Abstract
Knee osteoarthritis (OA) is a common progressive
multifactorial joint disease and is characterized by chronic pain and functional
disability. It is characterized by the deterioration of cartilage in joints which creating
stiffness, pain, and impaired movement. Aim of the study: Evaluate the effect of
physical exercises and heat application on relieving pain and morning stiffness in
osteoarthritis patients. Study design: Quasi-Experimental design was utilized to
conduct the current study. Setting: This study was conducted at the Orthopedic
Outpatient Clinics in Suez- Canal University Hospitals. Subjects: A purposive sample
of (120) adult patients were included in the study as 40 patients assigned into the
control group, 40 patients for the heat group and 40 patients for the physical exercise
group. Data collection tools: Structured interview questionnaire to assess demographic
data and awareness of patients about the disease; in addition to, the self- administered
Knee Injury and Osteoarthritis Outcome Score (KOOS) to assess short and long-term
patient-relevant outcomes following knee injury. Results: This study revealed that
(80%, 100% and 97.5%) and, (32.5%, 15%, 57.5%) of the heat, exercise, and control
group respectively had joint pain and stiffness as dominant symptoms. Heat
application and physical exercises had positive effect on relieve pain, stiffness, and
improvement of physical function. Conclusion: There was statistically significant
difference between heat application and physical exercises on relieving pain, stiffness,
and improvement of physical function; with heat application have the highest effect.
Recommendations: Using a combination of physical exercise and heat application
together for patient with osteoarthritis.
