[Purpose] Superficial heat treatment is one of the most widely used physical therapies
for osteoarthritis (OA). We clinically evaluated the effects of local heat treatment and
exercise therapy for knee OA, and evaluated the articular cartilage using magnetic
resonance imaging (MRI) T2 mapping. [Subjects and Methods] Eighteen females aged 50–69
(59.5 ± 8.5 years, mean ± SD) years diagnosed with early-stage knee OA were randomly
assigned using computer-generated random numbers to either a local heat treatment group
(LH group, 9 subjects) or an exercise therapy group (EX group, 9 subjects). These groups
were subjected to a 12-week intervention experiment. MRI T2 mapping was performed for
cartilage imaging and quantitative evaluation. For clinical evaluation, the Japanese Knee
Osteoarthritis Measure (JKOM) and the Timed Up and Go (TUG) test were performed. Both
clinical and MRI evaluations were performed at the beginning and end of the intervention
(0 week (Time 0) and 12 weeks). [Results] The total JKOM score had a significantly
decreased in the LH group at 12 weeks. However, in the EX group the total JKOM scores at
Time 0 and 12 weeks were not significantly different. The TUG time in the EX group was
significant shorter at 12 weeks, whereas it showed no significant change in the LH group
at 12 weeks, though the TUG times of 7 of the 9 patients decreased, exhibiting some
improvement. The T2 value of the LH group was significantly shorter at 12 weeks. However,
the T2 value in the EX group showed no significant change at 12 weeks. [Conclusion] After
local heat treatment using heat- and steam moisture-generating sheets for 12 weeks, we
observed improvements in clinical symptoms and walking abilities. Moreover, positive
effects on cartilage metabolism were suggested.
Our data suggest that the surgical procedure of asymmetrical PSO is to correct the scoliosis, to restore the lumbar lordosis by way of convex-sided posterolateral wedge osteotomy, and may go a long way toward solving the problems of rigid lumbar degenerative kyphoscoliosis.
This study suggests that the combined administration of topical intraarticular, bathed, and IV TXA was effective in reducing blood loss in THA patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
