Overview

This study aimed to determine the effects of different manual mobilization techniques on pain, muscle strength, and functional limitations in individuals with knee osteoarthritis (Knee OA). A double-blinded pretest-posttest experimental study. This research employed a two-arm parallel group randomized comparative design. A total of thirty participants diagnosed with knee osteoarthritis were randomly assigned and equally divided into groups 1 and 2, each containing 15 participants. Both Group 1 and Group 2 underwent Maitland and Mulligan mobilization techniques, alongside a common Interferential therapy (IFT) regimen, over the course of three sessions per week for a duration of four weeks. The assessment of pain and functional disability outcomes was conducted through the application of The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores at the baseline and four weeks following the intervention. To determine the effects of the intervention within and between the groups, the outcome scores were subjected to analysis using both dependent and independent t-tests.

Knee osteoarthritis (OA) is a prevalent disorder with significant global health implications, its prevalence varying across populations due to intricate factors. Recent investigations highlight an age-related increase in knee OA prevalence, particularly impacting those aged 60 and above, with projections indicating heightened impact due to aging demographics. Recent pathogenesis studies illuminate the intricate molecular and cellular processes underlying knee osteoarthritis (OA), encompassing cartilage degradation, subchondral bone changes, and inflammation.Recent advancements have expanded knee osteoarthritis (OA) management, including medical, surgical, and physiotherapy interventions. Pharmacological treatments such as analgesics, non-steroidal anti-inflammatory drugs (NSAIDs), and disease-modifying osteoarthritis drugs (DMOADs) remain fundamental for pain alleviation and inflammation reduction. Intra-articular therapies like corticosteroid injections and hyaluronic acid supplements offer localized relief and potential disease-modifying effects.Surgical interventions like total knee arthroplasty (TKA) provide pain relief and improved function for end-stage OA. Minimally invasive techniques like partial knee replacements and patient-specific implants aim to preserve joint function and enhance outcomes. Physiotherapy and rehabilitation are crucial, in improving stability, muscle strength, and mobility. Studies highlight tailored exercises, neuromuscular training, and proprioceptive exercises in managing OA symptoms. The integration of these approaches underscores comprehensive knee OA management, addressing pain, function, and quality of life. The outcomes of this study could offer evidence-based recommendations for clinicians, aiding them in selecting the most appropriate manual therapy approach to alleviate pain, enhance joint mobility, and improve functional capacity in knee OA patients. Ultimately, this research seeks to contribute to the optimization of knee OA management strategies, improving the well-being of those affected.

Interventions

Maitland's mobilization techniqueOTHER

Maitland's mobilization technique was performed on the patients with its all components, such as 1. Distraction 2. Anteroposterior glides 3. Posteroanterior glides 4. Medial glides and 5. Lateral glides.

Mulligan's mobilization techniquesOTHER

Mulligan's mobilization technique was performed on the patients with its all components using a therapeutic belt, such as 1. Medial mobilization with movement (MWM) for Knee flexion 2. Medial mobilization with movement (MWM) for Knee extension 3. Lateral mobilization with movement (MWM) for Knee flexion 4. Lateral mobilization with movement (MWM) for Knee extension.

Interferential Therapy (IFT)OTHER

Interferential Therapy was performed on the patients with the following parameters: career frequency 4000Hz; waveform: rectangular; sweep time: 1 second rise and fall and 5 second stay; Treatment duration: 10 minutes; sweep frequency: 10 to 130 Hz. The current intensity was adjusted until the subject reported feeling a strong tingling sensation without causing muscle contraction. A aquatic gel was applied before straping the electopads over treatment area for smooth electrical conduction.

Outcomes

Primary Outcomes

Functional limitations

Functional limitations was assessed using the Western Ontario and McMaster Universities (WOMAC) index. It includes five questions about pain, two about stiffness, and 17 on degree of disability of activities of daily living. The test questions are scored on a scale of 0-4, which correspond to: None (0), Mild (1), Moderate (2), Severe (3), and Extreme (4). The scores for each subscale are summed up, with a possible score range of 0-20 for Pain, 0-8 for Stiffness, and 0-68 for Physical Function.
