Knee Osteoarthritis
Conditions
Brief summary
Background: Osteoarthritis is a common cause of chronic pain and disability in elderly people. Objective: To evaluate the efficacy of low-level laser therapy (LLLT) in combination with Maitland mobilization and conventional physical therapy in patients with chronic knee osteoarthritis. Design: Pre-test post-test randomized control trial.
Detailed description
Knee OA is associated with pain and disability, high treatment costs, decreased productivity, and absence from work and thus has a substantial and growing burden on society Objective: To evaluate the efficacy of low-level laser therapy (LLLT) in combination with Maitland mobilization and conventional physical therapy in patients with chronic knee osteoarthritis. Participants: Seventy five subjects of both genders with age range from 50 to 65 years, with proven bilateral knee OA diagnosed and referred by orthopaedist were recruited for the study and randomly assigned into three groups.
Interventions
DEVICELow Level laser therapy
is a non-invasive light source treatment that generates a single wavelength of light. It emits no heat, sound, or vibration. It is also called photobiology or bio-stimulation
is a process of examination; assessment and treatment of musculoskeletal disorders by manipulative physiotherapy where a chain of oscillatory joint mobilization grades based on the pathological limit of tissue are used

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Visual analogue scale | Four weeks | Is a bidirectional 10 cm straight line with two labels, that is, no pain and worst possible pain, located at either end of the line. Patients were instructed to draw a vertical mark on the line indicating their pain level where zero mean no pain and 10 means worst imaginable pain |
| Pressure Algometer | Four weeks | is a handheld pressure algometer that responds linearly to force application between 0 and 5 Kg and it has a 1-cm2 round rubber tip. |
| Knee digital goniometry | Four weeks | Baseline digital absolute + axis TM goniometer was used which consisted of one movable arm and one fixed arm and fulcrum |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Knee injury and osteoarthritis outcome score short form | Four weeks | consists of a seven items measure of physical function descended from the items of the function, daily living and function, sports and recreational activity subscales of the KOOS Item responses are coded from 0 to 4, none to extreme respectively. The questionnaire is scored by summing the raw response (range 0-28) and then using the nomogram so the raw score is converted to a true interval score (0-100) where zero means no difficulty and 100 means extreme difficulty |
