Functional Rehabilitation: Managing Low Back Pain Through Activities-Of-Daily-Living Education, Timothy E. Speicher, R. Daniel Martin, Robert M. Desimone

All PTHMS Faculty Publications

After trauma to the low back, a decrease in intervertebral joint stiffness can occur, which can lead to inability of the motor-control system to compensate for the tasks imposed on the tissues, resulting in spinal instability. Intervertebral joint stiffness can be thought of as a tightening of a corset around a spine segment, facilitated through coactivation of small and large spinal muscles. The motor-control system might be able to adapt initially with cocontractions of the intrinsic muscles, but an unbalanced demand between the small and large muscles can lead to muscle fatigue and poor task performance. The inability of the …

Comparison Of Frontal Plane Trunk Kinematics And Hip And Knee Moments During Anticipated And Unanticipated Walking And Side Step Cutting Tasks, Jeff R. Houck, Andrew Duncan, Kenneth E. De Haven

Faculty Publications - College of Physical Therapy

Background: Frontal plane trunk and lower extremity adjustments during unanticipated tasks are hypothesized to influence hip and knee neuromuscular control, and therefore, contribute to anterior cruciate ligament (ACL) injury risk. The aims of this study were to examine frontal plane trunk/hip kinematics and hip and knee moments (measures of neuromuscular control) during unanticipated straight and side step cut tasks.

Methods: Kinematic and kinetic variables were collected while subjects performed two anticipated tasks, including walking straight (ST) and side step cutting (SS), and two unanticipated tasks (STU and SSU). Foot placement, thorax–pelvis–hip kinematic variables and hip and knee moments were calculated …

Does Motor Lateralization Have Implications For Stroke Rehabilitation?, Robert L. Sainburg, Susan V. Duff

Physical Therapy Faculty Articles and Research

Recent findings on motor lateralization have revealed consistent differences in the control strategies of the dominant and nondominant hemisphere/limb systems that could have implications for hemiplegic stroke patients. Studies in stroke patients have demonstrated deficiencies in the ipsilesional arm that reflect these distinctions; patients with right-hemisphere damage tend to show deficits in positional accuracy, and patients with left-hemisphere damage show deficits in trajectory control. Such deficits have been shown to impede functional performance; yet patients with severe dominant-side hemiplegia must often use the nondominant arm as the primary manipulator for activities of daily living. Nevertheless, the nondominant arm may not …

Variations In Emg Activity In Lower Leg Musculature With Use Of The Biomechanical Ankle Platform System (Baps), Carrie Carpenter, Andrea Lund, Jodi Sailer, Slinde Jessie

Physical Therapy Scholarly Projects

Ankle sprains account for 17% to 20% of all injuries in most sports. Other ankle conditions such as posterior tibialis tendon disorder and Achilles tendinosis are quite common in the nonathletic population and require many of the same interventions. Some of these interventions include range of motion, stretching, strengthening and proprioception. Many studies have shown that strength and proprioceptive training are the intervention of choice for those with lateral ankle instability. Many of these studies have supported the use of BAPS in improving proprioception among individuals with lateral ankle instability, however there is only one study examining the use of …

Top-10 Positional-Release Therapy Techniques To Break The Chain Of Pain: Part 2, Timothy E. Speicher, David O. Draper

All PTHMS Faculty Publications

Positional-Release Therapy (PRT) is advocated as an effective indirect therapeutic treatment for acute, subacute, and chronic somatic dysfunction. Initial investigations have shown PRT to significantly reduce low back and hip pain and improve hip strength. The effects of PRT are thought to occur from placing a patient’s tissues in a position of comfort for an extended period of time.

Clinically, the practice of PRT and its therapeutic benefits have an established history. What is lacking is research into the neural and physiologic mechanisms of the process by which PRT alleviates somatic dysfunction. It can be tempting to view the technique …
