2.4. Materials 2.4.1. Rapid Upper Limb Assessment (RULA) RULA [10] was used to assess the posture of students working at a computer. RULA focuses on the upper body and is designed to assess a person working at a VDU. 2.4.2. Questionnaire A short questionnaire that sought information on the participant’s age, diagnosis of any postural deformity, or history of recent back or neck injuries was developed. 2.4.3. Body discomfort chart & visual analogue scale A modified Body Discomfort Chart [11] was used. The student marked the area(s) of pain/discomfort on this chart. A set of modified Visual Analogue Scales [12] accompanied the modified Body Discomfort Chart (BDC). Students indicated the level of discomfort in each area indicated on the BDC on separate Visual Analogue Scales (VAS).
