Fall in Elderly

1 The Role of Siamese qi Exercise in Promoting Health Benefits for Older Persons Fuzhong Li, Ph. D. , operating theatre Research land Thai chi, or Thaijiquan to be exact, originated in kina or so 300 hundreds years agone ( khina Sports, 1980) and began as a form of martial arts like boxing. It has go on to evolve from being originally apply as a combative and self-defense form to a wellness-enhancing lick, practiced by individuals of all ages to keep an eye on health and pr up to nowt distemper.As an alternative cipher, Thai khi has move increasing seek interest, with accumulating bear witness intending the therapeutic value of siamese connection chi to overall health and well-being. The goal of this paper is to summarize rate of f junior-grade research findings with a particular focus on geriatric populations, handle findings with respect to their practical implications, and high silly future research chargeions.Overview of Research Findings A number of excellent review articles exist showing evidence that Siamese khi generates various health benefits for individuals of varying age groups and patient populations (Fasko & Grueninger, 2001 Lan, Lai, & Chen, 2002 Li, Hong, & Chan, 2001 Verhagen, Immink, va der Meulen et al. , 2004 Wang, Collet, & Lau, 2004 Wayne, Krebs, Wolf, et al. , 2004 Wu, 2002). Without delinquent redundancy, the avocation provides a summary review of research studies that involve randomised main Thainled trials (RCTs) although results from non-RCTs argon account in the absence of RCTs.With aging processes, declines in sensible and mental status in sure-enough(a) adults often result in respite consider impairments, functional limitations in locomotor activities, disability in particular activities, and decreased quality of deportment. Therefore, this review besides focuses on health outcomes that hurt been shown to be clinically most relevant to this population. These include remnant and locomote , musculo impecunious conditions, intermission quality, cardiovascular and respiratory function, and psychosocial wellbeing.Balance Control, go, and Fear of locomote Falls argon pregnant common health problem among old adults (Murphy, 2000 Stevens, 2005), making it a major threat to the independence and quality of life of old(a) adults, as well as imposing momentous effect to individuals, society, and national health systems (National activity Plan, 2005). As a stand-alone crop intervention, Siamese chi has been shown to reduce the risk for string up. Wolf and his colleagues (1996) conducted the very first of all randomized controlled trial comparing the efficacy of two methods of dress on move.Community living healthy adults were randomized to one of collar groups siamese connection chi prep computerized correspondence homework and an attention control. Results of this 15-week trial showed that siamese connection khi role players experienced signifi senst reductions (by about 47%) in square ups comp atomic number 18d to the recitation control participants. In a follow-up 48-week RCT, Wolf et al (2003) evaluated Siamese khi with quondam(a) adults who were less robust (that is, transitioning to feebleness). No significant amongst-experimental group reductions in locomote were spy.However, by analyzing fall data from month four through month twelve, the study showed a significantly reduce risk of falls in the siamese connection chi group comp atomic number 18d with the usance control group. In an independent study, Li et al. (2005) confirmed the general findings of those report by Wolf and his colleagues. These researchers describe that, at the end of a 6-month Siamese chi intervention, significantly fewer falls (38 versus 73), lower proportions of fallers (28% versus 46%), and perverting falls (7% versus 18%) were sight in the Thai ki condition, comp ard to a low-impact reaching control condition. Overall, the risk of multiple falls in the Tai Chi group was 55% lower than that of the stretching controls. In addition, comp bed to stretching control participants, Tai Chi participants showed significant purifyments in measures of functional eternal sleep, corporeal performance, and cut fear of fall. Of equal importance, intervention gains in these measures were maintained at a 6-month postintervention follow-up in the Tai Chi group (Li et al. 2004). musculoskeletal Conditions Evidence to hear forecasts that Tai Chi training preserves or even increases lower-extremity muscle force play. Wolfson et al. (1996) showed that 6 months of Tai Chi training (following their basal interventions) did non improve lower-extremity muscle strength, compared to an operation control group. However, their data did indicate that Tai Chi training preserved lowerextremity strength gains developed by the intervention. In a 20-week pilot study, Christou et al. 2003) showed that, compared to those in the con trol condition, Tai Chi participants significantly improved knee joint extensor strength and force control among of age(p) adults. Tai Chi also appears to be safe and scarce for patients with rheumatoid arthritis. In a randomized trial among old women with degenerative arthritis, metrical composition et al (2003) showed a 12-week Tai Chi program resulted in significant improvements in pain and stiffness in joints, equilibrate, and abdominal strength, and fewer reported perceived difficulties in corporeal functioning, compared to those of control subjects.Another randomized trial, Hartman et al (2000) showed that a 12week program significantly improved osteoarthritis symptoms such(prenominal) as fatigue, arthritis selfefficacy, feelings of tension, and satisfaction with general health status. to a greater extent recent evidence points to the likely of Tai Chi as a weight-bearing cipher for agreeing rig out leaving in former(a) women. In a 12-month randomized trial, Cha n et al (2004) well-tried the hypothesis that Tai Chi whitethorn retard bone loss in early postmenopausal women.At the end of the trial, bone mineral density (BMD) measurements revealed a general bone loss in twain Tai Chi and control subjects at all measured skeletal sites, but with a slower rate in the Tai Chi group. Although the BMD findings were equivocal, the findings lend approximately support for the potential of Tai Chi to retard bone loss. Cardiovascular and Respiratory Function Although legion(predicate) studies comport evaluated the cause of Tai Chi on cardiovascular and respiratory function, no RCTs have been reported that involve older adults.A number of Taiwanbased observational studies have shown improvements in cardiorespiratory function resulting from Tai Chi. For example, among long-term older adults practicing Tai Chi, significantly wear cardiorespiratory function has been reported (Lai, Lan, Wong, & Teng, 1995 Lan, Lai, Chen, & Wong, 1998), and improveme nts were also observed among coronary arteria bypass surgery patients deemed to be at low risk during their participation in a Tai Chi exercise program (Lan, Chen, Lai, & Wong, 1999). Hypertension Tai Chi is a low-impact activity with self- footstepd and bland causas, making it appropriate as a delegacy to reduce downslope pressure in stack with hypertension. Two intervention trials compared the effectuate of Tai Chi and aerophilous exercise on blood pressure a surrogate for hypertension. An anterior study by Channer et al (1996) showed that over 11 sessions of exercise, both Tai Chi and aerobic exercise were associated with reductions in systolic blood pressure Tai Chi was also associated with reductions in diastolic blood pressure in a sample of patients re lotion from ague myocardial infraction.In a different study by new-fashioned et al. (1999), sensiblely in quick older women with systolic blood pressure 130-159 mmHg and diastolic blood pressure 95 mmHg were random ized to a 12-week moderate-intensity aerobic exercise program or a Tai Chi program of light activity. At the end of the intervention, the Tai Chi group decreased 7. 0 mmHg of systolic and 2. 4 mmHg of diastolic blood pressure. No significant differences were observed between the two exercise activities.The authored concluded that programs of moderate intensity aerobic exercise and light exercise whitethorn have similar effects on blood pressure in previously sedentary older individuals. Quality of Sleep Self-reported calmness complaints are common among older adults (Neubauer, 1999) and it is estimated that up to 50% of ripened nighbodys complain about their sleep (Alessi, 2000). Li et al. (2003) conducted a six-month intervention trial to examine the impact of a simpler Tai Chi program on better quality of sleep and reducing twenty-four hour period sleepiness among older adults reporting moderate sleep complaints.Participants were randomly assign to a Tai Chi group or an exer cise control group. At the end of the study, Tai Chi participants reported significant improvements in several sleep-quality related measures in comparison to the control participants with reduced sleep latency (by about 18 minutes per night) and daytime sleepiness, and improved sleep duration (by about 48 minutes per night). The study provided preliminary evidence linking the benefits of Tai Chi exercise to improved quality of sleep and reduced daytime sleepiness in older adults.Psychosocial Wellbeing and Confidence Li and his colleagues (2001a,b,c,d, 2002a, 2002b) provided a series of reports examining the extent to which Tai Chi enhanced older adults multidimensional mental well-being and health-related quality of life indicators. In a 6-month randomized controlled trial, healthy older adults were randomly assigned to either a control condition or Tai Chi. Results indicated that Tai Chi participants reported higher levels of health perceptions, life satisfaction, positive affect , and well-being, and lower levels of depression, negative affect, and mental distress (Li et al. 2001a). Participants also showed higher levels of both domain- particularized physical conceit (Li et al. , 2002b) and exercise self-efficacy relevant to movement confidence (Li et al. , 2001c). Change in the level of movement self-efficacy was found to be significantly related to change in physical functioning (Li et al. , 2001b). Similar profiles have been reported by other researchers (Kutner, Barnhart, Wolf, McNeely, & Xu 1997) in that Tai Chi practice resulted in improved well-being, increased alertness, relaxation, break up mental outlook, achievement, and great confidence. Practical Implications The previous summary and review organizes it separate that Tai Chi provides multiple health and therapeutic benefits for older adults. Thus, some discussion of practical implications appears to be in order. Fall Prevention Falls can result in devastating consequences for older adult s. Accumulating evidence to date suggest that Tai Chi may be an good means of improving deficits in balance and functional limitations, and therefore, may serve as a therapeutic exercise for balance and strength, and consequently, reduce the risk of falling and the rate of falls in older adults.Tai Chi may also be considered as an exercise modality that generates confidence building to counteract fear of falling, a common psychological symptom of falls among participation adults. However, Tai Chi does not provide a degraded fix for the fall problem. Most research in this area has cerebrate on short-term results. Findings from current RCTs show that, however, a minimum of three months training is regardd before clinically meaningful reductions in risks of falling can be achieved, suggesting the invite for long-term, makeed, and frequent practice, perhaps on a day-to-day basis, to obtain the full benefit.Tai Chi as an Alternative, alterative Exercise Tai Chi has been recommen ded for treating many chronic conditions. For example, as a lowimpact, low-intensity alternative exercise therapy, Tai Chi has also been proposed as a potential option for the management of osteoarthritis (Lumsden, Baccala & Aartire, 1998). As a fall legal profession activity, Tai Chi has emerged as an appropriate stand-alone balance training program for older adults to improve balance and prevent falls (JAGS, 2001).But even though Tai Chi appears to have numerous benefits to participants, it is still too early for physicians to begin prescribing Tai Chi as a remedy for chronic health problems because many of the studies have determination limitations (Wang et al. , 2004), making it difficult to generalize results to broader patient populations. In this regard, patients with chronic health problems need to take precautions before beginning a Tai Chi program, because for some people Tai Chi could worsen medical conditions or problems/ symptoms. In some cases, appropriate odificatio ns may be inevitable to better accommodate patients special needs or physical limitations. Program Costs, Logistics, and Protocols one of the most desirable aspects of Tai Chi is its absence of a need for high technology in promoting health. Tai Chi is easily tell from highly technical computerized balance training protocols, and may be just as successful in achieving fall reduction or balance improvement objectives certainly, Tai Chi is more practical. Tai Chi is a low-cost exercise regimen because special equipment or facilities are not needful (Lan et al. 2002 Li et al. , 2003). Li et al (2001b) reported that, in a 6-month RCT, the total direct cost was approximately $9000 (an average of $3. 50 per person per session). Others (Wilson & Datta, 2001) have reported that a twice weekly Tai Chi program was cost-saving whether direct benefits alone (hip fracture costs averted) or direct plus indirect benefits were considered, with a total net cost savings of $1274. 43 per person pe r year. When considering direct cots only, the net cost savings were $8. 04 per participant per year.Lower costs ensure that more community-dwelling older adults have 5 sufficient access to programs, and abundant opportunities to participate, which is likely to have profound public health implications. While costs of learning Tai Chi are potentially low, one should not underestimate the fact that Tai Chi is a complex system of movements that, when performed, requires body awareness, motor coordination, and agility features that could make Tai Chi less immediately deliverable to community adults (Li et al. 2003). Therefore, even though the benefits of regular Tai Chi exercise are quite an clear, the challenge of maximizing the opportunity for older persons remains because certain movements may be beyond the capabilities of some antiquated individuals or others with disabilities. Thus, there is a need to modify existing Tai Chi protocols to develop forms that are simple, easy to per form, and enjoyable (Chen, 2002 Li et al. , 2003 Wolf et al. , 1997), and that do not require years of sustained practice to master.Tai Chi Styles There are several sprints of Tai Chi, some of which are historic/traditional and some of which are of more recent origin. The earliest known form can be traced to the Chen style and evolved and progressed into multiple styles or schools. Currently, there are five main schools of Tai Chi ( tidy sums Sports, 1996), each named subsequently the styles founding family (a) Chen, (b) Yang, (c) Sun, (d) Wu (Jian Qian), and (e) Wu (He Qin).Each style has a distinctive protocol that differs from other styles in the postures or forms included, the order in which they appear, the pace at which movements are executed, and the level of difficulty. For example, one significant difference between Chen and Yang styles is that Yang style movements are relaxed and evenly paced. By comparison, the Chen style is characterized by alternating slow movements with quick and vigorous movements, including restrained and controlled actions/motions, reflecting its martial origin.Yang Style Tai Chi, which evolved from the Chen school, is probably the most popular Tai Chi style being practiced today (e. g. , Swaim, 1999 Yu & Johnson, 1999). Yang style movements are performed in a relaxed and flowing manner, with the trunk erect as the axis of rotation of all movements, making it immediately suitable for elderly, frail, or disabled populations. To date, the Yang style, with its variations, has been used as an therapeutic exercise modality in most medical and behavioral research.Although there are multiple versions of the Yang style (both short and long, covering 24-, 48-, 88-, and 108-Forms) ( chinaware National Sports Commission, 1983), the 24-Form, based on the most popular sequences of the Yang Chengfu school (China Sports, 1980 pack Sports, 1996), is the most quick adaptable to the life-styles and living situations of older adult populat ions. It is also the most accommodating, requiring minimal demands of personal strength, speed, endurance, flexibility, and motor skills for participation. Is Tai Chi arrange for Dissemination?In a 2001 joint communique on the bar of falls among the elderly, the American Geriatrics Society, the British Geriatrics Society, and the American academy of Orthopedic Surgeons suggested that Tai Chi is a promising type of exercise, although it requires provided evaluation before it can be recommended as the preferred balance training (JAGS, 2001). Since the publication of this joint communique, one large successful RCTs has been published (Li et al. , 2005) providing supporting evidence documented by Wolf et al. s earlier work (1996).As a result of these studies, we should be asking questions about how we can most effectively translate and disseminate the Tai Chi program. With this accumulated evidence, the time is near 6 for Tai Chi to be recommended as a preferred exercise for balan ce training and be routinely prescribed for older patients at risk for falling following appropriate screening. Future Research Directions Despite the increasing interest in studying the effectiveness of Tai Chi training and the resulting evidence of health benefits, there remain areas that require further research.We highlight a few of these. A get hold of to Understand the Mechanisms of the Benefits Shown Although findings from Tai Chi intervention studies are grand from a public health perspective, they provide minuscule development relative to the underlying mechanisms that may make grow such effects. In this regard, little attention has been given considering intervention/ interference mediators or moderators that help send causal pathways between treatment and outcome, and possible mechanisms through which a treatment might achieve its effects.For example, although Tai Chi has repeatedly been shown to improve balance, possible mechanisms by which Tai Chi improves this o utcome, and prevent subsequent falls, remains to be determined. Future studies should target specifically older adults with balance impairments, and consider incorporate laboratory and/or clinical measures that may help identify specific mechanisms whereby Tai Chi can remedy balance disorders. A Need to Better Understand Effects to Patients with Chronic Conditions A review by Wang et al. (2004) concluded that there is insufficient information to recommend Tai Chi to patients with chronic conditions.For example, the impact of Tai Chi on several important geriatric syndromes such as frailty, dementia, and sarcopenia are worthy of study or further research. Large clinical trials, involving populations with specific medical conditions are needed before health professionals can recommend Tai Chi exercise as an alternative to the more conventional exercise forms that have been shown to produce health benefits. The potential application of Tai Chi to important geriatric issues yet to be s tudied include obesity, osteoporosis, diabetes, neurological disorders (e. g. , Parkinsons disease peripheral neuropathy).A Need to Study Long-Term Effects Tai Chi intervention studies are typically conducted with a short-duration (e. g. , 3 months, 6 months). Long-term effects of Tai Chi training (e. g. , 12 months up to 2 or 3 years) are largely undetermined. Therefore, questions such as how long the established effects on clinical endpoints will sustain over a longer period of time remains to be determined. Certain outcomes may take a longer time to show an effect. Reductions in falls are a good example. Other outcomes such as BMD, may require up to one year to make clinically meaningful change because Tai Chi is a low-impact activity.Also, research from the general exercise literature indicates that people who participate in an exercise program often fall back into their older inactive lifestyle after a program ends (van der Bij, Laurant, & Wensing, 2002). Although anecdotal e vidence suggest that participants remained active upon program termination (Li et al. , 2001b Wolf et al. , 1996), critical issues such as get people to initiate and maintain the Tai Chi activity over a long-term need to be addressed. A Need to pass judgment Programs That Can Be Disseminated in Broader Community Settings Ultimately, for the results of the research-based evidence to have greater public health impact they must be diffused and do accessible to the community. However, it remains unclear whether the general community can readily implement or adopt these Tai Chi training protocols despite evidence of their tested efficacy. To date, there is no widespread, nationally available Tai Chi-based falls prevention program that is based on the effectiveness of scientifically controlled studies. In this regard, program evaluation research is needed to translate effective interventions into a program that is implementable in community settings.The Oregon Research Institute is cu rrently conducting a switch to move effective interventions into community practice. The project has identified randomized controlled studies of scientifically-based effective Tai Chi fall interventions and focuses on issues related to reach (i. e. , proportion of older adults who are willing to participate in a given Tai Chi program initiative), inlet (adoption i. e. , the proportion of settings and service agencies who are willing to initiate a program), and execution of instrument (i. e. the intervention agents fidelity to the various elements of a Tai Chi training protocol, including consistency of delivery as think and the time and cost of the intervention). The intended results of this translation and dissemination project will provide an effective, evidence-based falls prevention package that can be implemented in community settings to improve functional ability and reduce fall prevalence among community-dwelling older adults. thick The extant research evidence provides strong support for what was originally considered anecdotal evidence about the health benefits of Tai Chi for older adults.Overall, Tai Chi has been shown to have physiologic and psychosocial benefits and appears to be safe and effective in promoting balance control and muscular strength, and cardiovascular fitness for older adults. More research is needed, with rigorous scientific methodologies, to fully understand the mechanisms whereby Tai Chi produces these health benefits. From a public health perspective, immediate efforts are needed to translate programs that can be disseminated in local settings that target community healthy older adults. Fuzhong Li, Ph.
