Pattern of muscle contraction in different postures among Malaysia pineapple plantation workers

Lower extremity disorders is associated with prolonged and awkward postures such as kneeling, squatting and stooping. Current study aims to examine the risk factors of awkward postures among pineapple plantation workers in Malaysia by using Ovako Working Posture Analysis System (OWAS). The postural...
