, and knee range of motion in chronic unilateral knee osteoarthritis patients.

Detailed description

Knee Osteoarthritis (OA) is a chronic disease affecting 240 million people worldwide, with a higher prevalence in older adults. The disease leads to knee deformity, laxity, and ligament instability. Dry needling, a new treatment modality, uses needle electrodes to deliver an electric current to the pain-generating trigger point, improving the physiological effects and analgesic and anesthetic effects. Iontophoresis, a safer method of drug therapy, has shown to be more effective in pain reduction in knee osteoarthritic patients. The study aims to investigate the effect of electrical dry needling versus glucosamine sulfate iontophoresis on pain intensity level, knee function, and range of motion (ROM) in chronic knee OA patients. This approach aims to maximize drug bioavailability, optimize therapeutic efficacy, and minimize side effects.

Interventions

OTHERconventional physical therapy

including transcutaneous electrical nerve stimulation (TENS) and an exercise therapy program (stretching exercises, both hip and knee strengthening, balance, and stability exercise)

In electrical dry needling, needle electrodes are used to deliver an electric current to the taut muscle band or the pain-generating trigger point. Low-frequency currents are thought to improve the physiological effects of the therapy by using electrical stimulation to enhance certain physiological reactions and achieve a speedier analgesic and anesthetic effect than that obtained with standard dry needling.

OTHERGlucosamine sulfate iontophoresis

Galvanic current mode will be used to deliver the cream through the skin. One gram of GS will be placed on positive electrode (being positively charged using Trans-arthral electrode placement technique) for administration of Iontophoresis \[40mA-min (2mA x 20minutes)\].

Masking description

The sample will be randomly divided into three groups: A, B, and C. Group A: The control group (n=20) Group B: The study group (n=20) will receive conventional physical therapy plus electrical dry needling. Group C: The study group (n=20) will receive conventional physical therapy plus glucosamine sulfate iontophoresis.

Design outcomes

Primary

MeasureTime frameDescription
Pain intensity level measurementat baseline and after 6 weeksThe visual analog scale (VAS) is a pain rating scale .A 10-cm line that represents a continuum between the two ends of the scale-no pain on the left end (0 cm) of the scale and the worst pain on the right end of the scale (10 cm)
Functional ability measurementat baseline and after 6 weeksKnee Injury and Osteoarthritis Outcome (KOOS) Score.A 0-100 scale, with zero express extreme knee problems and 100 for no knee problems, as common in orthopedic scales.
Knee ROM measurementat baseline and after 6 weeksA digital goniometer will be used to measure active knee ROM. The subject will be supine, flexing and extending their knee to the maximum. Bony landmarks will be identified for standardization and repeatability. The goniometer will be positioned over the lateral epicondyle of the femur, with the greater trochanter for reference. Measurements will be made three times, and the average value will be analyzed. Knee ROM measurements in patients with knee OA show high reliability.
