1. Lumbar muscle fatigue : analysis of electromyography, endurance time and subjective factors in patients with lumbar disc herniation and healthy subjects
Abstract : The overall aim of the thesis was to investigate the relation between objectively and subjectively assessed lumbar muscle fatigue and subjective factors in patients with lumbar disc herniation and in healthy subjects. Eighty healthy subjects and 43 patients undergoing surgery for lumbar disc herniation and selected consecutively for the study participated. READ MORE

2. Biomechanics of back extension torque production about the lumbar spine
Abstract : The aim of this thesis has been to develop a realistic mechanical description of lumbar back extension torque production. Such a description is desirable for understanding how back extension torque is generated as well as how the spine and surrounding structures are loaded during back extension tasks. READ MORE

3. Lumbar muscle fatigue and recovery : evaluation of electromyography in patients with long-term low-back pain and in healthy subjects
Abstract : Background: Lumbar muscle function is considered to be an important component of longterm low- back pain. The change in the median frequency of the power spectrum of the electromyographic (EMG) signal is commonly used to estimate muscle fatigue. READ MORE

4. Idiopathic scoliosis : radiographic, neurophysiologic and psychologic aspects
Abstract : The aim of this thesis was to study brace treatment outcome, the brace effect on electromyographic muscle responses and self image, possible occurrence of somatosensory dysfunction and the descriptive power of surface topography contra radiography, in idiopathic scoliosis. There were 64 patients in a retrospective 4. READ MORE
