“…Although the knowledge surrounding proprioception is relatively limited because it is such a complex function, several studies have found that proprioceptive deficits in individuals with LBP might contribute to a lack of stability [8,33,34]. Another explanation for decreased balance performance in LBP subjects might be altered muscle function.…”

Even though a number of studies have evaluated postural adjustments based on kinematic changes in subjects with low back pain (LBP), kinematic stability has not been examined for abnormal postural responses during the one leg standing test. The purpose of this study was to evaluate the relative kinematic stability of the lower extremities and standing duration in subjects with and without chronic LBP. In total, 54 subjects enrolled in the study, including 28 subjects without LBP and 26 subjects with LBP. The average age of the subjects was 37.8 ± 12.6 years and ranged from 19 to 63 years. The outcome measures included normalized holding duration and relative kinematic stability. All participants were asked to maintain the test position without visual input (standing on one leg with his/her eyes closed and with the contra lateral hip flexed 90°) for 25 s. The age variable was used as a covariate to control confounding effects for the data analyses. The control group demonstrated significantly longer holding duration times (T = -2.78, p = 0.007) than the LBP group (24.6 ± 4.2 s vs. 20.5 ± 6.7 s). For the relative kinematic stability, there was a difference in dominance side (F = 9.91, p = 0.003). There was a group interaction between side and lower extremities (F = 11.79, p = 0.001) as well as an interaction between age and dominance side (F = 7.91, p = 0.007). The relative kinematic stability had a moderate negative relationship with age (r = -0.60, p = 0.007) in subjects without LBP. Clinicians need to understand the effects of age and relative stability, which decreased significantly in the single leg holding test, in subjects with LBP in order to develop effective rehabilitation strategies.

“…There are receptors responsible for this information which could be affected by dysfunction in the lumbar spine [7]. Accordingly, subjects with LBP may have altered postural control and balance deficits as well as reduced proprioception in the spine, which have been reported in several studies [2,3,7,8].…”

“…Muscle vibration, with a frequency of 70 Hz and amplitude of approximately 0.5 mm, was initiated 15 s after the start of the trial for the duration of 15 s. Each trial lasted for 60 s, with subjects standing on the force plate for 5 s before the trial started. These characteristics were proven to induce a significant effect on CoP position, with a limited number of subjects losing their balance during vibration (Brumagne et al 2004). The same procedure was repeated in trials 7, 8 and 9 with subjects standing on the foam surface.…”

“…This lengthening illusion under vibration will cause corrective displacement of the center of mass, related to the amount in which the central nervous system uses these signals for postural control. For example, when triceps surae muscles are vibrated in standing, a backward shift in CoP takes place if the central nervous system is using these signals for postural control (Brumagne et al 2004;Crowe and Matthews 1964). This displacement decreases when persons are placed on foam (Brumagne et al 2008) or on a wobble board (Ivanenko et al 1999).…”

Laboratory study using a repeated measures design. The aim of this study was to determine if ankle proprioception is targeted in exercises on unstable surfaces. Lateral ankle sprain (LAS) has recurrence rates over 70%, which are believed to be due to a reduced accuracy of proprioceptive signals from the ankle. Proprioceptive exercises in rehabilitation of LAS mostly consist of balancing activities on an unstable surface. The methods include 100 healthy adults stood barefoot on a solid surface and a foam pad over a force plate, with occluded vision.Mechanical vibration was used to stimulate proprioceptive output of muscle spindles of triceps surae and lumbar paraspinal musculature. Each trial lasted for 60 s; vibration was applied from the 15th till the 30th second. Changes in mean velocity and mean position of the center of pressure (CoP) as a result of muscle vibration were calculated. Results show that on foam, the effect of triceps surae vibration on mean CoP velocity was significantly smaller than on a solid surface, while for paraspinal musculature vibration the effect was bigger on foam than on solid surface. Similar effects were seen for mean CoP displacement as outcome. Exercises on unstable surfaces appear not to target peripheral ankle proprioception. Exercises on an unstable surface may challenge the capacity of the central nervous system to shift the weighting of sources of proprioceptive signals on balance.

“…The central nervous system (CNS) must identify and selectively focus on the sensory inputs (visual, vestibular, proprioceptive) that provide the functionally most reliable signals [1]. Muscle fatigue may decrease the reliability of the proprioceptive signals [2] and therefore the CNS might down-weight this sensory input and/or up-weight proprioceptive signals of other muscles to control posture [3,4].…”

The effect of acute back muscle fatigue on postural control strategy in people with and without recurrent low back pain

Back muscle fatigue decreases the postural stability during quiet standing, but it is not known whether this fatigue-induced postural instability is due to an altered proprioceptive postural control strategy. Therefore, the aim of the study was to evaluate if acute back muscle fatigue may be a mechanism to induce or sustain a suboptimal proprioceptive postural control strategy in people with and without recurrent low back pain (LBP). Postural sway was evaluated on a force platform in 16 healthy subjects and 16 individuals with recurrent LBP during a control (Condition 1) and a back muscle fatigue condition (Condition 2). Back muscle fatigue was induced by performing a modified Biering-Sørensen test. Ankle and back muscle vibration, a potent stimulus for muscle spindles, was used to differentiate proprioceptive postural control strategies during standing on a stable and unstable support surface, where the latter was achieved by placing a foam pad under the feet. Ankle signals were predominantly used for postural control in all subjects although, in each condition, their influence was greater in people with LBP compared to healthy subjects (p \ 0.001). The latter group adapted their postural control strategy when standing on an unstable surface so that input from back muscles increased (p \ 0.001). However, such adaptation was not observed when the back muscles were fatigued. Furthermore, people with LBP continued to rely strongly on ankle proprioception regardless of the testing conditions. In conclusion, these findings suggest that impaired back muscle function, as a result of acute muscle fatigue or pain, may lead to an inability to adapt postural control strategies to the prevailing conditions.
