Thesis Ph. D. Michigan State University. Physiology 2019.

Thumb carpometacarpal (CMC) motion, motion between the thumb and the wrist, is primarily responsible for our ability to grasp objects, open jars, and makes up 50% of arm function1,2. To improve hand function and the quality of life in persons with CMC osteoarthritis (OA), it is critical that we improve our ability to monitor changes in thumb function. The first step is to augment our methods to quantify the functional losses and used these methods to identify effects of treatment.The overarching goal of this work was to quantify the differences in motion and force abilities of persons with and without thumb CMC OA, and to measure the ability of hand stretching and strengthening exercises to increase thumb function in persons with CMC OA. Initial motion and force datasets were collected from young healthy persons (n = 23), older healthy persons (n = 11), and older persons with diagnosed CMC OA (n = 24). Following collection of initial datasets, study participants were given daily hand stretching exercises. After two weeks, motion and force datasets were collected a second time. Participants then were given daily strengthening hand exercises to be completed in addition to the daily stretching exercises. Following four weeks of combined stretching and strengthening exercises, participant motion and force datasets were collected a final time.For this work, there were three aims:Aim 1 was 1) to develop a method to measure isolated thumb forces in multiple directions, 2) to demonstrate this method on three populations, young healthy, older healthy, and older participants with OA of the CMC joint, and 3) to identify the effects of short-term hand exercises on thumb force production and grip strength in these three groups. Results showed that both thumb and grip forces improved in young healthy females, older healthy females and males, and older osteoarthritic females and males. In contrast, young healthy males increased their grip forces following exercise, but not their thumb strength. This suggests that thumb and strength forces are not interchangeable, and that thumb forces should be collected in a clinical setting to better track the effects of intervention (exercise, surgery, etc.) on thumb function.Aim 2 was 1) to determine differences in thumb motions across three groups of participants (i.e., young healthy, older healthy and those with CMC OA) and 2) to determine if multi-planar motions provided additional movement information in comparison to standard planar measures. Both standard thumb ranges of motion typically collected in clinic and new multi-planar motion datasets were obtained from all participants. Results indicated that motion capture was capable of detecting changes in CMC mobility due to the effects of aging and OA pathophysiology that were not detected using standard approaches, and use of multi-planar measurements have the potential to identify changes that are indicators of early stages of OA.Aim 3 was to identify changes in CMC motions as a…

2. Gustafsson, Ewa. Physical exposure, musculoskeletal symptoms and attitudes related to ICT use.

Degree: 2009, University of Gothenburg / Göteborgs Universitet

High prevalence of musculoskeletal symptoms/disorders in neck and upper extremities are reported among computer users. Considering the widespread use of information and communication technology (ICT) and mobile phones becoming more and more like computers with small keyboards it is of importance to identify the factors and conditions related to this use, that influence our health. The overall aim of this thesis was to obtain new ergonomic knowledge of the physical exposure associated with the use of information and communication technology with emphasis on small keyboards, computer mice and young adult ICT users. In an interview study with young adult ICT users, where the data analysis was performed with the grounded theory method, was showed that the young adults experienced ICT as a tool for being and acting in the present, to be social, efficient and independent with almost unlimited opportunities but also risks. A comparative experimental study with experienced computer mouse users evaluated muscle activity with surface electromyography and wrist positions/movements with electrogoniometry during work with a traditional flat computer mouse (pronated hand position) and a vertical computer mouse (neutral hand position). Work with the vertical computer mouse decreased the muscle activity in the extensor muscles in the forearm and in the first dorsal interossei muscle, and the ulnar deviation in the wrist compared to the traditional mouse. An experimental study, with young adults with and without musculoskeletal symptoms from neck and/or upper extremities, evaluated thumb positions/movements with electrogoniometry, muscle activity with surface electromyography, and working techniques with an observational protocol when text entering on a mobile phone. The young adults with symptoms had lower muscle activity in the abductor pollicis longus and tended to have higher velocity and fewer pauses in the thumb movements compared to those without symptoms. Females had higher muscle activity in the first dorsal interossei and the abductor pollicis longus compared to males. It was more common in the group with symptoms to sit with the head bent forward, to sit without forearm and back support and to enter text with one thumb rather than two compared to those without symptoms. Use of forearm support decreased the muscle activity in the trapezius muscles. Use of one hand grip increased the muscle activity in the extensor muscles in the forearm. High observed velocity in the thumb movements was associated with increased muscle activity in the extensor muscles in the forearm compared to low or moderate velocity. In conclusion, this thesis shows that computer mouse design has an effect on the muscle activity in the forearm and hand, and on the wrist positions and movements. It also shows that the individual factors working technique and gender have an effect on muscle activity and thumb movements when entering text on a mobile phone. Furthermore, there were differences in working techniques, thumb movements, and muscle activity…

3. Galeano, Elisa Braga. Rachmaninoff's Trio Elegiaque, Op 9: A Performer's Guide.

Degree: DMA, Music, 2016, Louisiana State University

URL: etd-08242016-090339 ; https://digitalcommons.lsu.edu/gradschool_dissertations/4125 

This document and the accompanying lecture/recital performance aim to call more attention to this intense and deeply emotional work. Focus will be placed on the technical challenges in the piano part while making recommendations for the performer when appropriate. As background, an overview of Rachmaninoff’s early life and work is presented in order to provide a clearer understanding of what led him to compose this trio. Of particular importance in the writing of this piece was the direct influence of Peter Tchaikovsky’s Trio, Op 50, which will also figure prominently in the background discussion.

Subjects/Keywords: considerations for the pianist; circular hand and arm movements; D minor trio; chamber music; technical challenges for pianist; concerto passages; a la memoire d’un grand artiste; heavy chordal sonorities; elevated wrist and arm; high thumb positions; keyboard cadenzas
