Ben’s is a physiotherapist and post-doctoral researcher from Jyväskylä, Finland. His recent PhD thesis investigated the effected the effect of aquatic resistance training on the biochemical composition of tibiofemoral cartilage, body composition and function in women with mild knee osteoarthritis. Additionally, he focused on investigating the effect of aquatic exercise on functional capacity at different stage of the osteoarthritis continuum.


Ben’s post-doctoral studies are focused on investigating the acute effect of immersion in water and aquatic exercise on the neuromuscular system in both healthy adults and different patient populations. Measuring the response of the neuromuscular system during immersion is notoriously difficult. However, Ben and colleagues are developing innovative methods that will allow a deeper understanding of what happens during immersion e.g. ultrasound imaging of muscle and soft tissue architecture. Thus, the results will guide the development and optimal prescription of aquatic therapy in the future.


Ben’s established his own aquatic therapy service in his adopted home town of Jyväskylä, Finland. This service provides high-level aquatic therapy treatments to a wide range of patient groups including some of Finland’s top athletes from all sports as well as developing a service for people suffering from chronic pain. Ben also worked a physiotherapist for the Finnish Swimming Federation and the local swimming team for over ten years and is also a recognized educator in different aquatic therapy techniques.
