What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT07388186). This is a study registration, not published results. Lead sponsor: University of Salamanca. Recruitment status: COMPLETED. Phase: NA. Study type: INTERVENTIONAL. Enrollment: 43 participants (ACTUAL). Conditions: Frailty, Caregiver Burden, Anxiety. Interventions: BEHAVIORAL: Progressive Muscle Relaxation; BEHAVIORAL: Functional Strength Training. Primary outcome measures: Frailty , Baseline, 3-month follow-up and immediately after completion of the intervention (at 10 weeks).. Brief summary: Informal caregivers of people with Alzheimer's disease experience high physical and psychological burden, increasing their risk of frailty, anxiety, and caregiver burnout. This randomized controlled trial aims to evaluate the effectiveness of a combined strength training and progressive muscle relaxation program compared with progressive muscle relaxation alone. The intervention will last 10 weeks, with assessments conducted at baseline, post-intervention, and at a 3-month follow-up. Primary outcomes include frailty, anxiety, and caregiver burden.
