“…3 Not all studies demonstrate differences in muscleactivation pattern; however, there was a trend showing that patients with nonspecific LBP primarily activated LES during PHE. 28 Our findings suggest that the PHE may be clinically helpful for identifying altered muscle activation patterns in nonspecific LBP. Palpation for activation of the LM muscle group has demonstrated reliability and validity during the index or arm lift test, and in conjunction with performance of the PHE may provide additional clinical information.…”

“…Although the strategy of nonspecific LBP patients appears to stabilize the lumbar spine during PHE, it may impart increased or asymmetrical stresses on the spinal tissues and consequently cause low back injury or perpetuate symptoms . Not all studies demonstrate differences in muscle‐activation pattern; however, there was a trend showing that patients with nonspecific LBP primarily activated LES during PHE . Our findings suggest that the PHE may be clinically helpful for identifying altered muscle activation patterns in nonspecific LBP.…”

“…Our data from healthy individuals demonstrated no significant side-to-side differences, which is consistent with several prior studies that demonstrated no difference in muscle activity between left-and right-sided trunk muscles in healthy individuals. 23,28,29 Therefore, we averaged muscle activity data for healthy participants. However, pain location in patients with nonspecific LBP could alter lumbopelvic motion and trunk muscle activity.…”

Background Prone hip extension is used to clinically assess movement control in patients with nonspecific low back pain (LBP). Excessive lumbopelvic movements and altered muscle activation patterns are common in patients with nonspecific LBP. However, no evidence exists regarding lumbar multifidus and lumbar erector spinae muscle synergy patterns in patients with nonspecific LBP during this clinical test. Objective To determine the difference in lumbopelvic motion and change in muscle synergy between patients with nonspecific LBP and healthy individuals. Design A cross‐sectional study design. Setting University physical therapy clinic and laboratory. Participants Seven patients with nonspecific LBP (age [mean ± SD] 29 ± 5 years, 43% female, body mass index [BMI] of 25 ± 2 kg/m2, Numeric Pain Rating Scale 6 ± 2; Oswestry Disability Index 20% ± 8%) and seven age‐, sex‐, and BMI‐matched healthy individuals (mean age 28 ± 5 years, 43% female, BMI of 22 ± 2 kg/m2) were recruited. Methods Each participant performed six repetitions of prone hip extension on each side; kinematic and electromyographic data were collected simultaneously. Main Outcome Measurements Kinematic data were used to represent lumbopelvic motion, whereas electromyography (EMG) data were used to represent muscle activity. A paired t‐test was used to determine the difference in lumbopelvic motion. Principal component analysis and two‐way repeated‐measures analysis of variance were used to extract muscle synergies and identify differences in muscle synergy patterns between and within groups. Results Results demonstrated no significant group difference (P > .05) in amount of lumbopelvic motion. However, healthy individuals synergistically activate lumbar multifidus and lumbar erector spinae with 81.0% variance accounted for (VAF). Patients with nonspecific LBP had an altered synergy with independent activation of lumbar multifidus on the painful side with 32.0% VAF and the lumbar multifidus on the nonpainful side, and both lumbar erector spinae with 52.2% VAF synergistically activated. Conclusions These findings suggest that clinicians should focus on muscle activation patterns rather than the amount of lumbopelvic motion during clinical observation of prone hip extension. Level of Evidence Level III.

“…Imai et al12 ) demonstrated that lumbar stabilization exercises performed on an unstable surface enhanced trunk muscle activity, and Kim et al13 ) reported that a single-leg hold exercise stimulated greater abdominal muscle activity when performed on an unstable surface than on a stable surface. Previous findings of muscle activation patterns elicited by PHE are inconsistent because the investigators focused on back and hip muscle activity and did not consider performance on unstable surfaces14, 15 ) . Although several studies have demonstrated the benefit of performing trunk stability exercises on an unstable surface, few have investigated the effect of performing PHE on an unstable surface.…”

[Purpose] The aim of this study was to compare muscle activity of the posterior oblique sling during prone hip extension (PHE) on the floor and on a round foam roll. [Subjects] Twenty-two (11 male, 11 female) healthy volunteers were recruited for this study. [Methods] The participants performed PHE on the floor and on a round foam roll. Surface electromyography (EMG) was recorded from the contralateral latissimus dorsi (LD), contralateral erector spinae (ES), ipsilateral ES, ipsilateral gluteus maximus (GM), and ipsilateral biceps femoris (IBF). A paired t-test was used to compare muscle activity under the floor and round foam roll conditions. [Results] EMG activity of the contralateral LD, ipsilateral ES, and ipsilateral GM was significantly greater when PHE was performed on the round foam roll than on the floor. [Conclusion] Performing PHE on the round foam roll induced greater posterior oblique sling EMG activity than did exercise on the floor. These results suggest that the activation pattern of the posterior oblique sling during PHE is differs according to the type of surface (stable vs. unstable) on which it is performed.

“…Moreover, a report by Guimarães et al (2010) has cast doubt over the possibility that patients with low back pain and the healthy individuals can be distinguished only by analyzing the muscle firing order. This study suggested that it is necessary to evaluate the movement patterns in addition to the muscle activation patterns during the active prone hip extension in order to discriminate between patients with low back pain and healthy individuals (Guimarães et al, 2010).…”

Prone hip extension has been used as a self-perturbation task to test the stability of the lumbopelvic region. However, the relationship between recruitment patterns in the hip and trunk muscles and lumbopelvic kinematics remains unknown. The present study aimed to examine if the balance of hip and trunk muscle activities are related to pelvic motion and low back muscle activity during prone hip extension. Sixteen healthy participants performed prone hip extension from 30° of hip flexion to 10° of hip extension. Surface electromyography (of the gluteus maximus, semitendinosus, rectus femoris, tensor fasciae latae, multifidus, and erector spinae) and pelvic kinematic measurements were collected. Results showed that increased activity of the hip flexor (tensor fasciae latae) relative to that of hip extensors (gluteus maximus and semitendinosus) was significantly associated with increased anterior pelvic tilt during hip extension (r=0.52). Increased anterior pelvic tilt was also significantly related to the delayed onset timing of the contralateral and ipsilateral multifidus (r=0.57, r=0.53) and contralateral erector spinae (r=0.63). Additionally, the decrease of the gluteus maximus activity relative to the semitendinosus was significantly related to increased muscle activity of the ipsilateral erector spinae (r=-0.57). These results indicate that imbalance between the agonist and antagonist hip muscles and delayed trunk muscle onset would increase motion in the lumbopelvic region.
