Originally designed to mitigate skull fractures and traumatic brain injuries in hockey players, hockey helmets have now become a critical focus for further research due to the rise in mild traumatic brain injuries. With the sport's evolution introducing stronger and faster players, new approaches that incorporate facial shielding in helmet technolo...
Transtibial amputation (TTA) is the removal of the lower leg often resulting in pain, mental health issues, and a more sedentary lifestyle that lacks physical activity (PA). Low balance confidence and other factors related to the physical and psychosocial adaptation to amputation could contribute to why people with TTA actively avoid PA. Studies ha...
Dry cupping is a therapeutic modality proposed to produce a negative pressure, stretching the skin and underlying tissue. This mechanism is said to promote regional blood flow of oxygenated blood and causing a physiological stretch in the tissue, allowing it to elongate and potentially changing skin temperature. The possible effects of the applicat...

Boxing headguards offer a form of head protection to minimize the risk of head injuries for athletes. Existing literature, however, lacks information regarding the protective capabilities of boxing headguards. This study examined the protective capacity of three boxing headguards in minimizing impact accelerations to the head that cause concussions...
Postmenopausal osteoporosis is a serious concern in aging individuals, but has not been explored for its potential to alter the shape of the inner ear by way of increased remodeling in the otic capsule. The otic capsule, or bony labyrinth, is thought to experience uniquely limited remodeling after development due to high levels of osteoprotegerin....
The risk of concussions in ice hockey is high despite use of vinyl-nitrile (VN) and expanded polypropylene (EPP) materials in helmet liners. Linings made of thermoplastic polyurethane (TPU) seem to offer better mitigation of impact accelerations. The first purpose of this study was to compare the use of TPU linings to VN and EPP liners on measures...

A traumatic brain injury reflects a heterogeneous description. The mildest form has been referred to as that of a concussion, with recent steps being taken to reclassify this as mild traumatic brain injury (mTBI). Management has developed in tandem with the understanding of what mTBI, as have methods that physiotherapists (PTs) may use to provide c...
Hockey helmets represent the best form of head protection available to reduce the occurrence of skull fracture and concussion. Currently, helmet testing protocols focus on the reduction of peak linear acceleration measures. Gaps exist in analyzing how certain impact factors such as angle, neck stiffness, and location influence the energy loaded to...
Tai chi is effective for improving the postural stability of older adults, but the effects on healthy young adults has yet to be investigated. Currently, the use of virtual delivery platforms for various exercise prescriptions to patients has had to be quickly introduced related to the onset of the COVID-19 pandemic and physical distancing requirem...
Due to the repetitive high forces and torques placed on an individual during a baseball pitch, shoulder pain is present in 46-57% of pitchers.

Thirty-nine healthy, active individuals completed a modified agility task under the three brace condi...
It has been proposed that during running, the greatest force occurs when the foot strikes the ground and simultaneously exhalation occurs at initial heel contact. As a result, breathing retraining has been used as a method to prevent lower extremity overuse injuries by modifying an individual's breathing pattern and consequently, reducing ground re...
The danger and risk associated with ice hockey has led to the development of new helmet technologies and testing protocols to minimize the risk of traumatic brain injuries or concussions.

International Journal of Exercise Science 12(1): 15-23, 2019. Ankle braces have been hypothesized to prevent ankle injuries by restricting range of motion (ROM) and improving proprioception at the ankle. As such, ankle braces are commonly worn by physically active individuals to prevent ankle injuries. Despite their widespread use, the effects that...
Ankle braces are often worn to prevent ankle injuries. Evidence supports their ability to prevent ankle injuries; however, the effects that ankle braces have on proximal biomechanics and injuries is unclear. This pilot study explored the effects of ankle braces on lower extremity electromyographic (EMG) activity and vertical ground reaction force (...
