We investigated the effects of belt electrode-skeletal muscle electrical stimulation (B-SES) on atrophy in collagen-induced arthritis (CIA) rats. Twenty-eight 8-week-old male Dark Agouti rats were immunized with type II collagen and Freund's incomplete adjuvant (day 0). From days 14 to 28, 18 received B-SES (50 Hz) four times only right hindlimb (STIM), while contralateral left remained unstimulated. Both hindlimbs 10 untreated CIA defined as controls (CONT). Paw volume was measured every...

Treatments for rheumatoid arthritis (RA) have improved since methotrexate and biological agents were approved; however, few longitudinal analyses tracked joint destruction, deformity progression, or functional impairments that directly affect the activities of daily living. Due to consequences impairments, we conducted this study glean more information regarding progression over time.This enrolled 134 hands in 67 RA patients with hand deformities 2004. After 5 years, 100 52 eligible final...

Exercise therapy inhibits joint destruction by suppressing pro-inflammatory cytokines. The efficacy of pharmacotherapy for rheumatoid arthritis differs depending on the phase disease, but that exercise each is unknown. We assessed differences in treadmill running at various phases, using rat models. Rats with collagen-induced were used as models, and after immunization was divided pre-arthritis established phases. Histologically, groups forced had significantly inhibited compared other...

Spontaneous flexor tendon rupture is usually caused by trauma, systemic diseases, or carpal bone and joint disorders. Here we report a case of spontaneous occurring in lupus erythematosus (SLE) patient following nonunion the hamate hook after an insufficiency fracture, which was also associated with degeneration SLE. A 57-year-old woman diagnosed SLE 22 years ago being treated oral prednisolone. She became unable to flex her left little finger without any history trauma sporting activity. CT...

The effects of treadmill running under hypoxic conditions on joints and muscles collagen-induced arthritis (CIA) rats were investigated. CIA divided into normoxia no-exercise, hypoxia no-exercise (Hypo-no), exercise (Hypo-ex) groups. Changes examined days 2 44 with or without exercises. In the early stage hypoxia, expression hypoxia-inducible factor (HIF)-1α increased in Hypo-no Hypo-ex egl-9 family 1 (EGLN1) vascular endothelial growth (VEGF) group also increased. Under sustained groups did...

Foot impairment in rheumatoid arthritis (RA) may exacerbate sarcopenia from physical inactivity because of foot pain while walking. The present study aimed to investigate the prevalence patients with RA-associated impairment, and whether treatment a orthosis improved activity muscle quantity.Thirty-two RA were diagnosed as sarcopenic or nonsarcopenic, was determined. Eleven treated orthosis. following parameters compared between baseline after 6 months treatment: (walking, moderate-intensity...

Abstract Background Although drug therapy for rheumatoid arthritis (RA) has recently improved, treating patients with established disease, whose hands have three major deformities (thumb deformity, finger deformities, and ulnar drift), remains a challenge. The underlying complex pathophysiology makes understanding these difficult, comprehensive assessment methods require accumulated skill long learning curves. We aimed to establish simpler composite method understand the of alterations in...

Ambulatory evaluated using a Basic Movement Scale (BMS), motor subscale Functional Independence Measure (motor-FIM). From results evaluating BMS motor-FIM weekly, important postoperative period regain investigated.There...

To establish a new assessment tool for ulnar drift (UD) in rheumatoid arthritis (RA).We established an observational cohort of 67 patients (134 hands) beginning 2004. Fifty-two (100 had follow-up 2009 and 37 (63 completed 2015. UD was evaluated with the Fearnley classification our scoring method, which assesses four parameters metacarpophalangeal joint.

A modified S–K these wrists has been reported, the clinical outcomes of are unclear. This study evaluated 24 20 patients who underwent procedure. mean follow-up period was 34.5 months. assessments were range motion, carpal translation and bony shelf size. motion similar those produced...
