Locomotive Syndrome Stage Research Articles

Knee joint dysfunction in the patients immediately before arthroplasty was well reflected by locomotive syndrome, not physical frailty.

We assessed physical function by three different methods in patients with knee osteoarthritis just before total knee arthroplasty (TKA) and investigated the relationship between impairment of mobility and preoperative factors. All patients scheduled to undergo TKA at our hospital were assessed for basic attributes, clinical assessment, radiography, whole-body mode DXA, knee muscle strength. And frailty, sarcopenia, and locomotive syndrome (LS) were evaluated. Among 204 patients (213 knees),172 women, mean age 75.0 years, the overall distribution in frailty was <no: 14.6%, pre-frailty: 58.5%, and frailty: 26.8%>; in sarcopenia <no: 93.3%, yes: 3.4%, and severe: 3.4%>; and in LS <Stage 0: 0%, Stage 1: 3.3%, Stage 2: 11.4%, and stage 3: 85.3%>. Eighty-seven percent of the patients with frailty and 92% with LS stage 3 did not suffer from sarcopenia. Statistically significant relationships were observed between sarcopenia and frailty, while no relationship between LS and frailty or LS and sarcopenia. Multivariate analysis of related factors with severity level for frailty and LS revealed statistically significant correlations for frailty with gait speed and LS with KSS and muscle strength. In the patients with knee OA immediately before arthroplasty, physical frailty and LS was not related with by sarcopenia. Knee joint dysfunction without sarcopenia was well reflected by LS, not by physical frailty.

Association Between Sarcopenic Obesity and Frailty Risk in Community-Dwelling Older Women With Locomotive Syndrome: A Cross-Sectional Survey.

Background Concurrent sarcopenia and obesity in locomotive syndrome (LS) impair activities of daily living and decreaseextremity muscle strength and motor function. However, the increased risk of frailty posed by sarcopenic obesity compared to either sarcopenia or obesity alone remains unclear. Objective To examine the association between sarcopenic obesity and frailty risk in community-dwelling older adult women with LS. Methods This cross-sectional study included 158 women aged ≥65 years with LS stage 1 (age, 74.0 yrs, body mass index, 22.7 kg/m2) according to the Japanese Orthopaedic Association criteria. Bioelectrical impedance analysis was used to measure the skeletal muscle mass index (SMI) and percent body fat (PBF). Participants were classified into four subtypes: normal (non-obesity, non-sarcopenia), sarcopenia (SMI < 5.7 kg/m2), obesity (PBF > 35%), and sarcopenic obesity (SMI < 5.7 kg/m2 and PBF > 35%). Logistic regression analysis was used to adjust for age, body mass index, back pain, knee pain, history of falls, and physical function. Results Among the participants, 52 individuals (32.9%) were classified as frailty risk. The percentage of body phenotypes was 30.4% normal, 32.9% were sarcopenia, 22.8% had obesity (RT1), and 13.9% had sarcopenic obesity. The odds ratios for frailty risk compared to normal were 3.97 (95% confidence interval (CI): 1.51 to 10.4), 1.71 (95% CI: 0.55 to 5.39), and 4.25 (95% CI: 1.34 to 13.5) for sarcopenia (RT2), obesity, and sarcopenic obesity subtypes, respectively, sarcopenia and sarcopenic obesity were significantly associated with frailty risk. Conclusion In older adult women with LS, the presence of sarcopenia or sarcopenic obesity may increase the risk of frailty; however, the addition of obesity does not always further increase this risk. Further investigation of the association between increased body fat and frailty in older adult women is warranted.

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.

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.

Association between advanced glycation end-products and fall risk in older adults: The Yakumo Study.

Advanced glycation end-products (AGEs) are irreversibly and heterogeneously formed compounds during the non-enzymatic modification of macromolecules, such as proteins. Aging and lifestyle habits, such as high-fat and high-protein diets, and smoking, promote AGEs accumulation. This study aimed to investigate the relationship between fall risk and AGEs in community-dwelling older adults. This cross-sectional study included patients from the 2022 Yakumo Study who were evaluated for fall risk index 5-items version, locomotive syndrome stage and AGEs. AGEs were evaluated using Skin autofluorescence (SAF) measured by the AGE reader (DiagnOptics Technologies BV, Groningen, the Netherlands). We divided the participants into two groups according to the presence or absence of fall risk (fall risk index 5-items version ≥6 or not), and investigated the factors associated with fall risk. The fall risk group had a higher age and SAF, and a higher proportion of locomotive syndrome stage >2 than the without fall risk group in patients aged ≥65 years (P < 0.01). The multivariate logistic regression analysis after adjustment of age, sex and body mass index showed that locomotive syndrome stage ≥2 and SAF were independent associators of fall risk in older adults (odds ratio 3.26, P < 0.01, odds ratio 2.96, P < 0.05, respectively). The optimal cutoff value of the SAF for fall risk was 2.4 (area under the curve 0.631; 95% CI 0.53-0.733; sensitivity 0.415; specificity 0.814; P < 0.05). The accumulation of AGEs in skin tissues can be used to screen for fall risk comprehensively. Geriatr Gerontol Int 2024; 24: 517-522.

Association between oral health and locomotive syndrome: a cross-sectional study in Japanese adults

BackgroundMany studies have examined the association between oral health, care needs, and physical function, but few have focused on the association between oral health and locomotive syndrome (LS). We examined the association between LS and oral-health status, such as the number of teeth and chewing function, in an adult population.MethodsThe study included 2888 participants who underwent examinations of motor function and oral health. Individuals with LS stage 1 or higher were classified as having LS, while others were classified as not having it. Logistic regression analysis was performed using the presence or absence of LS as the dependent variable and age, sex, smoking status, drinking habit, exercise habit, walking speed, history of stroke, bone density, body mass index, metabolic syndrome, chewing function, and the number of teeth as independent variables to calculate the odds ratios (ORs) and 95% confidence intervals (CIs) for each independent variable.ResultsWhen the number of teeth and chewing function were included separately in multivariate analyses, the OR for LS was significantly higher for participants with 0–19 teeth than for those with 28 teeth, and for participants with poor chewing function than for those with good function (adjusted ORs, 1.47 [95% CI, 1.01–2.15] and 1.73 [95% CI, 1.37–2.18], respectively). In analyses that included tooth number and chewing function as a combined independent variable, relative to individuals with 28 teeth and good masticatory function, the adjusted ORs were 2.67 (95% CI, 1.57–4.52) for those with 28 teeth and poor chewing function, 1.63 (95% CI, 1.20–2.22) for those with 20–27 teeth and poor chewing function, and 1.83 (95% CI, 1.06–3.18) for those with 0–19 teeth and poor chewing function.ConclusionHaving fewer teeth and poor chewing function may be associated with LS. The maintenance of masticatory function may be important to prevent LS in adulthood.

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.

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.

Relationship between the 25-question Geriatric Locomotive Function Scale and physical function in the elderly people.

Locomotive syndrome (LS) is a condition of reduced mobility. The LS stage can be determined by the stand-up test, two-step test, and 25-question geriatric locomotive function scale (GLFS-25). This study aimed to establish whether the LS stage can be reliably determined using the GLFS-25, and to clarify the correlation between the GLFS-25's six subcategories and physical functions. We administered the GLFS-25 and evaluated physical functions using the stand-up test, the two-step test, handgrip strength, the five-times sit-to-stand test, the 4m walking test, and the duration of single leg standing. We assessed 103 participants over 65years of age. We analyzed the correlation between LS stage and GLFS-25 score, as well as the correlations between physical functions and the GLFS-25's six subcategories. There was a discrepancy between the LS stage determined using the GLFS-25 alone and the LS stage determined using all three tools. ROC analysis revealed a cut-off value of 6 for the discrimination of LS stages 0/1 and 14 for stages 1/2. The analysis revealed an AUC of 0.78 and 0.81, respectively. Among the six subcategories of the GLFS-25, movement-related difficulty, usual care, ADL, and social activities were correlated with mobility functions. In contrast, body pain and cognitive showed no correlation. The GLFS-25 is useful for screening those with severe LS stages; however, evaluation of actual physical function is recommended for precise staging of LS in those with low GFLS-25 scores. Among the six subcategories of the GLFS-25, body pain and cognitive were independent of the other four subcategories.

Effect of a physical therapeutic intervention on locomotive syndrome in the elderly patients with Parkinson’s disease and sarcopenia

Purpose: to evaluate the effectiveness of the effect of physical therapy on the indicators and severity of locomotive syndrome in elderly patients with Parkinson’s disease and sarcopenia.&#x0D; Material and methods: 57 elderly people with Parkinson’s disease in combination with sarcopenia were examined. They were divided into two groups: group 1 (followed the principles of standard protocols of outpatient rehabilitation) and group 2 (followed the physical therapy program, which was developed in terms of patient-centered model of rehabilitation taking into account the specifics of each comorbid condition with the use of functional training on the «Prosedos» platform, therapeutic exercises, massage, occupational therapy, nutrition correction, and patient education). The control group consisted of 24 elderly people without signs of sarcopenia and Parkinson’s disease. The effectiveness of the program was evaluated by the dynamics of 25-question Geriatric Locomotive Function Scale, Dynamic Gait Index, Functional Gait Assessment, Activities Balance Confidence Scale, Modified Parkinson Activity Scale.&#x0D; Results: Elderly patients with Parkinson’s disease and sarcopenia were diagnosed with locomotive syndrome stage 2 (according to the 25-question Geriatric Locomotive Function Scale), which manifested itself as a high risk of falling and deteriorating dynamic balance (according to Dynamic Gait Index, Functional Gait Assessment), decreased confidence in maintaining balance during activities (according to Activities Balance Confidence Scale), violation of activities of daily living (according to Modified Parkinson Activity Scale); it was statistically significantly worse than in their peers (p&lt;0.05). The developed program of physical therapy led to a statistically significant (p&lt;0.05) improvement of all studied parameters of locomotive syndrome in comparison with baseline and the condition of patients who received standard restorative correction.&#x0D; Conclusions: Elderly patients with comorbid pathology (Parkinson’s disease and sarcopenia) need new physical therapy programs considering the specifics of each disease and its correcting, the presence of locomotive syndrome to improve social and domestic activity of patients and reduce health risks associated with geriatric syndromes – falls and frailty.

Evaluation of Sit-to-Stand Movement in Older Adults with Locomotive Syndrome Using the Nintendo Wii Balance Board.

Standing up from a chair is a mechanically demanding daily motion, and its biomechanics represent motor performance. In older adults with locomotive syndrome (LS), sit-to-stand (STS) movement with adequate postural control is essential to prevent falls. This study evaluated the characteristics of dynamic balance during STS movement on older adults with LS. A total of 116 participants aged ≥65 years were divided into Non-LS, LS stage 1, and LS stage 2 groups using the LS risk test. The participants were instructed to stand on the Nintendo Wii Balance Board as quickly as possible, and the STS movement was quantified using the vertical ground reaction force (VGRF) and center of pressure (CoP). The STS score, which represented dynamic balance, was significantly different among the groups (p < 0.001). The rate of VGRF development was significantly lower in the LS stages 1 and 2 than in the Non-LS group (p < 0.001). On the other hand, the total distance of the CoP path did not differ among the groups (p = 0.211). These findings indicated a reduction of postural control in older adults with LS. The STS score emphasized the importance of balance training to prevent falls in older adults with LS.

Locomotion training addition to regular aerobic exercise improves walking speed and two-step test of the institutionalized older adult with Locomotive Syndrome stage 1: a randomized controlled trial

Background: Most nursing homes in Indonesia use only aerobic exercise as regular exercise for their resident. Locomotion Training is a combination of lower extremity strengthening and balance exercises. This study aims to determine the effects of the addition of locomotion training to regular aerobic exercise on Walking Speed (WS) and Two Step Test (TST) of institutionalized older adults with the locomotive syndrome (LS) stage 1. Methods: 24 older adults with locomotive syndrome stage 1 (mean age, 73.85 years) participated in the study and were randomly allocated to the Locomotion Training addition group (LTG) and control group (CG). Eight weeks of daily group-based aerobic exercise were conducted for 30 minutes for both groups. The LTG performed additional locomotion training 3 times per week, with a progressive increase of set and repetition at each activity according to the participant's tolerance. The measurement of WS and TST was collected at baseline and 3 days after the intervention was completed for each participant. Results: Twenty participants completed the study, ten from CG and ten from LTG. The results showed a significant statistical difference in WS and TST in LTG (p &lt;0.05) but no improvement in the CG (p &gt;0.05) after 8 weeks of intervention. Conclusion: In addition to regular aerobic exercise, Locomotion Training can improve WS and TST in the institutionalized older adult with locomotive syndrome stage 1.

Cancer may accelerate locomotive syndrome and deteriorate quality of life: a single-centre cross-sectional study of locomotive syndrome in cancer patients

BackgroundThanks to recent advancement in cancer treatment, an increasing number of cancer patients are expected to live longer with cancer. The ambulatory ability is essential for cancer patients to spend their own independent lives, but locomotive syndrome (LS), a condition of reduced mobility due to impairment of locomotive organs, in cancer patients has been seldom examined.MethodsThis was a single-institutional cross-sectional study. Cancer patients receiving cancer therapy between April 2020 and March 2021 were asked to participate. LS was classified as stage 0–3, and compared with their performance status (PS). Physical component summary (PCS) and mental component summary (MCS) were calculated from the results of Short Form-8. Logistic regression analysis was performed to identify risk factors for LS stage 3.ResultsOne hundred and seventy-six cancer patients were included. The rate of LS was 96.0%. That of LS stage 3 was 40.9% and as high as 29.7% even if limited to those with PS 0. The mean PCS and MCS were both inferior to the national averages. PCS decreased as the LS stage advanced. Old age and underweight were revealed as independent risk factors for LS stage 3.ConclusionsThe ratio of LS in cancer patients was extremely high, and the LS stage correlated with physical QOL. Even those with PS 0 can have severe LS; thus, LS can be a sensitive detector of physical disability of cancer patients than PS. The improvement of LS can be a key to the preservation of their ADL and QOL.

Development of a Method for Evaluating Elderly Mobility Functions Using Acceleration Sensors in Smartphones

Locomotive syndrome (LS) is a condition in which a person's mobility is impaired due to musculoskeletal disorders caused by aging or lack of exercise, signaling an imminent need for primary nursing care. This study aims to develop a smartphone application that can distinguish the LS stage in a safe, simple, and quantifiable manner. Using a six‐axes accelerometer built into the smartphone, acceleration and angular velocity data were collected from elderly subjects performing alternating one‐legged stances at intervals of 2.66 s. Frequency analysis was then performed with a fast Fourier transform (FFT) and an autocorrelation coefficient to compare the data characteristics of subjects with and without LS. Due to huge individual variances, significant differences were not observed between LS and non‐LS, and discriminating the LS stage using frequency analysis was considered difficult in the present study. In contrast, the autocorrelation coefficient showed significant differences between LS and non‐LS in acceleration and angular velocity in specific directions. Using the autocorrelation coefficient of acceleration and angular velocity data to detect the presence of LS was concluded to be effective. © 2023 Institute of Electrical Engineers of Japan.

Exercise improving balance function in the older adult with locomotive syndrome stage 1: a randomized clinical trial

Introduction: Fall risk is generally increased in older adults. The aging process is linked to several balance issues and gait abnormalities in the elderly. A multicomponent exercise program for older persons that combines locomotor training and cardiovascular exercise may help the aged population's balance and strength. This study aims to investigate the effects of aerobic exercise and locomotor training on the elderly's capacity to balance. Methods: This study is a randomized clinical trial with a pre-test and post-test group design. 24 older adults were divided into an intervention group (locomotor training combined with aerobic exercise) and a control group (aerobic exercise only). They underwent locomotor training 3 times a week for 8 weeks under supervision and aerobic exercise 7 times a week 40-70% HR maximal. The pairwise comparisons within-group evaluations, and between-group evaluations used independent- and paired-sample t-tests. Results: One Leg Stance (OLS) and Timed Up and Go (TUG) test intra-group and inter-group differences were significantly higher (p&lt; 0.05). Conclusion: The combination of locomotor exercise and aerobic exercise improves static and dynamic balance in older adults with locomotive syndrome stage 1.

Locomotive syndrome affects the acquisition of long-term care insurance system certification

BackgroundLocomotive syndrome is closely related to the state of long-term care. This study aimed to longitudinally evaluate long-term care certification occurrence in locomotive syndrome using data from the Miyagawa study. MethodsThe study included 470 individuals (168 males, 302 females; mean age, 70.7 years) with no long-term care certification at the time of participation in the study. Locomotive syndrome was classified into three stages (stages 1–3) according to the 25-question Geriatric Locomotive Function Scale. Analysis was performed with long-term care certification occurrence as the endpoint and locomotive syndrome stage as the explanatory variable. ResultsThe median observation period was 6.3 years, and long-term care certification occurred in 69 (34.2%) and 30 (11.2%) of the participants in the locomotive syndrome and no-locomotive syndrome groups, respectively. Independent risk factors of long-term care certification occurrence were locomotive syndrome stage-3 (hazard ratio: 2.27) in the total number of studies, and locomotive syndrome stages 2 (hazard ratio: 2.49) and 3 (hazard ratio: 2.79) in females. Locomotive syndrome stage-3 was an independent risk factor in long-term care certification occurrence due to musculoskeletal disorders (hazard ratio: 3.89). ConclusionsThe higher the locomotive syndrome stage, especially in females, the higher the risk of long-term care certification occurrence.

Association between locomotive syndrome and fall risk in the elderly individuals in Japan: The Yakumo study

BackgroundPatients with locomotive syndrome (LS) are poor ambulatory status and a high risk of requiring nursing care. The purpose of this study is to investigate the relationship between LS and fall risk among community-dwelling elderly individuals. MethodsThe subjects were Japanese elderly individuals aged 65 and over who participated in Yakumo study 2019 (N = 189). We defined the fall risk index 5 items version (FRI-5) ≥6 points as the fall risk group. LS was evaluated by stand-up test, two-step test, and 25-Geriatric Locomotive Function Scale (GLFS-25). We divided the subjects into two groups according to the presence or absence of fall risk, and investigated factors associated with fall risk. ResultsThe fall risk group (30 patients, 15.9%) had higher GLSF-25 (P = 0.001). The results of logistic regression analysis adjusted for age, sex, BMI, and knee osteoarthritis revealed that GLFS-25 (OR: 1.052; 95%CI: 1.009–1.097) was independent factor associated with fall risk. In the ROC analysis, the optimal cut-off value of the GLFS-25 to predict fall risk was 12, which is equivalent to LS stage 1 (AUC 0.688; 95% CI: 0.588–0.787; sensitivity: 0.467, specificity: 0.836). ConclusionsGLFS-25 was associated with fall risk among community-dwelling elderly individuals aged 65 and over.

Improving Capacity of Older Adults with Locomotive Syndrome Stage 1 Living in Nursing Home: A Pilot Clinical Trial.

Aging causes locomotive syndrome (LS), which is characterized by difficulty in walking. The present study determined the effects of locomotion training and regular aerobic exercise programs on the aerobic capacity of older nursing home residents with LS stage 1. This randomized controlled trial included 24 participants aged 60-80 years with LS stage 1 residing in a single nursing home in Surabaya, Indonesia. The participants were randomly assigned to either the locomotion training group (LTG) or the control group (CG). Both the groups performed 30 minutes of a daily group-based aerobic exercise program for 8 weeks. The LTG performed additional locomotion training three times weekly, with three sets per session, gradually increasing to five sets per session according to the participant's tolerance. Two-minute walking test (2MWT) values before and after the 8-week intervention were determined in both the groups and converted to maximum oxygen consumption (VO2max) values. After 8 weeks of intervention, a significant increase in VO2max was observed in both the groups (both p&lt;0.05). The LTG showed a more significant improvement in VO2max (p&lt;0.05) compared to the CG. The study results demonstrated the positive effect of 8 weeks of locomotion training and regular aerobic exercise programs in improving the aerobic capacity of older adult nursing home residents with LS stage 1.

Association between Locomotive Syndrome and Physical Activity in Long-Term Inpatients of Psychiatric Care Wards in Japan: A Preliminary Study

The aim of this cross-sectional study was to determine the status of locomotive syndrome (LS) and the level of physical activity (PA) in long-term inpatients in a psychiatric care ward and to investigate the association between the severity of LS and the level of PA. The study participants consisted of 25 patients aged 55 years or older who had been admitted to a psychiatric care ward for more than one year. The participants’ LS stage was determined and their level of PA was measured using an accelerometer. We also analyzed the correlations between the LS stage test results, level of PA, and values for each assessment item. The LS stage test showed that 84.0% of the participants were at stages 3. The participants’ mean step count was 3089.8 ± 2346.5 steps. The participants’ mean sedentary time was 349.7 ± 68.9 min, which is more than 70% of the total measuring time. Overall, the results indicate that LS stage was significantly correlated to age, ADL, and level of PA. Patients who stay in a psychiatric care ward experience declining motor functioning and lack PA. Deterioration of motor functioning is associated with lack of PA, suggesting the need for physical intervention.

Development of locomotive syndrome in elderly population after COVID-19 outbreak: A population-based cross-sectional study with over 12,000 participants

BackgroundRestrictions during the coronavirus disease 2019 (COVID-19) pandemic have decreased physical activity levels, which may result in locomotive syndrome. This study evaluated the change in locomotive syndrome prevalence and associated risk factors among an elderly population before and after a coronavirus outbreak. MethodsThis written self-administered cross-sectional survey was conducted in conjunction with the coronavirus disease vaccination program in Habikino City, Japan. Participants who were aged ≥65 years completed the five-question Geriatric Locomotive Function Scale before and during the pandemic. The diagnosis of locomotive syndrome and its stage was based on the Geriatric Locomotive Function Scale score: stage 1 (2–3 points), 2 (4–5 points), and 3 (≥6 points). Data on lifestyle changes, including regular exercise, during the pandemic were collected. ResultsThis study included 12,197 participants (36.7% of the city’s total elderly residents). The prevalence of locomotive syndrome increased from 41.3% to 47.1% after the outbreak. In total, 765 (6.3% of overall population) and 295 (9.5% of the participants who had stages 1–2 before the pandemic) participants developed locomotive syndrome and stage 3 locomotive syndrome, respectively. The multivariate logistic regression analysis indicated that a decrease in exercise was significantly associated with the onset of locomotive syndrome (all stages) (odds ratio = 2.5, p < 0.001) and locomotive syndrome stage 3 (odds ratio = 2.6, p < 0.001). ConclusionsExtrapolation of the study’s findings to the entire population of Japan suggests that approximately 2 million elderly individuals might develop locomotive syndrome after the coronavirus outbreak. Additionally, 10% of the participants with mild-moderate locomotive syndrome before the pandemic may develop severe locomotive syndrome after the outbreak. The greatest risk factor for new-onset or worsening locomotive syndrome was a decrease in daily exercise. Thus, there is an urgent need for adequate exercise guidelines during the coronavirus pandemic, especially for the elderly population.
