Experimental: Posture Sequence
Participants will complete computer work on a provided monitor and keyboard for two hours. During the first hour, the research personnel will alter the workstation every ten minutes to test various different postures of the neck, shoulder, arms, and trunk. The sequence will include 3 seated postures and 3 standing postures. At the end of the first hour, the participant will be instructed to adjust the workstation independently and continue to work for 60 minutes for an observational session.
Behavioral: Workstation Modification
Participants are asked to work in a sequence of workstation setups for ten minutes each. The sequence include 1. sitting with workstation adjusted by the participant, 2. sitting with workstation adjusted to promote proper posture, 3. sitting with workstation adjusted to promote unnatural posture, 4. standing with workstation adjusted by the participant, 5. standing with workstation adjusted to promote proper posture, and 6. standing with workstation adjusted to promote unnatural posture. After the sequence of setups, the participant allowed to adjust the workstation in either sitting/standing to work in 60 minutes in their own desired position.
- Change in Pain on the Visual Analog Pain Scale from baseline [ Time Frame: Baseline, every 10 minutes the first hour, every 15 minutes the second hour ]A Visual Analog Pain Scale is a ten-centimeter long line in which participants are asked to place a mark from a minimum of 0 (no pain) to a maximum of 10 (worst pain imaginable). Participants respond to pain, discomfort, or other sensations (i.e. numbness) in their R/L Hand/Wrist, R/L Forearm/Elbow, R/L Shoulder, Neck, Upper Back, Lower Back, R/L Hip/Leg, R/L Foot.
- Posture on the Rapid Upper Limb Assessment [ Time Frame: Every ten minutes the first hour, average across the second hour ]The Rapid Upper Limb Assessment is a screening tool to assess risk of upper limb injury by looking at posture, force, and repetitive/static task. This is assessed using still frame images following the completion of the task.
