Inclusion criteria
Inclusion criteria: Participants will include men and women aged 65 to 80 years residing in Toyama Prefecture who have chronic low back pain or prefrailty, as well as healthy men and women of the same age range residing in Toyama Prefecture who have neither condition. Based on the definition of the Japanese Society for the Study of Low Back Pain and previous studies, chronic low back pain is defined as nonspecific low back pain persisting for at least 3 months, with either continuous pain during the past 3 months or recurrent episodes of exacerbation and remission within the past 6 months. Prefrailty in this study will be defined using the revised Japanese version of the Cardiovascular Health Study (J-CHS) criteria (2020), with a focus on physical frailty. Participants meeting one or two of the following five criteria will be classified as prefrail: (1) unintentional weight loss of >=2 kg within the past 6 months; (2) grip strength <28 kg in men and <18 kg in women; (3) self-reported exhaustion within the past 2 weeks; (4) usual gait speed <1.0 m/s; and (5) no engagement in either light exercise or regular exercise/sports (defined as answering "not at all at least once per week" to both questions).
