Abstract
BACKGROUND Fractures are a serious consequence following stroke, but it is unclear how these events influence health-related quality of life (HRQoL). We aimed to compare annualized rates of fractures before and after stroke or transient ischemic attack (TIA), identify associated factors, and examine the relationship with HRQoL after stroke/TIA. METHODS Retrospective cohort study using data from the Australian Stroke Clinical Registry (2009-2013) linked with hospital administrative and mortality data. Rates of fractures were assessed in the 1-year period before and after stroke/TIA. Negative binomial regression, with censoring at death, was used to identify factors associated with fractures after stroke/TIA. Respondents provided HRQoL data once between 90 and 180 days after stroke/TIA using the EuroQoL 5-dimensional 3-level instrument. Adjusted logistic regression was used to assess differences in HRQoL at 90 to 180 days by previous fracture. RESULTS Among 13 594 adult survivors of stroke/TIA (49.7% aged ≥75 years, 45.5% female, 47.9% unable to walk on admission), 618 fractures occurred in the year before stroke/TIA (45 fractures per 1000 person-years) compared with 888 fractures in the year after stroke/TIA (74 fractures per 1000 person-years). This represented a relative increase of 63% (95% CI, 47%-80%). Factors associated with poststroke fractures included being female (incidence rate ratio [IRR], 1.34 [95% CI, 1.05-1.72]), increased age (per 10-year increase, IRR, 1.35 [95% CI, 1.21-1.50]), history of prior fracture(s; IRR, 2.56 [95% CI, 1.77-3.70]), and higher Charlson Comorbidity Scores (per 1-point increase, IRR, 1.18 [95% CI, 1.10-1.27]). Receipt of stroke unit care was associated with fewer poststroke fractures (IRR, 0.67 [95% CI, 0.49-0.93]). HRQoL at 90 to 180 days was worse among patients with prior fracture across the domains of mobility, self-care, usual activities, and pain/discomfort. CONCLUSIONS Fracture risk increases substantially after stroke/TIA, and a history of these events is associated with poorer HRQoL at 90 to 180 days after stroke/TIA.

Impact of Stroke History on the Risk of Recurrent Hip Fracture or Major Osteoporotic Fractures among Patients with Incident Hip Fracture: A Nationwide Cohort Study. J Bone Miner Res 2023; 38:278-287. [PMID: 36533810 PMCID: PMC10107617 DOI: 10.1002/jbmr.4760] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/23/2022] [Revised: 11/21/2022] [Accepted: 12/14/2022] [Indexed: 12/24/2022]
Abstract
Considerable uncertainty prevails regarding risk factors for recurrent fracture among older patients with hip fracture. We aimed to investigate the relationship between prefracture stroke history, baseline mobility, and the risk of recurrent hip fracture. This cohort study was based on the Danish Multidisciplinary Hip Fracture Registry, 2011-2018 (n = 48,230). We estimated cumulative incidence (competing risk of death) of recurrent hip fracture and major osteoporotic fractures within 1 and 2 years comparing patients with/without prefracture stroke history. Analyses were performed overall and stratified on baseline mobility status (good mobility: Cumulated Ambulation Score ≥ 5 versus poor mobility: Cumulated Ambulation Score < 5). Using Cox regression, adjusted cause-specific hazard ratios (HRs) with 95% confidence intervals (CIs) were obtained. The 1-year cumulative incidence was 4.6% (95% CI: 3.9-5.4) among patients with stroke history and 4.3% (95% CI: 4.1-4.5) among patients without stroke history. For patients with good mobility, the cumulative incidence of recurrent hip fracture was 5.8% (95% CI: 4.3-7.5) versus 3.7% (95% CI: 3.4-4.0) for patients with versus without stroke history. Corresponding numbers for patients with poor mobility were 4.4% (95% CI: 3.6-5.5) and 5.0% (95% CI: 4.7-5.3). Stroke history was associated with an adjusted HR of 1.55 (95% CI: 1.15-2.10) for recurrent fracture among patients with good mobility. In contrast, no association was observed among patients with poor mobility (adjusted HR 0.88 [95% CI: 0.70-1.10]). The associations were attenuated after 2 years of follow-up and for major osteoporotic fractures. In conclusion, stroke history was associated with slightly higher risk of recurrent fracture among patients with first-time hip fracture in the overall analysis, although the CI included a null result. The association was modified by baseline mobility: Patients with stroke history and good mobility had a markedly higher risk, whereas patients with stroke and poor mobility did not. © 2022 The Authors.

Prognostic Factors of the Inability to Bear Self-Weight at Discharge in Patients with Fragility Femoral Neck Fracture: A 5-Year Retrospective Cohort Study in Thailand. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19073992. [PMID: 35409675 PMCID: PMC8997639 DOI: 10.3390/ijerph19073992] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/22/2022] [Revised: 03/08/2022] [Accepted: 03/25/2022] [Indexed: 12/14/2022]
Abstract
An inability to bear self-weight is one of the unfavorable results in geriatric hip fracture, which needs to be prevented. This study determines pre-operative, intra-operative, and post-operative prognostic factors of the inability to bear self-weight at discharge in patients with fragility femoral neck fracture. This retrospective study was conducted at Chiang Mai University (CMU) hospital with an observational cohort design. Electronic medical records of patients aged ≥ 50 years old with fragility femoral neck fractures between 1 January 2015 and 31 December 2019 were reviewed. Pre-, intra-, and post-operative factors were collected. Ambulation status at discharge time was classified into either ability or inability to bear self-weight. Analysis of prognostic factors was done using multivariable risk ratio regression. In total, 269 patients were recruited in this study. Significantly prognostic factors of inability to bear self-weight at discharge were end-stage renal disease (ESRD), cirrhosis, cerebrovascular disease, pre-fracture ambulatory status, having associated fractures, increasing intra-operative blood loss, and having pressure sore. These prognostic factors could be used to predict patients’ outcomes at discharge. Proper management could then be offered to the patients by the multidisciplinary care team to enhance surgical outcomes.

Abstract
Background Stroke survivors need continuing exercise intervention to maintain functional status. This study assessed the feasibility and efficacy of an interactive telerehabilitation exergaming system to improve balance in individuals with chronic stroke, compared to conventional one-on-one rehabilitation. Methods In this prospective case–control pilot study, 30 Taiwanese individuals with chronic stroke were enrolled and randomly allocated to an experimental group and a control group. All participants received intervention 3 times per week for 4 weeks in the study hospital. The experiment group underwent telerehabilitation using a Kinect camera-based interactive telerehabilitation system in an independent room to simulate home environment. In contrast, the control group received conventional one-on-one physiotherapy in a dedicated rehabilitation area. The effectiveness of interactive telerehabilitation in improving balance in stroke survivors was evaluated by comparing outcomes between the two groups. The primary outcome was Berg Balance Scale (BBS) scores. Secondary outcomes were performance of the Timed Up and Go (TUG) test, Modified Falls Efficacy Scale, Motricity Index, and Functional Ambulation Category. Results Comparison of outcomes between experimental and control groups revealed no significant differences between groups at baseline and post-intervention for all outcome measures. However, BBS scores improved significantly in both groups (control group: p = 0.01, effect size = 0.49; experimental group: p = 0.01, effect size = 0.70). Completion times of TUG tests also improved significantly in the experimental group (p = 0.005, effect size = 0.70). Conclusion The Kinect camera-based interactive telerehabilitation system demonstrates superior or equal efficacy compared to conventional one-on-one physiotherapy for improving balance in individuals with chronic stroke.

Abstract
Background and Purpose Data are lacking on the long-term risk of hip fracture among patients with ischemic stroke. A better understanding of the contemporary incidence of hip fracture after ischemic stroke could benefit patient care by promoting strategies to prevent this disabling complication in stroke survivors. Methods We performed a retrospective cohort study using inpatient and outpatient claims between 2008 and 2015 from a nationally representative 5% sample of Medicare beneficiaries. We included patients ≥66 years of age who were hospitalized with acute ischemic stroke, defined through a validated diagnostic code algorithm. We excluded patients who had a prior or concurrent hip fracture diagnosis at the time of ischemic stroke. The primary outcome was hip fracture requiring hospitalization. Survival statistics were used to calculate crude incidence rates, and the Kaplan-Meier method was used to calculate cumulative rates. Results Among the 1 772 550 beneficiaries in our sample, 60 099 were diagnosed with an acute ischemic stroke without prior or concomitant hip fracture. During 4.5 (±2.2) years of follow-up, the incidence of hip fracture was 1.6 (95% confidence interval [CI]: 1.5-1.6) per 100 person-years in patients with acute ischemic stroke versus 0.6 (95% CI: 0.6-0.6) per 100 person-years in patients without acute ischemic stroke. The cumulative 5-year rate of hip fracture was 7.6% (95% CI: 7.2%-8.0%) among patients with acute ischemic stroke versus 2.8% (95% CI: 2.8%-2.9%) among the remaining Medicare beneficiaries. Conclusion We found that among elderly Medicare beneficiaries with acute ischemic stroke, nearly 1 in 12 developed a hip fracture over the next 5 years.

Abstract
Background Virtual reality (VR) training with motion-controlled console games can be incorporated into stroke rehabilitation programs. The use of a variety of gaming software can provide the patient with an opportunity to perform activities that are exciting, entertaining, and that may not be feasible in clinical environments. The aim of this preliminary randomized controlled study was to investigate the effects of game-based VR canoe paddling training, when combined with conventional physical rehabilitation programs, on postural balance and upper extremity function in 30 patients with subacute stroke. Material/Methods Thirty patients, who were within six months following the diagnosis of stroke, were randomly allocated to either the experimental group (n=15) or the control group (n=15). All participants participated in a conventional rehabilitation program. Also, the experimental group (n=15) performed the VR canoe paddling training for 30 minutes each day, three times per week, for five weeks. After five weeks, outcomes of changes in postural balance and upper extremity function were evaluated and compared between the two groups. Results At five weeks, postural balance and upper extremity function showed significant improvements in both patients groups when compared with the baseline measurements (p<0.05). However, postural balance and upper extremity function were significantly improved in the experimental group when compared with the control group (p<0.05). Conclusions Game-based VR canoe paddling training is an effective rehabilitation therapy that enhances postural balance and upper extremity function in patients with subacute stroke when combined with conventional physical rehabilitation programs.

Abstract
OBJECTIVES This study aimed to investigate the association between thiazide use and the risk of hip fracture after stroke. SETTING A population-based, propensity-matched cohort study was conducted on the basis of Taiwan's National Health Insurance Research Database. PARTICIPANTS Patients with newly diagnosed ischaemic stroke between 2000 and 2011 were included. After propensity score matching, 7470 patients were included, of whom 3735 received thiazides and 3735 did not. OUTCOME MEASURES HRs for developing hip fractures within 2 years after stroke were calculated using Cox proportional hazards regression model with adjustments for sociodemographic and coexisting medical conditions. RESULTS Overall, patients using thiazides after stroke had a lower risk of hip fracture than those not using thiazides (8.5 vs 13.9 per 1000 person-years, adjusted HR=0.64, 95% CI 0.46 to 0.89, p=0.007). Further sensitivity analysis based on the duration of thiazide use revealed that the risk of hip fracture tended to decrease as the duration of exposure of thiazides increased. However, the effect was significant only in patients with long-term use of thiazides (using thiazides for >365 days within 2 years after stroke), with a 59% reduction in the risk of hip fracture when compared with patients not using thiazide (adjusted HR=0.41, 95% CI 0.22 to 0.79, p=0.008). CONCLUSIONS The long-term use of thiazides is associated with a decreased risk of hip fracture after stroke.

Abstract
BACKGROUND AND PURPOSE Falls commonly occur as weight is transferred laterally, and impaired reactive stepping responses are associated with falls after stroke. The purpose of this study was to examine differences in and the determinants of mediolateral (M-L) protective stepping strategies when pulled off balance toward the paretic and nonparetic sides. METHODS Eighteen individuals more than 6 months poststroke were pulled in the M-L direction by a lateral waist-pull perturbation system. Step type (crossover, medial, and lateral) and count were recorded, along with first-step initiation time, length, and clearance. Sensorimotor variables including hip adductor/abductor and ankle plantar flexor/dorsiflexor peak isokinetic torques, paretic foot plantar cutaneous sensation, and motor recovery were used to predict step type by discriminant function analyses (DFAs). RESULTS Regardless of pull direction, nearly 70% of trials required 2 or more recovery steps, with more frequent nonparetic leg first steps, 63.5%. The step type was significantly different for pull direction (P = 0.005), with a greater percentage of lateral steps when pulled toward the nonparetic side (45.1%) compared with the paretic side (17.5%). The M-L step length of the lateral step was increased (P < 0.001), with a reduced step clearance (P = 0.05), when pulled toward the paretic side compared with a pull toward the nonparetic side. DFAs revealed that nonparetic and paretic-side pulls could respectively classify step type 64% and 60% of the time, with foot cutaneous sensation discriminating for pull direction. DISCUSSION AND CONCLUSIONS Balance recovery initiated with the nonparetic leg occurred more frequently in response to M-L perturbations, and paretic foot cutaneous sensation was an important predictor of the stepping response regardless of the pull direction.Video Abstract available for more insights from the authors (see Video, Supplementary Digital Content 1, http://links.lww.com/JNPT/A190).

Abstract
This study systematically reviews prospective and retrospective cohort studies evaluating the risk of hip fracture following stroke. Stroke survivors are at high risk of hip fracture and had a 1.5-fold increased risk compared to stroke-free men and women of the same age. Hip fracture often occurs in ageing and female stroke patients. We performed a meta-analysis to summarize evidence from prospective and retrospective cohort studies about the risk of hip fracture following stroke. We identified English and non-English publications in MEDLINE and EMBASE using stroke and fracture as keywords to 31 December 2015. The data of the incidence of hip fracture were extracted to calculate raw incident rate in stroke survivors as well as risk of hip fractures in strokes comparing populations using a random-effects model. Subgroup analyses were performed to identify the potential influence of some factors. Six prospective and seven retrospective cohort studies were included, involving 512,214 stroke patients with 22,559 hip fractures. The pooled prevalence of hip fractures was 4.87 % (95 % CI, 4.05 to 5.68 %) in stoke patients. We conducted subgroup analysis according to sex, age, duration of follow-up, study design, and region, which showed that female (vs. male) stroke patients older than 70 years (vs. those less than 70 years) and duration of follow-up more than 2 years (vs. those less than 2 years) have higher proportions of hip fractures. Four studies showed that stroke patients had a significantly higher risk of hip fracture compared with the general population, while the other study had a non-significant higher risk. The overall prevalence of hip fracture was 3.28 % (3431 of 104,646) in stroke patients and 2.83 % (36,493 of 1,287,726) in general population, respectively, and the unadjusted combined relative risk of hip fracture was 1.54 (95 % CI, 1.06-2.25). Hip fractures often occur in ageing and female stroke patients.

BACKGROUND Many medications used in older adults have strong anticholinergic (ACH) properties, which may increase the risk of falls and fractures. Use of these medications was identified in a population-based Canadian cohort. OBJECTIVE To identify the fall and fracture risk associated with ACH medication use. METHODS Data collection and analysis were conducted at baseline, year 5, and year 10. Cross-sectional analyses were performed to examine associations between ACH medication use and falls. Time-dependent Cox regression was used to examine time to first nontraumatic fracture. Finally, change in bone mineral density (BMD) over 10 years was compared in ACH medication users versus nonusers. RESULTS Strongly ACH medications were used by 618 of 7753 participants (8.0%) at study baseline, 592 (9.5%) at year 5, and 334 (7.7%) at year 10. Unadjusted ACH medication use was associated with falls at baseline (odds ratio = 1.50; 95% CI = 1.14-1.98; P = 0.004), but the association was no longer significant after covariate adjustment. Similar results occurred at years 5 and 10. ACH medication use was associated with increased incident fracture risk before (hazard ratio = 1.22; CI = 1.13-1.32; P < 0.001) but not after covariate adjustment. Mean (SD) change in femoral neck BMD T-score over 10 years, in those using ACH medications at both years 0 and 5, was -0.60 (0.63) in ACH users versus -0.49 (0.45) in nonusers (P = 0.041), but this was not significant after covariate adjustment. CONCLUSIONS ACH medications were not found to be independently associated with an increased risk of falling, fractures, or BMD loss. Rather, factors associated with ACH medication use explained the apparent associations.

Abstract
Data on overall dietary pattern and osteoporotic fracture risk from population-based cohorts are limited, especially from Asian populations. This study examined the relation between overall diet and hip fracture risk by using principal components analysis (PCA) to identify dietary pattern specific to the study population and by using the Alternative Healthy Eating Index (AHEI) 2010 to assess dietary quality. The Singapore Chinese Health Study is a prospective population-based cohort that enrolled 63,257 Chinese men and women (including both pre- and postmenopausal women) aged 45-74 y between 1993 and 1998 in Singapore. Habitual diet was assessed by using a validated food-frequency questionnaire. Two dietary patterns, the vegetable-fruit-soy (VFS) pattern and the meat-dim-sum (MDS) pattern, were derived by PCA. Overall dietary quality was assessed according to the AHEI 2010, which was defined a priori for chronic disease prevention. A Cox regression model was applied with adjustment for potential confounders. In both genders, higher scores for the VFS pattern and the AHEI 2010 were associated with lower risk of hip fracture in a dose-dependent manner (all P-trend ≤ 0.008). Compared with the lowest quintile, participants in the highest quintile had a 34% reduction in risk (HR: 0.66; 95% CI: 0.55, 0.78) for the VFS pattern and a 32% reduction in risk (HR: 0.68; 95% CI: 0.58, 0.79) for the AHEI 2010. The MDS pattern score was not associated with hip fracture risk. An Asian diet rich in plant-based foods, namely vegetables, fruit, and legumes such as soy, may reduce the risk of hip fracture.
