Mixed methods evaluation of a self-management group programme for patients with neuromuscular disease and chronic fatigue

Patient perspectives on, and effects of, medication management in geriatric fallers (the EMMA study): protocol for a mixed-methods pre-post study

INTRODUCTION

Pharmacotherapy is critical in geriatric fallers owing to the vulnerability of this population. Comprehensive medication management can be an important strategy to reduce the medication-related risk of falling in this patient group. Patient-specific approaches and patient-related barriers to this intervention have rarely been explored among geriatric fallers. This study will focus on establishing a comprehensive medication management process to provide better insights into patients' individual perceptions regarding their fall-related medication as well as identifying organisational and medical-psychosocial effects and challenges of this intervention.

METHODS AND ANALYSIS

The study design is a complementary mixed-methods pre-post study which follows the approach of an embedded experimental model. Thirty fallers aged at least 65 years who were on five or more self-managed long-term drugs will be recruited from a geriatric fracture centre. The intervention consists of a five-step (recording, reviewing, discussion, communication, documentation) comprehensive medication management, which focuses on reducing the medication-related risk of falling. The intervention is framed using guided semi-structured pre-post interventional interviews, including a follow-up period of 12 weeks. These interviews will assess patients' perceptions of falls, medication-related risks and gauge the postdischarge acceptability and sustainability of the intervention. Outcomes of the intervention will be measured based on changes in the weighted and summated Medication Appropriateness Index score, number of fall-risk-increasing drugs and potentially inadequate medication according to the Fit fOR The Aged and PRISCUS lists. Qualitative and quantitative findings will be integrated to develop a comprehensive understanding of decision-making needs, the perspective of geriatric fallers and the effects of comprehensive medication management.

ETHICS AND DISSEMINATION

The study protocol was approved by the local ethics committee of Salzburg County, Austria (ID: 1059/2021). Written informed consent will be obtained from all patients. Study findings will be disseminated through peer-reviewed journals and conferences.

Exercise in myositis: What is important, the prescription or the person?

Our aim for this narrative review was to undertake a search of studies into exercise for people living with Idiopathic Inflammatory myopathies (IIM). We explored the strength of existing evidence with a particular consideration for the implications for people living with IIM and what is important to them. The search strategy from the 2021 Cochrane Physical Activity review in neuromuscular disease was used, and we selected articles that included people with IIM, including Dermatomyositis (DM), Inclusion Body Myositis (IBM), Immune Mediated Necrotising Myopathy (IMNM) [also known as necrotizing autoimmune myopathy (NAM)], and Polymyositis (PM). 2967 records were screened and 16 were included in this review. Safety of exercise was demonstrated in nine articles, using a range of measures of disease activity, serum creatine kinase, indicators of inflammation, pain, or fatigue. Two studies that took muscle biopsies showed no evidence of increased inflammation. Aerobic exercise protocols were used in 8 studies across conditions and demonstrated improvements in cardiorespiratory fitness or exercise capacity. Six studies of strength training observed improvements in muscle function, with two studies reporting muscle biopsy results of amplified immune response and up regulation of genes related to recycling of damaged proteins. Nine of 13 studies that measures functional outcomes showed significant improvements, and evidence for behaviour change was observed in a study of a self-management intervention. The evidence of safety and effect of training is reassuring and welcome, and we now need to explore how we support people to incorporate exercise and physical activity longer term into active lifestyles.

Explanatory factors of dynamic balance impairment in myotonic dystrophy type 1

INTRODUCTION/AIMS

Myotonic dystrophy type 1 (DM1) is a neuromuscular disease affecting many systems and for which muscle weakness is one of the cardinal symptoms. People with DM1 also present with balance-related impairments and high fall risk. The aim of this study was to explore explanatory factors of dynamic balance impairment in the DM1 population.

METHODS

A secondary analysis of data collected as part of a larger study was performed. The Mini Balance Evaluation System Test (Mini-BESTest) was used to assess dynamic balance. Age, sex, and CTG repeat length in blood were retrieved from medical records and research files. The maximal isometric muscle strength of five lower limb muscle groups (hip flexors and extensors, knee flexors and extensors, and ankle dorsiflexors) was quantitatively assessed as well as fatigue. Standard multiple regression analysis was used.

RESULTS

Fifty-two individuals (31 men) aged between 24 and 81 years were included. The final model explains 65.9% of the balance score; ankle dorsiflexor muscle strength was the strongest explanatory factor, followed by CTG repeat length, age and fatigue to a lesser extent.

DISCUSSION

Dynamic balance is impaired in people with DM1. Results of this study suggest that rehabilitation interventions aimed at improving strength of the ankle dorsiflexors and managing fatigue could help to improve dynamic balance in this specific population.
