“…In the present study, the computed model activities of lumbo-pelvic muscles during FRED exercise are in line with previous physiological studies [10,14] and reinforce the findings that the combination of lower-limb movement and weight-bearing in a constant and slow motion shows great potential to activate these muscles [7,10,14]. The results from the FRED oneG model indicated that all of the investigated lumbo-pelvic muscles are constantly activated throughout the whole exercise cycle.…”

“…Previous terrestrial studies with the FRED reported promising results, indicating that it could be a valid tool to be used in people with deficits of deep spinal and 'anti-gravity' muscles [7,10,14]. In the present study, the computed model activities of lumbo-pelvic muscles during FRED exercise are in line with previous physiological studies [10,14] and reinforce the findings that the combination of lower-limb movement and weight-bearing in a constant and slow motion shows great potential to activate these muscles [7,10,14].…”

“…This feature constitutes a postural challenge to the user because of the need to actively control the movement of the legs while maintaining a stable trunk. 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].…”

“…Recently, a novel exercise device (the Functional Re-adaptive Exercise Device, or the FRED, Figure 1) has been developed [10] that showed promising results to immediately increase lumbopelvic stability during movement in healthy terrestrial individuals, as indicated by a decreased range of hip rotation in the transverse plane [14]. The device is similar in action to an elliptical trainer but requires the user to work against almost no resistance in order to move the feet.…”

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.

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.
