Latar belakang : Penegakan miastenia gravis (MG) didasarkan pada gejala klinis, pemeriksaan fisik dan pemeriksaan penunjang, sampai saat ini belum ada pemeriksaan yang menjadi standar utama dalam penegakan MG. Pemeriksaaan dalam penegakan MG yang hasilnya cepat, tidak invasif dan mudah dilakukan serta biayanya murah yaitu ice pack test (IPT) dan Repetitive Nerve Stimulation (RNS).
Metode: Disain penelitian potong lintang menggunakan data primer dan rekam medis pasien yang dicuriga MG dengan ptosis di Poliklinik Saraf, Instalasi Gawat Darurat (IGD), dan Ruang Rawat Inap di RSUPN Cipto Mangunkusumo (RSCM) sejak Juli 2019 – November 2019.
Hasil: Dari 38 subjek penelitian dengan ptosis, didapatkan 35 subjek terkonfirmasi MG (SF-EMG/Achr antibodi/respon terapi), 19 di antaranya (54,29%) MG jenis okular dan 16 (45,71%) MG jenis general. Hasil ice pack test positif pada 29 subjek (76,3%). Hasil uji diagnostik pemeriksaan ice pack test diperoleh sensitivitas 80%, spesifisitas 66,67%, nilai AUC 73,3%; Hasil uji diagnostik pemeriksaan RNS diperoleh sensitivitas 60%, spesifisitas 100%, nilai AUC 80%; Sedangkan uji diagnostik kombinasi pemeriksaan diperoleh sensitivitas 94,28%, spesifisitas 66,67%, nilai AUC 80,5%.
Kesimpulan: Kombinasi pemeriksaan Ice Pack Test dan Repetitive Nerve Stimulation (RNS) memiliki nilai diagnostik yang baik, sehingga dapat digunakan sebagai pemeriksaan penunjang untuk menegakkan diagnosis MG di RSUPN Cipto Mangunkusumo.
Background: Diagnosis of myasthenia gravis (MG) is based on clinical symptoms, physical examination and supporting examination, so far there has been no examination that has become the main standard in the enforcement of MGSupporting examination of MG that are fast, non-invasive and easy to do are ice pack test (IPT) and Repetitive Nerve Stimulation (RNS).
Methods: This study was conducted with cross-sectional design using primary data and medical records of suspicious MG patients with ptosis in Cipto Mangunkusumo General Hospital between july-november 2019.
Results: Of the 38 subjects with ptosis, 35 subjects were confirmed MG with SF-EMG/AChR antibodies/respon therapy, 19 (54,29 %) ocular type and 16 (45,71%) general type. The ice pack test was positive in 29 subjects (76,3 %). The diagnostic test results of the ice pack test has sensitivity 80%, Specificity 66,67%, AUC(area under the curve) value 73,3%; the RNS has sensitivity 60%, Specificity 100%, AUC value 80%; while the combination test has sensitivity 94,28%, Specificity 66,67% and AUC(area under the curve) value 80,5%
Conclusions: The combination of IPT and RNS has good diagnostic value, so that it can be used as a supporting examination to diagnosis of MG in Cipto mangunkusumo general hospital.

ABSTRAK
Latar belakang: Penilaian kualitas hidup pasien multipel sclerosis (MS) belum rutin digunakan di Indonesia karena belum terdapatnya kuesioner spesifik berbahasa indonesia yang valid. Tujuan dari penelitian ini adalah untuk adaptasi lintas budaya dan validasi kuesioner kuesioner MSQOL-54 versi Indonesia (MSQOL-54 INA).
Metode: Adaptasi lintas budaya dilakukan sesuai dengan metode forward-backward terstandar. Uji psikometri dilakukan dengan menilai reliabilitas (α Cronbach), validitas interna (item internal consistency, item discriminant validity dan analisis fakorial) dan validitas eksterna dengan menilai korelasi dengan faktor klinis EDSS dan faktor demografis lainnya.
Hasil: Uji reliabilitas α Cronbach menunjukkan konsistensi internal yang baik (>0,7) di setiap domain kecuali domain persepsi kesehatan (0,665) dan fungsi sosial (0,433). Validitas bentuk dengan komputasi koefisien korelasi menunjukkan konsistensi konsistensi internal yang sesuai dengan dimensi MSQOL-54 asli. Berdasarkan analisis faktorial domain energi, keterbatasan peran akibat masalah emosional, fungsi sosial dan persepsi kesehatan tidak sesuai dengan dimensi asli. Validitas eksternal dengan EDSS menunjukkan korelasi negatif pada semua domain kecuali fungsi seksual, kemaknaan yang signifikan secara statistik ditemukan pada kedua skor komposit.
Kesimpulan: Kuesioner MSQOL-54 INA memilki reliabilitas yang baik dan terbukti valid serta dapat diterima dengan baik oleh pasien MS di Indonesia. Selanjutnya kuesioner ini dapat digunakan oleh klinisi indonesia untuk tata laksana MS yang lebih komprehensif.
ABSTRACT
Background: Quality of life assessment of patients with multiple sclerosis (MS) is not routinely performed in Indonesia due to the unavailability of the validated Indonesian version of a specific instrument. The objective of this study was to transculturally adapt and validate the Indonesian version of the MSQOL-54 (MSQOL-54 INA) questionnaire.
Methods: The transcultural adaptation was conducted by performing a standardized forward-backward method. Psychometric analysis was performed by assessing the reliability (Cronbach α), internal validation (item internal consistency, item discriminant validity and factorial analysis) and external validation by measuring the correlation with a clinical factor such as EDSS and other demographic factors.
Results: Reliability test with Cronbach α showed good internal consistency (>0.7) at each domain, except for health perception (0.665) and social function (0.433). Construct validity using computation of correlation coefficient showed internal consistency in accordance with the original MSQOL-54 standard dimension. Factorial analysis showed that energy, role limitation due to emotional problems, social function and health perception is not in accordance with the original version. External validation with EDSS showed negative correlation on almost all components, except for sexual function, but both composite scores were statistically significant.
Conclusion: MSQOL-54 INA questionnaire has good internal reliability and is proven to be valid and well-accepted by Indonesian MS patients. Therefore, it can be used by Indonesian clinicians for more comprehensive MS management.
