The study included 124 patients with an average age of 68 years admitted to the Department of Neurology at the Second People's Hospital of Neijiang. Family support was assessed with the Family Support Questionnaire (FSQ) and Family APGAR Questionnaire. The primary outcome was functional independence at 6 months, defined as a modified Rankin Scale (mRS) score of 0–2. Higher FSQ scores (10–15) were significantly associated with better functional independence compared with scores of 0–5 (OR: 1.666, 95% CI 1.236–2.214, P < 0.001). However, APGAR score was not significantly associated with functional recovery (P > 0.05). Higher FSQ and APGAR scores were associated with better treatment adherence (P < 0.001), whereas lifestyle improvement did not differ between levels of family support (P > 0.05). The study concludes that family support is positively associated with functional recovery and adherence to treatment.
