Die isokinetische Kraftleistungsfähigkeit der Rumpfmuskulatur von Patienten mit chronischen Rückenschmerzen

Abstract

Lumbar isokinetic strength and the influence of age, bodyweight and testing velocity in patients with chronic low back pain in comparison with persons without pain. Lumbar isokinetic strength parameters of 80 patients with chronic low back pain and 70 persons without pain were compared and the influence of age, bodyweight and testing velocity was evaluated. The patients with chronic low back pain showed less strength than the persons without pain. All parameters of extension discriminated between the two groups whereas only some of the flexion parameters did. The isokinetic strength of the lumbal extension muscles was higher than the strength of the flexion muscles. In patients with chronic low back pain, isokinetic strength of lumbar extension muscles was more reduced than the strength of flexion muscles in comparison with persons without pain. At 90 degrees/sec in comparison to 60 degrees/sec, lower extension forces, higher flexion forces and changed ratios of flexion and extension muscles were measured. Age had an influence only on women. There were no changes in ratios of flexion and extension muscles with increasing age. Bodyweight showed weak correlations with isokinetic flexion forces. The influence of different factors on isokinetic force varies between patients with chronic low back patients and healthy subjects.

The Effect of Autogenous Fascia Relaxation and Spinal Mobility Exercise on Pain and Range of Motion in Elderly Female Patients with Chronic Back Pain

“…The intensity of the pain depends on the degree of contraction of the fascia that maintains the normal shape of the body, muscles, nerves and skeleton (10). Relying solely on drug formulations and injections as a therapeutic approach to improving back pain can limit flexibility and reduce core strength and spinal durability, resulting in recurrence of pain (11). Fascia Relaxation Exercise, a nerve and fascia system recommended by the National Academy of Sports Medicine (NASM), SMR uses foam rollers and braces to inhibit irritable muscle fibers and to reduce the emotional or physical effects of the autonomic nervous system, such as vasodilation and increased muscle contraction.…”

Deformations of abdominal muscles under experimentally induced low back pain

“…Low back pain (LBP) is associated with altered motor control and muscle activity. A number of studies have shown a link between LBP and delayed muscle onsets [1], lower level of motor variability [2], reduced muscle activation of the trunk, increased stiffness [3], lower muscle force [4], changes in muscles' voluntary activity [5] and higherordered movement capacities, such as gait [6,7]. Interestingly, although all of these behavioural features have their own underlying physiological changes (e.g.…”
