The Impact Of Left Hemisphere Stroke On Force Control With Familiar And Novel Objects: Neuroanatomic Substrates And Relationship To Apraxia, Amanda M. Dawson, Laura J. Buxbaum, Susan V. Duff

Physical Therapy Faculty Articles and Research

Fingertip force scaling for lifting objects frequently occurs in anticipation of finger contact. An ongoing question concerns the types of memories that are used to inform predictive control. Object-specific information such as weight may be stored and retrieved when previously encountered objects are lifted again. Alternatively, visual size and shape cues may provide estimates of object density each time objects are encountered. We reasoned that differences in performance with familiar versus novel objects would provide support for the former possibility. Anticipatory force production with both familiar and novel objects was assessed in six left hemisphere stroke patients, two of whom …

Performance Of A Hip Protector Depends On Its Position During A Fall, Woochol J. Choi, Joaquin A. Hoffer, Stephen N. Robinovitch

Physical Therapy Faculty Articles and Research

"Hip protectors are designed to attenuate and redistribute the force applied to the hip region during a fall, and thereby reduce risk for hip fracture [1]. However, little information exists on the effectiveness of hip protectors in achieving these goals, and how this is altered by displacement of the hip protector relative to the greater trochanter (GT). In the current study, we tested these issues."

Peer-Led Team Learning: A Prospective Method For Increasing Critical Thinking In Undergraduate Science Courses, Ian J. Quitadamo, C. Jayne Brahler, Gregory J. Crouch

Physical Therapy Faculty Publications

This study examined the impact of peer-led team learning (PLTL) on critical thinking gains in science and math courses at a research university in the Pacific Northwest.

Gastrocnemius-Soleus Muscle Tendon Unit Changes Over The First 12 Weeks Of Adjusted Age In Infants Born Preterm, Marybeth Grant-Beuttler, Robert J. Palisano, Debra P. Miller, Barbara Reddien Wagner, Carolyn B. Heriza, Patricia A. Shewokis

Physical Therapy Faculty Articles and Research

Background and Purpose: Differences in the gastrocnemius-soleus muscle and tendon have been documented shortly after birth in infants born preterm compared with infants born at term. Knowledge of muscle tendon unit lengths at term age to 12 weeks of age in infants born preterm may be useful in understanding motor development.

Participants and Method: Gastrocnemius-soleus muscle tendon unit lengths were compared at term age, at 6 weeks of age, and at 12 weeks of age (preterm adjusted age) in 20 infants born full term and 22 infants born preterm.

Results: Significant differences were found between the 2 groups on taut …

Author Response To Invited Commentary By Heathcock [Commentary For: Gastrocnemius/Soleus Muscle Tendon Unit Changes Over The First 12 Weeks Of Adjusted Age In Infants Born Preterm], Marybeth Grant-Beuttler, Robert J. Palisano, Debra P. Miller, Barbara Reddien Wagner, Carolyn B. Heriza, Patricia A. Shewokis

Physical Therapy Faculty Articles and Research

"We thank Heathcock for taking the time to write her commentaryregarding our study. Her comments are interesting, and our subsequent investigation into these ideas has led us to uncover some enlightening evidence in relation to the topics raised in the commentary. We will attempt to review each of the topics raised and the evidence associated with these topics."

Chronic Elbow Dislocation Treated With Open Reduction And Lateral Ulnar Collateral Ligament Reconstruction, Louis Joseph Rubino, Michael A. Herbenick, Ryan P. Finnan, Philip A. Anloague

Physical Therapy Faculty Publications

In the United States, chronic unreduced elbow dislocations are rare injuries. We report the successful short-term outcome of a chronic elbow dislocation treated with open reduction and lateral ulnar collateral ligament reconstruction using a split semitendinosus allograft in a figure-of-8 technique without use of hinged external fixation. The authors have obtained the patient’s written informed consent for print and electronic publication of the case report.

Interrupted Resistance Training And Bmd In Growing Rats, J. K. Godfrey, B. D. Kayser, G. V. Gomez, Jason Bennett, S. V. Jaque, Ken D. Sumida

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

A resistance training program, where the exercise was uninterrupted (UT, i.e. continuous repetitions) was compared against another resistance training program where the exercise was interrupted (IT, i.e. 2 exercise sessions during a training day) for enhancing bone modeling and bone mineral density (BMD) in maturating animals. The total volume of work performed between the two resistance training programs was equivalent by design. Young male rats (similar to 8 weeks old) were randomly divided into Control (Con, n = 8), UT (n = 8) and IT (n = 7) resistance trained groups. The UT and IT groups were conditioned to climb …

Control Of Myosin Motor Activity And Actin Filament Translation By Alteration Of Assay Reducing Potential, Siva Krishna Nalabotu

Theses, Dissertations and Capstones

The use of biomolecular motors for nanotechnological applications has been impaired by an inability to control biomolecular motor activity in a temporal fashion. Previous data has suggested that myosin activity can be modulated by inducing changes in the degree of myosin oxidation. The hypothesis of this study is that myosin motor activity can be regulated by altering the amount of antioxidants and reducing agents present in assay solution. To test this hypothesis we systematically altered the concentration of reducing agents and examined the effects of these changes on myosin-dependent actin filament translation. Our findings indicate that myosin activity can be …

Use Of Topical Nsaids In Acute Musculoskeletal Sports Injury: A Brief Review, Amit M. Deokar, Shawn J. Smith, Hatim A. Omar

Pediatrics Faculty Publications

The objective of this chapter is to summarize the current standards of pain management in minor sports-related musculoskeletal injuries. This chapter also addresses the topical form of non-steroidal anti-inflammatory drug as an effective pain management option in an outpatient setting. Design: Quantitive systematic review of randomized controlled trials. Methods: The data was obtained through literature review of articles published in the last 10 years. In addition, FDA information on non-steroidal anti-inflammatory medications was also reviewed. The patient population studied in the articles included children and adults. Conclusion: Current standards of managing pain resulting from sports injuries involve a number of …
