Study type
Interventional
Description of intervention(s) / exposure
There are two groups, experimental and control group. Both groups formed by subjects Diagnosed with Alzheimer's disease.
The experimental group participated in a geriatric revitalization program with a physical activity, with sessions in homogeneous groups (groups of 5-8 subjects with similar cognitive impairment) for 6 months with a frequency of 3 sessions per week of 40-45 minutes, carried out in a Center specialized in the treatment of patients with Alzheimer's disease.
The sessions were conducted by a physiotherapist with more than 5 years of experience in the treatment of people with disabilities, dementias and Alzheimer's disease.
The sessions of geriatric revitalization are structured:
To start the session warm-up exercises are performed (walking, general exercises of joint mobility, with wide ranges of movement of upper and lower limbs and cervical spine fundamentally, during 3 minutes) and muscle stretching (gentle stretching of the main muscle groups of upper and lower limbs and the cervical spine, each one during 10 seconds and 2 repetitions). Aerobic endurance exercises are then performed (walking and depending on the capacity of the subjects of the group, the intensity can be increased almost to run, in two times, the first during 3 minutes and the second during 5-6 minutes, alternated with series of specific joint mobility of upper and lower limbs, normaly 2 sets of 10 repetitions each mobilization). Muscular strength (exercises with weights, manual resistance of the physiotherapist, elastic rubber bands, normaly 2 sets of 10 repetitions each exercise). Coordination, agility and balance exercises that can vary in duration according to the session and finally breathing exercises and relaxation to end the session.
At all times, the theoretical maximum heart rate (220-age) must be respected (periodically the heart rate is checked)

Statistical methods / analysis
Recruitment was for a non-probabilistic sample for convenience and consecutive when the subjects requested admission to the State Reference Center of Care for People with Alzheimer's Disease and other Dementias. Therefore, the calculation of the sample size was subject to the admission requests during the time of the study.
Some data was analysed, and other will be analysed by using the IBM-SPSS software package (version 23.0).
Means and standard deviations were calculated for each variable.
ANOVA test ( p > 0.05) was used at baseline to compare quantitative data of groups and a chi square test was used for categorical data.
Multivariate analysis of variance (MANOVA) with repeated measures will be used to assess differences between groups, with covariants, and pair-wise comparisons post-hoc.
The statistical analysis will be conducted at a 95% confidence level. A p-value < 0.05 will be considered to indicate statistical significance in all analyses.

Summary
Brief summary
Main objective: to verify the efficacy of the Geriatric Revitalization Program, as a physical activity, on gait and balance through functional tests, the risk of falling and the values of bone mineral density in people diagnosed with Alzheimer's Disease.
Hypothesis 1: The application of a Geriatric Revitalization Program, as a physical activity, decreases the risk of falls in people diagnosed with Alzheimer's disease, improving gait and balance as functional parameters.
Hypothesis 2: The application of a Geriatric Revitalization Program, as a physical activity, reduces the loss of bone mineral density in people diagnosed with Alzheimer's disease.
