Penelitian ini merupakan penelitian observasional analitik dengan pendekatan cross-sectional Subyek penelitian sebanyak 30 responden merupakan total populasi. Data dikumpulkan melalui pengukuran dan kuesioner. Analisis data menggunakan tabulasi silang perhitungan besar risiko yang menghasilkan RAsio Prevalen (RP) pada Convidence Interval 95%. HAsil penelitian menunjukkan pada umur tua 16,67% terganggu dan 16,67% normal; umur muda 10% terganggu dan 56,66% nornal. Pada masa kerja senior 13,33% terganggu dan 10% normal; masa kerja junior 13,33% terganggu dan 63,34% normal.
