A Multiple Degree Of Freedom Lower Extremity Isometric Device To Simultaneously Quantify Hip, Knee, And Ankle Torques, Natalia Sánchez, Ana Maria Acosta, Arno H. A. Stienen, Julius P. A. Dewald

Physical Therapy Faculty Articles and Research

Characterization of the joint torque coupling strategies used in the lower extremity to generate maximal and submaximal levels of torque at either the hip, knee, or ankle is lacking. Currently, there are no available isometric devices that quantify all concurrent joint torques in the hip, knee, and ankle of a single leg during maximum voluntary torque generation. Thus, joint-torque coupling strategies in the hip, knee, and concurrent torques at ankle and/or coupling patterns at the hip and knee driven by the ankle have yet to be quantified. This manuscript describes the design, implementation, and validation of a multiple degree of …

Identification Of Functional Parameters For The Classification Of Older Female Fallers And Prediction Of ‘First-Time’ Fallers, Niklas König Ignasiak

Physical Therapy Faculty Articles and Research

Falls remain a challenge for ageing societies. Strong evidence indicates that a previous fall is the strongest single screening indicator for a subsequent fall and the need for assessing fall risk without accounting for fall history is therefore imperative. Testing in three functional domains (using a total 92 measures) were completed in 84 older women (60–85 years of age), including muscular control, standing balance, and mean and variability of gait. Participants were retrospectively classified as fallers (n = 38) or non-fallers (n = 42) and additionally in a prospective manner to identify first-time fallers (FTFs) (n = 6) within a …

Quantitative Ultrasound: Measurement Considerations For The Assessment Of Muscular Dystrophy And Sarcopenia, Michael O. Harris-Love, Reza Monfaredi, Catheeja Ismail, Marc R. Blackman, Kevin Cleary

Exercise and Nutrition Sciences Faculty Publications

Diagnostic musculoskeletal ultrasound has potential clinical utility in characterizing pathological muscle tissue. Sonography has been long proposed as method of assessing muscle damage due to neuromuscular diseases such as muscular dystrophy, and more recently, changes in body and tissue composition associated with muscle wasting disorders such as sarcopenia. The use of quantitative ultrasound as an adjunct diagnostic procedure has different technical challenges than the traditional use of ultrasound in clinical medicine. Operator-dependent technique and variation are critical considerations when obtaining measures of echointensity (i.e., tissue composition estimates) and tissue dimensions (i.e., muscle thickness) – key elements of the ultrasound assessment …

Reliability Of Two Alternative Methods For The Standard Mid-Thigh Isometric Pull, Duane A. Williams, Courtney D. Hall, Patsy Cantor, Jennifer Williams, N. Brown, Ryan Dulling, Ogechi Egbujor

ETSU Faculty Works

The purpose of this study was to determine the reliability of two new alternative portable methods for measuring maximal isometric force measures while performing the standard mid-thigh pull. One method, the bar grip method, required the use of the trunk and upper extremity muscles, while the second method, the pelvic belt method, did not. Both methods demonstrated good test-retest reliability via randomized repeated measures over 24-36 hours. Interestingly, the pelvic belt method generally demonstrated average maximal forces up to 65% higher than the bar method. There was a good relationship between both methods. These new alternative methods could provide strength …

Publications and Research

The objective of this study was to assess changes in corticospinal excitability and spinal output following noninvasive transpinal and transcortical stimulation in humans. The size of the motor evoked potentials (MEPs), induced by transcranial magnetic stimulation (TMS) and recorded from the right plantar flexor and extensor muscles, was assessed following transcutaneous electric stimulation of the spine (tsESS) over the thoracolumbar region at conditioning-test (C-T) intervals that ranged from negative 50 to positive 50 ms. The size of the transpinal evoked potentials (TEPs), induced by tsESS and recorded from the right and left plantar flexor and extensor muscles, was assessed following …

Mechanisms Of Isometric Exercise-Induced Hypoalgesia In Young And Older Adults, Kathy J. Lemley

Dissertations (1934 -)

Pain reduction following exercise (exercise-induced hypoalgesia; EIH) is well-established in young adults. Specific to isometric exercise, the greatest EIH follows low intensity contractions held for long duration. The EIH response of older adults is not known; and the mechanisms for EIH are unclear at any age. This dissertation aimed to address these unknowns through a series of three studies. In study one, repeatability of pressure pain reports (pain threshold and pain ratings) was assessed in healthy older adults, including the impact of psychological factors. Pain reports, measured before and after quiet rest, did not change following quiet rest. Higher state …

BACKGROUND

• Older adults are at increased risk for falls and fall related injuries, leading to loss of independence, disability, and increased mortality.
• Preventing injury and falls is a national Healthy People 2010 objective. However, physicians and other health professionals frequently fail to incorporate known evidence into usual care. Screening for falls is not consistently performed as an essential assessment in older adults by primary care providers.
• Multidisciplinary assessment can be an important component in preventing falls in community dwelling adults.
• In new practice models, such as the Chronic Care Model, there is an emphasis on interdisciplinary collaboration, however health professions …

Corticospinal Integration In Healthy Humans, Amanda Asmar, Leandra Manfredini, Kerri Mclean, Christina Scannapieco

Dissertations, Theses, and Capstone Projects

Synchronized arrival of neuronal signals from the periphery and motor cortex has been associated with neuronal plasticity and motor learning. The main objective of this study was to examine neuronal interactions following excitation of descending motor axons from the primary motor cortex (M1) and spinal neuronal circuits via transcranial magnetic stimulation (TMS) and transcutaneous electric stimulation of the spine (tsESS) in 15 healthy humans while seated semiprone. TMS was delivered below or above the resting motor evoked potential (MEP) threshold, for the tibialis anterior (TA) muscle, while tsESS was delivered at the lowest stimulation intensity that evoked responses in most …

Cortical Modulation Of Spinal Reflexes In Healthy Humans, Caitlin Bedell, Joseph Capogrosso, Kristin Thomas, Charlotte Westmoreland

Dissertations, Theses, and Capstone Projects

Considerable evidence suggests that monosynaptic and polysynaptic spinal reflexes are prone to corticospinal inputs. The goal of this study was to establish the cortical modulation of monosynaptic and polysynaptic spinal reflexes in healthy humans. Cutaneomuscular responses were evoked following stimulation of the medial edge of the right foot with a 30 ms pulse train every 10 s via a bipolar electrode and recorded from the ipsilateral tibialis anterior (TA) muscle. Across subjects, medial edge foot stimulation was delivered at 1.2 to 1.5 times the response threshold. The soleus H-reflex was evoked and recorded via conventional methods. The effects of transcranial …

The Effect Of Tdcs On Cd-1 Mouse Behavior Post Induced Sensorimotor Cortex Injury, Michelle Gardella, Natalia Gozias, Kristina Laktionova, Tricia Roehrig

Dissertations, Theses, and Capstone Projects

The functional topography of the motor cortex has been shown to be modifiable by transcranial direct current stimulation (tDCS). tDCS works by directing electrical currents into the brain which induces alterations in neuroplastic cortical excitability. This experiment’s aim was to test the effect of tDCS on recovery of skilled locomotion, recovery of balance, and recovery of grip strength after bilateral electrolytic lesions to sensorimotor cortices in mice. Tests employed in this experiment included the ladder test, grip test, and a balance pole test. We were able to show that 4 days of tDCS post brain injury in mice produced improvements …

Comparison Of An Intermittent Vs. Continuous Walking Program In Persons With Multiple Sclerosis Using The 6 Minute Walk Test: A Randomized Crossover Pilot Study, Stefanie Dicarrado, Bridget Dungan, Elizabeth Huallpa, Jacob Potrzeba

Dissertations, Theses, and Capstone Projects

Background: Difficulty with gait is one of the most common complaints of persons with MS (pwMS) and can be due to many causes, including neurogenic fatigue. Neurogenic fatigue is one of the most common MS symptoms, and can prevent pwMS from walking longer distances, thus limiting their ability to improve gait endurance. Intermittent walking, a technique where persons take breaks during walking rather than walking continuously, may allow for pwMS to walk longer distances due to less accrual of fatigue.

Objectives: The purpose of this pilot study was to examine whether a program of intermittent walking will result in a …

Motor Imagery And Action Observation As An Alternative Gait Training Intervention For The Elderly, Matthew F. Cirelli, Brian Fettner, Lindita Ismaili, Danielle Jordan

Dissertations, Theses, and Capstone Projects

Motor imagery (MI) is the mental representation of movement without any body movement. Action observation (AO) is a non-physical method of training, in which the learner observes the action of another individual. Eighteen subjects between ages 60-80 were randomly assigned to 3 training groups, the MI, AO and motor training groups. All subjects were assessed and measured with the Expanded Timed-Get Up and Go (TUG) test and Figure-8-Walk (F8W) test. All three groups yielded a significant improvement in difference in total TUG time (<0.05). When individual aspects of the TUG were considered, the sit to stand component improved in the MI and Motor groups. The results of this study suggest that MI and AO can improve cadence and have an effect mirroring that of motor practice. If utilized properly, MI and AO may be indicated as a rehabilitation intervention adjunct to gait training, and potentially decrease the risk of falls in the elderly population.
