Falls, Elderly, Psychomotor exercise program, Whole body vibration
Brief summary
The aim of present study is to analyze and compare the effect of two exercise programs - psychomotor exercise program vs exercise combined program (psychomotor + whole body vibration) - on risk factors for falls of community-dwelling older adults who are fallers or are at high risk of falling. This experimental study is a randomized controlled trial. The program will run for 24 weeks (3 sessions / week of 75 minutes), followed by 12 weeks of follow-up without intervention. Participants of the groups will be assessed 1) at baseline, 2) at 12 weeks, 3) at 24 weeks, and 4) after the follow-up. Participants will be randomly allocated to three groups: experimental group 1 (psychomotor program); experimental group 2 (combined program) and control group.
Detailed description
Aging is associated with a decline in executive functions, negatively influencing the motor, social and emotional capacities of older adults. (1) These losses will contribute to increase the risk of falling, so much that most falls occur during the performance of a dual-task (DT) (2). The lack of balance, strength and poor body composition are seen as causes of falls, and should therefore be considered in the prevention programs of these events in older adults. (3-5) A psychomotor exercise program uses the body and movement as mediators, relying on the prevention of cognitive, sensory, perceptive, emotional and affective deterioration, exploring the neuroplasticity. (6,7) Therefore, this sensorimotor and neurocognitive program may prevent falls, but it is important to analyze its real impact in reducing either falls or the risk factors for falls in the older adults. No studies focusing on this subject were found. The intervention through the whole body vibration (WBV) is referred in the literature as promoting the improvement of balance, mobility and agility, and preventing falls in the older adults.(8,9) WBV will have long-term therapeutic effects promoting the increase of muscle strength and increased bone mineral density. (10) Being two intervention methods with potential good results on falls prevention, it is not known whether there will be additional benefits in an intervention that combines both methods.
Interventions
OTHERPsychomotor exercise program
Each session includes: beginning ritual (5 min), warm-up (15 min), main section comprising the multimodal exercises (40 min), cool-down (10 min), and finishing ritual (5 min). At the initial stage, the activation of different muscle groups will be performed, providing an elevation of the neurophysiological parameters. The main section (multimodal exercises) will be focused on the specific objectives through sensorimotor and neurocognitive activities. This section includes periods ranging 10-15 min of exercises mainly focused on motor stimulation- physical performance (cardiovascular, strength, balance, flexibility, agility and movement accuracy)- alternating with exercises mainly focused on cognitive stimulation- executive functions (planning ability, information processing speed, attention and dual-task performance). At the cool-down the participants will normalize their physiological parameters. Finally, at the finishing ritual the participants share their sensations experienced.
The EG2 intervention combines the psychomotor exercise program with a WBV program. The program integrates 3 sessions / week of 75 minutes (including the 6 minutes of WBV) on alternated days. The WBV will integrate 3 sessions / week of 6 minutes each, with programed increased exercise time, series, and frequencies throughout the intervention.
