In Vivo Erector Spinae Muscle Blood Volume and Oxygenation Measures During Repetitive Incremental Lifting and Lowering in Chronic Low Back Pain Participants

Abstract

The results indicated that the chronic LBP participants demonstrated a reduced cardiorespiratory and erector spinae muscle response during repetitive incremental lifting and lowering to volitional fatigue as compared to the healthy controls.

Effect of opioid administration on cardiorespiratory and muscle oxygenation during lifting in chronic back pain patients

“…In the current study we did not measure the VO 2max of the participants. However, previous research (Kell and Bhambhani 2006) from this laboratory has indicated that the VO 2peak during a repetitive incremental lifting and lowering protocol to voluntary fatigue averaged 2.54 § 0.58 L/min in healthy male and female subjects and 2.29 § 0.52 L/min in male and female LBP subjects.…”

“…The repetitive lifting and lowering (RLL) protocol was then administered using a modiWed procedure that has been used previously in subjects with LBP (Kell et al 2004;Kell and Bhambhani 2006). The participant was asked to repetitively complete dynamic Xoor-to-waist lifting from the table to the Xoor, then back to the table.…”

“…The sum of the tissue absorbencies at the two wavelengths provides an index of the local blood volume which is considered to be an index of muscle blood Xow (Hamaoka et al 2007). NIRS procedures for measuring muscle oxygenation during the repetitive lifting procedure in healthy and LBP subjects have been previously described (Kell and Bhambhani 2006) and its test-retest reliability has been demonstrated (Kell et al 2004). Two NIRS probes were placed bilaterally at the level of the third lumbar vertebra, approximately 3 cm from the midline.…”

Low Back Pain in Patients with Lumbar Spinal Stenosis-Hemodynamic and electrophysiological study of the lumbar multifidus muscles

“…Papers focused on hemodynamic aspects of the lumbar muscle related to LBP are sporadic. Recently, more studies are investigating the cause of LBP in terms of oxygen consumption and hemodynamics besides our previous study 13,27,28) . Several clinical studies have tried to identifying whether oxygen consumption and dynamics change play an important role in the pathology of LBP at the level of paraspinal muscles.…”

“…Regarding the differences in oxygen consumption at the lumbar muscle between healthy and LBP individuals, Kovac et al suggested using NIRS that the patients with muscular LBP did not use the available oxygen during exercise and that there is an inability to consume oxygen due to mitochondrial damage caused by their muscle damage 27) . Kell et al investigated hemodynamics in healthy and chronic LBP subjects using NIRS, and identified differences in paraspinal muscle blood flow and oxygenation responses during dynamic incremental work 28) . However, whether the muscle blood flow impairment represents the cause of LBP or it is a secondary change due to LBP remains controversial.…”
