Motion Analysis And Electromyographic Analysis Of Ambulation With Assistive Devices, Tracy Foltz, Danielle Jwanouskos, Steven Pederson

Physical Therapy Scholarly Projects

Purpose: The purpose of this study is to analyze the amount of muscle activity of the rectus abdominis and external obliques during the gait cycle with the use of forearm crutches and three different weight bearing statuses. Subjects: Seven female adults were recruited from the University of North Dakota Physical Therapy program. Inclusion criteria: between the ages of 19 and 40 years of age, current physical therapy students, and healthy with no current upper or lower extremity injuries.

Instrumentation: The EMG data was collected by the Noraxon Telemyo 900 telemetry unit and analyzed using the MyoResearch XP software. Six Vicon …

Backward walking is a common intervention in the rehabilitation of lower extremity injuries. Despite its popularity, there is limited research available on the EMG activity during backward walking at an incline when compared to forward walking. In this study, we recorded EMG activity in four muscles of the lower extremity and utilized motion analysis to evaluate the knee range of motion when walking forward and backward on a treadmill at 0 and 15 percent grade inclines.

Overall, our results indicated a greater increase in muscle activity during backward walking than forward walking. Walking backward at a 15 percent grade incline …

An Electromyographic Analysis Study Of Forward And Backward Walking, Jennifer C. Coauette

Physical Therapy Scholarly Projects

Backward walking, a closed kinetic chain exercise, has become an increasingly popular intervention following lower extremity injuries secondary to suggested increases in muscle activity. Despite its use, there is limited research available relative to walking at inclines, forwards or backwards above 24 and 15 percent respectively. For this study we recorded EMG activity in six muscles while walking forward and backward on a treadmill at 0, 25, and 35 percent inclinations.

In general, our results indicated a greater increase in muscle activity during BW than FW. BW at 35 percent inclination elicited the greatest EMG increase within the rectus femoris …

An Electromyographic Study Of Backward Walking In Normals And In Subjects Following Anterior Cruciate Ligament Repair, Matthew Johnson

Physical Therapy Scholarly Projects

Physical therapy strives to incorporate innovative and efficient protocols for rehabilitation of anterior cruciate ligament (ACL) surgeries. Research supports the benefits of closed kinetic chain exercises (distal segment of extremity is fixed) over the traditional open kinetic chain exercises (distal segment not fixed). It is theorized that backward walking on inclined surfaces will recruit the knee musculature to a greater extent than forward walking, but there is little research to support this theory. The purpose of this study was to utilize electromyography during treadmill walking to analyze the muscle activity in the lower extremity of individuals were normal and who …

The Effect Of Backward Treadmill Walking On Lower Extremity Kinetics, Scott Billing

Physical Therapy Scholarly Projects

Many physical therapy diagnoses require minimal anterior loading of the knee in their rehabilitation protocols. These include, but are not limited to, tibial plateau fractures, patellofemoral pain, patellar fractures, quadriceps tendinitis, and status post anterior cruciate ligament reconstruction. In the clinical setting, backward walking (BW), or "retro-walking," is often used during the rehabilitation of such diagnoses. We propose backward walking will initiate greater hamstring recruitment due to the kinematics and kinetics of this gait pattern and thereby result in less anterior knee stress. It is the purpose of this research project to determine if hamstring recruitment can increase in a …
