STUDY DESIGN A test-retest design was used. OBJECTIVE To assess interexaminer reliability of the McKenzie method for performing clinical tests and classifying patients with low back pain. SUMMARY OF BACKGROUND DATA Clinical methods and tests classifying patients with nonspecific low back pain have been based mainly on symptom duration or extent of pain(More)
CONTEXT Active physical training is commonly recommended for patients with chronic neck pain; however, its efficacy has not been demonstrated in randomized studies. OBJECTIVE To evaluate the efficacy of intensive isometric neck strength training and lighter endurance training of neck muscles on pain and disability in women with chronic, nonspecific neck(More)
OBJECTIVE To compare the lumbar paraspinal and gluteus maximus muscle fatigability between chronic low back pain patients and healthy controls by using electromyographic (EMG) spectral analysis during a maximal isometric endurance task. DESIGN A cross-sectional comparative study between chronic low back pain patients and healthy control subjects. (More)
BACKGROUND Movement control dysfunction [MCD] reduces active control of movements. Patients with MCD might form an important subgroup among patients with non specific low back pain. The diagnosis is based on the observation of active movements. Although widely used clinically, only a few studies have been performed to determine the test reliability. The aim(More)
Impairment and disability after back surgery is a common diagnostic and therapeutic problem. For the most part the reasons are unclear. Of 178 patients who had undergone laminectomies 2-5 years earlier, 14 patients with good recovery and 21 patients with poor recovery but no evidence of restenosis on computed tomography were selected by the Oswestry index.(More)
STUDY DESIGN A randomized study comparing the results of active rehabilitation and passive control treatment in patients with chronic low back pain with follow-up at 6 months and 1 year. OBJECTIVES To study the efficacy of active rehabilitation on pain, self-experienced disability, and lumbar fatigability. SUMMARY OF BACKGROUND DATA Exercises in an(More)
OBJECTIVES To assess the paraspinal and abdominal muscle activities during different therapeutic exercises and to study how load increment produced by varying limb movements and trunk positions could affect these muscle activities. DESIGN A cross-sectional study comparing muscle activities between men and women. SETTING Rehabilitation clinic in(More)
STUDY DESIGN A comparative study of lumbar paraspinal muscle reflexes during sudden upper limb loading in healthy control subjects and patients with sciatica. OBJECTIVES To assess reflex activation of paraspinal muscles during sudden upper limb loading. SUMMARY OF BACKGROUND DATA Sudden upper limb loading and upper limb voluntary movements cause reflex(More)
BACKGROUND Therapeutic exercises are widely used in the treatment of low back problems. Clinical knowledge about targeting the load in these exercises, however, is insufficient. This study assessed the L2 and L5 level paraspinal and gluteus maximus muscle activities in different therapeutic exercises. Intramuscular and surface electromyography (EMG)(More)
