Immediate and Long-Term Effectiveness of a Therapeutic Exercise Protocol in Patients with Dementia

Background/Objectives: Therapeutic exercise (TE) has been shown to be an effective tool for slowing physical and cognitive decline in patients with dementia. However, its true impact on physical and functional variables, as well as the duration of its effects once therapy is discontinued, remains unclear. The aim was to analyze the short- and medium-term effects of a structured and monitored TE program on motor function in patients with dementia. Methods: A pre-post clinical trial was conducted in individuals with a medical diagnosis of mild-to-moderate cognitive impairment (Mini-Mental State Examination scores between 10 and 23) who had not engaged in regular exercise during the previous 6 months. The study variables and their measurement tools included general motor function (Short Physical Performance Battery), trunk control (Trunk Control Test), balance (Berg Balance Scale), overall mobility and gait (Timed Up and Go Test), and degree of independence in activities of daily living (ADLs) (Barthel Index). Participants completed a 12-week TE intervention at moderate intensity, 3 days per week for 45 min sessions. The program included aerobic training and strength, coordination, flexibility, and balance exercises. TE intensity was monitored through heart rate and dynamic maximal resistance. Assessments were conducted at baseline (t0), immediately after the program (t1), and 6 months after completion (t2). Results: Significant global longitudinal effects of time were observed for general motor function, balance, trunk control, and mobility and gait, whereas no significant global effect was detected for independence in activities of daily living. Post-intervention changes were non-significant; however, several pairwise comparisons showed moderate-to-large effect sizes. Follow-up assessments revealed shifts in performance distributions consistent with functional decline. Conclusions: A structured TE program performed at moderate intensity may help slow or attenuate the physical decline experienced by individuals with dementia.
