About this study
Official title: Effects of Laser Therapy on Chronic Knee Joint Osteoarthritis Patients
Knee osteoarthritis is the most common condition presented in physiotherapy OPD.LASER therapy is new treatment option and to find out its effects in knee osteoarthritis is need of the hour. With this research one can find out best treatment program for knee osteoarthritis patients which can be shared with other community members. If there will be added effect of LASER treatment in reducing the visits or stays it will be a cost effective option. this study will help to find better management option for patients with knee osteoarthritis.
This study will address the scarcity of research on this topic in Pakistan and will help to raise awareness among patients about the effects of LASER THERAY.
Read the detailed description
Osteoarthritis (OA) is a degenerative joint disease characterized by the loss of articular cartilage, subchondral bone remodeling, joint space narrowing and the formation of bone spurs. The initiation of cartilage breakdown is stimulated by mechanical stress or injury and the degenerative process progresses slowly over many years. In the advanced stage of OA, the abnormal remodeling of cartilage and subchondral bone results in the formation of osteophytes at the joint surface and margins, which irreversibly destroys the affected joint. Obesity, previous trauma, female gender and older age are considered the most common risk factors for knee OA. The prevalence of radiographic KOA for all age groups and found a value of 27.3 % for women and 21.0 % for men.Clinical manifestations include joint pain, stiffness, decreased range of motion (ROM), muscle weakness, proprioceptive changes, difficulties in activities of daily living (ADL) such as walking, climbing / descending stairs and housekeeping[5]Many physical therapy agents such as ultrasound[6], electrical stimulation, strengthening exercise[8]and thermal therapy[9] have been introduced.
Because of the non-invasiveness and advantage of inciting nearly no adverse side effects, low-level laser therapy (LLLT) has been widely used to relieve pain in different musculoskeletal disorder. It also promotes fibroblasts, collagen synthesis, cell oxygen recovery, and bone remodeling. Laser efficacy depends on 4 factors of wavelength, duration of treatment, dose, and areas of the application.Low level laser therapy induces photochemical physiological actions in living tissues at the cellular level. Some of these effects include cellular oxygenation, release of neurotransmitters associated with pain modulation and release of anti-inflammatory, endogenous mediators. LLLT consists of a monochromatic light source without any thermal effect that stimulates reparative properties in human cartilage. Moreover, it has an analgesic effect, although the mechanisms through which this occurs remain uncertain. The suggested mechanisms include: increased mitochondrial ATP and tissue oxygenation, increased levels of neurotransmitters implicated in pain modulation (such as serotonin) and anti-inflammatory effects. Study stated that the reduction in pain through using LLLT might be due to mechanisms such as physiological effects mediated by photochemical actions at cellular level in animal or human tissue, and through increased levels of the neurotransmitters implicated in pain modulation, such as serotonin. Some researchers have also concluded that LLLT has an effect on joint cartilage regeneration, achieved through proliferation of chondrocytes and synthesis and secretion of extracellular matrix.
A study on "Effect of laser therapy on chronic osteoarthritis of the knee in older subjects" showed that there was a significant reduction in VAS and pain intensity, an increase in isometric muscle strength and range of motion of the knee as well as increase in physical functional ability in three treatment groups.
A study on "Efficacy of low-level laser therapy on pain and disability in knee osteoarthritis: systematic review and meta-analysis of randomized placebo-controlled trials" showed that LLLT reduces pain and disability in KOA at 4-8 J with 785-860 nm wavelength and at 1-3 J with 904 nm wavelength per treatment spot.
A study on "effectiveness of low-level laser therapy in patients with knee osteoarthritis: a systematic review and meta-analysis" this study indicated that low level laser therapy has neither early nor later benefits in reducing pain or improving function in patients with KOA.
A study on "The Effect of Low Level Laser Therapy on Pain and Range of Motion of Patients With Knee Osteoarthritis" showed that the effectiveness of low-power laser in reducing pain and improving the range of motion in patients with knee osteoarthritis is similar to the effectiveness of the placebo laser. Low-power laser is recognized as an appropriate medical modality to treat knee osteoarthritis in animals and humans and can be used along with acupuncture or exercise.
A study on Effect of low level laser therapy (904nm) and static stretching in patients with knee osteoarthritis: a protocol of randomized controlled trial showed that the The European League Against Rheumatism (EULAR) recommendations indicate stretching exercises as an adjunctive treatment.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Group A (ExperimentalOther
Laser therapy is performed on patients in supine lying position. Treatments will be delivered with a diode laser (wavelength 830 nm, continuous wave, power 50 mW) in skin contact at a dose of 6 J/point. Treatment times per point are in the range of 30 seconds to 1 minute. eight points were irradiated per session.
Conventional therapy will include:
- TENS for 15 minutes
- Hot pack for 15 minutes
- Hamstrings muscle stretching and calf muscle stretching. Strengthening exercises ,straight leg raising exercise in crook lying position
- Joint mobilizations
Group B (Control)Diagnostic test
- Participants of this group will receive only conventional therapy which will include;
- TENS for 15 minutes
- Hot pack for 15 minutes
- Hamstrings muscle stretching and calf muscle stretching.Each stretch was sustained for 30 seconds, with 10-second rest intervals.
- Strengthening exercises include quadricep drills(full knee extension maintained for 5 seconds, followed by a 5-second rest) 20 repetitions per session,straight leg raising exercise in crook lying position(the patients were asked to tense the quadriceps muscle, elevate the limb to 45° and maintain it for 6 seconds, and lower the limb slowly and then relax for 6 seconds; the exercise was performed for three sets of 10 repetitions per session).
- Joint mobilizations (tibiofemoral extension and flexion; patellofemoral medial-lateral and inferior glide).

Questions about this trial
What is this clinical trial studying?
A study testing Group A (Experimental in people with Knee Osteoarthritis, run by Riphah International University at 1 site in Pakistan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 6 May 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Pakistan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
