“…The interest in the multifidus muscles is increasing with several studies suggesting a specific role of this muscle in the pathogenesis of back pain [9,11]. In the present study, a simple manual estimate of muscle tension gave remarkably good kappa value for the intraobserver test with a reasonably acceptable value for the inter-observer kappa.…”

Intra-observer and inter-observer agreement of the manual examination of the lumbar spine in chronic low-back pain

Examination is a cornerstone in the manual procedures leading to mobilisation/manipulation of the low back. The observer variation of the more specific segmental tests remains to be investigated. Two skilled specialists in manual medicine examined the segmental changes in the lumbar spine. The patients were unknown to the examiners and no information of the case history was given. All test results were recorded by an observer present in the room who ensured that no conversation was allowed during the examination. The primary outcome measures were the kappa values for each test. The matching was defined as acceptable (acc) within two neighbouring levels and perfect (per) on the same level. Intra-observer variation (tested in 33 patients and 10 subjects without low-back pain): The agreement between first and second segmental diagnosis examination was 70% (per) and 82% (per + acc).

“…34 Evidence for the role of ligaments in trunk stability has been shown by anatomical observations. [35][36][37] Injury to the passive subsystem (ligaments) may have important implications for spinal stability. It may increase the size of the neutral zone and enhance the demands on the active and neural control subsystems to avoid the development of segmental instability.…”

Objective: The purpose of this preliminary study was to investigate the effect of functional lumbar stabilization exercises on pain, disability, and kinesiophobia in women with menstrual low back pain (LBP). Methods: Thirty women with menstrual LBP participated in the study. Subjects were assigned to a control group (n = 10, mean age = 25.1 ± 4.7 years) and an intervention group (n = 20, mean age = 21.7±2.4 years). Treatment for the intervention group consisted of functional lumbar stabilization exercises, 10 repetitions each, 3 times a day, for 3 consecutive months. The women in the control group received no exercise and performed their regular activity daily living. Pain intensity using a Numeric Pain Scale (NPS), Oswestry Disability Index (ODI), Roland-Morris Questionnaire (RMQ), and Tampa Scale of Kinesiophobia (TSK) was collected at baseline and at the end of 3 months in both groups. Results: Statistical analysis (paired t test) revealed a significant decrease in NPS, ODI, RMQ, and TSK after treatment in the intervention group. No significant difference in NPS, ODI, RMQ, or TSK was found between pre-and postmeasurement scores in the control group. In the analysis of covariance, controlling for pretest scores, a significant difference was found between the 2 groups in the postmeasurement score of NPS (P = .01), ODI (P b .001), RMQ (P = .002), and TSK (P = .04). Conclusion: Lumbar stabilization exercises were shown to improve pain, disability, and kinesiophobia during menstrual LBP for subjects who participated in this preliminary study compared to those who did not receive the intervention.

“…Indahl et al [36] reported that some complex regulatory mechanisms of reflexes exist for control of movement of lumbar region, and also suggested that loss of the lumbar FRP in LBP patient may be due to the imbalance between the neural outputs from the damaged structure to the muscles. This imbalance in the reflex arc can lead to additional muscle activity to protect spinal structures.…”

A comparative investigation of flexion relaxation phenomenon in healthy and chronic neck pain subjects

Purpose The cervical flexion relaxation phenomenon (FRP) is a neck extensor myoelectric ''silence'' that occurs during complete cervical and lumbar flexion. In contrast to low back pain, the changes that occur during FRP in chronic neck pain (CNP) patients are still not clear. The aim of this study was to assess the characteristics of this phenomenon in the cervical region in CNP patients and controls. Methods Twenty-two women (23 ± 2.62 years) with chronic non-specific neck pain and 21 healthy women (23.4 ± 1.68 years) participated in this study. They accomplished a cervical flexion and extension from neutral position. Neck angle and surface electromyographic activity of cervical erector spinae (CES) and upper trapezius muscles were recorded. Appearance, onset and offset angle of the FRP were analysed and compared between the two groups. Results There were significant differences in the appearance of FRP between the two groups (P B 0.001). The FRP in the CES muscles was observed in 85.7 % of healthy subjects and in 36.3 % of CNP patients, and no FRP was observed in the upper trapezius. Results of this study show that the onset and offset of FRP parameters were significantly different between the two groups (P B 0.001).Conclusions The results of the present study indicate that FRP in CNP patients was seen less than the healthy subjects, and moreover the FRP period was reduced in CNP patients. Our results also suggest that the changes in FRP of CNP patients may be due to the increased CES activity in these patients.
