Article Abstract
Background: Contingency management (CM) interventions involve providing reinforcement for engaging in a desired behavior, and have been shown to increase treatment adherence and promote abstinence in the treatment of substance use disorders. This review was conducted to systematically review the literature on the effectiveness of CM when applied to a range of medical conditions outside of substance use disorders.
Method: The authors identified a total of 24 randomized studies examining the effects of CM on four outcomes: weight change, physical activity, medication/device adherence, and viral load that were included in the qualitative summary, and 20 studies included in the meta-analysis.
Results: CM was associated with positive outcomes for physical activity and medication/device adherence compared to control conditions. Findings with weight loss and viral load were more mixed, and evidence for publication bias was found for both outcomes. The effects of CM tend to dissipate when the contingency is removed. Heterogeneity was observed across most outcomes.
Limitations And Conclusions: This review provides preliminary support for the use of CM in increasing physical activity and improving adherence to medication for chronic health conditions while reinforcement is ongoing. Future studies should examine potential moderators and identify strategies to maintain these changes over time.

Effect of knee joint position on soleus muscle function during isokinetic plantarflexion.

Purpose: Contribution of the gastrocnemii muscles to ankle moment is influenced by the knee joint position because they span the knee and the ankle joint as well. However, limited information is available on the effect of knee joint position on soleus activation under dynamic plantarflexion, hence the aim of this study was to investigate if soleus have a compensatory strategy in fascicle behavior or EMG activity during knee flexed plantarflexion in order to reduce the magnitude of the decrement in ankle moment.
Equipment And Methods: Isokinetic dynamometry with EMG and ultrasound measurements was used to estimate medial gastrocnemius and soleus behavior during knee flexed and extended plantarflexions using three angular velocities.
Effectiveness of backward walking exercises combined with conventional rehabilitation programs on managing pain intensity and disability in patients with knee osteoarthritis: A systematic review and meta-analysis of randomized controlled trials.

Background: Knee osteoarthritis (OA) causes pain and diminishes quality of life. Backward walking exercise (BWE) has been shown to improve lower muscle strength and reduce knee adduction moment, making it a recommended intervention for knee OA rehabilitation. This study aims to evaluate the effectiveness of BWE combined with conventional rehabilitation programs on pain intensity and disability among individuals with knee OA.

Latent profile analysis (LPA) is in the finite mixture model analysis family and identifies subgroups by participants' responses to continuous variables (i.e., indicators); participants' probable membership in each subgroup is based on the similarity between the subgroup's prototypical responses and the person's unique responses.

Purpose Of Review: Patients living with cancer are at risk for significant potential cardiovascular complications as a direct result of cancer treatment or due to underlying comorbid cardiovascular disease. This article reviews the methods of risk stratification as well as pharmacologic and nonpharmacologic approaches to cardioprotection in cardio-oncology.
Recent Findings: Several cancer-specific risk stratification tools have incorporated variables such as age, sex, cancer subtype, traditional cardiovascular risk factors and cancer treatment-related parameters to assess cardiovascular specific risk prior to cancer therapy.
