Efficacy of laser acupuncture for carpal tunnel syndrome: A study protocol for a prospective double-blind randomized controlled trial

Effects of the invasive and non-invasive systemic photobiomodulation using low-level laser in experimental models: A systematic review

Systemic photobiomodulation (PBM) of the blood or over blood vessels has been associated with bio-stimulating, vasodilating, and anti-inflammatory properties. This treatment modality has been used for modulating inflammatory processes, tissue repair, atherosclerosis, and systemic arterial hypertension, and is described more often in clinical studies than experimental models. Therefore, the aim of the present study was to conduct a literature review regarding the effect of systemic PBM involving the intravascular laser irradiation of blood (ILIB) or non-invasive vascular photobiomodulation (VPBM) using low-level laser (LLL) in experimental (animal) models. The PubMed/MEDLINE®, Scopus, SPIE Digital Library, and Web of Science databases were searched for articles on the use of VPBM with LLL in animal models. Nine original articles met the inclusion criteria and were critically evaluated. The variables of interest were the dosimetric laser parameters, different methods for delivering energy, and the main results. The use laser in the red spectrum was more prevalent and VPBM (non-invasive) predominated over ILIB (invasive). No standardization was found in the dosimetric parameters. However, the studies showed the positive effects of VPBM on arterial pressure and blood circulation, the positive effects of ILIB on blood composition and hematological markers, as well as positive effects of both forms of systemic PBM (ILIB and VPBM) on the tissue repair process. In conclusion, the studies evaluated in the present review showed that the use of systemic PBM with ILIB or non-invasive VPBM induced positive effects, modulating metabolic conditions and tissue repair. However, there is a need for standardization in the dosimetric parameters for the different conditions and processes evaluated using experimental models.

The Novel Digital Therapeutics Sensor and Algorithm for Pressure Ulcer Care Based on Tissue Impedance

Visual diagnosis and rejuvenation are methods currently used to diagnose and treat pressure ulcers, respectively. However, the treatment process is difficult. We developed a biophotonic sensor to diagnose pressure ulcers and, subsequently, developed a pressure ulcer care device (PUCD.) We conducted animal and clinical trials to investigate the device's effectiveness. We confirmed the accuracy of the pressure ulcer diagnosis algorithm to be 91% and we observed an 85% reduction in immune cells when using the PUCD to treat pressure ulcer-induced mice. Additionally, we compared the treatment group to the pressure ulcer induction group to assess the PUCD's effectiveness in identifying immune cells through its nuclear shape. These results indicate a positive effect and suggest the use of PUCD as a recovery method for pressure ulcer diagnosis and treatment.

Laser acupuncture in the treatment of neuropathies in dentistry: a systematic review

Laser acupuncture can be used to treat neurosensory alterations and motor disorders caused by dental treatments. This study aimed to review the existing literature on the effects of laser acupuncture on neuropathies in the context of dentistry and to search for treatment modalities in which this technique is used. This systematic review was conducted in accordance with the Cochrane Collaboration guidelines and the PICOS strategy. Randomized clinical trials that evaluated laser acupuncture as a primary intervention for facial neuropathy were included. We searched the database for relevant studies and manually searched the gray literature until April 2022, and finally included four studies. The study was considered eligible if it included patients with paresthesia, facial paralysis, or neuralgia, neuropathies within dentistry, and referred to the application of laser acupuncture as a treatment method. The risk of bias was assessed using the RoB 2 tool. It was observed that the recommended wavelengths ranged from 790 nm to 810 nm, with a frequency of at least two applications per week, and to a greater or lesser degree, all evaluated studies obtained an improvement in sensory or motor recovery of the facial nerves. The use of laser acupuncture presented itself as a viable alternative in dentistry for the treatment of paresthesia and facial paralysis due to its therapeutic potential in neuropathic treatment (CRD42022344339).

Efficacy of electroacupuncture in assisting postoperative healing of distal radius fractures: study protocol for a randomized controlled trial

BACKGROUND

Manual reduction and surgical treatment are common methods for distal radius fractures (DRFs). The existing literature suggests that postoperative combined rehabilitation treatment and medication are effective for the healing of DRFs. However, the side effects of these treatments remain to be solved. Previous studies have shown that electroacupuncture (EA) can effectively relieve wrist swelling and improve the joint function in patients with DRFs, but more evidence is needed to prove the effectiveness of EA. This trial aims to explore the efficiency and feasibility of combined EA treatment in postoperative treatment of DRFs compared with routine treatment.

METHODS

This is a parallel randomized controlled trial. A total of 222 patients diagnosed with moderate DRFs will be recruited and randomly assigned to an EA group or a routine treatment group at a ratio of 1:1. Routine treatment group will receive medication and rehabilitation. Yangxi (LI 5), Yangchi (TE 4), Yanggu (SI 5), Hegu (LI 4), and Taiyuan (LU 9) will be selected in the EA group for intervention three times a week on the basis of routine treatment. Both groups will receive 8 weeks of treatment and 4 weeks of follow-up. The primary outcome will be ulnar positive variance. The secondary outcomes will include radiographic healing rate, bone strength, hemorheological indices, serum biochemical indicators and inflammatory factors, grip strength, wrist swelling score, patient-rated wrist evaluation, disabilities of arm, shoulder and hand, and visual analogue scale. Outcomes will be evaluated at baseline, postoperative 3rd day, 2nd, 4th, 6th, 8th, and 12th weeks.

DISCUSSION

The results of this study will help establish a more optimized scheme to treat patients with DRFs. Trial registration Chinese Clinical Trial Registry ChiCTR2200062857. Registered on 21 August 2022, www.chictr.org.cn/com/25/showproj.aspx?proj=175567 .

Ultrasound Acupuncture for Oxaliplatin-induced Peripheral Neuropathy in Patients With Colorectal Cancer: A Pilot Study

BACKGROUND

Oxaliplatin is frequently used in the treatment of metastatic colorectal cancer. However, peripheral neuropathy is a severe adverse effect of oxaliplatin that may persist and impact quality of life.

OBJECTIVE

To assess the potential effects of ultrasound acupuncture for the alleviation of symptoms related to oxaliplatin-induced peripheral neuropathy (OIPN) among patients with metastatic colorectal cancer.

DESIGN

Prospective cohort pilot study.

SETTING

Education and research hospital.

PARTICIPANTS

Patients with a diagnosis of stage II-IV colorectal cancer undergoing oxaliplatin-based treatment regimens who experienced OIPN symptoms (n = 17).

INTERVENTIONS

Pulsed therapeutic ultrasound (1 MHz) at bilateral acupuncture points of PC6, PC7, BL60, and KI1 was administered for 5 minutes per point daily for 12 days.

MAIN OUTCOME MEASUREMENTS

Pain Quality Assessment Scale (PQAS), Chemotherapy-induced Neurotoxicity Questionnaire (CINQ), quantitative touch-detection threshold, cold-trigger pain withdrawal latency, and quality of life (EORTC QLQ-C30) were measured at baseline (day 0), pre-intervention (day 12, post wash-out period), post-intervention (day 24), and final follow-up (day 54). A P value of less than .05 was considered statistically significant.

RESULTS

Scores of PQAS and CINQ significantly improved after ultrasound acupuncture at post-intervention and follow-up compared to both baseline and pre-intervention. Similar trends were also observed for the quantitative sensory testing, where touch-detection threshold significantly decreased and cold-trigger pain withdrawal latency significantly increased after ultrasound acupuncture. Patients also showed an improvement on quality of life outcomes as measured by QLQ-C30 post-intervention and at follow-up.

CONCLUSIONS

Ultrasound acupuncture could be an effective intervention for OIPN symptoms for patients with colorectal cancer. However, larger and randomized clinical trials with placebo controls are needed to confirm such effects.
