Single Case Study : Pengaruh Latihan Hidroterapi Terhadap Intensitas Nyeri Dan Kemampuan Fungsional Pada Pasien Osteoarthritis Genu

Background: The aging process and life expectancy increase the number of osteoarthritis. One of them is arthropathy of the knee, the main symptoms of which are pain in the knee and a decrease in the patient’s ability to perform functional activities. The purpose of osteoarthritis treatment is to relieve symptoms, improve the patient’s quality of life, and prevent the further development of disease. Although exercise on land is comfortable, pain makes it difficult for patients to carry out weight-bearing physical activities in daily life due to pain, ultimately leading to poor mobility, knee stiffness and muscle weakness. Exercise in water or hydrotherapy has a buoyancy effect (water buoyancy) which has the potential to reduce joint stress, the effect of hydrostatic pressure and water temperature can relieve joint pain.Case description: We report 2 respondents where respondent A is a woman aged 50 years, from radiological examination results with the impression of grade II knee osteoarthritis. Then respondent B is a 44-year-old woman, with radiological examination results with the impression of grade I-II knee osteoarthritis. Intervention: For one month 2 respondents were given hydrotherapy exercises once a week so that respondents received 4 hydrotherapy exercise sessions where one session was 45-60 minutes carried out from May to June 2022. Result: The treatment or intervention carried our by the researcher to 2 respondents by giving 4 session of hydrotherapy exercises, there was a decrease in the intensity of motion pain assessed using NRS and increase in the patient’s functional ability based on the WOMAC questionnaire. Conclusion: Our case shows that hydrotherapy exercise on respondents with osteoarthritis genu dextra grade II and osteoarthritis genu grade I-II can be concluded that hydrotherapy exercise can reduce motion pain intensity and improve functional ability in both respondents
