Graston Technique Pressure Changes On Hamstring Range Of Motion, Emily Martz Apr 2018

Graston Technique Pressure Changes On Hamstring Range Of Motion, Emily Martz

Theses and Dissertations

Context: Instrument assisted soft tissue mobilization (IASTM) can be applied as a myofascial treatment using a set of instruments and is growing in popularity with clinicians. There is a gap in the literature identifying the best pressure application recommendation without eliciting unnecessary discomfort.

Objective: To investigate if using light or firm pressure applied with the Graston Technique (GT) would have an impact on changing range of motion (ROM).

Design: Single blinded randomized control trial

Setting: Laboratory

Patients or Other Participants: Twenty-seven physically active participants (14 females and 13 males; age: 23±3.4 years; height: 68.59±3.32; weight ...


Effects Of Controlled-Whole Body Vibration Training On Reducing Risk Of Falls In People With Multiple Sclerosis, Maria Cristal Sanchez Jan 2016

Effects Of Controlled-Whole Body Vibration Training On Reducing Risk Of Falls In People With Multiple Sclerosis, Maria Cristal Sanchez

Open Access Theses & Dissertations

Falls present a serious challenge among people affected by multiple sclerosis (MS). Controlled whole-body vibration (CWBV) training has been recently introduced into the physical therapy field to prevent falls in older adults. The purpose of this study was to examine the effects of an 8-week vibration-training program in reducing the risk of falls in people living with MS. The study adopted a single-group pre-test â?? post-test longitudinal design. Twenty-five adults with clinicallyâ??confirmed MS were enrolled in this study to undergo the 8-week intervention on a side-alternating vibration machine. The training was delivered three times a week for eight weeks ...


The Effects Of A Foot-Toe Orthosis On Dynamic Balance And Hallux Valgus Angle, Adam Richard Kelly Apr 2014

The Effects Of A Foot-Toe Orthosis On Dynamic Balance And Hallux Valgus Angle, Adam Richard Kelly

Theses and Dissertations

Context: Decreased balance has been identified as a risk factor for lower extremity injury in several populations. Previous literature has investigated the effects of using orthotics, textured insoles and textured surfaces on balance. However, no research exists on the effects of a foot-toe orthosis on dynamic balance. Objective: To determine the effects of a foot-toe orthosis on dynamic balance and hallux valgus angle. Design: A randomized controlled trial. Setting: Athletic Training research laboratory. Participants: Sixty-three healthy and recreationally active collegiate students. (age: 21.59±1.49yrs, height 172.48±8.99cm, mass 73.86kg±15.64kg) Interventions: Participants were randomly ...


The Effects Of Static Stretching Versus Dynamic Stretching On Lower Extremity Joint Range Of Motion, Static Balance, And Dynamic Balance, Wenqing Wang Aug 2013

The Effects Of Static Stretching Versus Dynamic Stretching On Lower Extremity Joint Range Of Motion, Static Balance, And Dynamic Balance, Wenqing Wang

Theses and Dissertations

The purpose of this study was to examine the effects of static stretching (SS) versus dynamic stretching (SS) on lower extremity joint range of motion (ROM), static balance, and dynamic balance. Fifteen active subjects with tight hamstring and calf muscles participated. Hip flexion and knee extension ROM angle was measured using a fluid inclinometer. A closed-chain method of measuring ankle dorsiflexion ROM was used. Static balance was assessed in single-leg stance on a force plate using the time-to-boundary (TTB) measurement. The Star Excursion Balance Test (SEBT) was used to assess dynamic balance in three directions. These measurements were assessed before ...


Biomechanical Comparison Of Titanium And Cobalt Chromium Pedicle Screw Rods In An Unstable Cadaveric Lumbar Spine, James Doulgeris Jan 2013

Biomechanical Comparison Of Titanium And Cobalt Chromium Pedicle Screw Rods In An Unstable Cadaveric Lumbar Spine, James Doulgeris

Graduate Theses and Dissertations

Pedicle screw-rod instrumentation is considered a standard treatment for spinal instability, and titanium is the most common material for this application. Cobalt-chromium has several advantages over titanium and is generating interest in orthopedic practice. The aim of this study was to compare titanium versus cobalt-chromium rods in posterior fusion, with and without transverse connectors, through in vitro biomechanical testing and determine the optimal configuration.

Six cadaveric lumbar spines (L1-S1) were used. Posterior and middle column injuries were simulated at L3-L5 and different pedicle screw constructs were implanted. Specimens were subjected to flexibility tests and range of motion, intradiscal pressure and ...


Consequence Of Functioning At The End Range Of Joint Motion: Implications On Anterior Knee Pain, Pedro A. Rodrigues May 2011

Consequence Of Functioning At The End Range Of Joint Motion: Implications On Anterior Knee Pain, Pedro A. Rodrigues

Open Access Dissertations

“Excessive” and/or “delayed” subtalar joint (STJ) pronation has been linked to overuse injuries because of its influence on tibial internal rotation (TIR). The transfer of STJ pronation to TIR occurs via the talocrual joint, believed to have limited transverse plane motion. However, studies have shown the talocrural joint to have more transverse plane motion than once believed, therefore it is feasible that the STJ will only influence the motion of the tibia once this motion has been exhausted.

Currently, studies evaluating this relationship have focused on peak joint angles and excursion without reference to the amount of motion available ...
