The associations between toe grip strength (TGS) and foot structure are not well known, although is inferred to affect TGS. This study investigated the TGS hallux valgus angle (HVA), curl ability, arch height (FAH).This analysed 227, 20 79-year-old, community-dwelling participants. TGS, HVA formed by first metatarsal bone proximal phalanx of hallux, ability (percentage) calculated as (foot length-flexed length)/foot length, FAH navicular height/truncated length were measured. To elucidate...

In this study, we aimed to identify combined factors associated with lower postoperative quality of life (QOL) in knee replacement (KR) patients, utilising data from the Osteoarthritis Initiative (OAI) database. The 44 individuals OAI who underwent KR surgery was included study. Preoperative baseline data, including demographic information, comorbidities, depressive symptoms, knee-joint and health-related QOL, were analysed using association rule analysis single linked low QOL that assessed...

To evaluate the clinical impact in knee osteoarthritis (OA) of coexisting patellofemoral (PF) joint OA (PFOA) Japanese patients with medial tibiofemoral (TF) (TFOA).Patients (n = 143) were enrolled. The radiographic severity TF and PF joints, anatomic axis angle joint, patellar alignment, trochlear morphology, height, passive range motion (ROM) painful evaluated. Additionally, Knee Osteoarthritis Measure (JKOM) was used to investigate association between presence PFOA symptoms.PFOA present...

[Purpose] This study investigated the relationship between toe grip strength and foot posture in children. [Subjects Methods] A total of 619 children participated this study. The participants was measured using a printer dynamometer. Children were classified into 3 groups; flatfoot, normal, high arch, according to Staheli's arch index. differences demographic data among each group analyzed by analysis variance. Additionally, covariance, adjusted body mass index, age, gender. [Results] number...
