315 Open Access Indonesian Journal of Medical Reviews Vol 2 Issue 6 2022 1. Introduction Leprosy is a disease caused by Mycobacterium leprae and is a burden of disease because it causes irreversible disability in sufferers. 1 Disability can occur due to impaired peripheral nerve function. One of the causes of acute damage to nerve function is leprosy reactions. 2 Leprosy reactions can occur before treatment, especially during or after treatment. 3 Although the clinical picture, bacteria, histopathology, and precipitating factors of leprosy reactions are well known, and the exact cause is unknown. This reaction may represent episodes of acute hypersensitivity to bacillary antigens that disrupt the balance of immunity. 3 There are three levels of disability in leprosy, namely levels 0, I, and II. Grade 0 defects are defects that do not show abnormalities due to leprosy; Grade I defects are defects caused by imperceptible sensory nerve damage such as loss of touch in the cornea of the eye, palms of the hands, and soles of the feet; while grade II means visible disability or damage such as claw hand, drop foot, Bell's palsy. 4.5 In 2017, level II disability in Indonesia reached 6.50%. 5 This figure is still above the program indicator of 5%. 4 The level II disability rate of people with leprosy per 10,000 population in Central Java Province in 2017 was 0.53, an increase compared to the level II disability rate in Nerve Function Examination as a Screening for Prevention of Disability in Morbus Hansen at Kelet General Hospital, Central Java: A Case Report Teguh Prihastomo 1* , Wahyu Tri Sudaryanto 2 1 Physiotherapy Professional Study Program, Faculty of Health Sciences, Universitas Muhammadiyah Surakarta, Surakarta, Indonesia 2 Lecturer of Physiotherapy Study Program, Faculty of Health Sciences, Universitas Muhammadiyah Surakarta, Surakarta, Indonesia ARTICLE INFO Keywords: leprosy disability Morbus hansen Neurological examination Range of motion *Corresponding author: Teguh Prihastomo E-mail address: teguhphysio@gmail.com All authors have reviewed and approved the final version of the manuscript. https://doi.org/10.37275/oaijmr.v2i6.247 A B S T R A C T Disability in leprosy or Morbus Hansen can be prevented by early diagnosis and regular and accurate treatment with multi-drug treatment. This study aimed to describe the examination of nerve function in preventing leprosy disability. In this case, a man, 21 years old, has a history of diagnosis of Morbus Hansen multibacillary type since five years ago. There are deformities in both hands and feet with red bumps. On neurological examination, there was anesthesia in hand with paralysis of the finger muscles causing claw hand. No reduction in muscle mass was seen. The patient found it difficult to move his left hand, especially on the 4th and 5th fingers. The range of motion (ROM) of the 4th and 5th fingers was limited. Examination of nerve function begins by palpating the auricular magnus, radial, ulnar, peroneus communis, and posterior tibial nerves. Motor and sensory examinations were carried out by examining the strength of the facial muscles, finger muscles, and wrist muscles. For the lower limbs, examine the muscles of the ankles and toes. In conclusion, early examination of disability and exercise therapy can help prevent disability and keep the condition of disability from getting worse.
