The Influence Of Physiological And Psychological Factors On Fall Syndrome

Fall Syndrome: The Influence Of Physiological And Psychological Factors On Behavior After Falls Principal Investigator

Most of previous studies are cross-sectional studies, and rarely explore the changes in physical activity, mental state, cognitive and motor functions over time after a fall. Therefore, we hope to find out what changes in the elders' physiological and psychological functions after a fall.

Study Overview

• Status: Completed
• Conditions: Fall

Detailed Description

Falls are the main cause of accidental injuries that are common among the elderly. In Taiwan, the incidence of falls is about 15% to 34%. Falling can cause subsequent serious injuries and post-fall syndromes. Post-fall syndrome is common after a fall. The symptoms of self-restricted activity for fear of falling again affect about one-fifth of older fallers. This syndrome develops within a short period of time after a fall, which not only causes serious problems but also affects psychological symptoms and dependence on daily life functions. All of these reduce the function of movement and increase the chance of falling again. However, most of the past studies are cross-sectional studies, and rarely explore the changes in physical activity, mental state, cognitive and motor functions over time after a fall. Therefore, the study will investigate the changes in physiological and psychological functions after a fall among older adults who experiences a recent fall within 2 months. Additionally, the physiological and psychological functions will be compared between older adults with and without a history of falls.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Visual acuity	Vision acuity will be measured by the Snellen Chart. The Snellen chart is printed with eleven lines of block letters. The first line consists of one very large E letter. Subsequent rows have increasing numbers of letters with decrease in size. Participant will take the test by covering one eye from 6 meters away, and read aloud the letters of each row, beginning at the top. The smallest row that can be read accurately indicates the visual acuity in that specific eye.	Baseline
Vertigo symptom	Situational Vertigo Questionnaire (SVQ) consists of 19 questions, with a score from 0 (not at all), 1 (very slightly), 2 (somewhat), 3 (quite a lot) to 4 (very much). It measures how frequently symptoms (unusual disorientation, dizziness, giddiness, light-headedness or unsteadiness) are provoked or exacerbated in environments with visual-vestibular conflict or intense visual motion e.g. busy supermarket aisles. A score is obtained by dividing the total sum for activities experienced by the number of activities.	Baseline
Medication history	Medication history will be recorded including drug name, dose, route, and frequency.	Baseline
Static balance	Static balance test will be assessed by the modified Clinical Test for Sensory Interaction in Balance(mCTSIB), The mCTSIB was developed as a clinical version of the Sensory Organization Test and was developed to assess sensory contributions to postural control. Participants will stand with their hands at their sides, feet together and perform the following 4 sensory conditions: (1) Stand on firm surface, eyes open (2) Stand on firm surface, eyes closed (3) Stand on foam surface, eyes open (4) Stand on foam surface, eyes closed. Each condition will be timed for maximum 30 seconds. The test is terminated when a participant's arms or feet move. If a participant is unable to maintain the position for 30 seconds they are provided with 2 additional attempts. The time (s) to complete each condition will be recorded.	Baseline
Dynamic balance	Dynamic balance test will be evaluated by the functional reach test. The participant will be instructed to stand next to a wall and position the arm that is closer to the wall at 90 degrees of shoulder flexion. The assessor instructs the participant to "Reach as far as you can forward without taking a step." The distance (cm) from the start to end position at the middle fingertip will be measured.	Baseline
Walking ability	Walking ability test will be measured by the 10 meter walk test. Participant will be asked to walk on a 14 meters walkway at their comfortable speed. The time for the middle 10 meters will be recorded and walking speed (m/s) will be calculated.	Baseline
Hand grip	Dominant hand grip (kg) will measured by a dynamometer. Participants will stand with their arms down by their sides. They will squeeze the dynamometer with maximum isometric effort, which is maintained for 6 seconds.	Baseline
Lower limbs strength	Lower limbs strength will be assessed by the Five Times Sit to Stand. Participants will be asked to sit on the chair with arms folded across their chest, and stand up and sit down as quickly as possible for 5 times. The time (s) to complete the task will be recorded.	Baseline
Function ability	Function ability test will be determined by the timed up and go test (TUG). Participants will be asked to rise from a chair, walk three meters, turn around, walk back to the chair, and sit down. The time (s) to complete the task will be recorded.	Baseline
Cognitive function (mild cognitive impairment)	Cognitive function will be evaluated by the Montreal Cognitive Assessment (MoCA), which covers visuospatial abilities, short-term memory recall task, multiple aspects of executive functions, attention, concentration, and working memory. The total score is 30 and cut-off point is 26. Score less than 26 indicates mild cognitive impairment.	Baseline
Cognitive function (dementia)	Mini-Mental State Examination(MMSE) is used extensively in clinical and research settings to measure cognitive impairment, covering attention, calculation, recall, language, ability to follow simple commands and orientation. It is commonly used in medicine and allied health to screen for dementia; used to estimate the severity and progression of cognitive impairment and to follow the course of cognitive changes in an individual over time; thus making it an effective way to document an individual's response to treatment.	Baseline
Fear of falling	Fear of falling will be measured by the Falls Efficacy Scale International(FES). The FES rated each daily task from no confident at all to completely confident. The total score between 16 and 64, and the score more than 28 indicates higher level of fear of falling.	Baseline
The confidence of balance	The confidence of balance will test by Activities-specific Balance and Confidence (ABC) Scale. The ABC Scale is a 16-item questionnaire. Each item is rated from 0% (no confidence) to 100% (complete confidence) by all participants. The higher score, the more confidence they have.	Baseline
Depression Anxiety and Stress	Depression, anxiety and stress will be assessed by the Depression Anxiety and Stress(DASS-21). It is a self-reported scale designed to measure the negative emotional states of depression, anxiety and stress. The higher score indicates the increased severity of symptoms.	Baseline
Sarcopenia	Sarcopenia will be screened by the SARC-F including how much difficulty do you have in lifting and carrying 10 pounds, how much difficulty do you have walking cross a room, how much difficulty do you have transferring from a chair or bed, how much difficulty do you have climbing a flight of 10 stairs, and how many times have you fallen in the past year. The score more than 4 indicates high risk of sarcopenia.	Baseline
Frailty	Frailty will be assessed by the Fried frailty phenotype. It is a yes-no model based on five items including physical inactivity, low muscle strength, slow gait speed, exhaustion/ fatigue and weight loss. Each item is scored as 0 (no) or 1 (yes). The score of greater than 3 indicates frailty.	Baseline
Basic Activity of Daily Living	Basic activities of daily living will be measured by the Barthel Index. It is an ordinal scale used to measure performance in activities of daily living (ADL). Ten variables describing ADL and mobility are scored, a higher number being a reflection of greater ability to function independently following hospital discharge. Time taken and physical assistance required to perform each item are used in determining the assigned value of each item. The Barthel Index measures the degree of assistance required by an individual on 10 items of mobility and self care ADL. The score of 0-20 indicates "total" dependency, 21-60 indicates "severe" dependency, 61-90 indicates "moderate" dependency, and 91-99 indicates "slight" dependency.	Baseline
Instrumental Activity of Daily Living	Instrumental activities of daily living (IADL) will be measured by the Lawton Instrumental Activities of Daily Living Scale which assesses a person's ability to perform tasks such as using a telephone, doing laundry, and handling finances. It contains eight items, with a summary score from 0 (low function) to 8 (high function).	Baseline
Health-related quality of life	The quality of life will be assessed by the Control, Autonomy, Self-Realization and Pleasure (CASP-19), which has 4 subscales and 19 items in total. A 4-point Likert scale is used including "often", "sometimes", "not often" and "never". The higher score indicates the better quality of life.	Baseline
Physical Activity	Physical Activity will be examined by the International Physical Activity Questionnaire (IPAQ)-Short Form. Participants will be asked about their duration (in minutes) and frequency (days) when performing four specific types of activity: walking, moderate intensity, vigorous intensity and sitting.	Baseline
Social function survey	Participants will be asked whether they have been in contact with family or friends in the past six months. According to the scale of different networks, the frequency of interaction and the degree of closeness, interpersonal relationships and social support networks can be determined.	Baseline
