Pajareya K Mail, Chadchavalpanichaya N , Timdang S

: To study the effectiveness of elastic sleeves in patients with knee osteoarthritis
(knee OA).
: Patients with knee OA attending the outpatient clinic of Siriraj Hospital, who met
the eligibility criteria, were randomly allocated to receive an 8-week treatment protocol. The control
group received acetaminophen, non-steroidal anti-inflammatory drugs (NSAIDs) and education. The
study group received the same treatment, in combination with a daytime elastic knee sleeve. Primary
outcome variable included change in aggregated functional performance time (AFPT).
: In the immediate period after treatment, the study group had a mean improvement
in AFPT of 1.63 seconds more than the control group (95% CI: 0.21-3.05, p
0.025). At the end of the
8'h week, the changes of AFPT were not statistically different between the two groups.
: This study shows small short-term beneficial effects of an elastic sleeve in
patients with knee OA in cases with acute exacerbation.
