• Anodal tDCS over M1 reduces pain in people with chronic CHIKV arthralgia. • tDCS may provide functional benefits in chronic CHIKV arthralgia. • tDCS is an easy to use and low-cost intervention that could be used for arthralgia. Chikungunya virus (CHIKV) is a globally prevalent pathogen, with outbreaks occurring in tropical regions. Chronic pain is the main symptom reported and is associated with decreased mobility and disability. Transcranial direct current stimulation (tDCS) is emerging as a new therapeutic tool for chronic arthralgia. To evaluate the effectiveness of 10 consecutive sessions of anodal tDCS on pain (primary outcome) in participants with chronic CHIKV arthralgia. Secondary outcomes included functional status, quality of life, and mood. In this randomized, double-blind, placebo-controlled trial, 30 participants with chronic CHIKV arthralgia were randomly assigned to receive either active (n = 15) or sham (n = 15) tDCS. The active group received 10 consecutive sessions of tDCS over M1 using the C3/Fp2 montage (2 mA for 20 min). Visual analog scale of pain (VAS), health assessment questionnaire (HAQ), short-form 36 health survey (SF-36), pain catastrophizing scale, Hamilton anxiety scale (HAS), timed up and go (TUG) test, lumbar dynamometry, 30-s arm curl and 2-min step test were assessed at baseline, day 10 and at 2 follow-up visits. There was a significant interaction between group and time on pain (p = 0.03; effect size 95 % CI 0.9 (-1.67 to -0.16), with a significant time interaction (p = 0.0001). There was no interaction between time and group for the 2-minute step test (p = 0.18), but the groups differed significantly at day 10 (p = 0.01), first follow-up (p = 0.01) and second follow-up (p = 0.03). HAQ and SF-36 improved but not significantly. There was no significant improvement in mental health, and physical tests. tDCS appears to be a promising intervention for reducing pain in participants with chronic CHIKV arthralgia, although further research is needed to confirm these findings and explore potential long-term benefits.

• BENECA mHealth improved cognitive symptoms after cancer. • mHealth plus multimodal rehabilitation at least doubled the effect size. • This study supports the role of occupational therapy in oncology. • Rehabilitation techniques should be individualised. Medical and surgical treatments for breast cancer have various adverse effects. Both mobile health and supervised intervention strategies have been implemented to overcome these effects, but some gaps remain to be addressed. Scientific evidence for the effectiveness of occupational therapy in cancer is limited. To compare the clinical effectiveness of the BENECA mHealth app used alone or combined with an integral supervised rehabilitation strategy that focused on cognitive performance, mood state, functional capacity, and cancer-related pain and fatigue in overweight women after breast cancer. In this secondary analysis of an assessor-blinded randomized controlled clinical trial, 80 overweight women after breast cancer (stage I-IIIA) were randomly allocated to an integral approach group (IA; n =40) or a control group (CG; n =40). All participants participated in an 8-week intervention. Assessments were performed at baseline, 8 weeks, and 6 months and included cognitive performance (Trial Making Test and Wechsler Adult Intelligence Scale), psychological state (Hospital Anxiety and Depression Scale), pain (Brief Pain Inventory), fatigue (Piper Fatigue Scale), and physical function (6 min walk test). An intention-to-treat analysis was conducted with analysis of covariance. Selective attention (TMT) was significantly higher in the IA group, with a moderate to large effect size for TMT A (T2: d=1.1; T 3: d=1.2), working memory and processing speed (WAIS), anxiety and general HADS score (d =1.6), and functional capacity at 8 weeks and 6 months (d =1.5). Fatigue perception (mean difference, -0.6; 95% CI -1.4 to 0.04; p =0.009) and pain (intensity level p <0.001; interference level p =0.002) were also significantly more improved in the IA group. An integral strategy involving the BENECA mHealth app with a supervised, multimodal intervention improved cognitive, psychological, and functional performance in women after breast cancer more than mHealth alone. Occupational therapy has a role to play in breast cancer rehabilitation. [ABSTRACT FROM AUTHOR]
