Eligibility
Age
65 Years to No maximum
Inclusion criteria
Inclusion criteria: To participate in the study, the eligibility criteria are: being over 65 years old; having fallen at least once in the last six months; walking independently and not participating in any fall prevention program.
Exclusion criteria
Exclusion criteria: Exclusion criteria from the study will be: presenting neurological disorder, scoring less than 24 on the Mini Mental State Examination (MMSE, Annex A); severe osteoarticular problems, presenting any ischemic heart disease that limits physical exercise; chronic obstructive pulmonary disease (COPD) and/or uncontrolled blood pressure. For ethical purposes, all study participants will be invited to carry out the group protocol contrary to the end of the experiment.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The stability margin will be considered as the primary outcomes of this study, which will be measured using the concept of Extrapolated Center of Mass (XCoM). The center of mass will be determined using a simplified model with the use of only four retroreflective markers in specific locations (trochanter of the right leg, seventh cervical vertebra (C7), left and right forefoot). These markers will be tracked by nineteen cameras of the Optitrack® motion capture system (Optical Motion Capture Solutions) at an acquisition frequency of 100 Hz. Another primary outcome will be the number of falls during the intervention protocols, which will be evaluated using as a criterion the 30% reduction in ground reaction force quantified through four load cells located at the base of the treadmill during walking. | — |
Secondary
| Measure | Time frame |
|---|---|
| The number of falls and falls with injury reported in the six months following disturbance-based balance training (TEBP) will be considered as secondary outcomes of this study, which will be measured through the diary of falls given to the volunteers and through follow-up by telephone. monthly for six months, questioning whether there were new falls after training and how these falls were. Another variable will be dynamic balance assessment through the MiniBEST Test and fear of falls through the Falls Efficacy Scale (FES-I), which will be performed during the study retention period and at the six-month follow-up of the study. | — |
