“…Osteoarthritis, the most common type of arthritis, is a painful and highly disabling chronic condition affecting roughly 630 million people worldwide (Udgata, 2014). The disease most commonly affects the joints in the knees, hands, feet and spine and is relatively common in the shoulder and hip joints (Wittenauer, Smith, & Aden, 2013).…”

This study analyzes the existence of the added worker effect (AWE) when a male partner suffers a health shock (negative health event), by using the information from the Chilean Social Protection Survey. The health shocks considered in this study are new cases of arthritis, asthma and hypertension. We find that neither asthma nor hypertension diagnosis generates an AWE. In the case of arthritis, the study shows differentiated effects by age cohorts. More specifically, we find that women's probability of labor force entry over three years increases by 50 percentage points when the husband between the ages of 18-44 is diagnosed with arthritis. This effect disappears in older age groups, which suggests that when studying the effect of health shocks, the differences between life cycle stages should be considered (chronic disabling conditions are an important source of financial risk for young households).

“…The hallmark symptom of OA is chronic joint pain, which contributes to functional limitation and is a major cause of reduced quality of life. OA is the leading cause of disability affecting up to 15% of the global population, that equates to approximately 630 million people worldwide [ 6 ]. In South America, the prevalence of arthritis and rheumatism has been reported to range between 23.8 and 56.0% [ 7 ].…”

BackgroundKnee osteoarthritis (OA) has been linked to maladaptive plasticity in the brain, which may contribute to chronic pain. Neuromodulatory approaches, such as Transcranial Direct Current Stimulation (tDCS) and Peripheral Electrical Stimulation (PES), have been used therapeutically to counteract brain maladaptive plasticity. However, it is currently unclear whether these neuromodulatory techniques enhance the benefits of exercise when administered together. Therefore, this protocol aims to investigate whether the addition of tDCS combined or not with PES enhances the effects of a land-based strengthening exercise program in patients with knee OA.MethodsPatients with knee OA (n = 80) will undertake a structured exercise program for five consecutive days. In addition, they will be randomized into four subgroups receiving either active anodal tDCS and sham PES (group 1; n = 20), sham tDCS and active PES (group 2, n = 20), sham tDCS and PES (group 3, n = 20), or active tDCS and PES (group 4, n = 20) for 20 min/day for five consecutive days just prior to commencement of the exercise program. The primary outcomes will be subjective pain intensity (VAS) and related function (WOMAC). Secondary outcomes will include quality of life (SF-36), anxiety and depression symptoms (HAD), self-perception of improvement, pressure pain thresholds over the knee, quadriceps strength, and quadriceps electromyographic activity during maximum knee extension voluntary contraction. We will also investigate cortical excitability using transcranial magnetic stimulation. Outcome measures will be assessed at baseline, 1 month after, before any intervention, after 5 days of intervention, and at 1 month post exercise intervention.DiscussionThe motor cortex becomes less responsive in knee OA because of poorly adapted plastic changes, which can impede exercise therapy benefits. Adding tDCS and/or PES may help to counteract those maladaptive plastic changes and improve the benefits of exercises, and the combination of both neuromodulatory techniques must have a higher magnitude of effect.
