1 Department of Otolaryngology Head and Neck Surgery Department of Communication Sciences and Disorders Fall Prevention Program for Older Adults With a Fear of Falling Julie A. Honaker, Ph.D Robert W. Keith, Ph.D. Laura Kretschmer, Ed.D. Daniel Choo, M.D. Patrick Shumrick, DPT

2 An Aging Society Prediction for the US: By 2010, 40 million 65 years By 2040, 80 million 65 years 1. Girardi, M., Konrad, H.R., Amin, M., Hughes, L.F. (2001)

3 Boston, Massachusetts Population Estimates 1 : 680,000 Mean age = 32 years years = 27, years = 22,160 > 65 years = 76,

4 Epidemiology of Falls 30% to 50% of people 60 years or older will fall 10-20% repeatedly Elderly in nursing homes (rate rises to 50% will fall twice or more per year) 1. Rubenstein, L.Z. and Josephson, K.R. (2002).

5 Hip Fractures Major cause of morbidity and mortality In 1999, hip fractures resulted in nearly 338,000 hospital admissions 1 By 2050, hip fractures will exceed 600, Popovic, J.R.(2001) American Academy of Orthopaedic Surgeons (2006)

6 Risk Factors for Falls Broad range of risk factors identified in the literature (between 130 and 400) 1 Likelihood of falling increases with four or more risk factors 2 Classified as extrinsic or intrinsic 1. McMurdo, M. (2001). 2. Masud, T., Morris, O. (2001) 2. Nevitt, M.C., Cummings, S.R., Kidd, S., & Black, D. (1989).

7 Risk Factors for Falls Extrinsic Environmental Factors: Poor lighting Unsafe stairways Irregular floor surfaces

8 Risk Factors for Falls Intrinsic Decline in sensory system: Vestibular, vision and proprioception

9 Risk Factors for Falls Decline in motor Strength, coordination and endurance Increased age History of Falls Slow walking speed Decline in function and integration (response time/reaction time)

10 Risk Factors for Falls 1. Steinweg, K.K,, (1997). 50% of falls are due to a medical condition 1 Diabetes, Parkinson s disease, stroke, arthritis, osteoporosis Any acute or chronic disease Visual disorders Cataracts, glaucoma, macular degeneration Medications Type and number CNS disorder Balance disorders and dizziness*

11 Falls and the Older Adult Unfortunately, some older adults fail to seek help for falls Attribute these to normal aging Many older adults fear falling and do not realize that many falls they associate with aging can be prevented

12 Fear of Falling (FoF( FoF) Injuries can be treated/fear of another fall is persistent Fear of falling can: Create excessive anxiety Restrict participation in activities of daily living Decrease quality of life Increase dependence on others

13 Fear of Falling Definitions 1. Unusual variation of agoraphobia 1 2. Ptophobia 2 or post-fall syndrome 3 3. A lasting concern about falling that leads to individuals avoiding activities that he/she remains capable of performing 4 1. Marks, I., & Bebbington, P. (1976). 2. Bhala, R.P., O Donnell, J., & Thoppil, E. (1982). 3. Murphy, S.L., & Isaacs, B. (1982). 4. Tinetti, M.E., & Powell, L. (1993).

14 Fear of Falling Assessment Instruments Instrument Authors Item Response Scale Yes/No Question Tinetti et al = yes, 2 = no Falls Efficacy Scale (FES) Tinetti et al point confidence rating Activities Specific Balance Confidence Scale (ABC) Powell & Myers (1995) 0-100% Scale Survey of Activities and FoF in the Elderly (SAFFE) Lachman et al. (1998) Dichotomous yes/no, 4 point scale

15 Risk of Falling Programs

16 Risk of Falling Programs Multidisciplinary care (Fall Clinics) Exercise intervention programs Home hazard assessment/environment modification Studies incorporating these elements have established that falls and fall related injuries can be prevented Not easily replicated in most clinical settings Few have included FoF as an outcome of interest

17 Article Summary of Research Findings in the Reduction of Falling Concerns in Older Adults FoF assessment FoF Outcomes 8-session intervention = *Tennstedt et al. (1998) Modified FES reduction in FoF/this decayed by 6-month f/u *Taggart (2002) FES Signif icant decrease in FoF *Brouwer et al. (2003) ABC scale significant decrease in FoF for activity program only *Liu-Ambrose et al. (2004) ABC scale *Sattin et al. ABC scale (2005) FES improved balance confidence for resistance and agility groups no improved confidence for stretching group significant decrease in FoF for Tai Chi group * Study design aimed specifically at reducing fear of falling

18 Summary of Research Findings in the Reduction of Falling Concerns in Older Adults: Majority of studies were group programs Frail elderly (>75 years average age of inclusion) Few studies provided multidisciplinary fall prevention/risk of falling clinics, No audiologist/physical therapist/neurotologist (or otolaryngologist) for the initial evaluation

19 Summary of Research Findings in the Reduction of Falling Concerns in Older Adults: Few included home hazard assessment Excluded patients with complaints of vertigo, lightheadedness, etc Only 1 study provided qualitative descriptions from the subject;limited to patient satisfaction of the program None of the studies examined the impact of FoF on the patient or caregivers

20 Purpose of My Research To determine if intervention with a team approach risk of falling assessment and remediation program reduces fear of falling in older independent living individuals with a balance disorder. Evaluate the impact of FoF due to a balance disorder on the patient s activities of daily living Determine the impact of FoF on a selected family member, significant other, or spouse of the patient

21 Specific Aims 1. Establish/evaluate the impact of FoF due to a balance problem on selected family member, significant other or spouse 2. Verify level of anxiety and depression in the patient, due to FoF 3. Reveal the patient s present attitude toward their balance problem/activity level before FoF 4. Verify the effectiveness of the risk of falling intervention program designed to reduce FoF 5. Determine via the (ABC) Scale if the risk of falling program reduced FoF

22 Methods Male and female patients were recruited from individuals referred to the Balance Disorder Center (Group 1) Completed a balance disorder questionnaire One family member, significant other, or spouse of the patient was recruited for the study (Group 2)

23 Methods (Group 1) scheduled for 2 half days of risk of falling assessment Audiology and Physical therapist Testing was performed in 2 clinical settings Medical evaluation with neurotologist Remediation Portion (balance/vestibular rehabilitation with PT) Audiologist observed and interviewed patient/selected family member, spouse, or significant other before and after the remediation portion

24 Audiology Assessment (Group 1) 1. Reviewed balance questionnaire answers 2. Mini Mental State Exam 3. Geriatric Depression Scale 4. Beck Anxiety Inventory 5. Home Safety Checklist for Detection of Fall Hazards 6. Activities Specific Balance Confidence (ABC) Scale 7. Near vision acuity testing With and w/o corrective lenses Determined date of last eye examination

25 Audiology Assessment (Group 1) 8. Audiometric exam Tympanometry Acoustic reflexes Pure tone and speech audiometry 9. Balance assessment Platform Posturography Clinical Test of Sensory Integration and Balance (CTSIB) 10. Impaired balance function VNG

26 Significant Other Assessment (Group 2) 1. Mini-Mental State Examination 2. Home Safety Checklist for Detection of Fall Hazards 3. Modified ABC scale

27 Physical Therapy Assessment (Group 1) 1. Review of symptoms (fall history etc ) 2. Type and number of medications 3. Dizziness Handicap Inventory 4. Musculoskeletal examination Lower extremity strength, flexibility, reflex and sensation testing 5. Functional Reach Test 6. Timed Up and Go test 7. Examination of gait length and velocity 8. Berg Balance Test 9. Dynamic Gait Index

28 Neurotologist Assessment (Group 1) 1. Review of all risk of falling assessment results/case History 2. Head and neck examination Cranial nerve function/neurologic exam 3. All results integrated to yield diagnosis 4. Referral to PT for balance disorder remediation

29 Qualitative Assessment (Group 1 and 2) In home interview/observation 1 st interview scheduled prior to remediation portion of the program Separately interviewed (Group 1) and (Group 2) subjects w/ audiotape recorder Counseled/educated participants on the results of home hazard checklist Addressed home hazard issues

30 Remediation Program (Group 1) Balance/Vestibular Rehabilitation Designed to incorporate concerns/goals agreed upon by the PT and patient habituation, gaze stability, balance mobility, strength and endurance training Therapy sessions based on assessment results Length of program depended on indiv. objectives (on average 6-10 weeks)

31 Completion of Risk of Falling Program (Group 1 and 2) 1. Follow-up observation/interview 2. Separate interviews 3. (Group 1) post questionnaires: Geriatric Depression Scale Beck Anxiety Inventory ABC Scale 4. (Group 2) post questionnaire: Modified ABC scale

43 Qualitative Research: Example of Open Ended Questions Sample interview questions for patient with fear of falling: 1. Tell me about a typical day at home. 2. How has your life changed since the fear of falling? Sample interview questions for family member/spouse 1. Describe for me some activities your spouse/family member is afraid to perform to due the fear of falling. 2. Describe what activities your spouse/family member depends on you to perform due to his/her fear of falling.

44 Qualitative Results 1. Phenomenological approach 2. Open ended interview questions minutes (Group 1 & 2) 3. Content Analysis Transcribed (350 total pages) Group 1 = 172 pages, Group 2= 178 pages) Coded Coding example: No, I can walk through the house. Then sometimes I can t. It just depends on my day or if I m overly tired. Codes = description of balance problems, fatigue, limiting activities

45 Qualitative Results Content Analysis of 28 interviews yielded two Main Themes: Impact of a Fear of Falling/Balance Disorder on Daily Living Role of Risk of Falling Program

46 Data Display: Impact of a Fear of Falling/Balance Disorder on Daily Living Description of Fall/ Near Fall Experience Limiting activities/ lack of confidence Emotional Reaction of Participant since FoF Dependence on family members Family stress due to FoF/Balance problem Anxiety and Depression Problems with Family Members Problems with previous medical care Embarrassment due to FoF Discussion of Assistive Devices

47 Data Display: Role of Risk of Falling Program Overall Impression of Risk of Falling Program Change in Activity Level Post Program Limitations of the Remediation Program Increased Confidence Post Program Emotional Reaction Post Program Limiting Activities/ Dependence on Others Falls + Balance Problems not eliminated Education on Falls/Risk of Falling and Balance Problems Plans to Keep Up with Program Other Medical Concerns Post Program

48 Summary of Results: 1. All reported fall, FoF 2. High risk of falling 3. Statistically significant reduction in FoF (group 1 and 2) 4. Significant reduction in depression/anxiety (group 1) 5. Qualitative results
