The first metatarsophalangeal joint bending plays an important role in the foot movement. However, the existing researches mainly focused on the movement scope of the joint and the clinical treatments of related foot diseases. In order to investigate the effects of the first metatarsophalangeal joint bending on human walking gait stability, the present researchers recruited 6 healthy young men to perform the first metatarsophalangeal joint constraint (FM-JC) and barefoot (BF) walking tests. Data of the temporal and spatial parameters, the joint angles of lower limbs, the ground reaction forces (GRF) and utilized coefficients of friction (UCOF) were collected and analyzed. The results showed that, since hip and knee could produce compensation motions, the FMJC had no significant effects on waking gait, but the slip and fall probability increased significantly.
Objective To retrieve and summarize the best evidence for fall prevention after total hip arthroplasty in elderly patients. Methods BMJ Best Practice, UpToDate, JBI evidence-based healthcare center database, National Institute for Health and Clinical Excellence, Scottish Intercollegiate Guidelines Network, Cochrane Library, PubMed, Web of Science, EBSCO, International Collaboration of Orthopaedic Nurisng website, American Academy of Orthopaedic Surgeons website, European Society for Trauma and Emergency Surgery website, Medlive, China National Knowledge Infrastructure, Wanfang, Chongqing VIP, and SinoMed were systematically searched. The retrieval time was from the establishment of the databases to June 30, 2024. The quality of literature was evaluated, and evidence was extracted, evaluated, and summarized. Results A total of 12 articles were included, including 4 guidelines, 2 randomized controlled trials, 2 cohort studies, and 4 expert consensus studies. A total of 18 pieces of evidence were extracted, including 13 A-level recommendations and 5 B-level recommendations. The evidence covers six major themes of risk factors, assessment, multidisciplinary team support, health education, medication management, safety environment, and assistive devices. Conclusions The fall prevention after total hip arthroplasty in elderly patients involves multiple factors, and the fall prevention should be based on multidisciplinary team cooperation, achieving linkage between the hospital and the family to jointly ensure patient safety. In the future, it is recommended to combine individual patient differences with actual clinical scenarios when applying evidence.
ObjectivesTo systematically evaluate the impact of Tai Chi on the fall and balance function of middle-aged and the elderly.MethodsPubMed, EMbase, Web of Science, The Cochrane Library, CNKI and WanFang Data databases were electronically searched to collect randomized controlled trials (RCTs) on the influence of Tai Chi on the balance function and fall of middle-aged and the elderly from inception to August, 2019. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Meta-analysis was then performed by RevMan 5.3 software.ResultsA total of 20 RCTs involving 3 842 patients were included. The results of meta-analysis showed that the Tai Chi group was superior to the control group in the improvement of the fall rate (RR=0.82, 95%CI 0.75 to 0.90, P<0.000 01), single-leg standing test (MD=5.76, 95%CI 0.62 to 10.90, P=0.03), Berg balance scale (MD=1.04, 95%CI 0.23 to 1.85, P=0.01), timed up and go (MD=−0.71, 95%CI −0.88 to −0.54, P<0.000 01), chair stand test (MD=0.87, 95%CI 0.05 to 1.70, P=0.04) and other indicators, and the difference was statistically significant.ConclusionsThe current evidence shows that Tai Chi can improve the balance function of middle-aged and the elderly, reduce the fall rate, and have a certain preventive effect on falls. Due to limited quality and quantity of the included studies, more high quality studies are required to verify the above conclusion.
Objective To estimate the population attributable disease burden (PAD) of low bone mineral density (LBMD) related fractures among Chinese people over 50 years old from 1990 to 2023, using data from the Global Burden of Disease Study 2023 (GBD 2023), and to provide evidence for prevention strategies and health resource allocation. Methods Based on the GBD 2023, the LBMD summary exposure values (SEV), fracture incidence, years lived with disability (YLDs), and LBMD-related falls YLDs of Chinese people over 50 years old from 1990 to 2023 were extracted. PAD was calculated with population attributable fraction (PAF), and an entropy-weight method was applied to evaluate the contribution of individual fracture sites. Temporal trends and sex differences were examined with Joinpoint regression. Results From 1990 to 2023, the age-standardized SEV of LBMD in people over 50 years old showed an overall decline [average annual percent change (AAPC)=−0.564%]. Age-standardized fracture incidence, fracture YLDs rate, and LBMD-related falls YLDs rate all exhibited W-shaped upward trends (AAPC=1.045%, 0.296%, and 0.724%, respectively). PAF-based estimates indicated that LBMD-attributable fracture incidence likewise increased in a “W-shaped” manner (AAPC=0.558%), whereas the corresponding YLDs rate showed an overall W-shaped decline (AAPC=−0.193%). In international comparison, China and the global average displayed broadly concordant directions of change, with greater volatility in China and a progressive narrowing of the gap after 2015. Regarding sex differences, fracture YLDs rates were consistently higher in the males, whereas the other burden indicators were higher in the females; the temporal patterns were similar in both sexes. Entropy weight method identified hip fractures as contributing most to incidence (weight 0.133), and pelvic fractures as the largest contributor to YLDs rate (weight 0.115). ConclusionSince 1990, the LBMD attributable fracture burden in China’s older population has risen, with female and hip or pelvic fractures bearing the heaviest load. Strengthened osteoporosis screening, improved insurance coverage, and targeted health education are urgently needed to curb further increases in disease burden.
Aiming at the gait instability phenomenon under disturbed conditions, domestic and foreign scholars have done some research works, but the relationship between the independent balancing act with the surface electromyographic and gait parameters in the process of instability has yet rarely been involved. In this study, using the gait analysis combined with electromyographic signal analysis, we investigated balance adjustment mechanism of joints and muscles of the human lower limb under the condition of walking on the level trail and after foot heel touching the ground and unexpected sliding. Studying 10 healthy subjects with the unified shoes, we acquired and analyzed the changing rule of the lower limb joint torque, joint angle, and the surface electromyographic of the main muscle groups involved in situations of dry or oid trails. Studies showed that when accident sliding happened, the body would increase ankle dorsiflexion torque moment, knee unbend torque and straight angle, and meanwhile increase the torque of hip extension, and timely adjust muscle activation time (Followed by activation of Tibialis anterior muscle→Rectus femoris→Gastrocnemius→Femoral biceps) to adjust the center of gravity, to maintain balance of the body, and to avoid falling down. The results of the research could be used to explore new ideas and to provide a certain reference value for preventing slip damage, rehabilitation training and development of lower limb walker.
Objective To integrate the falling experience and coping styles of stroke home patients with falls through Meta synthesis, summarize existing problems based on the integration results, and propose suggestions. Methods We searched databases including PubMed, Medline, Embase, Web of Science, etc., from database establishment to January 2023, to collect qualitative studies on stroke patients’ falling experience at home. The quality of included studies was evaluated by “JBI Australian Evidence-based Health Care Centre (2008) Qualitative Research Quality Assessment Criteria”. The results were integrated by integrating methods. Results A total of 6 references were included, and 18 clear research results were extracted. Similar results were summarized and combined to form 6 new categories, and integrated into 3 main themes. The integration results showed that stroke patients with falls had severe psychological problems, poor coping styles, and unmet needs for fall prevention, resulting in reduced social participation and exercise. Conclusions It is necessary to improve the content of fall assessment and provide corresponding fall prevention health education based on the assessment results. It helps stroke patients and caregivers at home to establish correct coping strategies, thereby avoiding the occurrence of falls.
Objective To construct an intervention program for postoperative fear of falling in elderly patients with hip fracture based on cognitive behavioral theory. Methods Based on cognitive behavioral theory and literature review, an initial draft of intervention plan for postoperative fear of falling in elderly patients with hip fracture was constructed. From January to March 2025, after two rounds of expert consultations and revisions, the final plan was formed. Results A total of 16 experts across the country were invited to participate in two rounds of Delphi expert consultations, covering areas such as orthopedic clinical nursing, orthopedic clinical medicine, nursing education, nursing management, rehabilitation therapy, and psychological therapy. The active participation rates for the two rounds of consultations were 94.12% and 100.00%, respectively. The expert authority coefficients were 0.860 and 0.907, respectively, and the Kendall harmony coefficients were 0.369 and 0.524, respectively. Ultimately, a program composed of 5 primary indicators (fall fear management team, fall fear management goals, fall fear assessment, fall fear intervention measures, and post-intervention effect evaluation), 17 secondary indicators, and 31 tertiary indicators was constructed. Conclusion The intervention program for postoperative fear of falling in elderly patients with hip fracture based on cognitive behavior theory constructed in this study is scientific and operable, which can provide reference and guidance for clinical nursing staff.
Objective To evaluate the effect of Otago exercise program (OEP) on fear of falling in central hemiplegia patients in communities. Methods We collected the clinical data of 61 central hemiplegia patients in the Department of Neurology of Pangang General Hospital from January to June 2014. They were randomly divided into treatment group (n=30) and control group (n=31) after discharge. The treatment group had OEP, while the control group had not. After 20 weeks of follow-up, we evaluated fall self-efficacy, balance and mobility of patients in the two groups. Results The OEP adherence rate was 73.3% for the treatment group. In the treatment group, modified fall efficacy scale (MFES) score and Berg balance scale (BBS) score were significantly higher than those before intervention (P<0.05); time up and go test (TUGT) score was significantly lower than that before intervention (P<0.05). In the control group, MFES score, BBS score and TUGT score were not significantly changed (P>0.05). After intervention, MFES score and BBS score of the treatment group were significantly higher than those of the control group (P<0.05), but TUGT score was not significantly different (P>0.05). Conclusion OEP for central hemiplegia patients after discharge can reduce fall self-efficacy and increase balance ability of the patients.
ObjectiveThis study aimed to systematically review the quality of psychometric properties and methodological quality of the Chinese versions of fear of falling assessment tools for the elderly, providing evidence-based guidance for medical staff in selecting high-quality assessment tools. MethodsWe systematically searched CNKI, WanFang Data, VIP, CBM, PubMed, Embase, and Web of Science databases for studies related to the evaluation of psychometric properties and methodological quality of fear of falling assessment tools for the elderly. The search spanned from the inception of the databases to January 19, 2024. Two researchers independently screened literature and extracted data using the consensus-based standards for the selection of health measurement instruments. The COSMIN risk of bias checklist and quality criteria were employed to evaluate instrument measurement characteristics and formulate final recommendations. ResultsFifteen studies involving 11 Chinese versions of fear of falling assessment tools for the elderly were included. None of the studies reported measurement error, cross-cultural validity, or responsiveness. Due to insufficient or uncertain content validity and low or below-quality evidence, all 11 tools received a recommendation of level B. ConclusionAmong the 11 instruments, the Chinese version of IFES demonstrates the most balanced measurement characteristics, along with good reliability and validity. However, further verification of other measurement characteristics of this instrument is warranted.
