The prevalence of musculoskeletal disorders (MSDs) is high among older adults worldwide, significantly affecting their quality of life and overall health. Understanding the prevalence of MSDs and their associated factors is crucial to developing effective preventive and management strategies in Thailand. In this study, we aimed to investigate the prevalence of MSDs and their associated factors among older patients at Walailak University Physical Therapy Clinic. In this retrospective study, we analyzed the medical records of 396 older patients. Data on demographics, underlying diseases, career types, and treatments were collected and analyzed using descriptive statistics chi-squared tests, and logistic regression analysis to determine their associations with MSD prevalence. The overall prevalence of MSDs was 89.90%. MSD prevalence was higher among female patients than among male patients (p < 0.001). The most commonly affected body regions were the lower back, shoulders, and knees. Career type (p < 0.001) had the highest impact on the presence of MSDs after controlling for sex, age, and underlying diseases as covariates in a logistic regression model. Manual labor and heavy industry workers as well as pensioners showed an increased risk of MSDs. While older age was associated with a higher MSD prevalence using chi-squared statistics, it was removed from the logistic regression models. Pensioners were the most likely to receive treatment, indicating the need for targeted interventions for individuals with physically demanding occupations. These findings underscore the importance of targeted interventions and further research on socioeconomic factors, lifestyle behaviors, and comorbidities to manage MSDs among older adults in Thailand.

[Purpose] The aim of study was to examine incidence of injury according to location of injury to develop an injury prevention program for elite badminton players of junior high school, high school, and university. [Participants and Methods] We conducted a prospective longitudinal study, between April 2012 and March 2013, on 133 national-level badminton players attending junior high school, high school, and university. Injury rates in athletes per 1,000 exposures were calculated based on gender and school age for the five most common injury locations, in addition, severity, type and circumstance were investigated. [Results] Injury rates in athletes per 1,000 exposures were the highest in the racket-side (RS) shoulder/clavicle among the female university students (4.35), RS thigh of high school females (2.21), and lumbar spine/lower back of males of all school ages and junior high school females (1.83–1.25). Significantly higher injury rates were noted for the overuse of the lumbar spine/lower back and RS shoulder/clavicle, trauma of the RS thigh and ankle, and injury, when compared with slight injury of the RS ankle. [Conclusion] Injury prevention programs should be developed for RS shoulder/clavicle overuse in university females, RS thigh trauma in high school females, and lumbar spine/lower back in males of all school ages and junior high school females.

Locomotive syndrome (LS) predisposes older adults to falls and functional dependency. In older adults with LS, the validity of the Lower Quarter Y Balance Test (YBT-LQ)—a dynamic balance assessment tool—remains unclear. This cross-sectional study aimed to assess the convergent validity of the YBT-LQ with the Two-Step and Timed Up and Go (TUG) tests and compare YBT-LQ performance between individuals with and without LS. Sixty Thai community-dwelling older adults (≥60 years) were equally divided into LS and non-LS groups and performed the YBT-LQ, Two-Step test, and TUG test. Correlation analyses and independent t-tests assessed relationships and between-group comparisons, respectively. The YBT-LQ exhibited moderate positive correlations with the Two-Step test (r = 0.366, p = 0.004) and moderate negative correlations with the TUG test (r = −0.412, p = 0.001). The LS group exhibited significantly lower YBT-LQ scores across all reach directions than the non-LS group (p < 0.05), highlighting impaired balance in individuals with LS. The YBT-LQ is a valid and reliable tool for assessing dynamic balance and postural control, as well as identifying multidirectional stability deficits in older adults, particularly those with LS. Implementing the YBT-LQ in routine geriatric evaluations could enhance early detection and targeted interventions to reduce fall risk and improve mobility in aging populations.

Locomotive Syndrome (LS), a condition related to impaired mobility, is influenced by balance control, which comprises six components. Deficiencies in these components can lead to reduced mobility and decreased quality of life. This study aimed to evaluate the relationship between the components of postural control and LS in older adults using the Brief-BESTest. Therefore, this cross-sectional study involved 122 elderly participants from Tha Sala District, Nakhon Si Thammarat Province, both with and without LS. Participants underwent assessments using the Instrumental Activities of Daily Living (IADL) assessment, the Thai Mental State Examination (TMSE), the Two-Step Test, and the Brief-BESTest. The Brief-BESTest covers six balance components: Biomechanical Constraints, Stability Limits, Anticipatory Postural Adjustments, Postural Responses, Sensory Orientation, and Stability in Gait. Descriptive statistics were used to summarize participant characteristics, and Chi-square tests were conducted to examine the relationship between each balance component and LS. Cramer’s V was used to assess the strength of the relationships. The results showed the average age of the sample was 67.67 ± 6.01 years with 85.20 percent female and 14.80 percent male. There were significant relationships between LS and three balance components: Biomechanical Constraints (Chi-square = 5.35, p = 0.021, Cramer’s V = 0.209), Stability Limits (Chi-square = 5.00, p = 0.025, Cramer’s V = 0.204), and Anticipatory Postural Adjustments (left: Chi-square = 4.12, p = 0.042, Cramer’s V = 0.213; right: Chi-square = 5.50, p = 0.019, Cramer’s V = 0.213). No significant associations were found for Reactive Postural Response, Sensory Orientation, and Stability in Gait. These findings suggest that targeted interventions focusing on specific balance components consist of Biomechanical Constraints, Stability Limits, and Anticipatory Postural Adjustments could help reduce the risk of LS in older adults.

Locomotive syndrome, characterized by impaired mobility due to musculoskeletal disorders, poses a significant public health challenge, especially in the aging population. Locomotive syndrome limits physical activity, increases fall risk, leads to dependency, and diminishes quality of life. Effective interventions are urgently required. This systematic review and meta-analysis aimed to evaluate the effectiveness of physical therapy in improving the symptoms of locomotive syndrome. A systematic evaluation of its effectiveness compared with other interventions is crucial for informing clinical practice and policy decisions. This systematic review and meta-analysis follows the PRISMA-P guidelines. Studies involving individuals diagnosed with locomotive syndrome, without restrictions on age, sex, or location, were included. The interventions that are reviewed encompass exercise programs, manual therapy, neuromuscular stimulation, and balance training, which are be compared with no intervention or alternative therapies. The primary outcomes include improvements in functional mobility and physical performance, a reduction in symptoms, and the progression of locomotive syndrome. Secondary outcomes include adherence to therapy, safety, quality of life, patient satisfaction, and psychological well-being. Randomized controlled and non-randomized controlled trials published in English were searched from PubMed, CENTRAL, CINAHL, PEDro, Ichushi Web, and the Thai-Journal Citation Index Center. Independent reviewers performed data extraction and assess the risk of bias. A meta-analyses was conducted using RevMan 5.4 software, with subgroup analyses to address heterogeneity. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to evaluate the certainty of evidence. This review aims to provide robust evidence on the effectiveness of physical therapy in managing locomotive syndrome and to guide clinical practice and healthcare policy decisions.

This cross-sectional study included 112 community-dwelling older adults aged ≥ 60 years residing in Tha Sala District, Nakhon Si Thammarat Province, Thailand, recruited using a community-based quota sampling approach. Locomotive syndrome (LS) was assessed using the two-step test and classified according to the Japanese Orthopaedic Association criteria. Physical activity was evaluated using the Thai version of the Global Physical Activity Questionnaire across work-related, transportation-related, and recreational domains. Frailty and cognitive status were assessed using the Thai version of the FRAIL questionnaire and the Montreal Cognitive Assessment, respectively. Binary logistic regression analysis was used to examine associations. The prevalence of LS was 74.1%, with 37.5%, 33.0%, and 3.6% in participants classified as having LS stages 1, 2, and 3, respectively. Transportation-related physical activity was significantly associated with lower odds of LS. Frailty and mild cognitive impairment frequently coexisted with LS but were not independently associated with LS after adjustment for age and sex. Transportation-related physical activity emerged as a key protective factor, highlighting the importance of habitual mobility in daily life. Our findings suggest that LS overlaps with, but is not identical to, frailty and cognitive decline in relatively robust community settings. Early screening and mobility-related physical activity may be crucial in preventing functional decline in rapidly aging societies.
