Effect of combined laser acupuncture on knee osteoarthritis: a pilot study

Lasers in Medical Science

Abstract

Our objective was to assess the efficacy and safety of combined 10.6 microm and 650 nm laser irradiation on patients with knee osteoarthritis (OA). Forty patients with OA were randomly allocated to an active laser group or to a placebo laser group (20 per group). They either received active or sham laser treatment at acupoint Dubi (ST 35) in a total of 12 sessions. There was significant difference between the two groups in the Western Ontario and McMaster Universities (WOMAC) osteoarthritis index pain score change from baseline after 2 weeks of treatment (P = 0.047). The pain reduction of the active laser treatment group was 49%, whereas that of the placebo control group was only 13%. However, due to the high patient drop-out rate, the 4-week assessment could not be analyzed. Combined laser treatment seems beneficial to patients with knee OA. However, due to the small sample size and the high drop-out rate of patients in the placebo group, a large sample-size clinical trial is warranted to determine further the therapeutic efficacy of the device.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
