Ten minutes ergometer rowing exercise increases pressure pain thresholds in high performance rowers

Background: Mechanical hypoalgesia has been demonstrated following bouts of acute exercise. The pain relieving properties of exercise thus have the potential to be utilised to help manage painful musculoskeletal conditions, such as osteoarthritis. The mechanisms that underlie this exercise - induced hypoalgesia are poorly understood; as is the type of exercise, the duration and the intensity required to produce hypoalgesia. A complete knowledge of these factors is required before therapeutic exercise programs for pain management can be implemented on an evidence basis in the clinical setting. This research provides a clearly defined exercise protocol which induces hypoalgesia. Hypothesis: Ten minutes ergometer rowing increases pressure pain thresholds in high performance rowers. Study design: Laboratory Study, within - group repeated measures Methods: 20 high performance rowers (13M:7F; mean age: 20.8 years ± 1.74) had pressure pain threshold measurements performed at three anatomical sites (2 local, 1 remote) before and immediately following 10 minutes ergometer rowing at 50-80% estimated VO2max. Results: Pressure pain thresholds were significantly increased (P < 0.05) at all anatomical locations post - exercise compared to pre - exercise. Conclusions: High intensity ergometer rowing induces statistically and clinically significant mechanical hypoalgesia at both local and remote sites in high performance rowers. Clinical relevance: Ergometer rowing is a low impact activity that may prove beneficial in the management of painful joint and muscle conditions, such as osteoarthritis

Functional performance of a bi-layered chitosan-nano-hydroxyapatite osteochondral scaffold: a pre-clinical <i>in vitro</i> tribological study

Osteochondral grafts are used for repair of focal osteochondral lesions. Autologous grafts are the gold standard treatment; however, limited graft availability and donor site morbidity restrict use. Therefore, there is a clinical need for different graft sources/materials which replicate natural cartilage function. Chitosan has been proposed for this application. The aim of this study was to assess the biomechanics and biotribology of a bioresorbable chitosan/chitosan-nano-hydroxyapatite osteochondral construct (OCC), implanted in an in vitro porcine knee experimental simulation model. The OCC implanted in different surgical positions (flush, proud and inverted) was compared to predicate grafts in current clinical use and a positive control consisting of a stainless steel graft implanted proud of the cartilage surface. After 3 h (10 800 cycles) wear simulation under a walking gait, subsidence occurred in all OCC samples irrespective of surgical positioning, but with no apparent loss of material and low meniscus wear. Half the predicate grafts exhibited delamination and scratching of the cartilage surfaces. No graft subsidence occurred in the positive controls but wear and deformation of the meniscus were apparent. Implanting a new chitosan-based OCC either optimally (flush), inverted or proud of the cartilage surface resulted in minimal wear, damage and deformation of the meniscus

The prevalence and factors associated with knee pain in Great Britain's Olympians aged 40 years and older.

Purpose: affecting approximately one in four adults over the age of 40 years in the UK, knee pain is the most common presenting feature of osteoarthritis (OA). Despite the plethora of studies that have investigated the factors associated with the onset of knee pain in the sedentary population, relatively little is known about the prevalence and occupational factors associated with knee pain in an athletic sporting population. This study aimed to determine in Great Britain’s (GB) Olympians, aged 40 years and older, (1) the individual factors
