The Effect Of Familiar And Novel Testing Environments On The Gross Motor Function Measure Scores Of Developmentally Normal Children 17-37 Months Old, Tracey Blain, Jean Angel

Masters Theses

Our purpose in this research was to compare the reliability of the Gross Motor Function Measure in familiar and unfamiliar environments. Discrepancy between clinical assessment results and true motor functional ability may give false information leading to inefficient treatment sessions. Our research gives therapists information about optimal assessment site choice. Subjects included sixteen developmentally normal children between the ages of 17 and 37 months. Our study fit a repeated measure counterbalanced design, and ANOVA was used to analyze our data. We did not reject our null hypothesis that the child’s score on the GMFM in the familiar environment would equal …

Knee Flexion Angle And Its Influence On Vmo:Vl Ratios During Isometric Quadriceps Contraction, Jeffrey P. Hendra, William D. Allan

Masters Theses

Patellofemoral Pain Syndrome (PFPS) is a major cause of knee pain and is caused by lateral patellar tracking. Treatment consists of strengthening the vastus medialis obliquus (VMO). While many exercises strengthen the VMO, simultaneous vastus lateralis (VL) strengthening often occurs and patellar malalignment remains. The VMO must, therefore, be strengthened independently or to a greater extent than the VL. Thus, the VMO:VL ratio of activity must be considered rather than VMO activity alone. This study compared isometric knee extension electromyographically at 0, 20, 60, and 90 degree angles to determine which angle produced the greatest VMO:VL ratio of activity. Results …

A Comparative Electromyographic Study Of The Effect Of Four Selected Closed Chain Squat Exercises On Vastus Medialis Oblique And Vastus Lateralis, Barbara D. Campbell, Michelle Kosiara, Heidi Tolloff

Masters Theses

Patellofemoral dysfunction (PFD) usually involves patellar maltracking. Vastus medialis oblique (VMO) and vastus lateralis (VL) are two key muscles that help maintain patellar alignment. Open kinetic chain (OKC) studies suggested that the optimum ratio of VMO:VL is about 1:1. With PFD the VMO becomes much weaker. Purpose: To determine which of four partial squat exercises, often used in rehabilitation, best favors VMO firing: partial squat, partial squat squeezing a ball between knees, partial squat with pulley resistance and partial squat with 45° oblique pulley resistance. Analysis of EMG for 31 normal subjects randomly performing all four exercises using repeated ANOVA …

A Preliminary Study Of Gait In Elderly Women With Diabetic Peripheral Neuropathy, Roberta M. Fischer, Sheri L. Bjornseth

Masters Theses

Somatosensory impairment due to diabetic peripheral neuropathy results in decreased environmental input during ambulation, which may compromise feedback mechanisms used for balance control Individuals with distal symmetrical diabetic peripheral neuropathy provide a model of somatosensory loss in which balance impairments can be studied. Somatosensory input is an important component of standing balance in the elderly. Diabetic peripheral neuropathy has been associated with postural instability and an increased history of falls. This study investigated differences in gait between elderly diabetic subjects with distal symmetrical sensory polyneuropathy and elderly diabetics without neuropathy. To conduct this study the 3-dimensional gait analysis protocol developed …

The Relationship Of Eccentric Hamstrings Time To Peak Torque And Anterior Knee Joint Displacement, Julie Ann Clark, Maureen B. Godfrey, Noreen R. Laborde

Masters Theses

Research suggests that females are more likely to sustain an anterior cruciate ligament (ACL) injury when compared to males and that the ACL and hamstring muscles work together to preserve joint stability. Information is limited regarding any relationship between anterior knee joint laxity, in the absence of injury, and eccentric hamstring time to peak torque. This study compared anterior knee joint displacement and eccentric hamstrings time to peak torque in 30 female athletes and 30 female non-athletes ages 14-18 years. The passive anterior drawer was measured on both lower extremities using the KT-1000® arthrometer before and after eccentric hamstrings time …

Relationship Between Sensibility Loss And Performance On The Jebsen-Taylor Hand Function Test In Non-Surgical Carpal Tunnel Syndrome Patients, Bethany J. Navarre, Elizabeth A. Ware

Masters Theses

The assumed correlation between sensibility loss in carpal tunnel syndrome (CTS) and hand function has not been supported by research. The purpose of this study is to examine this relationship. Thirteen subjects with CTS, no previous hand surgeries, hypothyroidism, or diabetes participated. The Weinstein Enhanced Sensory Test was used to assess sensibility and the Jebsen-Taylor Hand Function Test was used to assess hand function. No correlations were found between sensibility loss and hand function. Despite a small sample, lack of correlation between sensibility loss in CTS and hand function is significant. It suggests that further research is needed.

The Influence Of Footwear On Functional Balance In A Population Of Institutionalized Elderly Women, Kristen Brooks, Stacey Jonkman, Matt Schmitz

Masters Theses

The purpose of this study was to evaluate the influence of footwear on functional balance in a sample of 19 institutionalized elderly women. The Tinetti Balance and Mobility Assessment, a fall risk indicator, was used to evaluate functional balance in three footwear conditions: shoes, slippers, and barefoot. An ANOVA test (alpha < 0.05) was used to determine if there was a significant difference between the three footwear conditions. A significant difference was found between each footwear condition for the balance (p=.008) and summary scores (p=.004), but not for the gait score (p=.155). Post-hoc analysis revealed that the shoe condition provided significantly superior scores than the slipper (p=.005) and barefoot conditions (p=.043). Recommendations from this study include support for the standardization of the Tinetti Balance and Mobility Assessment for footwear, and recommendations that institutionalized elderly should wear shoes and avoid the use of slippers or barefoot to reduce fall risk.
