Cross slope gait biomechanics for individuals with and without a unilateral transtibial amputation.

Background: This research was conducted to better understand compensatory strategies during cross-slope walking for adults with and without a unilateral transtibial amputation.

Methods: Fourteen individuals with unilateral transtibial amputation and 14 individuals with no lower limb amputation participated in this study. Motion and force data were captured while participants walked on a treadmill in a virtual reality environment for level and ± 5° cross slopes.

Mitigating Long-Term COVID-19 Consequences on Brain Health.

COVID-19 is increasingly being linked to brain health impacts. The emerging situation is consistent with evidence of immunological injury to the brain, which has been described as a resulting "brain fog." The situation need not be medicalized but rather clinically managed in terms of improving resilience for an over-stressed nervous system.

Out of the shadows: Chronic pain in Canadian Armed Forces veterans - Proceedings of a workshop at the 2019 Forum of the Canadian Institute for Military and Veteran Health Research.

This commentary summarizes proceedings of a workshop on chronic pain in military personnel and veterans (released personnel) at the Annual Forum of the Canadian Institute for Military and Veteran Health Research in Gatineau and Ottawa on October 22, 2019. The extent and impact of chronic pain among Canadian Armed Forces (CAF) veterans and their families is significant and has been underappreciated, largely due to limited disclosure by serving and veteran military personnel, stemming from a fear of stigmatization. Living with pain is seen as a fact of life in military cultures, something to be endured and not discussed.

A Decade of mTBI Experience: What Have We Learned? A Summary of Proceedings From a NATO Lecture Series on Military mTBI.

Mild traumatic brain injury (mTBI, also known as a concussion) as a consequence of battlefield blast exposure or blunt force trauma has been of increasing concern to militaries during recent conflicts. This concern is due to the frequency of exposure to improvised explosive devices for forces engaged in operations both in Iraq and Afghanistan coupled with the recognition that mTBI may go unreported or undetected. Blasts can lead to mTBI through a variety of mechanisms.

Comparing the Efficiency of Software-Based Speech Recognition Versus Traditional Telephone Transcription in an Outpatient Physical Medicine and Rehabilitation Practice.

Introduction: Speech recognition (SR) uses computerized word recognition software that automatically transcribes spoken words to written text. Some studies indicate that SR may improve efficiency of electronic charting as well as associated cost and turnaround time1,2, but it remains unclear in the literature whether SR is superior to traditional transcription (TT). This study compared the impact of report generation efficiency of SR to TT at the Canadian Armed Forces Health Services Centre.

Maintaining stable transtibial amputee gait on level and simulated uneven conditions in a virtual environment.

Purpose: This research compares gait strategies to maintain stable gait over a variety of non-level walking conditions for individuals with a transtibial amputation and able-bodied individuals.

Methods: Twelve people with unilateral transtibial amputation and twelve able-bodied individuals walked on a self-paced treadmill in a park-like virtual environment with level and continuous perturbation conditions. Walking stability was quantified by margin-of-stability, step parameters (walking speed, temporal and spatial parameters, and foot clearance), and gait variability (standard deviations for margin-of-stability, step parameters, and root-mean-square of trunk acceleration).

Reflections on recovery, rehabilitation and reintegration of injured service members and veterans from a bio-psychosocial-spiritual perspective.

Medical interventions regarding trauma resuscitation have increased survivorship to levels not previously attained. Multiple examples from recent conflicts illustrate the potential return to high-level function of severely injured service members following medical and rehabilitative interventions. This review addresses the goals of rehabilitation, distills hard-won lessons of the last decade of military trauma and rehabilitation, and recommends the use of a bio-psychosocial-spiritual approach to care that can be applied at all tiers of the health care system.

Gait differences between K3 and K4 persons with transfemoral amputation across level and non-level walking conditions.

Background:: A transfemoral amputee's functional level can be classified from K-level 0 (lowest) to K-level 4 (highest). Knowledge of the biomechanical differences between K3 and K4 transfemoral amputation could help inform clinical professionals and researchers in amputee care and gait assessment.

Objectives:: Explore gait differences between K3- and K4-level transfemoral amputation across different surface conditions.

Maintaining stable transfemoral amputee gait on level, sloped and simulated uneven conditions in a virtual environment.

Purpose: Describe and quantify how people with transfemoral amputations (TFA) maintain stable gait over a variety of surfaces; including, downhill and uphill, top and bottom-cross-slopes, medial-lateral translations, rolling hills and simulated rocky surfaces.

Methods: Ten TFA and ten matched people without amputations (NA) walked in a virtual environment with level, sloped and simulated uneven surfaces on a self-paced treadmill. Stability was quantified using medial-lateral margin of stability (ML-MoS), step parameters, and gait variability (standard deviations for speed, temporal-spatial parameters, foot clearance and root-mean-square of medial-lateral trunk acceleration).

Antibiotics in the treatment of patients with lower back pain associated with Modic changes: a case series.

Purpose: To determine the clinical effect of antibiotic treatment for patients with low back pain and Modic 1 changes.

Methods: This is a retrospective case series of patients treated at the Canadian Forces Health Services Centre in Ottawa and the McGill University Health Centre. Where available, pain, functional, and imaging outcomes in 11 patients treated between 2013 and 2015 were analyzed to determine effect of antibiotic treatment for patients with low back pain and associated Modic 1 changes on magnetic resonance imaging.

Effectiveness of Service Dogs for Veterans with PTSD: Preliminary Outcomes.

Limited scientific evidence on the effectiveness of psychiatric service dogs used by Veterans with post-traumatic stress disorder (PTSD) is available. This study investigated their short-term effectiveness among 15 Canadian veterans who received a first psychiatric service dog. Preliminary results suggest potential beneficial effects at 3 months on the psychiatric symptoms.

A randomized comparison between neurostimulation and ultrasound-guided lateral femoral cutaneous nerve block.

Background: This prospective, randomized trial compared neurostimulation (NS) and ultrasound (US) guided lateral femoral cutaneous nerve (LFCN) block. We hypothesized that US would result in a shorter total anesthesia-related time (sum of performance and onset times).

Methods: Twenty-one volunteers were enrolled.

Changes to transtibial amputee gait with a weighted backpack on multiple surfaces.

Background: Modern prosthetic technology and rehabilitation practices have enabled people with lower extremity amputations to participate in almost all occupations and physical activities. Carrying backpack loads can be an essential component for many of these jobs and activities; however, amputee gait with backpack loads is poorly understood. This knowledge gap must be addressed in order to further improve an individual's quality of living through changes in rehabilitation programs and prosthesis development.

Center of pressure and total force analyses for amputees walking with a backpack load over four surfaces.

Understanding how load carriage affects walking is important for people with a lower extremity amputation who may use different strategies to accommodate to the additional weight. Nine unilateral traumatic transtibial amputees (K4-level) walked over four surfaces (level-ground, uneven ground, incline, decline) with and without a 24.5 kg backpack.

Diabetic Cranio-Cervico-Radiculoplexus Neuropathy.

We describe a case of a 53-year-old man with type 2 diabetes mellitus in whom cervical-radiculoplexus neuropathy developed, with concomitant cranial and phrenic nerve involvement, occurring as a stepwise, monophasic course. The patient had a presumed remote history of idiopathic cervical-radiculoplexus neuropathy.

Fixed and self-paced treadmill walking for able-bodied and transtibial amputees in a multi-terrain virtual environment.

A self-paced treadmill automatically adjusts speed in real-time to match the user's walking speed, potentially enabling more natural gait than fixed-speed treadmills. This research examined walking speed changes for able-bodied and transtibial amputee populations on a self-paced treadmill in a multi-terrain virtual environment and examined gait differences between fixed and self-paced treadmill speed conditions. Twelve able-bodied (AB) individuals and 12 individuals with unilateral transtibial amputation (TT) walked in a park-like virtual environment with level, slopes, and simulated uneven terrain scenarios.

Going places: Does the two-minute walk test predict the six-minute walk test in lower extremity amputees?

Objective: Assessing a patient's ability to walk the distance required for community ambulation (at least 300 m) is important in amputee rehabilitation. During the 2-min walk test, most amputees cannot walk 300 m. Thus, the 6-min walk test may be preferred, but it has not been fully validated in this population.

Disability correlates in Canadian Armed Forces Regular Force Veterans.

Purpose: This study was undertaken to inform disability mitigation for military veterans by identifying personal, environmental, and health factors associated with activity limitations.

Method: A sample of 3154 Canadian Armed Forces Regular Force Veterans who were released during 1998-2007 participated in the 2010 Survey on Transition to Civilian Life. Associations between personal and environmental factors, health conditions and activity limitations were explored using ordinal logistic regression.

Radiofrequency denervation of the hip joint for pain management: case report and literature review.

Background: A 55-year-old male presented with severe pain and functional limitations as a result of left hip osteoarthritis. He had failed multiple treatments while waiting for a hip arthroplasty, including physical therapy, medications, and various intra-articular injections. Thermal radiofrequency lesioning of the obturator and femoral articular branches to the hip joint was offered in the interim.

Changes to level ground transtibial amputee gait with a weighted backpack.

Background: Many occupations and hobbies require the use of a weighted pack. To date there has been limited backpack gait studies performed on the amputee population. It is important that we address this knowledge gap in order to further improve individual's quality of living through changes in rehabilitation, and prosthesis development.

Physical rehabilitation following polytrauma. The Canadian Forces Physical Rehabilitation Program 2008-2011.

As a consequence of Canada's involvement in the war in Afghanistan, many members of the Canadian Forces have experienced debilitating injuries. Despite the Canadian Forces Health Services (CFHS) having outstanding relationships with many civilian care providers for the rehabilitation of injured soldiers, it became apparent early on that the high-level goals and aspirations of these returning soldiers were sometimes beyond the capability of these centres to facilitate. From this reality grew the need to develop a Physical Rehabilitation Program within the CFHS.
