  • Brock experts weigh in on the battle against back pain and other workplace injuries

    EXPERT ADVISORY – October 28, 2024 – R0129

    One of Michael Holmes’ favourite expressions is: “Work shouldn’t hurt.”

    Preventing workplace injuries is the focus of the Brock University Associate Professor of Kinesiology’s research and a key message during October’s Global Ergonomics Month, which raises awareness about the way humans interact with objects and systems to protect their well-being.

    “Every single industry, profession and job can benefit from ergonomic principles,” says the Canada Research Chair in Neuromuscular Mechanics and Ergonomics. “In addition to healthy workers, ergonomics is good for business and can have a positive impact on a company’s bottom line.”

    Holmes says musculoskeletal disorders (MSDs) — injuries or pain to muscles, tendons, ligaments, joints and nerves — account for a large percentage of all workplace injuries.

    “In physical ergonomics, we often consider how much effort is required to do the job, how repetitive it is and what postures workers adopt while performing the job,” says Holmes. “Once we have a grasp of these physical demands, we can better understand fatigue, injury risk and solutions.”

    He encourages companies and employees to:

    Associate Professor of Kinesiology Shawn Beaudette says, “roughly 84 per cent of us will experience lower back pain at least once in our lifetimes” and that “lower back pain is one of the most burdensome disorders people struggle with chronically.”

    Along with his team, the lead of Brock’s Spine Biomechanics and Neuromuscular Control Laboratoryuses a variety of technologies to screen for different types of lower-back disorders and reduce the burden on those suffering with them.

    The lab’s recent study found an increase in lower-back, neck and wrist pain in employees during COVID-19, when many of them switched to using laptops placed on home furniture, rather than desks and adjustable chairs.

    With support from the CSA Group, Beaudette’s team also recently explored the use of a passive back support exoskeleton to offset demand on the spine during repetitive lifting manoeuvres, “demonstrating that exoskeletons can reduce fatigue and improve productivity.”

    Assistant Professor of Engineering Ryan Schroeder researches rehabilitation strategies and equipment that helps people to walk more efficiently.

    He is working to refine a specialized backpack first developed two decades ago by researchers looking to generate an energy source from the carrier’s movement.

    “When you walk, your body moves up and down with every step,” says Schroeder. “The researchers thought that by de-coupling the load from the carrier’s back, they could capture some energy.”

    Not only could the device recharge batteries for electronic devices, but surprisingly, it also made it easier to walk, he says.

    Schroeder recommends taking smaller steps when carrying a heavy backpack to avoid high impact forces at the knees and leg joints.

    Never underestimate how extreme temperatures in the workplace impact the body’s ability to function at its best, either, says Professor of Kinesiology Stephen Cheung.

    He says hot environments add heat stress to bodies that are already generating a lot of heat.

    “Research has also shown that productivity decreases and errors such as risky behaviour, inattention and difficulty in decision making increase over multiple days of heat exposure, such as what may occur during a heat wave,” says Cheung.

    A similar dynamic of decreased productivity and risk of accidents occurs in cold environments, he says.

    “Muscles have a harder time functioning, and the risks for musculoskeletal injuries may increase due to muscles being stiffer,” says Cheung. “Furthermore, cold hands reduce dexterity in performing fine movements, inhibiting the ability to perform simple manufacturing tasks through to performing critical tasks in an emergency situation.”

  • How to plan an accessible, educational night of Halloween fun

    EXPERT ADVISORY – October 28, 2024 – R0128

    Brock University experts are providing tips to make Halloween accessible, healthy and educational for all trick-or-treaters.

    “Twenty-two per cent of Canadians identify as neurodiverse or disabled in some way, so if you extrapolate that, one in five kids coming to your house will likely fall under that umbrella,” says Professor of Physical Education and Kinesiology Maureen Connolly.

    Also the Director of Research at the Brock-Niagara Centre of Excellence in Inclusive and Adaptive Physical Activity, Connolly says anticipating “complexity and diversity” and planning festivities with inclusion in mind ensures no one — children going door-to-door or the caregivers accompanying them — feels left out on Oct. 31.

    Connolly says it’s still possible to enjoy the thrills associated with creating spooky environments without endangering the safety or enjoyment of treat-seekers.

    “The startle reflex is significant for anyone managing spasticity, for instance, so offering fair warning to anyone approaching your property, such as a sign that indicates there may be sudden loud noises, can alert people to any potential triggers and avoid potential injury,” she says.

    Planning with “open minds and open hearts” can help make Halloween an accessible experience, with Connolly suggesting treat-givers:

    • Have options for trick-or-treating stations and set up in an accessible location, like the end of the driveway, to reduce obstacles and accommodate children who aren’t comfortable around crowds or noise.
    • Provide treats free from common allergens and/or in packaging that lists the ingredients for children with dietary restrictions. Non-food treats are also an option.
    • Understand that some children may not use speech as a communication method and that not getting a verbal response doesn’t mean they are ungrateful. Smiles and waves are widely understood forms of communication. Try to avoid ignoring a child in favour of speaking solely to the parent.
    • Involve those participating at home by having them give out treats and interact with treat-seekers of the same age.

    Once the trick-or-treating is done, Assistant Professor of Early Childhood Education Jamie Barratt says it’s important to consider how increased sugar consumption can impact children’s behaviour and learning.

    “Sugar highs and crashes can make it harder for children to focus and engage in school activities following the holiday, so it’s important to encourage balance and discuss moderation while still encouraging them to enjoy Halloween,” she says.

    Barratt says parents can do so by engaging in discussions about moderation and balancing their children’s sugar intake with nutritious snacks such as fruit, nuts, seeds or protein-rich foods throughout the day.

    Professor of Health Sciences Jason Liu also encourages parents to monitor the amount of Halloween candy children eat, since early lifestyle changes could help prevent or mitigate chronic diseases.

    “Halloween’s a good time to teach your kids how to control the amount of candy they eat and develop self-discipline in this area,” says Liu, who studies cardiovascular disease and its related risk factors. “Diet plays a very important role in children’s growth and building a strong immune system.”

    He says poor diets are associated with a poor cardiometabolic profile in early childhood, which may cause insulin resistance and contribute to cardiovascular risk in adulthood. Childhood overconsumption of saturated fats and carbohydrates also contributes to obesity and heart disfunction, while an overconsumption of sugar triggers inflammation, damaging the blood circulation system and contributing to the progress of atherosclerosis. It may also interfere with children’s sleep patterns, which can fuel obesity.

    The candy haul itself can also prompt conversations about future thinking to help children develop related skills, says Professor of Psychology Caitlin Mahy.

    “Any time children are presented with an abundance of resources all at once, it’s a good opportunity to start a conversation about future and current needs,” she says. “Children can think about saving and allotting candy over time to extend their enjoyment of it. They can also start developing empathy for their future self, making choices on how much candy they eat so they, for example, don’t get a stomach ache.”

    To help children develop future-thinking skills in an age-appropriate way, Mahy suggests parents:

    • Use shorter future-thinking time frames for younger children. For a three- or four-year-old, talk about tomorrow or the day after tomorrow, she says, whereas a child closer to eight or 10 can think about next week or next month.
    • Start conversations with open-ended questions that prompt kids to consider how they’ll manage resources over time, such as: Are you going to make piles? How much candy would you like to have left tomorrow/next week/in a month?
    • Talk about future consequences but avoid getting discouraged if a child wants to eat all the candy right away, as young kids are centred in the present.
