    Eshkoor SA, Hamid TA, Nudin SS, Mun CY
    Med Devices (Auckl), 2014;7:225-30.
    PMID: 25018658 DOI: 10.2147/MDER.S63220
    BACKGROUND: Poor oral health, chronic diseases, functional decline, and low cognitive ability can increase the risk of falls in the elderly.
    OBJECTIVES: The current study aimed to show the effects of oral health, diabetes mellitus (DM), hypertension (HT), heart disease, functional status, and sociodemographic factors on the risk of falls in elderly with dementia.
    MATERIALS AND METHODS: The sample comprised 1,210 Malaysian elderly who were demented and noninstitutionalized. This study was a national cross-sectional survey entitled "Determinants of Health Status among Older Malaysians". The effects of age, ethnicity, sex differences, marital status, educational level, oral health, DM, HT, heart disease, and functional status on the risk of falls were evaluated. The multiple logistic regression model was used to estimate the effects of contributing variables on the risk of falls in samples.
    RESULTS: The prevalence of falls was approximately 17% in subjects. It was found that age (odds ratio [OR] 1.02), non-Malay ethnicity (OR 1.66), heart disease (OR 1.92), and functional decline (OR 1.58) significantly increased the risk of falls in respondents (P<0.05). Furthermore, having teeth (OR 0.59) and dentures (OR 0.66) significantly decreased the rate of falls (P<0.05).
    CONCLUSION: It was concluded that age, non-Malay ethnicity, functional decline, heart disease, and oral health significantly affected falls in dementia.

  2. Anticholinergic burden is associated with recurrent and injurious falls in older individuals
    Zia A, Kamaruzzaman S, Myint PK, Tan MP
    Maturitas, 2016 Feb;84:32-7.
    PMID: 26531071 DOI: 10.1016/j.maturitas.2015.10.009
    OBJECTIVE: While the anticholinergic activity of medications has been linked to cognitive decline, few studies have linked anticholinergic burden with falls in older people. We evaluated the relationship between anticholinergic burden and recurrent and injurious falls among community-dwelling older adults.
    STUDY DESIGN: This case-control study was performed on 428 participants aged ≥65 years, 263 cases with two or more falls or one injurious fall in the preceding 12 months, and 165 controls with no falls in the preceding 12 months. Anticholinergic burden was determined using the anticholinergic cognitive burden (ACB) scale. Upper and lower limb functional abilities were assessed with timed up and go (TUG), functional reach (FR) and grip strength (GS). Logistic regression analysis was employed to calculate the mediation effect of TUG, FR and GS on ACB associated falls.
    RESULTS: Univariate analysis revealed a significant association between an ACB score of ≥1 with falls (OR, 1.8; 95% CI; 1.1-3.0; p=0.01) and significantly poorer TUG and FR. The association between ACB≥1 and falls was no longer significant after adjustment for either TUG (OR for ACB associated falls, 1.4; 95% CI, 0.88-2.4; p=0.14) or FR (OR for ACB associated falls, 1.4; 95% CI, 0.89-2.4, p=0.12) but remained significant with GS.
    CONCLUSION: The association between recurrent and injurious falls and the use of any medications listed in the ACB scale was mediated through gait and balance impairment but not by muscular weakness, providing a novel insight into the potential mechanistic link between ACB and falls. Future studies should determine whether TUG and FR measurements could help inform risk to benefit decisions where ACB medications are being considered.

    PMID: 22408483 DOI: 10.3390/s91007849
    A novel on-axis general sun-tracking formula has been integrated in the algorithm of an open-loop sun-tracking system in order to track the sun accurately and cost effectively. Sun-tracking errors due to installation defects of the 25 m(2) prototype solar concentrator have been analyzed from recorded solar images with the use of a CCD camera. With the recorded data, misaligned angles from ideal azimuth-elevation axes have been determined and corrected by a straightforward changing of the parameters' values in the general formula of the tracking algorithm to improve the tracking accuracy to 2.99 mrad, which falls below the encoder resolution limit of 4.13 mrad.

  8. Fulltext Postural Control and Gait Performance in the Diabetic Peripheral Neuropathy: A Systematic Review
    Mustapa A, Justine M, Mohd Mustafah N, Jamil N, Manaf H
    Biomed Res Int, 2016;2016:9305025.
    PMID: 27525281
    Purpose. The aim of this paper is to review the published studies on the characteristics of impairments in the postural control and gait performance in diabetic peripheral neuropathy (DPN). Methods. A review was performed by obtaining publication of all papers reporting on the postural control and gait performance in DPN from Google Scholar, Ovid, SAGE, Springerlink, Science Direct (SD), EBSCO Discovery Service, and Web of Science databases. The keywords used for searching were "postural control," "balance," "gait performance," "diabetes mellitus," and "diabetic peripheral neuropathy." Results. Total of 4,337 studies were hit in the search. 1,524 studies were screened on their titles and citations. Then, 79 studies were screened on their abstract. Only 38 studies were eligible to be selected: 17 studies on postural control and 21 studies on the gait performance. Most previous researches were found to have strong evidence of postural control impairments and noticeable gait deficits in DPN. Deterioration of somatosensory, visual, and vestibular systems with the pathologic condition of diabetes on cognitive impairment causes further instability of postural and gait performance in DPN. Conclusions. Postural instability and gait imbalance in DPN may contribute to high risk of fall incidence, especially in the geriatric population. Thus, further works are crucial to highlight this fact in the hospital based and community adults.

  10. Randomized control trials on Otago exercise program (OEP) to reduce falls among elderly community dwellers in Shahroud, Iran
    Dadgari A, Aizan Hamid T, Hakim MN, Chaman R, Mousavi SA, Poh Hin L, et al.
    Iran Red Crescent Med J, 2016 May;18(5):e26340.
    PMID: 27478629 DOI: 10.5812/ircmj.26340
    BACKGROUND: Fall is a worldwide health problem among elderly people and a known leading cause of disabilities. Fall prevention programs have been implemented in various forms. The Otago exercise program (OEP) is one of the most recent home-base exercise training program.
    OBJECTIVES: This study was conducted to examine the effectiveness of OEP to reduce falls among elderly people in Shahroud, IR Iran.
    MATERIALS AND METHODS: This randomised control trial was conducted among the elderly community dwellers in Shahroud city of the Semnan province, IR Iran, with experience of falls in the last 12 months. Subjects of the study (n = 317) were recruited from elderly senior citizens at public health centers. Block systematic random sampling was applied to categorize the subjects in experimental and control groups. The experimental group (n = 160) received OEP for six months and was compared with the control group (n = 157) who received general health training. This study was registered with the following ID, IRCT2014012016285N1.
    RESULTS: The findings of the study showed that OEP improved physical performance (Berg-Balance-Score with P > 0.025, and Timed-Up-Go-Test with P > 0.017) and functional capacity (Arm-Curl-Test with P > 0.00 and Chair-Stand-Test with P > 0.01). In addition, OEP significantly reduced the incidence of falls (P ≤ 0.00) among senior citizens in the experimental group.
    DISCUSSION: The OEP as a home-based exercise is effective for the reduction of the incidence of falls among senior citizens with a history of falls. The OEP can be recommended for elderly homebound people who do not have access to facilities.

  11. The relationship between alcohol intake and falls hospitalization: Results from the EPIC-Norfolk
    Tan GJ, Tan MP, Luben RN, Wareham NJ, Khaw KT, Myint PK
    Geriatr Gerontol Int, 2021 Aug;21(8):657-663.
    PMID: 34156750 DOI: 10.1111/ggi.14219
    AIM: To evaluate the relationship between habitual alcohol consumption and the risk of falls hospitalization.

    METHODS: The EPIC-Norfolk is a prospective population-based cohort study in Norfolk, UK. In total, 25 637 community dwelling adults aged 40-79 years were recruited. Units of alcohol consumed per week were measured using a validated Food Frequency Questionnaire. The main outcome was the first hospital admission following a fall.

    RESULTS: Over a median follow-up period of 11.5 years (299 211 total person years), the cumulative incidence function (95% confidence interval) of hospitalized falls at 121-180 months for non-users, light (>0 to ≤7 units/week), moderate (>7 to ≤28 units/week) and heavy (>28 units/week) were 11.08 (9.94-12.35), 7.53 (7.02-8.08), 5.91 (5.29-6.59) and 8.20 (6.35-10.56), respectively. Moderate alcohol consumption was independently associated with a reduced risk of falls hospitalization after adjustment for most major confounders (hazard ratio = 0.88; 95% confidence interval 0.79-0.99). The relationship between light alcohol consumption and falls hospitalization was attenuated by gender differences. Alcohol intake higher than the recommended threshold of 28 units/week was associated with an increased risk of falls hospitalization (hazard ratio 1.40 [1.14-1.73]).

    CONCLUSIONS: Moderate alcohol consumption appears to be associated with a reduced risk of falls hospitalization, and intake above the recommended limit is associated with an increased risk. This provides incentive to limit alcohol consumption within the recommended range and has important implications for public health policies for aging populations.

  13. Fulltext Smartphone-based solutions for fall detection and prevention: challenges and open issues
    Habib MA, Mohktar MS, Kamaruzzaman SB, Lim KS, Pin TM, Ibrahim F
    Sensors (Basel), 2014 Apr 22;14(4):7181-208.
    PMID: 24759116 DOI: 10.3390/s140407181
    This paper presents a state-of-the-art survey of smartphone (SP)-based solutions for fall detection and prevention. Falls are considered as major health hazards for both the elderly and people with neurodegenerative diseases. To mitigate the adverse consequences of falling, a great deal of research has been conducted, mainly focused on two different approaches, namely, fall detection and fall prevention. Required hardware for both fall detection and prevention are also available in SPs. Consequently, researchers' interest in finding SP-based solutions has increased dramatically over recent years. To the best of our knowledge, there has been no published review on SP-based fall detection and prevention. Thus in this paper, we present the taxonomy for SP-based fall detection and prevention solutions and systematic comparisons of existing studies. We have also identified three challenges and three open issues for future research, after reviewing the existing articles. Our time series analysis demonstrates a trend towards the integration of external sensing units with SPs for improvement in usability of the systems.

  17. Test systems for the biomechanical evaluation of hip protectors: a systematic review
    Yahaya SA, Ripin ZM, Ridzwan MIZ
    Osteoporos Int, 2020 Jan;31(1):43-58.
    PMID: 31446442 DOI: 10.1007/s00198-019-05128-x
    Various mechanical and biomechanical test systems to evaluate the effectiveness of hip protectors designed to prevent hip fracture as a result of falls were examined in this review. The articles considered were selected systematically. The effect of differences in design criteria was demonstrated, and it was observed that the impact energy employed during testing dramatically affects the performance of the hip protector. Over the past three decades, researchers have continuously experimented with various systems to determine the efficacy of various hip protectors. The primary aim has been to make informed decisions in optimizing hip protector design. This article provides a systematic review of various test systems employed in the determination of the biomechanical efficacy of hip protectors. A systematic literature search was carried out, and 28 relevant articles were included to demonstrate the effect of test systems in the evaluation of the biomechanical effectiveness of hip protectors. Methodological studies illustrated the appropriate use of impact testing systems for the simulation of hip anatomy and fall dynamics in evaluating the effectiveness of hip protectors in preventing a hip fracture. This systematic review has demonstrated the effect of the variability of test systems on the evaluation of impact attenuation by various hip protectors. The lack of standardized test systems accounts for the inconsistencies in the test results of the efficacy of hip protectors. This has been a major challenge in the efforts of researchers to optimize the interventions. The standardization of test systems may require needed improvements immediately as opposed to the development of new interventions in order to ensure that only hip protectors with adequately proven efficacies are deployed for clinical trials or for the protection of the hips of vulnerable individuals from sideways impact.

  18. Fulltext Comparison of Retrospective and Prospective Falls Reporting Among Community-Dwelling Older People: Findings From Two Cohort Studies
    Romli MH, Mackenzie L, Tan PJ, Chiew RO, Tan SH, Tan MP
    Front Public Health, 2021;9:612663.
    PMID: 33777881 DOI: 10.3389/fpubh.2021.612663
    Background: While prospective recording is considered as the gold standard, retrospective recall is widely utilized for falls outcomes due to its convenience. This brings about the concern on the validity of falls reporting in Southeast Asian countries, as the reliability of falls recall has not previously been studied. This study aimed to evaluate the reliability of retrospective falls recall compared to prospective falls recording. Methods: A secondary analysis of data from two prospective recording methods, falls diary and falls calendar, from two different research projects were obtained and analyzed. Retrospective falls recall was collected either through phone interview or follow-up clinic by asking the participants if they had fallen in the past 12 months. Results: Two-hundred-sixty-eight and 280 elderly participated in the diary and calendar groups, respectively. Moderate (46%) and poor (11%) return rates were found on completed diary and calendar recording. Under-(32%) and overreporting (24%) of falls were found in diary compared to only 4% of overreporting for the calendar. Retrospective recall method achieved 57% response rate for the diary group (followed up at clinic) and 89% for the calendar group (followed up via telephone interview). Agreement between retrospective and prospective reporting was moderate for the diary (kappa =0.44; p < 0.001) and strong for the calendar (kappa = 0.89; p < 0.001). Conclusion: Retrospective recall is reliable and acceptable in an observation study within healthy community older adults, while the combination of retrospective and prospective falls recording is the best for an intervention study with frailer older population. Telephone interview is convenient, low cost, and yielded a high response rate.

  19. Fulltext Older Adults with Hypertension: Prevalence of Falls and Their Associated Factors
    Abu Bakar AA, Abdul Kadir A, Idris NS, Mohd Nawi SN
    Int J Environ Res Public Health, 2021 08 04;18(16).
    PMID: 34444005 DOI: 10.3390/ijerph18168257
    Falls are prominent health issues among older adults. Among hypertensive older adults, falls may have a detrimental effect on their health and wellbeing. The purpose of this study is to determine the prevalence of falls among hypertensive older adults and to identify the associated factors that contribute to their falls. This was a cross-sectional study conducted among two hundred and sixty-nine hypertensive older adults who were selected via systematic random sampling in two primary health clinics in Kuala Terengganu, Malaysia. Data on their socio-demographic details, their history of falls, medication history and clinical characteristics were collected. Balance and gait were assessed using the Performance Oriented Mobility Assessment (POMA). It was found that 32.2% of participants reported falls within a year. Polypharmacy (adjusted OR 2.513, 95% CI 1.339, 4.718) and diuretics (adjusted OR 2.803, 95% CI 1.418, 5.544) were associated with an increased risk of falls. Meanwhile, a higher POMA score (adjusted OR 0.940, 95% CI 0.886, 0.996) and the number of antihypertensives (adjusted OR 0.473, 95% CI 0.319, 0.700) were associated with a low incidence of falling among hypertensive older adults. Falls are common among hypertensive older adults. Older adults who are taking diuretics and have a polypharmacy treatment plan have a higher incidence of falls. However, older adults taking a higher number of anti-hypertensive medications specifically were not associated with an increased prevalence of falls.

  20. Fulltext Quantification of Gait Stability During Incline and Decline Walking: The Responses of Required Coefficient of Friction and Dynamic Postural Index
    Abdul Yamin NAA, Basaruddin KS, Abu Bakar S, Salleh AF, Mat Som MH, Yazid H, et al.
    J Healthc Eng, 2022;2022:7716821.
    PMID: 36275397 DOI: 10.1155/2022/7716821
    This study aims to investigate the gait stability response during incline and decline walking for various surface inclination angles in terms of the required coefficient of friction (RCOF), postural stability index (PSI), and center of pressure (COP)-center of mass (COM) distance. A customized platform with different surface inclinations (0°, 5°, 7.5°, and 10°) was designed. Twenty-three male volunteers participated by walking on an inclined platform for each inclination. The process was then repeated for declined platform as well. Qualysis motion capture system was used to capture and collect the trajectories motion of ten reflective markers that attached to the subjects before being exported to a visual three-dimensional (3D) software and executed in Matlab to obtain the RCOF, PSI, as well as dynamic PSI (DPSI) and COP-COM distance parameters. According to the result for incline walking, during initial contact, the RCOF was not affected to inclination. However, it was affected during peak ground reaction force (GRF) starting at 7.5° towards 10° for both walking conditions. The most affected PSI was found at anterior-posterior PSI (APSI) even as low as 5° inclination during both incline and decline walking. On the other hand, DPSI was not affected during both walking conditions. Furthermore, COP-COM distance was most affected during decline walking in anterior-posterior direction. The findings of this research indicate that in order to decrease the risk of falling and manage the inclination demand, a suitable walking strategy and improved safety measures should be applied during slope walking, particularly for decline and anterior-posterior orientations. This study also provides additional understanding on the best incline walking technique for secure and practical incline locomotion.
