“…On the other hand, while the reliability of the measurement of translation, laxity and MSI in this configuration has been found to be acceptable, MSV changes over time in the individual were not, making it potentially less useful as a measure [23,25,29]. However, MSV may be helpful in investigating the therapeutic actions of motor control and strengthening exercises at an intervertebral level [30][31][32][33][34].…”

Patients with treatment-resistant nonspecific back pain have greater MSI values than controls, especially if the former have received spinal surgery. However, excessive laxity, translation and MSV are not more prevalent in these patients. Thus, MSI should be investigated as a pain mechanism and for its possible value as a prognostic factor and/or target for treatment in larger patient populations. These slides can be retrieved under Electronic Supplementary Material.

“…Investigations into the biomechanical effects of abnormal LPC show that it could be detrimental on the lower back (Tafazzol et al, 2014;Shojaei et al, 2018). Physical therapy techniques, including lumbar stabilization programs are popular treatment methods for LBP (Searle et al, 2015); however, Shahvarpour et al found a lumbar stabilization program had no significant effects on LPC and that patients retained a lower lumbar spine range of motion (compared to healthy controls) after pain and disability had decreased (Shahvarpour et al, 2017). Functional restoration programs have shown some effectiveness in correcting LPC, with LBP patients capable of achieving a normal LPC reporting less pain than patients who don't (Mayer et al, 2009).…”

“…This included studies on differences in activities of trunk muscles (Ahern et al, 1988;Paquet et al, 1994), trunk motion and lumbo-pelvic coordination (LPC) (Mayer et al, 1984;Marras and Wongsam, 1986;Porter and Wilkinson, 1997;, and spinal loads (Kumar, 1990;Neumann et al, 2001). The outcomes of such studies (i.e., the identified abnormalities in different aspects of lower back biomechanics of patients with LBP) then motivated other studies on treatments aimed at modification of such specific abnormalities in lower back biomechanics (Hoffman et al, 2011;Morrisette et al, 2014;Smith et al, 2014;Searle et al, 2015;Shahvarpour et al, 2017).…”

“…Therefore, back orthoses are not suitable for correction of the above noted abnormalities in LPC of patients with LBP that have been widely reported to be associated with a reduced lumbar motion. Similarly, exercise programs commonly employed in physical therapy have shown correlation with a reduction in LBP symptoms in chronic patients (Searle et al, 2015), but they often are ineffective at correcting abnormal LPC (Shahvarpour et al, 2017). Other physical therapy techniques have shown some effectiveness in LPC correction, with patients who are able to achieve the correction reporting lower pain ratings than those unable to correct (Mayer et al, 2009).…”

Individuals with low back pain demonstrate an abnormal lumbo-pelvic coordination compared to back-healthy individuals. This abnormal coordination presents itself as a reduction in lumbar contributions and an increase in pelvic rotations during a trunk forward bending and backward return task. This study investigated the ability of a hip orthosis in correcting such an abnormal lumbo-pelvic coordination by restricting pelvic rotation and, hence increasing lumbar contributions. The effects of the hip orthosis on the lumbo-pelvic coordination were investigated in 20 low back pain patients and 20 asymptomatic controls. The orthosis reduced pelvic rotation by 12.7 • and increased lumbar contributions by 11%. Contrary to our expectation, orthosis-induced changes in lumbo-pelvic coordination were smaller in patients; most likely because our relatively young patient group had smaller unrestricted pelvic rotations compared to asymptomatic individuals. Considering the observed capability of a hip orthosis in causing the expected changes in lumbo-pelvic coordination when there is a relatively large pelvic contribution to trunk motion, application of a hip orthosis may provide a promising method of correcting abnormal lumbo-pelvic coordination, particularly among patients who demonstrate larger pelvic rotation, that warrants further investigation.

“…After seven weeks of treatment, 60% of the patients reached normal FRR [18]. In addition, the effect of neurac sling exercise, exercise program using a Swiss ball, and stabilization exercise on FRR in CLB patients have previously been investigated [19][20][21]. Counter to low back pain (LBP), there are few pieces of evidence about the effect of therapeutic interventions on exion relaxation parameters in CNP patients.…”

Background: The effect of therapeutic exercise on cervical flexion relaxation phenomenon (FRP) is questionable. This study aimed at investigating the effect of eight weeks of cervical stability exercise on FRP, pain, and disability in NSCNP patients.Methods: This quasi-experimental study was conducted on 25 subjects with NSCNP. Surface electromyographic signals of the cervical erector spinae (CES) muscles in a sitting position were recorded before and after the intervention. The occurrence of FRP and flexion relaxation ratio (FRR) were analyzed before and after the eight weeks of cervical stability exercise. The low-load craniocervical flexion exercise was performed by the subjects in crook lying position. In addition, the intensity of pain and disability were assessed via visual analogue index (VAS) and neck disability index (NDI).Results: The FRR of CES muscles increased after the intervention. Similarly, the occurrence of FRP increased among NSCNP patients after the intervention. The average changes of VAS, NDI, and FRR were not associated with gender and duration of pain. Moreover, VAS and NDI scores significantly decreased after the intervention. Conclusions: Flexion relaxation phenomenon can be improved via specific stability exercises. The improvement of flexion relaxation phenomenon apparently can pain and disability.
