About
Chronic low back pain has been identified as a major problem for seafood and agricultural workers, and is known to affect worker health and productivity. The aims of this study are to: 1) identify modifiable, sector-specific, work and movement solutions with the potential to reduce the burden or severity of chronic lower back pain in clam workers and 2) determine the extent that participants adopt identified solution(s), and the impact on functional difficulty and low back pain.
Full description
This pilot/feasibility pre-post intervention study will use a participatory ergonomic approach without a control group or randomization. The participatory approach will foster capacity building by creating support within the workplace communities and by involving seafood workers in developing context specific solutions for their own work practice, increasing the potential for adoption and success.
Phase 1: Specific Aim 1: Identify modifiable, sector-specific work and movement solutions with that can reduce the burden or severity of chronic lower back pain
Focus groups will be held in the participant's work settings with consented individuals from the same work teams to ensure application within a specific context and promote discussion directed towards the best outcomes. Participants will discuss major tasks and factors contributing to their low back pain using the video clips to target discussions and their opinions of options that would help alleviate or prevent pain. Only clips from the relevant teams will be used for each focus group. The focus groups will be recorded and transcribed for analysis and as a record of discussion.
Basic principles of ergonomic adaptation and movement modification for repetitive work activities on and off the boat and lifting will be introduced using demonstrations and discussion in a small group format. Participants will discuss other possible solutions. Self-management including movement strategies and pain relief techniques will be introduced and demonstrated by the principal investigator. The educational session will be videotaped to ensure all relevant discussions are considered during the development of interventions and to assist with reliability of intervention delivery.
At the end of the focus group and educational session, participants will prioritize their most problematic work tasks and most relevant and feasible solutions. In a follow up visit, participants will be videotaped demonstrating the tasks and selected methods to reduce or prevent repetitive stress determined from the focus group. With permission from the participants, selected videos will be edited to provide clips to be used in subsequent workshops. Only participants who agree to be videotaped for educational purposes will be included in this session.
Phase II: Specific Aim 2: Determine the extent that participants adopt identified solution(s), and the impact of their self-selected work and movement modifications on their functional difficulty in the workplace related to low back pain.
In addition to the workers recruited for specific aim 1, up to 24 additional clam workers for a total of up to 34 participants will be recruited with the same criteria; chronic low back pain for more than 3 months, over the age of 18 and employed full time in clam gathering/preparation.
