Design outcomes

Primary

Measure	Time frame
Occurrence of work-related injuries in subjects with locomo The severity of locomo in subjects is determined using (1) the locomo rise test, (2) the locomo 2-step test, and (3) the locomo 25 interview, as prescribed by the Japanese Orthopaedic Association. Each subject will participate in periodic in-house health checkups for the degree of locomotion, and all of the tests from (1) to (3) will be conducted.	—

Secondary

Measure	Time frame
(1) Basic information Basic information including gender, age, medical history, comorbidities, medications (e.g., antihypertensive medications, benzodiazepines), working hours, type of industry, shift work, membership in sports club, history of falls, anthropometric data (Body Mass Index (BMI), muscle mass), grip strength, standing balance ability, walking speed, and specific health checkup questionnaire The basic information including body composition data (Body Mass Index (BMI), muscle mass), grip strength, standing balance ability, walking speed, and specific health checkup questionnaires are directly measured or interviewed. (2) Loco-mo test The following tests are used to test the degree of locomotion: (1) Loco-mo rise test, (2) Loco-mo 2-step test, and (3) Loco-mo 25 questionnaire, as specified by the Japanese Orthopaedic Association. The criteria for determining the degree of locomo in this study is that if any of the aforementioned tests (1) Rise test, (2) 2-step test, and (3) LOKOMO 25 are applicable, the patient is judged to have locomo.	—
