Incidence and factors associated with falls in independent ambulatory individuals with spinal cord injury: a 6-month prospective study.

Background Sensorimotor impairments following spinal cord injury (SCI) affect mobility and subsequently increase the risk of falls to patients. However, most of the fall data for these patients were retrospectively gathered. Objectives This study prospectively assessed falls and intrinsic factors associated with falls in 89 independent ambulatory individuals with SCI over the course of 6 months. In addition, functional ability between participants who did and did not fall was compared. Methods Participants were interviewed and assessed for their baseline data and functional ability using the Timed “Up & Go” Test and the Six-Minute Walk Test. Then they were interviewed by telephone to complete a self-report questionnaire once per week to gather fall data for 6 months. A stepwise multiple logistic regression was utilized to determine the effects of demographics and SCI characteristics on occurrence of falls. The functional data between participants who fell and those who did not fall were compared using the Mann-Whitney U test. Results Thirty-five participants (39%) experienced at least 1 fall during 6 months (range=1–11). Two participants required medical attention due to patellar and sternum fractures after falling. Participants with an educational level of high school graduate or greater, an American Spinal Injury Association Impairment Scale C (AIS-C) classification, and a fear of falling (FOF) significantly increased their risk of falls approximately 4 times more than those who graduated primary education, had an AIS-D classification, and did not have FOF. Moreover, the functional abilities of participants who fell were significantly poorer than those who did not fall. Limitations The sample size was calculated based on the primary objective (incidence of falls), which may not be sufficient to clearly indicate factors associated with falls for the participants. Conclusions More than one third of the independent ambulatory participants with SCI experienced at least 1 fall during the 6-month period of the study. The findings suggest the importance of functional improvement on the reduction of fall risk in these individuals.

Reference Values of Physical Performance in Thai Elderly People Who Are Functioning Well and Dwelling in the Community

Background Because the number of elderly people is rapidly increasing, reference values for the physical abilities necessary to independently conduct daily activities are crucial for promoting good health. Although a few studies have reported reference values for functional tests relating to these abilities, all of those values were derived from populations in developed countries, which have baseline demographic and anthropometric characteristics different from those of Thai people. Objective The purpose of this study was to describe reference values for 5 physical performance tests for Thai elderly people who were functioning well and dwelling in the community. Design A cross-sectional design was used in this study. Methods A total of 1,030 Thai elderly people who were functioning well were cross-sectionally assessed for their physical abilities with 5 functional tests: 10-Meter Walk Test, Berg Balance Scale, Timed “Up & Go” Test, Five Times Sit-to-Stand Test, and Six-Minute Walk Test. The data were reported with descriptive statistics according to decade of age and sex. Differences among the age decades and between the sexes were analyzed with a 1-way analysis of variance and an independent-sample t test, respectively. Multiple linear regression analyses were used to determine baseline characteristics important in functional abilities. Results Most of the values found for the performance-based measures were lower than those previously reported, with a significant trend toward age- and sex-related functional decline. Weight and height were important contributors to level of functional ability. Limitations Only a few elderly individuals older than 90 years of age participated in this study. Therefore, their findings were combined with those of participants aged 80 to 89 years. Conclusions The findings described here may be useful as reference values for 5 physical performance tests for Thai elderly people. Health practitioners can use this information to identify functional impairments early and to promote independence in Thai and other elderly populations with similar anthropometric characteristics, such as those in the Association of South East Asian Nations.

Factors associated with knowledge and attitudes in persons with epilepsy

Treating persons with epilepsy (PWE) in developing countries may be different from elsewhere. Knowledge and attitudes of PWE are known to be associated with seizure control. This study aims to evaluate factors related with the knowledge and attitudes of PWE in northeastern Thailand. A cross-sectional survey using questionnaires and interviews was undertaken at the Khon Kaen University epilepsy clinic. The questionnaire comprised 22 questions (14 knowledge questions and 8 attitude questions). Two hundred three PWE participated in the study with a mean age of 36.5 years. Four factors were significantly associated with the knowledge about epilepsy, which included education level, age, epilepsy duration, and a history of experiencing antiepileptic medication side effects. In addition, there were four factors significantly associated with the attitudes about epilepsy, which included seizure control, education level, epilepsy duration, and marital status. There is a need to provide more education, preferably community based, to help PWE obtain more accurate information.

Discriminative ability of the three functional tests in independent ambulatory patients with spinal cord injury who walked with and without ambulatory assistive devices

Abstract Background/objectives Many persons with spinal cord injury (SCI) require an ambulatory assistive device (AAD). An effective monitoring method enables the use of an appropriate AAD and promotes levels of independence for patients. This study investigated the discriminative ability of the three-functional tools relating to walking ability, including the 10-meter walk test (10MWT), the five times sit-to-stand test (FTSST), and the timed up and go test (TUGT), in independent ambulatory persons with SCI who walked with walker, crutches, cane, and non-AAD. Methods Eighty-five persons with SCI who could perform sit-to-stand and walk independently at least 50 m were cross-sectionally assessed for their functional ability using the 10MWT, FTSST, and TUGT. Results The findings for persons not using AADs were significantly better than the other groups for every test (P < 0.001). In addition, persons who walked with cane were significantly different from those who used walkers (P < 0.001) but there were no significant differences between persons who used walker and crutches for every test (P > 0.05). Conclusion The findings supported the discriminative validity of the tools, allowing them to indicate functional changes in persons with SCI who walk with different AADs. However, the non-significant differences between subjects who used a walker and crutches may relate to the method of subject arrangement and inclusion criteria that recruit subjects with rather good walking capability and lower limb function. The findings may also suggest the use of the sit-to-stand maneuver as a simple screening tool for walking advancement of walker users, pending further investigation.

Medical complications and falls in patients with spinal cord injury during the immediate phase after completing a rehabilitation program

Abstract Background/objectives Complications and falls are crucial problems in patients with spinal cord injury (SCI). However, existing evidence on complications comes from data from hospital records over a long period of time, and falls were mostly reported retrospectively in patients with incomplete SCI. This study prospectively explored the occurrence of complications and falls, and associated factors in patients with SCI during the 6 months after discharge. Methods One hundred subjects with SCI (50 wheelchair-bound (WB) and 50 ambulatory (AM) subjects) from a tertiary rehabilitation center completed the study. Every month, subjects were monitored for data on medical complications and falls. Descriptive information is provided for each group. Results Every WB subject had complications and 14 subjects were re-hospitalized. The most frequent complications found in these subjects were neurogenic pain (36 subjects), urinary tract infection (UTI) (25 subjects), and pressure ulcers (21 subjects). In AM subjects, 38 subjects (76%) experienced complications and 3 subjects needed re-hospitalization. The most frequent complications included neurogenic pain (35 subjects) and UTI (11 subjects). Eighteen WB subjects (36%) and 27 AM subjects (54%) experienced falls. WB subjects had significantly increased odds for incidence of UTI and pressure ulcers, whereas AM subjects had significantly greater odds for falls (P < 0.05). Conclusion A number of subjects with SCI experienced complications and falls after completing a rehabilitation program. The findings add to our knowledge about complications and falls after SCI, and confirm the importance of effective strategies to minimize the occurrence of complications and falls in these individuals.

Functional assessments for predicting a risk of multiple falls in independent ambulatory patients with spinal cord injury.

Abstract Background/objectives Many ambulatory patients with spinal cord injury (SCI) encountered multiple falls and serious consequences after falls, but there was no quantitative practical measure for early identification of individuals at a risk of multiple falls. This study compared the utility of the Berg Balance Scale, Timed “Up & Go” Test, 10-Meter Walk Test, Functional Reach Test (FRT), Step Test, and Five Times Sit-to-Stand Test to predict risk of multiple falls (fall ≥2 times) in these individuals. Methods Eighty-three independent ambulatory subjects with SCI were assessed for their functional abilities using the six tests. Then, their fall data were monitored prospectively every 2 weeks for 6 months in total. The first 25 subjects were also involved in the reliability tests. Results The FRT showed the best predictive ability for the risk of multiple falls (cut-off score ≥20 cm, sensitivity = 73%, specificity = 55%, area under the receiver characteristic curve = 0.64, and adjusted odd ratio = 3.18, P < 0.05), excellent inter-tester reliability, and good feasibility. Conclusions The FRT may be used as a screening tool to predict risk of multiple falls in independent ambulatory individuals with SCI. However, with a moderate level of specificity, a further comprehensive test may be needed to clearly indicate individuals at a risk of falls. In addition, the findings suggest that a higher level of ability increases the risk of multiple falls. Thus, programs for functional integration in an actual environment may be needed to reduce the risk of falls for these individuals.

Knowledge, attitudes, and care techniques of caregivers of PWE in northeastern Thailand

Caregivers of persons with epilepsy (PWEs) in developing countries do not always have access to correct information related to the affliction of the patients they are entrusted to care for. Epilepsy can be difficult to manage for all those involved, whether it is a family member, the PWEs themselves, or the caregiver. Misconceptions are common about epilepsy, especially in undeveloped countries where a majority of the population have lower educational levels. This study aims to acquire baseline data about caregivers of PWEs related to their knowledge, attitudes, and methods of giving care to PWEs. A cross-sectional survey was administered to 83 PWE caregivers at a university epilepsy clinic in northeastern Thailand. The caregivers believed that knowledge about epilepsy was paramount; however, they felt that their own knowledge of the condition was insufficient. Educational level, relationship to the PWEs, and sex were correlated to various aspects related to epilepsy knowledge and attitudes in caregivers. A slight negative correlation was found between caregiver knowledge and attitudes toward epilepsy with Pearsons correlation coefficient (r=-0.38, P-value 0.001). Education and improved epilepsy information need to be provided to the caregivers of PWEs in northeastern Thailand.

The relationships between the use of self-regulated learning strategies and depression among medical students: an accelerated prospective cohort study.

We conducted this study to determine the relationships between the use of self-regulated learning strategies (SRL) and depression scores among medical students. An accelerated prospective cohort study among 623 students at a public medical university in Vietnam was carried out during the academic year 2012–2013. The Depression, Anxiety and Stress Scales (21 items) was used to measure depression scores as the primary research outcome, and to measure anxiety and stress scores as the confounding variables. Fourteen SRL subscales including intrinsic/extrinsic goal orientation, task value, self-efficacy for learning, control of learning beliefs, rehearsal, elaboration, organization, critical thinking, meta-cognitive strategies, time and study environment, effort regulation, peer learning, and help seeking were measured using the Motivated Strategies for Learning Questionnaire. Data were collected at two points in time (once each semester). There were 744 responses at the first time (95.88%) and 623 at time two (drop-out rate of 16.26%). The generalized estimating equation was applied to identify any relationships between the use of each SRL subscale and depression scores at time 2, adjusting for the effects of depression at time 1, anxiety, stress, within cluster correlation, and potential demographic covariates. Separate multivariate GEE analysis indicated that all SRL subscales were significantly negatively associated with depression scores, except for extrinsic goal orientation and peer learning. Whereas full multivariate GEE analysis revealed that self-efficacyT1, help-seekingT1, time and study environmentT2 were found to be significantly negatively associated with depressionT2, adjusting for the effects of depressionT1, anxiety, stress, and demographic covariates. The results should be used to provide appropriate support for medical students to reduce depression.

Diet, exercise, sleep, sexual activity, and perceived stress in people with epilepsy in NE Thailand

The aim of this study was to find out how people with epilepsy in NE Thailand feel about their levels of stress, sleep, diet, exercise habits, and sex lives using a cross-sectional design. Two hundred and three people with epilepsy (PWE) were randomly recruited from a university epilepsy clinic in Khon Kaen and then completed an interview and a questionnaire. A total of 27.6% of the patients believed that diet had an influence on their epilepsy (of those who reported changes, 41.1% stopped consuming alcohol, while 32.1% stopped drinking caffeinated beverages). A total of 47.2% of the patients exercised at least three times per week, while 52.8% exercised two times or less a week. Daytime sleeping was prevalent, with 43.3% saying that they slept during the day frequently or every day. There were 44.3% of the patients who believed that their sex lives changed after the onset of epilepsy, with decreased sexual arousal being most commonly mentioned. A total of 76.4% of the patients said that they had medium or high levels of stress, and epilepsy was listed as the most common reason for their stress (50.2%). Focusing on the problem was the most common method to reduce stress (80.3%). The findings illuminate the need to increase attention towards improving and promoting self-management of epilepsy. As a whole, diet, exercise, sleep, stress reduction, and sex therapy can be valuable tools to improve the quality of life of people with epilepsy.

Predictive risk factors of seizure-related injury in persons with epilepsy

OBJECTIVE The clinical risk factors for seizure-related injuries (SRI) in adult persons with epilepsy (PWE) were studied and analyzed to develop a predictive model. METHODS We enrolled 300 consecutive cases from three epilepsy clinics in Northeast, Thailand. Subjects were eligible if reported to have at least one seizure attack during the past 12 months. Face-to-face questionnaire was used to evaluate SRI, baseline characteristics and other seizure-related variables. RESULTS There were 247 and 91 PWE who met a criterion and had SRI, respectively. By multivariate logistic regression method, GTC seizure type, having history of seizure attacks at least 12 times/year, and daytime seizure were significant risk factors of having SRI with odds ratio of 2.376, 2.460, and 3.562, respectively. We developed the predictive model for having SRI in PWE and it gave 90.3% sensitivity and 46.7% specificity on the occurrence of SRI. The estimated probability of SRI can be found online at http://sribykku.webs.com/. CONCLUSIONS The significant predictive factors for SRI in PWE were the occurrence of GTCs, seizures at least 12 times/year or daytime seizures. Clinicians or PWE can easily evaluate the risk of having SRI in individuals by the online predictive model.
