Dosage of joint mobilization for the management of patients with rotator cuff-related shoulder pain: A scoping review.

BACKGROUND: Evidence supporting type and dosage of joint mobilizations and rationale for selecting joint mobilization dosage for patients with rotator cuff-related shoulder pain are limited. OBJECTIVES: This scoping review aimed to systematically map the type and dosage of joint mobilizations used in previous trials for managing patients with rotator cuff-related shoulder pain; and summarize the rationale for adopting a specific joint mobilization dosage. METHODS: We searched six databases. We included randomised controlled trials using joint mobilization for patients with rotator cuff-related shoulder pain. We extracted data regarding technique, treatment joint mobilization dosages and rationale for a specific dosage. RESULTS: We included 32 studies. Most studies did not or partially report technique (67%) and within-session dosage (64%) of passive joint mobilization. Overall treatment was fully reported in 95% of studies. The dosage used for passive joint mobilization was heterogeneous (ranging from grade I to grade V). Most studies (85%) did not or partially report technique of mobilization with movement (MWM), whereas within-session and overall treatment dosages were fully reported in more than 85% of studies. Three sets of 10 repetitions were commonly used within-session dosage for MWM. We found very limited information on the rationale for selecting dosage of joint mobilization. CONCLUSION: We found limited information about the dosage or the rationale for selecting joint mobilization, with a heterogeneous dosage being tested across trials. Our findings highlight the importance of detailed reporting for dosage and rationale for selecting a specific dosage of joint mobilization.

Autonomic nervous system and endocrine system response to upper or lower cervical spine mobilization in males with persistent post-concussion symptoms: a proof-of-concept trial.

INTRODUCTION: The peripheral stress response, consisting of the autonomic nervous system (ANS) and hypothalamic pituitary adrenal-axis (HPA-axis), functions to maintain homeostasis in response to stressors. Cervical spine manual therapy has been shown to differentially modulate the stress response in healthy populations. No study has investigated whether cervical spine mobilizations can differentially modulate the stress response in individuals with persistent post-concussion symptoms (PPCS), a population characterized by a dysfunctional stress response. METHODS: A randomized, controlled, parallel design trial was performed to investigate whether upper or lower cervical spine mobilization can differentially modulate components of the stress response in individuals with PPCS. The outcomes were salivary cortisol (sCOR) concentration (primary) and the HRV metric, rMSSD, measured with a smartphone application (secondary). Nineteen males diagnosed with PPCS, aged 19-35, were included. Participants were randomly assigned into either intervention group, upper (n = 10) or lower (n = 9) cervical spine mobilization. Each outcome was collected at different time points, pre- and post-intervention. Statistical analyses were performed using the Friedman's Two-Way ANOVA, Mann-Whitney U test, and Wilcoxon Signed Rank Test. RESULTS: There was a statistically significant within-group reduction in sCOR concentration 30 minutes following lower cervical spine mobilizations and statistically significant within-group increase in rMSSD 30 minutes following upper cervical spine mobilizations. CONCLUSION: The results of this trial provide preliminary evidence for cervical spine mobilizations to differentially modulate components of the stress response at specific time points. Understanding the mechanisms of the effect of cervical spine mobilizations on the stress response provides a novel rationale for selecting cervical spine mobilizations to rehabilitate individuals with PPCS.

Scaling-Up eConsult: Promising Strategies to Address Enabling Factors in Four Jurisdictions in Canada.

BACKGROUND: Effective healthcare innovations are often not scaled up beyond their initial local context. Lack of practical knowledge on how to move from local innovations to large-system improvement hinders innovation and learning capacity in health systems. Studying scale-up processes can lead to a better understanding of how to facilitate the scale-up of interventions. eConsult is a digital health innovation that aims to connect primary care professionals with specialists through an asynchronous electronic consultation. The recent implementation of eConsult in the public health systems of four Canadian jurisdictions provides a unique opportunity to identify different enabling strategies and related factors that promote the scaling up of eConsult across jurisdictions. METHODS: We conducted a narrative case study in four Canadian provinces, Quebec, Ontario, Manitoba, and Newfoundland & Labrador, over a 3-year period (2018-2021). We observed provincial eConsult committee meetings (n=65) and national eConsult forums (n=3), and we reviewed internal documents (n=93). We conducted semi-structured interviews with key actors in each jurisdiction (eg, researchers, primary care professionals, specialists, policy-makers, and patient partners) (n=40). We conducted thematic analysis guided by the literature on factors and strategies used to scale up innovations. RESULTS: We identified a total of 31 strategies related to six key enabling factors to scaling up eConsult, including: (1) multi-actor engagement; (2) relative advantage; (3) knowledge transfer; (4) strong evidence base; (5) physician leadership; and (6) resource acquisition (eg, human, material, and financial resources). More commonly used strategies, such as leveraging research infrastructure and bringing together various actors, were used to address multiple enabling factors. CONCLUSION: Actors used various strategies to scale up eConsult within their respective contexts, and these helped address six key factors that seemed to be essential to the scale-up of eConsult.
