Digital Biomarkers for Neuromuscular Disorders: A Systematic Scoping Review.

Biomarkers play a vital role in clinical care. They enable early diagnosis and treatment by identifying a patient's condition and disease course and act as an outcome measure that accurately evaluates the efficacy of a new treatment or drug. Due to the rapid development of digital technologies, digital biomarkers are expected to grow tremendously. In the era of change, this scoping review was conducted to see which digital biomarkers are progressing in neuromuscular disorders, a diverse and broad-range disease group among the neurological diseases, to discover available evidence for their feasibility and reliability. Thus, a total of 10 studies were examined: 9 observational studies and 1 animal study. Of the observational studies, studies were conducted with amyotrophic lateral sclerosis (ALS), Duchenne muscular dystrophy (DMD), and spinal muscular atrophy (SMA) patients. Non-peer reviewed poster presentations were not considered, as the articles may lead to erroneous results. The only animal study included in the present review investigated the mice model of ALS for detecting rest disturbances using a non-invasive digital biomarker.

Evaluation of the efficacy and safety of herbal medicine for treating work-related chronic low back pain: A study protocol for a multicenter, randomized, controlled, clinical trial.

INTRODUCTION: In Korea, low back pain (LBP) which is occupation-related symptom is one of the major health issues owing to rapid industrialization. Even traditional Korean medicine has the long history in pain treatment, there still has been lack of supporting evidence on herbal prescription itself. Sogyeonghwalhyeol-tang, a Korean herbal medicine prescription, has been suggested as a medication for treating chronic LBP as well as work-related pains. OBJECTIVE: This study aims to evaluate the clinical efficacy and safety of herbal medicine, Sogyeonghwalhyeol-tang on work-related chronic LBP patients. METHOD: This trial is designed as a multicenter, randomized, controlled, clinical trial. Seventy-two participants who have chief complaint of LBP in Korean medicine rehabilitation center will be randomly assigned to ether Sogyeonghwalhyeol-tang group or placebo group with a ratio of 1:1. They will receive assigned drugs in 4 weeks and follow-up for 2 weeks. DISCUSSION: The result of this study will provide the valuable information for efficacy and safety of Sogyeonghwalhyeol-tang for patients with work-related chronic LBP.

Therapeutic effects of Chiljehyangbuhwan on primary dysmenorrhea: a randomized, double blind, placebo-controlled study.

OBJECTIVE: This clinical study was conducted to investigate the efficacy and safety of an oriental herbal medicine native to Korea, Chiljehyangbuhwan, in treating primary dysmenorrhea. DESIGN AND SETTING: A total of 100 primary dysmenorrhea patients who visited Kyung Hee University Korean Oriental Medicine Hospital between July 19 2004 and August 27 2004 were recruited. Secondary or drug-related dysmenorrhea was screened out through interviews and examination. The patients were grouped by fixed blocked randomization and administered either Chiljehyangbuhwan or placebo for one menstrual period in a double blind model. Visual Analogue Scale (VAS), Verbal Rating Scale (VRS), and Multidimensional Verbal Rating Scale (MVRS) were used to evaluate dysmenorrhea severity. A total of 71 patients who passed the screening test and remained to the last were divided into either placebo or Chiljehyangbuhwan group, and each were further split into smaller subsets (indication, non-indication, and unspecified group) according to Korean Oriental medical diagnosis. RESULTS: In the non-indication group, the placebo and Chiljehyangbuhwan group did not show significant difference in VAS, VRS, and MVRS scores before medication (1st VAS, 1st VRS, 1st MVRS), after medication (2nd VAS, 2nd VRS, 2nd MVRS), and in changes in scores before and after (DeltaVAS, DeltaVRS, DeltaMVRS). In the indication group, the placebo and Chiljehyangbuhwan group showed significant difference in change in VAS and MVRS scores (DeltaVAS and DeltaMVRS). No evidence of toxicity could be found, and no serious adverse reactions to Chiljehyangbuhwan were reported. CONCLUSION: The results suggest that Chiljehyangbuhwan is effective and safe in treating primary dysmenorrhea when prescribed appropriately under Korean Oriental medical diagnosis.
