OBJECTIVE: The study aimed to compare the effectiveness of different physical
interventions on pain intensity, knee function, and quality of life in patients
with knee osteoarthritis (OA). METHODS: This pilot trial involved 63 patients
(45-55 ?yrs) in a rehabilitation center. Patients were randomly assigned to three
groups: therapeutic exercise alone (TE, n ?= ?21), TE and cryotherapy (TE-Cr, n
?= ?21), and TE and joint mobilization (TE-JM, n ?= ?21). The primary outcome was
pain intensity, secondary outcomes included knee joint function (WOMAC), muscle
strength, knee joint range of motion (ROM), and quality of life (SF-36). Data
were collected at baseline and after 18 days of inpatient rehabilitation.
RESULTS: There were no significant between-group differences in the primary
outcome at baseline. After 18 days, all intervention groups showed significant
improvements (p ?< ?0.05). The TE-JM group reported lower (p ?< ?0.05) pain
levels (3.24 ?± ?1.04) compared to the TE-only (4.76 ?± ?0.77) and TE-Cr (4.86 ?±
?0.57) groups. The TE-Cr group had a lower (p ?< ?0.05) SF-36 total score (52.81
?± ?10.50) than the TE (62.00 ?± ?9.74) and TE-JM (66.62 ?± ?2.87) groups. No
significant between-group differences were observed in ROM or muscle strength.
The WOMAC total score was lower (p ?< ?0.05) in the TE-JM group (27.3 ?± ?13.9)
compared to the TE-Cr group (40.1 ?± ?10.7). CONCLUSION: Although all three
interventions had beneficial short-term effects, leading to reductions in knee
pain and improvements in physical function and quality of life, but no single
intervention demonstrated superior effectiveness across all assessed outcomes.
