Abstract

Prevalensi OA lutut berdasarkan diagnosis radiologis di Indonesia cukup tinggi, yaitu mencapai 15,5% pada pria dan 12,7% pada wanita. Nyeri adalah gejala yang paling penting dari OA dan alasan mengapa orang mencari perawatan medis. Tingkat keparahan nyeri berhubungan langsung dengan derajat kelemahan otot. Kelemahan Otot Quadriceps femoris telah terbukti berkorelasi dengan nyeri lutut dan cacat fungsional. Penurunan Otot Quadriceps femoris menyumbang 15% sampai 20% dari kecacatan fungsional ekstremitas bawah dan 5% dari nyeri lutut yang terkait dengan OA. Oleh karena itu, salah satu tujuan intervensi terapi fisik untuk pasien dengan OA adalah untuk meningkatkan kekuatan otot-otot sekitar sendi lutut. Penguatan penting karena otot yang lebih kuat meningkatkan stabilitas sendi dan mengurangi rasa nyeri. Penelitian ini bertujuan untuk membuktikan adanya pengaruh latihan penguatanOtot Quadriceps femoris terhadap derajat nyeri pasien OA lutut. Metode yang digunakan adalah uji klinis terbuka paralel dengan randomisasi. Dimana subjek penelitian dibagi menjadi dua kelompok; yang diberikan Quadriceps Exercise (QE) dan yang tidak (non-QE) dan diamati skor WOMAC nyeri-nya selama 10 minggu. Hasil uji statistik menunjukkan bahwa Setelah 10 minggu masing-masing kelompok responden diberikan terapi, didapatkan rata-rata derajat nyeri kelompok QE sebesar 13,09 dan non-QE sebesar 21,91. Didapatkan juga nilai P=0,008, karena nilai P kurang dari 0,050, maka diambil kesimpulan bahwa hasil uji perbedaan skor nyeri antara kedua kelompok secara statistik telah memperlihatkan perbedaan signifikan. Quadriceps Exercise yang dilakukan rutin selama 5 minggu sudah memberikan pengaruh penurunan derajat nyeri yang signifikan (p<0,05). Quadriceps Exercise yang dilakukan rutin selama 10 minggu juga masih tetap memberikan pengaruh penurunan derajat nyeri yang signifikan (p<0,05). Latihan penguatan Otot Quadriceps femoris akan meningkatkan Range of Motion sendi dan kemudian merangsang neurofisiologi stimulus nociceptive (reseptor tipe IV yang ditemukan pada kapsul fibrous, ligamen,bantalan lemak sendi, periosteum, dan dinding pembuluh darah). Penurunan nyeri terjadi melalui neuromodulasi pada innervasi sensorik mekanoreseptor sendi sehingga pintu gerbang nyeri tertutup oleh inhibisi transmisi stimulus nosiseptive pada spinal cord dan level batang otak. Sehingga dapat disimpulkan bahwa latihan penguatan Otot Quadriceps femoris dengan metode isotonik dapat mengurangi derajat nyeri pasien OA lutut.

English Abstract

The prevalence of knee OA based on radiological diagnosis in Indonesia is quite high, reaching 15.5 % in men and 12.7 % in women. Pain is the most important symptom of OA and the reason why people seek medical care. The severity of pain is directly related to the degree of muscle weakness. Quadriceps femoris muscle weakness has been shown to correlate with knee pain and functional disability. Decreased Quadriceps femoris muscle accounts for 15 % to 20 % of lower extremity functional disability and 5 % of knee pain associated with OA. Therefore, one of the goals of physical therapy interventions for patients with OA is to increase the strength of the muscles around the knee joint. Strengthening important because stronger muscles improve joint stability and reduce pain. This study aims to prove the impact of Quadriceps femoris muscle strengthening exercise on the degree of pain in patients with osteoarthritis of the knee. The method used is an open clinical trial in parallel with randomization. Where research subjects were divided into two groups; given Quadriceps Exercise ( QE ) and that did not ( non - QE ) then WOMAC pain scores observed for 10 weeks. Statistical test results showed that after 10 weeks of each respondent group given therapy, obtained an average degree of pain QE group was 13.09 and 21.91 for non - QE. Also obtained P value = 0.008, because the P value of less than 0,050, it is concluded that the test results of the difference in pain scores between the two groups was statistically significant difference has been demonstrated. Quadriceps Exercise is done routinely for 5 weeks already giving effect a significant reduction in pain intensity ( p < 0.05 ). Quadriceps Exercise done regularly for 10 weeks also still give the effect of a significant reduction in pain intensity ( p < 0.05 ). Quadriceps femoris muscle strengthening exercises will improve Range of Motion joints and then stimulate the nociceptive stimulus neurophysiology (type IV receptors are found in the fibrous capsule, ligaments, fat bearing joints, periosteum, and blood vessel walls). Decrease in pain occurs through sensory innervation mechanoreceptor neuromodulation the joints so that the gate is closed by the inhibition of pain transmission in the spinal cord nociceptive stimulus and the level of the brain stem. It can be concluded that the Quadriceps femoris muscle strengthening exercise with isotonic method can reduce the degree of pain in patients with knee osteoarthritis.
