Rubber tapping is an important occupation in Asia especially in
Thailand, Indonesia, Malaysia, India, and Sri Lanka, with approximately
1.2 million workers in the southern part of Thailand in the
year 2009. However, a previous report revealed that rubber tapping
is a high risk occupation for developing MSDs. Rubber tappers were
reported to have a high prevalence (55%) of low back pain followed
by carpal tunnel syndrome (19%) (Bensa-ard et al., 2004). MSDs
among rubber tappers may relate to possible ergonomic problems
from working such as an awkward work posture and highly
repetitive work.
