Objective: The objective of this study was to evaluate a program for managing myofascial pain syndrome (MPS).

Design: The study design was a randomized controlled trial.

Setting: The setting was the pain clinic of an academic hospital in Taiwan.

Participants: Sixty-two (62) patients with a 3-month or longer history of MPS who were treated at this institution from July to November 2007 were included in the study.

Interventions: The participants were randomized to an experimental group (n = 32) or a control group (n = 30). Both groups underwent trigger-point dry needling and muscle-stretch exercise regimen for passively stretching the affected muscles to their normal lengths; the experimental group then watched an 8-minute multimedia instructional video about MPS with supplemental handouts.

Main Outcome Measures: The Brief Pain Inventory-Taiwan was administered at baseline and 1 month thereafter. The effect size model was used to measure the effects of Brief Pain Inventory-Taiwan. Bootstrap estimation was used to derive 95% confidence intervals for group differences.

Results: Compared to the control group, the experimental group had significantly less interference of pain, lower intensity of present pain, and least pain (p < 0.05). Multiple regression analysis of patients with shoulder pain revealed significantly improved pain intensity and interference of pain (p < 0.05).

Conclusions: The findings emphasize the importance of including patient education programs in MPS intervention.

Vestibular dysfunction has been reported as a potential cause in adolescent idiopathic scoliosis (AIS). However, it remained unclear how stochastic galvanic vestibular stimulation (GVS) affected kinetic performance of patients with AIS. This study aimed to investigate the effect of stochastic GVS on ground reaction forces (GRF) measures during obstacle negotiation among patients with AIS.

Background: The Montreal classification has been widely used in Crohn's disease since 2005 to categorize patients by the age of onset (A), disease location (L), behavior (B), and upper gastrointestinal tract and perianal involvement. With evolving management paradigms in Crohn's disease, we aimed to assess the performance of gastroenterologists in applying the Montreal classification.

Methods: An online survey was conducted among participants at an international educational conference on inflammatory bowel diseases.

Background: The Needs Assessment Framework (NAF) stimulates awareness of care staff to consider perspectives of clients with intellectual disabilities in decisions on involuntary care. We explored the effect of implementers' participation in a Virtual Community-of-Practice (VCoP) for designing implementation plans, on NAF implementation and staff awareness.

Method: A quasi-experimental design was used to compare implementation and awareness by care staff (n = 54) between organisations that implemented NAF with VCoP participation (N = 4) and organisations that implemented NAF as usual (N = 3).

Despite significant progress in understanding the factors influencing cognitive function in Parkinson's disease (PD), there is a notable gap in data representation for the Latinx population. This study aims to evaluate the contributors to and disparities in cognitive performance among Latinx patients with PD. A retrospective analysis was conducted based on cross-sectional data encompassing demographic, environmental, motor, and non-motor disease characteristics from the Latin American Research Consortium on the Genetics of PD (LARGE-PD) and the Parkinson's Progression Markers Initiative (PPMI) cohorts.

Background And Aims: Military veterans demonstrate high rates of heavy drinking and insomnia, but few if any studies have tested real-world, daily associations between sleep and alcohol use within this population. Moreover, although daily diary and experimental studies among civilians have found negative associations between alcohol use and sleep, these patterns change with consecutive days of drinking and may differ for those with insomnia. This study measured (a) acute and cumulative day-level associations between sleep and alcohol use among heavy-drinking US veterans and (b) the extent to which insomnia moderates these associations.
