Assessment of Surgical Outcomes in Patients with Degenerative Cervical Myelopathy Using the 25-Question Geriatric Locomotive Function Scale: A Longitudinal Observational Study.

Locomotive syndrome caused by degenerative musculoskeletal diseases is reported to improve with surgical treatment. However, it is unclear whether surgical treatment is effective for the locomotive syndrome developing in patients with degenerative cervical myelopathy (DCM). Thus, this study primarily aimed to longitudinally assess the change in locomotive syndrome stage before and after cervical spinal surgery for patients with DCM using the 25-question geriatric locomotive function scale (GLFS-25). A secondary objective was to identify factors associated with the postoperative improvement in the locomotive syndrome stage. We retrospectively reviewed clinical data of patients undergoing cervical spine surgery at our institution from April 2020 to May 2022 who had answered the Japanese Orthopaedic Association Cervical Myelopathy Assessment Questionnaire, visual analog scale, and GLFS-25 preoperatively and at 6 months and 1 year postoperatively. We collected demographic data, medical history, preoperative radiographic parameters, presence or absence of posterior longitudinal ligament ossification, and surgical data. We enrolled 115 patients (78 men and 37 women) in the present study. Preoperatively, using the GLFS-25, 73.9% of patients had stage 3, 10.4% had stage 2, 9.6% had stage 1, 6.1% had no locomotive syndrome. The stage distribution of locomotive syndrome improved significantly at 6-months and 1-year postoperatively. The multivariable Poisson regression analysis revealed that better preoperative lower extremity function (relative risk: 3.0; 95% confidence interval: 1.01-8.8) was significantly associated with postoperative improvement in the locomotive syndrome stage. This is the first study to longitudinally assess the locomotive syndrome stage in patients with DCM using GLFS-25. Our results indicated that patients with DCM experienced significant improvement in the locomotive syndrome stage following cervical spine surgery. Particularly, the preoperative lower extremity function was significant in postoperative improvement in the locomotive syndrome stage.

Factors associated with discrepancies in disease activity as assessed by SDAI and RAPID3 in patients with rheumatoid arthritis: Data from a multicenter observational study (T-FLAG).

The present study aimed to examine discrepancies between assessments based on Routine Assessment of Patient Index Data 3 (RAPID3) and Simple Disease Activity Index (SDAI) in RA patients with controlled disease activity. Data from 464 RA patients in SDAI remission or low disease activity (REM/LDA) were analyzed. Patient-reported outcome (PRO) measures, including Health Assessment Questionnaire Disability Index (HAQ-DI), 25-question Geriatric Locomotive Function Scale (GLFS-25), and Kihon checklist (KCL), were assessed. Logistic regression models were used to identify factors associated with RAPID3 moderate or high disease activity (MDA/HDA). Cutoff values of RAPID3 MDA/HDA for each PRO evaluation item were determined using receiver operating characteristic curve analysis. Among RA patients in SDAI REM/LDA, 84.9% were in RAPID3 REM/LDA. Multivariable analysis revealed that HAQ-DI, GLFS-25, and KCL were independently associated with RAPID3 MDA/HDA. Subdomain analysis of KCL revealed that activities of daily living, physical function, cognitive function, and depressive mood were significantly associated with RAPID3 MDA/HDA. Cutoff values for HAQ-DI and KCL were 0.38 and 8, respectively. In RA patients with controlled disease activity, discrepancies between RAPID3 and SDAI assessments were observed, with factors such as HAQ-DI, GLFS-25, and KCL being independently associated with RAPID3 MDA/HDA.

Prevalence and associated factors of locomotive syndrome in young Japanese adults: a cross-sectional study

BackgroundThe onset of locomotive syndrome (LS) precedes that of frailty. Therefore, the first step in extending healthy life expectancy is to implement measures against LS in young adults. The aim of this study was to investigate the prevalence of LS and its associated factors in young adults for early detection and prevention of LS.MethodsThe participants of this study comprised 413 university students specializing in health sciences (192 males and 221 females) with an average age of 19.1 ± 1.2 years. All participants voluntarily participated in the study and reported no serious health problems. The presence or absence of LS was evaluated using the stand-up test, two-step test, and the 25-question Geriatric Locomotive Function Scale. Additionally, musculoskeletal assessment (one-leg standing, squatting, shoulder elevation, and standing forward bend), body composition analysis (weight, body mass index, body fat mass, body fat percentage, skeletal muscle mass index (SMI), and phase angle), handgrip strength test, physical activity assessment, and nutritional assessment were conducted. Sex-stratified analyses were performed, comparing groups with and without LS. Factors associated with LS were explored using binomial logistic regression.ResultsOf the 413 young adults studied, 86 individuals (20.8%) were found to have LS. When stratified by sex, LS was observed to have a considerably higher prevalence in females (55, 24.9%) than in males (31, 16.1%). In males, the notable differences between the groups with and without LS were observed in one-leg standing and phase angle, whereas in females, differences were identified in body fat mass, body fat percentage, SMI, musculoskeletal pain, and handgrip strength. Two types of binomial logistic regression analysis revealed that the inability to perform one-leg standing was associated with LS in males, while the presence of musculoskeletal pain and a high body fat percentage were identified as factors associated with LS in females.ConclusionsOne in five young adults were found to have LS in this study, underscoring the necessity for early intervention and LS health education. Furthermore, effective management of musculoskeletal pain is also crucial.

Significant improvement in locomotive functions after total knee arthroplasty but worse than those of independent ambulatory community dwellers

PurposeThis study investigated the adequacy of improvements in locomotive syndrome (LS) and other clinical outcomes after total knee arthroplasty (TKA) for medial knee osteoarthritis. MethodsA total of 74 patients who underwent unilateral primary TKA were evaluated pre-operatively and 3, 6, and 12 months post-TKA using the 25-question Geriatric Locomotive Function Scale (GLFS-25) to evaluate the severity of LS, the Japanese Knee Osteoarthritis Measure (JKOM), the Knee Society Score (KSS), the timed up and go (TUG) test, and range of motion of the knee joint (ROM). The GLFS-25 score and the severity of LS were compared between these patients and independent ambulatory community dwellers (273 males and 477 females). ResultsThe GLFS-25, JKOM, KSS, TUG scores, and ROM significantly improved post-operatively. The pre-operative incidence of LS stage 3, indicating the worst locomotive function, decreased from 81.1% to 24.3% at the final follow-up. However, the median (interquartile range) GLFS-25 score of 13 (6–23) seemed much worse, and the incidence of LS stage 3 of 24.3% seemed much higher even 12 months post-TKA compared with independent ambulatory community dwellers. ConclusionsThe GLFS-25 score and other clinical outcome scales significantly improved after TKA. However, improvements in locomotive functions were not adequate as approximately 25% of patients remained with LS stage 3. Besides ordinary rehabilitation programmes after TKA, some interventions, such as more rigorous muscle exercises, would be necessary to obtain greater improvements in LS.

Reliability and validity tests of the Chinese version of the Geriatric Locomotive Function Scale (GLFS-25) in tumor survivors

ObjectiveTo evaluate the reliability and validity of the Chinese-translated Geriatric Locomotive Function Scale (GLFS-25) for the assessment of locomotive syndrome (LS) in individuals surviving malignancies. Methods393 tumor survivors at a general hospital in China were recruited. The Chinese version of GLFS-25 was utilized to conduct a cross-sectional survey to ascertain the tool's efficacy in measuring LS in this cohort. The scale's validity was examined through content, structural and discriminant validity assessments, while its reliability was investigated by determining the internal consistency (via Cronbach's α coefficient) and test-retest reliability (via intragroup correlation coefficient, ICC). ResultsThe Chinese-adapted GLFS-25 demonstrated a robust scale-level content validity index of 0.94, while item-level content validity indices ranged from 0.83 to 1.00 across individual items. The suitability of the scale for structural validity assessment was confirmed via exploratory factor analysis, yielding a Kaiser-Meyer-Olkin measure of 0.930 and a significant Bartlett's test of sphericity (χ2 = 3217.714, df = 300, P < 0.001). Subsequent confirmatory factor analysis (CFA) extracted four distinct factors: Social Activity Engagement, Daily Living Ability, Pain Experience and Physical Mobility. These factors accounted for 72.668 % of the variance, indicating substantial construct validity for measuring LS among this population. CFA supported the model's fit with the following indices: χ2/df = 1.559, RMSEA = 0.077, GFI = 0.924, CFI = 0.941, NFI = 0.919, and TLI = 0.933. The factor loadings for the four factors ranged from 0.771 to 0.931, indicating the items corresponding to the four factors effectively represented the constructs they were designed to measure. The correlation coefficients among the four factors were between 0.306 and 0.469, all lower than the square roots of the respective AVEs (0.838–0.867). This suggests a moderate correlation among the four factors and a distinct differentiation between them, indicating the Chinese version of the GLFS-25 exhibits strong discriminant validity in Chinese tumor survivors. Reliability testing revealed a high Cronbach's α coefficient for the overall scale at 0.961, with the subscales yielding coefficients of 0.751, 0.836, 0.930, and 0.952. The overall ICC was determined to be 0.935, with subscale ICCs ranging from 0.857 to 0.941, reinforcing the scale's reliability in this context. ConclusionsThe Chinese version of the GLFS-25 exhibits strong reliability and validity for the assessment of LS in tumor survivors. It may serve as a diagnostic tool for LS, contributing to the prevention and management of musculoskeletal disorders and enhancing the prognosis for this patient population.

A Longitudinal Study on the Effect of Exercise Habits on Locomotive Syndrome and Quality of Life during the Coronavirus Disease 2019 Pandemic.

During the COVID-19 pandemic, this study investigated the potential of exercise habits to improve quality of life (QOL) and prevent locomotive syndrome (LS) in residents of Yakumo-cho, Hokkaido, Japan. Participants from the 2018 health checkup were surveyed in February 2022, focusing on 200 respondents. These individuals were divided based on their 2018 exercise habits (at least 1 h per week): the exercise group (E group) and the non-exercise group (N group), further categorized in 2022 into the 2022E and 2022N groups. QOL was measured using the SF-36 (physical functioning, general health, physical role, physical pain, vitality, social functioning, emotional role, and mental health) and EuroQoL 5-dimension 5-level questionnaires (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression), and LS was assessed with the 25-question geriatric locomotive function scale. These showed no significant change in exercise habits from 2018 to 2022. In the non-LS group, the 2022E group had higher vitality and emotional role functioning scores compared to the 2022N group. For those with LS, the 2022E group reported less physical pain. Notably, the LS incidence was significantly lower in the 2022E group. This study concludes that consistent exercise habits positively impact QOL and reduce the LS risk, underscoring the importance of regular physical activity, especially during challenging times like a pandemic. These findings highlight the broader benefits of maintaining exercise routines for public health, particularly in periods of global health crises. Based on our findings, we recommend that people continue to exercise at least one hour per week to prevent LS.

Relationship between physical activity and locomotive syndrome among young and middle-aged Japanese workers.

This study aimed to examine the relationship between physical activity (PA) and locomotive syndrome (LS) among young and middle-aged Japanese workers. This cross-sectional study included 335 participants from a company in Kumamoto, Japan. LS was evaluated using the 25-question Geriatric Locomotive Function Scale (GLFS-25); a GLFS-25 score ≥7 was defined as LS. Weekly PA was measured using the International Physical Activity Questionnaire. Work-related PA (time spent sitting, standing, walking, and strenuous work per day) and sedentary breaks were measured using a Work-related Physical Activity Questionnaire. Screen usage (television [TV], smartphones, tablets, and personal computers) during leisure time was recorded. The association between PA and LS was examined using a multivariate logistic regression analysis adjusted for age, sex, body mass index, history of musculoskeletal disorders, cancer, stroke, occupation, employment type, work time, shift system, employment status, and body pain. A total of 149 participants had LS. Fewer sedentary breaks during work (>70-minute intervals, odds ratio [OR] = 2.96; prolonged sitting, OR = 4.12) and longer TV viewing time (≥180minutes, OR = 3.02) were significantly associated with LS. In contrast, moderate PA (OR = 0.75) was significantly associated with a lower risk of LS. Fewer sedentary breaks during work and longer TV viewing time could increase the risk of LS in young and middle-aged Japanese workers.

Association between restricted outings and geriatric locomotive function scale score in the general elderly population during the COVID-19 pandemic

BackgroundRestrictions in daily activities due to coronavirus infection countermeasures reduced opportunities for physical activity and social participation in people of all ages. This study investigated the associations of restricted outings on locomotive function during the COVID-19 pandemic using a cohort of middle-aged and elderly community-dwelling residents. MethodsRegistered citizens of 50 to 89 years old were targeted for this investigation. We established 8 groups based on age (50’s, 60’s, 70’s, and 80’s) and gender (male and female) after random sampling from the basic resident registry of Obuse town in 2014. All participants were surveyed by a 25-question geriatric locomotive function scale (GLFS-25) at the time of checkup before the COVID-19 pandemic. Then, in 2021 and 2022 after government restrictions on outings were lifted for COVID-19 pandemic, all participants were mailed questionnaires including the GLFS-25. A total of 296 (143 male and 153 female) participants who responded at least once were included. We evaluated the changes in opportunities to go out between pre- and post-pandemic time points and the impact on GLFS-25 scores. ResultsIn total, 128 (43.2%) respondents had fewer opportunities to go out than the previous year. Pre- and post-pandemic GLFS-25 scores in the decreased outing (+) group were significantly worse than in the decreased outing (-) group (both p<0.01). The final multivariate model revealed GLFS-25 score worsening beta coefficient of 0.27 for age (+10 years), 3.97 for male, 4.54 for decreased outings, and 4.46 for spinal canal stenosis. ConclusionsIn this randomly sampled Japanese cohort based on a resident registry, restricted outings during the COVID-19 pandemic was a significant independent factor associated with lower locomotive function.

Turning and sitting movements during timed up and go tests predict deterioration of physical function in middle-aged adults

BackgroundDeterioration of physical function in middle-aged adults is a significant challenge that can lead to increased risk of future falls. However, a screening method for the functional decline in middle-aged adults has not been established. Research questionTo evaluate the relationship between biomechanical parameters assessed by the timed up and go test (TUG) and locomotive syndrome (LS) in middle-aged adults. MethodsThe inclusion criterion was: under 65 years of age. A total of 97 volunteers (mean age 51.1 years) participated in this study. An LS test was performed, including a 2-step test, a stand-up test, and a 25-question Geriatric Locomotive Function Scale. The TUG was measured using inertial measurement units (IMUs) at comfortable and fast speeds. We then determined the minimum values for anterior-posterior acceleration and angular velocity around the medial-lateral axis, as well as the maximum values of angular velocity around the vertical axis for the upper trunk and sacrum in a TUG phase. ResultsAngular velocity around the vertical axis for upper trunk and sacrum were significantly smaller in LS than non-LS in the turn phase of both speed conditions. For the fast speed condition, the minimum anterior-posterior acceleration for sacrum was greater in LS than in the non-LS condition for the stand-to-sit phase. Angular velocity around the vertical axis for turning and anterior-posterior acceleration from sitting were associated with detection of LS. SignificanceTurning and sitting movements during TUG should be observed using IMU to screen for physical function decline in middle aged adults.

Association between frailty and locomotive syndrome in elderly patients with lumbar spinal stenosis: A retrospective longitudinal analysis.

With the aging society worldwide, lumbar spinal stenosis (LSS) has become common, and its incidence has been increasing worldwide. Frailty and locomotive syndrome significantly overlap as disorders in older people. The current study aimed to validate the association between frailty and locomotive syndrome in patients with LSS. In particular, the involvement of frailty in locomotive syndrome following surgery was examined. We retrospectively reviewed the time-course data of consecutive patients aged ≥65 years who underwent lumbar spinal surgery for LSS. The locomotive syndrome stages were determined using the 25-Question Geriatric Locomotive Function Scale: stage 0, score ≤6; stage 1, score ≥7; stage 2, score ≥16; and Stage 3, score ≥24. Robust, pre-frailty, and frailty were defined as a modified frailty index-11 score of 0, <0.21, and >0.21, respectively. This study included 234 patients. All patients except one were diagnosed with locomotive syndrome preoperatively. Approximately 24.8% of participants were diagnosed with frailty. LSS surgery improved locomotive syndrome regardless of frailty severity. Meanwhile, multivariable analysis indicated that frailty could significantly inhibit improvement in locomotive syndrome after surgery in old patients with LSS (estimated relative risk: 0.6; 95% confidence interval: 0.4-0.9). This study first assessed the association between locomotive syndrome and frailty in patients with LSS. Locomotive syndrome could be managed effectively with surgery regardless of frailty severity in old patients with LSS. However, our findings emphasize the need to screen for frailty preoperatively in this patient group. Geriatr Gerontol Int 2024; 24: 116-122.

The combination of locomotive syndrome and poor sleep quality is a risk factor of falls among community-dwelling middle-aged and older women: A cross-sectional study.

The combination of locomotive syndrome (LS) and poor sleep quality (PQ) has not yet been shown to result in falls or to affect bone conditions in old age and middle age. [Correction added on 1 December 2023, after first online publication: The preceding sentence has been updated for clarity.] METHODS: This cross-sectional study enrolled 2233 community-dwelling middle-aged to older Japanese women. LS and PSQ were assessed by the stand-up test, two-step test, the 25-question Geriatric Locomotive Function Scale, and the Pittsburgh Sleep Quality Index (PSQI). Participants with both LS 1-3 (any) and a PSQI score ≥6 were classified as belonging to the LS(+)/PSQ(+) group. The incidence of falls in the previous month was collected using a self-administered questionnaire. Bone conditions were evaluated using an ultrasonic bone densitometer. The LS(+)/PSQ(+) group independently had a higher risk of falls after adjusting for confounding factors than the LS(-)/PSQ(-) group using multiple logistic regression analysis (odds ratio 1.92, 95% confidence interval 1.01-3.65, P < 0.05). No relationships between LS(-)/PSQ(+) and LS(+)/PSQ(-) groups and the incidences of fall were observed (P > 0.05). [Correction added on 1 December 2023, after first online publication: The two preceding sentences have been corrected to provide greater clarity.] The LS(+)/PSQ(+) group had lower trabecular bone density and cortical bone thickness than the LS(-)/PSQ(-) group (P < 0.05). The combination of LS and PSQ is an independent risk factor of falls, indicating that assessing both LS and PSQ could be useful in detecting middle-aged and older women with low bone density and thickness who fall easily at an early stage. Geriatr Gerontol Int 2023; 23: 912-918.

Impact of spinal surgery on locomotive syndrome in patients with lumbar spinal stenosis in clinical decision limit stage 3: a retrospective study

BackgroundLocomotive syndrome (LS) is characterized by reduced mobility. Clinical decision limit (CDL) stage 3 in LS indicates physical frailty. Lumbar spinal canal stenosis (LSS) is one of the causes of LS, for which lumbar surgery is considered to improve the CDL stage. This study aimed to investigate the efficacy of lumbar surgery and independent factors for improving the CDL stage in patients with LSS.MethodsThis retrospective study was conducted at the Department of Orthopaedic Surgery at our University Hospital. A total of 157 patients aged ≥ 65 years with LSS underwent lumbar surgery. The 25-Question Geriatric Locomotive Function scale (GLFS-25) was used to test for LS, and the Timed Up and Go test (TUG) was used to evaluate functional ability. Lower limb pain was evaluated using a visual analog scale. Patients with at least one improvement in the CDL stage following lumbar surgery were included in the improvement group. Differences in lower limb pain intensity between the groups were evaluated using the Wilcoxon rank-sum test. The Spearman’s rank correlation coefficient was used to determine correlations between Δ lower limb pain and Δ GLFS-25. Logistic regression analysis was used to identify factors associated with improvement in LS.ResultsThe proportion of patients with improved CDL stage was 45.1% (improvement/non-improvement: 32/39). Δ Lower limb pain was significantly reduced in the improvement group compared with that in the non-improvement group (51.0 [36.3–71.0] vs 40.0 [4.0–53.5]; p = 0.0107). Δ GLFS-25 was significantly correlated with Δ lower limb pain (r = 0.3774, p = 0.0031). Multiple logistic regression analysis revealed that TUG and age were significantly associated with improvement in LS (odds ratio, 1.22; 95% confidence interval: 1.07–1.47).ConclusionsLumbar surgery effectively improved the CDL stage in patients with LSS. In addition, TUG was an independent factor associated with improvement in the CDL.

The Relationship between Locomotive Syndrome and Depression in Young Chinese College Students.

This study investigates the relationship between locomotive syndrome (LS) and mental disorder (depression) in young Chinese college students. Our study population (n = 165; mean age of 19.82 ±1.90 years) comprises college student residents at Tsinghua University in Beijing, China. Three screening methods were used to evaluate LS: 25-question Geriatric Locomotive Function Scale (GLFS-25), a two-step test, and a stand-up test. Depression was screened by the Chinese version of the Zung Self-Rating Depression Scale (ZSDS). The prevalence of LS and depression was 20.1% and 30.9%, respectively. The LS group had lower grip strength and higher ZSDS scores than the non-LS group. Young Chinese college students have a relatively high prevalence of LS, and LS and GLFS-25 scores were significantly related to depression. The present results suggest that management strategies for LS should consider depressive symptoms among young adults.

Locomotive syndrome anddepressive symptoms: A cross-sectional study inmiddle-aged women.

Evidence for an association between locomotive syndrome (LS) and depression is lacking in middle-aged women. This study aimed to investigate the relationship between LS severity and depressive symptoms in community-dwelling middle-aged women. This cross-sectional study included 1520 middle-aged women (mean age 52 ± 6 years). LS severity was evaluated using the 25-question Geriatric Locomotive Function Scale questionnaire and motor function test. Depressive symptoms were assessed using the Zung self-rating depression scale. Multiple logistic regression analyses were performed to determine the association between depressive symptoms and LS severity, adjusting for potential confounding factors. LS severity, as evaluated through both questionnaires and motor function tests, was significantly associated with depressive symptoms (self-rating depression scale ≥ 40 points) in middle-aged women. The relationship between LS and depressive symptoms was only significant when assessed through the 25-question Geriatric Locomotive Function Scale questionnaire rather than the motor function tests. Additionally, a stepwise association was observed between pain severity, as assessed by the 25-question Geriatric Locomotive Function Scale, and the prevalence of depressive symptoms. LS severity is significantly associated with depressive symptoms in community-dwelling middle-aged women, suggesting the need for additional mental status assessment in participants with LS and concurrent pain.

THE INFLUENCE OF PHYSICAL THERAPY ON INDICATORS OF LOCOMOTIVE SYNDROME IN ELDERLY PERSONS WITH OSTEOARTHRITIS OF THE KNEE AND OBESITY

Aim: to assess the effectiveness of the developed physical therapy program on locomotive syndrome parameters in elderly people with osteoarthritis of the knee and obesity.&#x0D; Material and methods. 93 elderly people were examined. The control group consisted of 31 people without osteoarthritis of the joints, with no obesity. The main group 1 consisted of 33 people who received rehabilitation according to the general principles of osteoarthritis correction. Representatives of the main group 2 (31 people) were engaged in a physical therapy program using functional training on the «Prosedos» platform, therapeutic exercises, Proprioceptive Neuromuscular Facilitation; massage, kinesiological taping, nutritional correction, patient education. The effectiveness of the program was evaluated according to the dynamics of the Short Physical Performance Battery, Functional Gait Assessment, Tinetti-test (Performance-Oriented Mobility Assessment), 25-question Geriatric Locomotive Function Scale.&#x0D; Results. Elderly patients with osteoarthritis of the knee and obesity were found to have impaired balance (Short Physical Performance Battery), altered gait stereotype (Functional Gait Assessment), risk of falling when performing activities of daily living (Tinetti-test) at the level of locomotive syndrome II degree (25- question Geriatric Locomotive Function Scale). The developed program of physical therapy in persons of the main group 2 revealed a statistically significantly better effect on the components of the locomotive syndrome compared to the initial examination in all studied parameters (p&lt;0.05). Elderly patients who underwent rehabilitation according to the standard program for the correction of osteoarthritis achieved a statistically significant improvement compared to the initial state according to the studied parameters (p&lt;0.05), but less pronounced compared to the tested program.&#x0D; Conclusions. Elderly patients with osteoarthritis of the knee joints and obesity need to develop physical therapy programs taking into account and correcting the specifics of each condition, the presence of static and dynamic balance disorders and the risk of falling, which will increase the overall effectiveness of rehabilitation measures.

Influence of CurQfen®-curcumin on cognitive impairment: a randomized, double-blinded, placebo-controlled, 3-arm, 3-sequence comparative study

BackgroundAlthough curcumin is a blood-brain-barrier permeable molecule with the ability to bind and segregate β-amyloid plaques and neurofibrillary tangles of hyperphosphorylated tau proteins, its poor oral bioavailability, rapid biotransformation to inactive metabolites, fast elimination from the systemic circulation, and hence the poor neuronal uptake has been limiting its clinical efficacy under neurodegenerative conditions.ObjectiveWe hypothesized that the highly bioavailable CurQfen-curcumin (CGM), which has been shown to possess significant blood-brain-barrier permeability and brain bioavailability, would ameliorate dementia in neurodegenerative conditions.MethodsIn the present double-blinded placebo-controlled 3-arm 3-sequence comparative study, 48 subjects characterized with moderate dementia due to the onset of Alzheimer's disease were randomized into three groups (N = 16/group) and supplemented with 400 mg × 2/day of either placebo (MCC), unformulated standard curcumin complex with 95% purity (USC), or CGM as a sachet for six months. The relative changes in cognitive and locomotor functions and biochemical markers were compared.ResultsSupplementation with CGM produced significant (P &amp;lt; 0.05) improvement in the Mini-Mental State Examination (MMSE) and the Geriatric Locomotive Function Scale (GLFS) scores in both intra- and inter-group comparison by 2 × 2 repeated measures (RM) ANOVA. Further, analysis of the serum levels of specific biomarkers (BDNF, Aβ42, tau protein, IL-6, and TNF-α) also revealed a significant (P &amp;lt; 0.05) improvement among CGM subjects as compared to placebo and the USC groups.ConclusionSupplementation with CGM as sachet was found to offer significant delay in the progress of Alzheimer's disease, as evident from the improvements in locomotive and cognitive functions related to dementia.Clinical trial registrationhttp://ctri.nic.in, identifier: CTRI/2018/03/012410.

Association of sarcopenia, pre-sarcopenia, and dynapenia with the onset and progression of locomotive syndrome in Japanese older adults: a cross-sectional study

BackgroundSarcopenia commonly occurs in older adults with motor disorders requiring long-term care, and the clinical features of sarcopenia are associated with locomotive syndrome. Dynapenia is the age-related loss of muscle strength. However, the association of sarcopenia and dynapenia with the onset and progression of locomotive syndrome in older adults remains unknown. The current study aimed to determine the association of sarcopenia, pre-sarcopenia, and dynapenia with the onset and progression of locomotive syndrome in Japanese older adults.MethodsThis study included older females (n = 264, 73.9 ± 5.8 years) and males (n = 92, 76.3 ± 6.1 years). Sarcopenia was defined as low muscle function and mass; pre-sarcopenia was defined as low muscle mass with normal muscle function; and dynapenia was defined as low muscle function without low muscle mass. Locomotive syndrome (stage 0–2) severity was determined using the stand-up test, the two-step test, and the 25-question geriatric locomotive function scale. Logistic regression analysis was performed to determine the relationship between sarcopenia category and locomotive syndrome stages.ResultsAge (1.208, 95% confidence interval (CI) 1.124–1.298), sex (2.455, 95% CI 1.241–4.856), and BMI (1.211, 95% CI 1.077–1.361) were significant variables for determining locomotive syndrome stage ≥ 1, whereas pre-sarcopenia (0.543, 95% CI 0.331–0.891) and sarcopenia (1.664, 95% CI 1.005–2.755) were significant variables for determining locomotive syndrome stage 2.ConclusionsOnly sarcopenia was associated with locomotive syndrome progression, while low muscle mass or low muscle function was not associated with locomotive syndrome. Gaining muscle mass accompanied by an increased muscle function for older adults is warranted to prevent locomotive syndrome progression in the super-aged society.

Severity of locomotive syndrome in surgical cervical spondylotic myelopathy patients: a cross-sectional study.

Although cervical spondylotic myelopathy (CSM) has a marked impact on locomotive function, few studies have evaluated this relationship in terms of locomotive syndrome. Thus, we assessed (i) the stages of locomotive syndrome in preoperative CSM patients using the 25-question geriatric locomotive function scale (GLFS-25), (ii) the correlation between GLFS-25 scores and the Japanese orthopaedic association (JOA) scores or the JOA cervical myelopathy evaluation questionnaire (JOACMEQ) scores, and (iii) the factors associated with stage 3 locomotive syndrome in preoperative CSM patients. We used clinical data from 107 patients scheduled for cervical spinal surgery for CSM. Data were collected prior to surgery, and included age, gender, body mass index, medical history, JOA score, and JOACMEQ and GLFS-25 scores. Of the included CSM patients, 93.5% were diagnosed with locomotive syndrome, of whom 77.6% were stage 3 according to GLFS-25 evaluation. For the correlation between GLFS-25 and JOA or JOACMEQ, the upper and lower extremity function scores of JOACMEQ and the JOA were strongly inversely correlated with the GLFS-25 score. Finally, multivariate analysis suggested that severe lower extremity status in the JOACMEQ was significantly associated with stage 3 locomotive syndrome in preoperative CSM patients. Using the GLFS-25, we found that lower extremity status had the strongest association with stage 3 locomotive syndrome in preoperative CSM patients. These findings are useful for preventing CSM patients from requiring future nursing care.

Impact of spinal sagittal malalignment on locomotive syndrome and physical function in community-dwelling middle aged and older women

BackgroundAdult spinal deformity has a substantially debilitating effect on older people’s physical and mental health. However, the impact of sagittal malalignment on locomotive syndrome (LS), sarcopenia, and physical function in community-dwelling older women has not yet been clarified. This study aimed to investigate the association between these factors in community-dwelling middle aged and older women.MethodsA total of 361 women were recruited from participants performing aquatic exercises in a rural area of Japan. The body mass index, skeletal muscle mass index, trunk muscle mass, spinal inclination angle (SIA), grip strength, timed up-and-go test (TUG), maximum stride of the participants, and one-leg standing time were measured. Low back pain (LBP)- and health-related quality of life (HRQOL) were evaluated using the Oswestry Disability Index (ODI) and the Short-Form 8 questionnaire. Associations between the global sagittal alignment using SIA and investigating parameters were analyzed.ResultsThe prevalence of sarcopenia was 3.6%. The prevalence of LS (stages 1, 2, and 3) was 43.8% (158 of 361), and the number of participants in each LS stage was 203 (stage 0), 95 (stage 1), 28 (stage 2), and 35 (stage 3). The SIA was significantly correlated with the 25-question geriatric locomotive function scale (r′ = 0.292, p < 0.001), ODI (r′ = 0.267, p < 0.001), and TUG (r′ = 0.453, p < 0.001) after adjusting for age. In the receiver-operating characteristic curve analysis, the cutoff values of SIA for LS ≥ stage 2 and ODI ≥ 20% were 5°.ConclusionsLBP-related QOL and physical performance were significantly associated with global sagittal alignment. Global sagittal alignment was correlated with the three-stage category of LS. The spinal inclination of 5° was a cutoff value to predict exacerbation of mobility function and HRQOL status.

Association of depressive symptoms with Geriatric Locomotive Function Scale score in community-dwelling older adults living in the state of emergency

BackgroundUnder the state of emergency, it has been reported that the amount of physical activity among community-dwelling older adults has decreased significantly due to refraining from going out, and there are strong concerns about the Geriatric Locomotive Function Scale and deterioration of mental health. Therefore, this study aimed to investigate whether the depressive state before the coronavirus disease 2019 (COVID-19) pandemic affected the 25-Geriatric Locomotive (GLFS) score during the COVID-19 pandemic among community-dwelling older adults.MethodsThe participants were 194 community-dwelling older adults (45 men, 149 women) with an average age of 75.5 ± 5.5 years who responded to a self-administered survey conducted three times (preliminary, second, and third) from before the 2018 COVID-19 pandemic to March 2021. Individuals with a score of ≥ 10 on the Geriatric Depression Scale 15 (GDS 15) were excluded. The survey items included the 25-question Geriatric Locomotive Function Scale (GLFS25), GDS 15, and other basic attributes. Those with scores of 5 to 9 on the GDS 15 and those with scores of 0 to 4 were assigned to the depressive symptoms (DS) group and the non-DS group, respectively. Statistical analysis was performed using two-way analysis of variance. The Mann–Whitney U test was used for comparisons between the groups.ResultsIn total, 187 patients were included in the analysis, excluding 7 patients. GLFS 25 showed a significant increase in scores at the second and third time points compared with baseline, and a main effect was confirmed in both groups, with no interaction effect. The second time, the score was 10.0 ± 8.5 and 13.7 ± 10.5 in the non-DS and DS groups, respectively. The third time, the non-DS and DS groups scored 10.8 ± 10.5 and 14.9 ± 10.1 points, respectively, indicating a significant difference.ConclusionsOur results revealed that the increase in the GLFS 25 score in community-dwelling older adults during the COVID-19 pandemic was related to their DS during normal times before the pandemic. Evaluating such individuals and providing social support may effectively reduce the deterioration of the GLFS 25 score.
