“…As the kinematic changes measured during FRED exercise in non-symptomatic individuals are likely to be linked to involuntary (but very welcome) tonic LM and TrA activity (Caplan et al, 2014) , this suggests the same muscle activity occurred in those participants in this study with LBP. This may be an indication that FRED exercise is effective as an intervention for tonic recruitment and training of LM and TrA in people with LBP.…”

“…The small amount of estimated increase in lordosis (0.5-1 degree), and it being mostly in the lower lumbar spine, further suggests this postural change was within the range required for LM and TrA to be active. Caplan et al (2014) reported that LM activity on FRED was tonic throughout the exercise, whereas walking resulted in a biphasic recruitment pattern with peaks around heel strike and toe off. As the superficial fibres of LM have a role in lordosis control (Macintosh et al, 1986;Musculino, 2005;Moseley et al, 2002), a tonic LM contraction in FRED exercise compared to walking (Caplan et al, 2014) may also partly explain why increased lordosis and anterior pelvic tilt was found throughout FRED exercise compared to walking.…”

“…It results in LM and TrA activity that is more tonic than walking (Caplan et al, 2014) and increases lumbopelvic stability when compared to over-ground walking (Gibbon et al, 2013). However, the immediate effect of FRED exercise on lumbopelvic kinematics in asymptomatic people or those with LBP has not yet been investigated.…”

BackgroundDysfunction of the lumbar multifidus (LM) and transversus abdominis (TrA) muscles is associated with low back pain (LBP). The Functional Re-adaptive Exercise Device (FRED) has shown potential as a non-specific LBP intervention by automatically recruiting LM and TrA. Loss or lordosis and altered lumbopelvic positioning has also been linked to LBP and is often trained within LM and TrA interventions. The effect that FRED exercise has on lumbopelvic positioning and lumbar lordosis is unknown. ObjectivesTo assess the effect of FRED exercise on lumbopelvic kinematics and alignment to establish whether FRED exercise promotes a favourable lumbopelvic posture for training LM and TrA. DesignWithin and between-group comparison study MethodOne hundred and thirty participants, 74 experiencing LBP, had lumbopelvic kinematic data measured during over-ground walking and FRED exercise.Magnitude-based inferences were used to compare walking with FRED exercise within participants and between the asymptomatic and LBP groups, to establish the effects of FRED exercise on lumbopelvic kinematics, compared to walking, in each group. ResultsFRED exercise promotes an immediate change in anterior pelvic tilt by 8.7 degrees compared to walking in the no-LBP and LBP groups. Sagittal-plane spinal extension increased during FRED exercise at all spinal levels by 0.9 degrees in the no-LBP group, and by 1.2 degrees in the LBP group. ConclusionsFRED exercise promotes a lumbopelvic position more conducive to LM and TrA training than walking in both asymptomatic people and those with LBP. Highlights A posture conducive to LM and TrA training was promoted. The posture appears to occur automatically in people with and without LBP. Exercise on the FRED may be effective for LM and TrA training.

“…It has been shown that the combination of weight bearing in an upright posture and functional leg movement while exercising on the FRED immediately increases the activation of TrA and LM compared to standing on an unstable base or leg movement without weight bearing [10]. Exercise on the FRED also appears to promote an immediate phasic-to-tonic shift in lumbo-pelvic muscle activation as well as an increase in spinal extensor and reduction in spinal flexor muscle activation [7]. These findings suggest that the FRED could provide a useful tool in the rehabilitation of astronauts [12].…”

“…Despite the fact that upright activities such as walking are associated with an activation of deep spinal muscles [7], evidence suggests that the currently applied treadmill exposure is not sufficient to preserve spinal health, given the four-fold increased risk of astronauts experiencing a herniated disc post flight [23].…”

PurposeLumbar multifidus (LM) and transversus abdominis (TrA) show altered motor control, and LM is atrophied, in people with low-back pain (LBP). The Functional Re-adaptive Exercise Device (FRED) involves cyclical lower-limb movement against minimal resistance in an upright posture. It has been shown to recruit LM and TrA automatically, and may have potential as an intervention for non-specific LBP. However, no studies have yet investigated the effects of changes in FRED movement amplitude on the activity of these muscles. This study aimed to assess the effects of different FRED movement amplitudes on LM and TrA muscle thickness and movement variability, to inform an evidence-based exercise prescription.MethodsLumbar multifidus and TrA thickness of eight healthy male volunteers were examined using ultrasound imaging during FRED exercise, normalised to rest at four different movement amplitudes. Movement variability was also measured. Magnitude-based inferences were used to compare each amplitude.ResultsExercise at all amplitudes recruited LM and TrA more than rest, with thickness increases of approximately 5 and 1 mm, respectively. Larger amplitudes also caused increased TrA thickness, LM and TrA muscle thickness variability and movement variability. The data suggests that all amplitudes are useful for recruiting LM and TrA.ConclusionsA progressive training protocol should start in the smallest amplitude, increasing the setting once participants can maintain a consistent movement speed, to continue to challenge the motor control system.Electronic supplementary materialThe online version of this article (doi:10.1007/s00421-017-3648-3) contains supplementary material, which is available to authorized users.
