Following stroke, the brain undergoes various stages of recovery where the central nervous system can reorganize neural circuitry (neuroplasticity) both spontaneously and with the aid of behavioral rehabilitation and non-invasive brain stimulation. Multiple neuroimaging techniques can characterize common structural and functional stroke-related deficits, and importantly, help predict recovery of function. Diffusion tensor imaging (DTI) typically reveals increased overall diffusivity throughout the brain following stroke, and is capable of indexing the extent of white matter damage. Magnetic resonance spectroscopy (MRS) provides an index of metabolic changes in surviving neural tissue after stroke, serving as a marker of brain function. The neural …

Second, six different MDT raters were recruited to rate 53 selected vignettes and reliability was determined using Fleiss Kappa. Results: There was “substantial agreement” among six MDT raters …
A Randomized Clinical Trial To Compare The Effect Of Non Operative Treatment With And Without Autologous Conditioned Plasma (Acp) On Healing And Function In Patients With Achilles Tendon Ruptures, Tyler M. Pratt
Electronic Thesis and Dissertation Repository
The purpose of this study was to determine whether there is evidence to support conducting a larger randomized control trial (RCT) to compare the non-operative treatment of Achilles tendon (AT) ruptures with or without Autologous Conditioned Plasma (ACP®). Twenty-four patients were randomized to receive an ACP® or saline injection within seven days and again at two weeks post-rupture. Tendon healing was longitudinally evaluated using ultrasound (US) and magnetic resonance imaging (MRI). Functional and patient-reported quality of life measures were also assessed. A small sample size limited our ability to detect statistically significant differences. The mean rankings of healing were slightly …

Stability Study: A Multicentre Rct Comparing Acl Reconstruction With And Without Lateral Extra-Articular Tenodesis For Individuals At High Risk Of Graft Failure, Christopher Eric Hewison
Electronic Thesis and Dissertation Repository
Seventy patients undergoing anterior cruciate ligament (ACL) reconstruction (ACLR) were randomly assigned to receive ACLR alone or ACLR plus a lateral extra-articular tenodesis (LET). Our primary outcome was Limb Symmetry Index (LSI) calculated using a series of four hop tests at six months postoperative. Secondary outcomes measures included pain, subjective function and isokinetic strength testing. We found no statistically significant difference between the two groups in LSI calculations. We found statistically significant differences favouring the ACLR alone group in quadriceps average power and peak torque symmetry measurements at six-months postoperative when we adjusted for baseline measurements. No other statistically significant …

The Association Between Soft Tissue Releases And Bony Resections Performed During Total Knee Arthroplasty And Patients' Pain And Satisfaction Postoperatively, Matt Carter
Electronic Thesis and Dissertation Repository
Total knee arthroplasty (TKA) is a surgical treatment of degenerative knee conditions such as osteoarthritis to reduce pain and increase function. Intraoperative soft tissue releases (STRs) and bony resections (BRs) are necessary for a balanced and aligned TKA. It is possible that the degree of STRs and BRs is related to final outcome following TKA and thus there may be implications for patient rehabilitation, patient expectations, pain medications, and timelines for recovery. Thus, our primary objective was to examine the association between the number of STRs and BRs performed intraoperatively and patients’ satisfaction and pain at three months. We performed …

Ultrasound Guided Motor Sparing Knee Blocks For Postoperative Analgesia Following Total Knee Arthroplasty, Olawale A. Sogbein
Electronic Thesis and Dissertation Repository
Postoperative total knee arthroplasty (TKA) pain is severe and can inhibit patients’ rehabilitation. We devised a single injection motor sparing knee block (MSB) by targeting the adductor canal and lateral femoral cutaneous nerve with a posterior knee infiltration under ultrasound. Our primary objective was to evaluate the duration of the MSB compared to a standard periarticular infiltration (PAI) using time to first rescue analgesia as the end point. We randomized 82 patients undergoing TKA to receive either preoperative MSB or intraoperative periarticular infiltration. Duration of analgesia was significantly longer in the MSB group with a mean difference of 8.8 hours. …
Predictors Of Appropriate Referral To Total Knee Arthroplasty: A Validation Study, Samuel J. Malian
Predictors Of Appropriate Referral To Total Knee Arthroplasty: A Validation Study, Samuel J. Malian
Electronic Thesis and Dissertation Repository
Approximately 45% of referrals from primary care physicians to arthroplasty surgeons are inappropriate. Currently, Canadians are waiting over three months for consultation with an arthroplasty surgeon. Reducing the proportion of inappropriate referrals will reduce the wait time to first consultation with an arthroplasty surgeon. This study’s objective was to validate a model that identified patient-reported predictors of appropriate referrals to arthroplasty. We screened 258 patients attending their first consultation with an arthroplasty surgeon. Participants completed the questionnaires prior to their appointment and the surgeon detailed each consultation outcome on a standardized form. We constructed our validation model using the same …
A Prospective Cohort Study Investigating Functional Recovery In Patients With Osteoarthritis Following Total Hip Arthroplasty Using A Direct Anterior Versus Direct Lateral Surgical Approach, Bryn O. Zomar
Electronic Thesis and Dissertation Repository
We used a quasi-randomized cohort study to investigate whether there are differences in early functional recovery between patients who undergo total hip arthroplasty using a direct anterior (DA) or direct lateral (DL) surgical approach. We found significant differences in favour of the DA group for many functional outcomes including: gait velocity, stride length, operative limb single-limb support, single-limb support symmetry and time to complete the Timed Up and Go. Our primary outcome, gait velocity, was significantly greater in the DA group at discharge, two weeks and six weeks postoperative with adjusted mean differences of 0.12m/s, 0.15m/s and 0.17m/s respectively. There …

Take 2 Steps And Call Me In The Morning: Prescribing Physical Activity Through Primary Care, Emily Knight
Take 2 Steps And Call Me In The Morning: Prescribing Physical Activity Through Primary Care, Emily Knight
Electronic Thesis and Dissertation Repository
Objectives: Physical activity guidelines for older adults target high-intensity activities (i.e. increasing exercise), with less attention on low-intensity activities (i.e. reducing/interrupting sedentary behaviours) to improve health. Mobile health (mHealth) holds promise for engaging patients in self-management of chronic diseases. The purpose of this research was to prescribe physical activity of various intensities (i.e. sedentary through exercise) in primary care paired with mHealth for self-management.
Methods: 60 older adults (55-75yr) were randomly assigned to four groups: one control, and three receiving mHealth kits plus prescription for a specific intensity of physical activity (exercise, sedentary or both). Clinical measures (anthropometrics, …

Characterizing Knee Loading Patterns In People Post-Stroke, Stephanie Marrocco
Electronic Thesis and Dissertation Repository
Post-stroke temporal gait asymmetry (TGA) could cause excess loading of the non-paretic leg which may cause musculoskeletal (MSK) issues in the knee. This thesis investigated knee loading during gait and its relationship to TGA post-stroke. Methods: Gait analysis was conducted in nine people post-stroke. Gait was classified as symmetric (TGS) or asymmetric and external knee adduction (KAM) and flexion moments (KFM) were calculated. Participants were compared to healthy older adults (n=109) on KAM and KFM. The proportion of individuals with increased loading was compared between the TGS and TGA groups. Results: Six and four participants exhibited increased loading …
Mirror Therapy For The Lower-Extremities Post-Stroke, Lucas David Crosby
Mirror Therapy For The Lower-Extremities Post-Stroke, Lucas David Crosby
Electronic Thesis and Dissertation Repository
Despite extensive rehabilitation post-stroke gait remains slow, variable and asymmetric. There is a need for simple interventions to improve lower-extremity motor control and walking ability. Mirror therapy is a promising intervention though little attention has focused on its use on the lower-extremities post-stroke. This thesis investigates the feasibility and potential effects of a bilateral lower-extremity mirror therapy intervention (LE-MT) post-stroke. A case series involving three participants, who performed twelve 30 minute sessions of LE-MT over four weeks, is presented. Session duration and number of repetitions completed improved over the course of the intervention indicating LE-MT post-stroke is feasible. Some cases …
