Objectives: Physical activity management through smartphone applications is increasing worldwide; however, it is unclear whether smartphone users among elderly Japanese individuals with musculoskeletal disorders are less likely to experience “locomotive syndrome” (LoS). We aimed to test the hypothesis that LoS in smartphone users had lower prevalence than that in non-smartphone users among elderly individuals with musculoskeletal disorders. Methods: Elderly participants, aged ≥60 years, who visited the outpatient clinic were enrolled. All participants were asked whether or not they used smartphones and were allocated into either the smartphone group or the non-smartphone group. After completing the 25-question Geriatric Locomotive Function Scale (GLFS-25), LoS prevalence was determined by 3-stage cutoff values of the GLFS-25 score (≥7, ≥16, and ≥24), and the total and three subdomain scores (body pain, movement-related difficulty, and psychosocial complications) were compared between the two groups. Generalized linear regression was then performed to confirm whether the use of smartphones was associated with lower GLFS-25 scores, even after controlling for confounders. Results: Overall, 266 participants, aged ≥60 years, were recruited. LoS prevalence was significantly higher in the non-smartphone group than in the smartphone group at all stages (all p < 0.001). Mean GLFS-25 total and subdomain scores were significantly lower in the smartphone group than in the non-smartphone group (all p < 0.001), and these statistical relationships were maintained even after controlling for age and sex. Conclusions: Smartphone use was associated with low LoS prevalence and low GLFS-25 scores among elderly individuals with musculoskeletal disorders, although the causal relationship remains unclear.
通过智能手机应用进行身体活动管理在全球范围内日益增多；然而，尚不清楚日本患有肌肉骨骼疾病的老年智能手机用户是否不太可能出现“行动不便综合征”（LoS）。我们旨在检验以下假设，即患有肌肉骨骼疾病的老年智能手机用户中 LoS 的患病率低于非智能手机用户。
招募≥60 岁、就诊于门诊的老年参与者。所有参与者均被问及是否使用智能手机，并被分为智能手机组或非智能手机组。在完成 25 项老年机能量表（GLFS-25）后，通过 GLFS-25 评分的 3 个阶段截断值（≥7、≥16 和≥24）确定 LoS 的患病率，并比较两组之间的 LoS 患病率以及总评分和三个子域评分（身体疼痛、运动相关困难和心理社会并发症）。然后进行广义线性回归，以确认即使在控制了混杂因素后，使用智能手机是否与较低的 GLFS-25 评分相关。
共有 266 名≥60 岁的参与者被招募。在所有阶段，非智能手机组的 LoS 患病率均显著高于智能手机组（均 p < 0.001）。智能手机组的 GLFS-25 总评分和子域评分均显著低于非智能手机组（均 p < 0.001），即使在控制了年龄和性别后，这些统计学关系仍然存在。
尽管因果关系尚不清楚，但在患有肌肉骨骼疾病的老年人群中，使用智能手机与较低的 LoS 患病率和较低的 GLFS-25 评分相关。
