The goal of this clinical trial is to determine if a wearable back exosuit can make it safer and easier for workers who bend, lift, and lower objects in an industrial setting.
Many studies have shown that wearable back exoskeletons or exosuits can provide helpful forces making a person's back muscles work less. It is believed that exosuits can lower a person's level of workplace effort and fatigue, making it less likely for them to have back pain at work. Back exosuits could be a solution to make a job easier, but how well they work in the real-world over a long period of time is unclear.
The investigators want to know if workers who wear a back exosuit during the workday will have lower rates of lower back pain or injury than those who are not wearing a back exosuit. The investigators also want to know how well exosuit technology integrates into the workplace (for example, how this technology improves or hinders job performance).
Participants will be randomized into an exosuit group or control group. Participants in the exosuit group will be given a back exosuit that they can use as much as they want at work. All participants will complete surveys monthly.
Researchers will compare the exosuit group to the control group to see if using a back exosuit in a workplace can reduce a person's risk and impact of low back injury or pain. The investigators also want to see if a back exosuit impacts job productivity and if participants find the exosuit becomes useful or bothersome over time.

Force and Repetition Measurement of Ham Boning: Relationship to Musculoskeletal Symptoms
Article
Author: Stoy, Daniel W. ; Aspen, Jack
The purpose of this study was to develop a valid methodology for comparing measured torque repetition data along a ham boning line to symptoms reported in an established clinical database, which included history of cumulative stress disorder symptoms. A musculoskeletal stress measurement system was used to measure torque and repetition data associated with boning hams. Twenty-two surveys were conducted across a representative sample of employees performing this task on three different production lines. Two different knife grips were compared in the study to determine if one method produced lower torque. The data were analyzed and work (in-lb) and power (in-lb/sec) calculations were made. Evidence showed an increased rate of reported symptoms by subjects exerting more power as compared to other subjects performing the same task. One method was found to require less power than another. Operators managed a microbreak in the cycle ranging from .88% to 4% of the survey time. Operators not reporting symptoms averaged longer microbreaks than those reporting. The study provided data for structuring a line rotation program for moving people to positions requiring less “power.”
