Measurement of Sternal Separation with Functional Activities After Sternotomy in Regards to Sternal Precautions: A Pilot Study.

The purpose of the study is to examine common daily activities and the influence they have on the healing process of the sternum after open sternotomy. Sternal separation after open sternotomy is measured with ultrasound during various activities such as upper extremity movement and functional activities (i.e. sit to stand). The outcomes of this study may influence sternal precautions that are routinely given to patients after an open sternotomy and help to direct healing of the sternum post-operatively.

Measurement of Lower Extremity Strength in Individuals with Upper Motor Neuron Injury

Patients with Upper Motor Neuron (UMN) injuries such as stroke often experience multiple impairments such as weakness, spasticity, hypertonicity, and synergistic movement. Standard methods of examining strength in orthopedic patients such as Manual Muscle Testing (MMT) and Hand Held Dynamometry (HHD) were thought to be invalid for patients after stroke, due to the interactions of all impairments beyond weakness itself.  Previous study of hip extension strength measurementhas led us to believe that HHD may be a valid measure of strength in patients with UMN deficits of any severity, and MMT may be a valid measure of strength in patients with minimal severity. 

Therefore, the purpose of this study is to determine the validity of the MMT and HHD for strength testing in patients with UMN dysfunction.
