Abstract

ABSTRAK

Motor threshold (MT) adalah intensitas minimal yang dibutuhkan untuk membangkitkan respon otot.  Jenis kelamin diduga mempengaruhi motor threshold (MT). Penelitian ini bertujuan untuk mengetahui pengaruh jenis kelamin  terhadap besaran motor threshold menggunakan TMS. Penelitian ini menggunakan desain kuantitatif analitik observasional. Subyek penelitian sebanyak 32 orang, yang terdiri dari 17 laki-laki dan 15 perempuan. Target otot penelitian ini adalah musculus abductor policis brevis kanan dan kiri, dengan asal stimulasi dari transcranial magnetik stimulation (TMS). Hasil penelitian ini didapatkan rata-rata besaran motor treshold kanan sebesar 45% pada laki-laki dan 53% pada perempuan, dengan nilai p= 0,105. Sedangkan rata-rata besaran motor treshold kiri sebesar 46% pada laki-laki dan 45 % pada perempuan, dengan nilai p= 0,771. Sehingga dapat disimpulkan bahwa tidak ada hubungan antara jenis kelamin dengan besaran motor threshold dengan menggunakan TMS.

ABSTRACT

The motor threshold (MT) is the minimum intensity required to evoke a muscle response. Gender is thought to affect the motor threshold (MT). This study aims to determine the effect of gender on the magnitude of the motor threshold using TMS. This study uses an observational analytic quantitative design. The research subjects were 32 people, consisting of 17 men and 15 women. The muscles target in this study were the right and left abductor policis brevis muscles, with the origin of stimulation from transcranial magnetic stimulation (TMS). The results of this study obtained an average right motor treshold magnitude were 45% in men and 53% in women, with p value = 0.105. While the average left motor treshold magnitude were 46% for men and 45% for women, with p value = 0.771. It can be concluded that there was no relationship between gender and the magnitude of the motor threshold using TMS..
