Specificity of a Back Muscle Exercise Machine in Healthy and Low Back Pain Subjects

Abstract

These results showed that this type of exercise machine can specifically train the back muscles, and this as much in subjects with nonspecific chronic low back pain as in healthy controls. This has implications for the training of back muscle endurance, especially in patients with back pain for whom poor back muscle endurance is sometimes of concern.

Energetics and mechanics of walking in patients with chronic low back pain and healthy matched controls

“…In the present study, whereas pain VAS remained around 30 at all walking speeds, the task was perceived as more difficult by patients with cLBP than controls, as indicated by a higher level of perceived exertion, but this difference was not intensified with increasing speed. In a previous study, a back fatiguing task was subjectively perceived as more strenuous by patients with cLBP than healthy controls, whereas objective EMG recordings showed no significant difference between groups (Lariviere et al 2010). Ratings of perceived exertion may be influenced by factors such as pain and fear of movement (Barker et al 2003;Wallbom et al 2002).…”

Correlation between architectural variables and torque in the erector spinae muscle during maximal isometric contraction

“…It is common for researchers to measure changes in functional parameters that depend on strength (force, torque, etc.) (Al-Mulla, Sepulveda, & Colley, 2011;Delp, Suryanarayanan, Murray, Uhlir, & Triolo, 2001;Larivière et al, 2010) in order to understand the factors contributing to joint movements, from anatomical (lever arm or muscle size for example) and/or neuromotor (synergist, antagonist and agonist activation) perspectives (Blazevich, Coleman, Horne, & Cannavan, 2009).…”

Effects of hand and knee positions on muscular activity during trunk extension exercise with the Roman chair

“…As these muscle groups are activated together to generate extensor moments for trunk extension, several previous studies have investigated methods of selectively activating each muscle group, particularly for the thoracic and lumbar musculature (Smith et al, 2011;Larivière et al, 2010;Da Silva et al, 2009;Mayer et al, 2008). Da Silva et al (2009) reported that back exercise in a semi-sitting position could be a useful method of localizing the effects of endurance training on the muscles of the lumbar and thoracic region.…”
