Abstract
Reduced range of motion is one of the main symptoms of knee osteoarthritis. These deficits are believed to have a negative impact on activities of daily living. The aim of the study was to examine how manual therapy and closed-chain kinematic exercises affect the range of motion in patients with knee osteoarthritis. Sixty-six patients with knee osteoarthritis were recruited and divided into three groups: manual therapy group, exercise group, and control group. The following parameters were evaluated before and after 10 days of rehabilitation: the range of motion in the open and closed kinematic chain using Orthyo sensors, pain intensity using Visual Analogue Scale (VAS), and the subjective functional assessment in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). The results indicate an increase in the range of motion after manual therapy in the open chain test and an increase in the possible range of motion in the closed chain test in the exercise group. Both study groups showed significant improvement of WOMAC-assessed function and a significant decrease of VAS-assessed pain following rehabilitation. Manual therapy and exercise affect the range of motion in patients with knee osteoarthritis. When examining the range of motion, it is worth taking into account various biomechanical conditions.
Highlights
Osteoarthritis (OA) is a common condition reported in females more frequently than in males [1].It typically affects joints in hands, feet, spine, knees, and hips [2]
When reviewing the available study results, we have found that no research has been performed to determine the effect of specific therapeutic procedures on the range of motion and how they affect ADLs
The flexion angle was greater in the control group by 11.3 and 8.7 degrees before and after therapy, respectively, in comparison with group E, and by 13 and 8.1 degrees before and after therapy, respectively, in comparison with group Manual Therapy (MT)
Summary
Osteoarthritis (OA) is a common condition reported in females more frequently than in males [1]. It typically affects joints in hands, feet, spine, knees, and hips [2]. Primary symptoms reported by patients suffering from osteoarthritis of the knee (OAK) include pain, stiffness, decreased mobility, and muscle weakness [1,3]. It has been shown by researchers that ADLs are affected by the pain reported and by the range of motion [5]. The range of motion (ROM) may decrease due to pain, loss of elasticity in connective tissue structures, or bone abnormalities [6]
