“…Acupuncture practitioners have combined the characteristics of LA with traditional Chinese medicine (TCM) theory and acupuncture intervention principles in treating diseases for several years with good responses. There have been more publications on the application and efficacy of LA, including for the problems in which traditional acupuncture is difficult or only limited in intervention, which improves the functional outcomes after total knee replacement [3], carpal tunnel syndrome (CTS) symptoms [4], long-term unrecovered facial palsy [5], pain reducing and increasing motion in temporomandibular disorders patients [6], spasticity relieve of cerebral paralysis children [7], and speech and social interaction performance in autism children [8]. In other words, the physiological mechanisms of LA and LLLT are likely to be the same or similar to some extent.…”

Laser acupuncture (LA) has been more applicated in the clinical practice with good responses, but the dosage and parameter settings are still inconsistent with the arguments. This study is focused on the effect of LA on heart rate variability (HRV) with different energy density (ED). Based on the Arndt–Schulz law, we hypothesized that the effective range should fall within 0.01 to 10 J/cm2 of ED, and settings above 10 J/cm2 would perform opposite or inhibitory results. We recruited healthy adults in both sexes as subjects and choose bilateral PC6 (Neiguan) as the intervention points to observe the HRV indexes changes by an external wrist autonomic nerve system (ANS) watch on the left forearm. The data from the ANS watch, including heart rate, blood pressure, and ANS activity indexes, such as low frequency (LF), high frequency (HF), LF%, HF%, LF/HF ratio, and so on, were analyzed by the one-way ANOVA method to test the possible effect. In this study, every subject received all three different EDs of LA in a randomized order. After analyzing the data of 20 subjects, the index of HF% was upward and LF/HF ratio was downward when the ED was 7.96 J/cm2. Otherwise, the strongest ED 23.87 J/cm2 performed the opposite reaction. Appropriately, LA intervention could affect the ANS activities, with the tendency to increase the ratio of parasympathetic and decrease the ratio of sympathetic nerve system activities with statistically significant results, and different ED interventions are consistent with Arndt–Schulz law with opposite performance below and above 10 J/cm2.

“…From the review and analysis of the results we concluded that laser and therapeutic ultrasound are important physiotherapy methods to combat impairments such as CTS. Based on the clinical trials that evaluated the effect of the laser, we observed that three out of five [10,11,13] clinical trials found that there is a reduction in symptoms, while in two of them [12,14] the laser had no beneficial properties. According to these studies, the laser should be applied 3-5 times a week for 4-6 weeks.…”

Carpal tunnel syndrome (CTS) is a peripheral neuropathy characterized by pain, numbness, and paresthesia. These symptoms usually occur on the thumb, index, middle and ring fingers. The syndrome is caused by compression of the median nerve as it crosses the wrist through the carpal tunnel. Physiotherapy is able to help patients with CTS in many cases. In recent years, the use of laser and therapeutic ultrasound has become increasingly popular in the treatment of CTS. The aim of this study is to review the latest research data and evaluate the effect of laser and therapeutic ultrasound, but also to compare the treatment methods with each other to find which of the two is more useful. Literature search was performed on the PubMed, PEDro (Physiotherapy Evidence Database) and Google Scholar databases. The keywords used are: carpal tunnel syndrome, laser, Ultrasound. Furthermore, appropriate criteria were applied in the search, such as language and time restriction. This review included 10 clinical studies. The literature review led to the conclusion that the application of laser and therapeutic ultrasound helps to treat the symptoms of the syndrome to a great extent. With proper application the results they offer can remain for many weeks after the end of treatment. Between the two, therapeutic ultrasound seems to be the best method of treatment, however, more studies are needed to draw a safe conclusion.

“…Studies using 780-860nm laser and energy intensity of 9-11J/cm 2 or 10.8J had better results in reducing pain, severity of symptoms and improving function and grip strength at the end of treatment in the short term. As far as other laser therapies are concerned, Juan et al [17] conducted a single blind controlled trial in 84 patients with idiopathic, mild to moderate CTS in order to observe the efficacy of Laser Acupuncture (LA) treatment. The intervention group consisted of 43 patients and was compared with placebo LA treatment (41 participants).…”

The carpal tunnel syndrome (CTS) is a common type of peripheral entrapment of the median nerve that occurs in the wrist and specifically in the carpal tunnel. Laser therapy is one of the most widely used therapies available to the physiotherapist for the treatment of symptoms in the management of patients with CTS. However, its exact effects as well as the appropriate treatment parameters have not been fully elucidated. The aim of this review is to describe recent research data on the efficacy of the application of laser in improving symptoms in patients with CTS as well as to provide data on device configurations and treatment time. The following databases were searched: PEDro, PubMed and Google Scholar, with the following keywords: carpal tunnel syndrome, physiotherapy, Low-Power Laser Therapy, High-Power Laser Therapy, rehabilitation. Both clinical studies and systematic reviews were included in the review and in total 10 articles were included. The results of this review show that laser treatment seems to have a positive effect on the treatment of symptoms in patients with CTS. However, the treatment parameters need to be further investigated, as different results can be obtained with different parameters.
