Variables Associated with Performance of an Active Limb Movement following Within-Session Instruction in People with and People without Low Back Pain

Modification of a movement pattern can be beneficial in decreasing low back pain (LBP) symptoms. There is variability, however, in how well people are able to modify performance of a movement. What has not been identified is the factors that may affect a person’s ability to modify performance of a movement. We examined factors related to performance of active hip lateral rotation (HLR) following standardized instructions in people with and people without LBP. Data were collected during performance of HLR under 3 conditions: passive, active, and active instructed. In people with LBP, motion demonstrated during the passive condition (r=0.873,P<0.001), motion demonstrated during the active condition (r=0.654,P=0.008), and gender (r=0.570,P=0.027) were related to motion demonstrated during the active-instructed condition. Motion demonstrated during the passive condition explained 76%(P<0.001)of the variance in motion demonstrated during the active-instructed condition. A similar relationship did not exist in people without LBP. The findings of the study suggest that it may be important to assess motion demonstrated during passive HLR to determine how difficult it will be for someone with LBP to modify the performance of HLR. Prognosis should be worst for those who display similar movement patterns during passive HLR and active-instructed HLR.

BACKGROUND: Distinctive features of low back pain-developers (LBPDs) as pre-clinical low back pain (LBP) population have been evidenced in three areas of alignment, muscle activation, and movement patterns. To clarify whether the reported altered functional movement patterns in chronic LBP patients result from or result in LBP disorders, LBPDs’ functional movement patterns should be investigated. OBJECTIVES: This study aimed to compare female LBPDs’ functional movement patterns with non-pain developers’ (NPDs). METHODS: Sixty female LBPDs and NPDs were recruited based on the research requirements. The Functional Movement Screen (FMS) was used to investigate movement quality. Data were compared between groups via Mann-Whitney U tests and correlation analyses examined association between pain intensity and onset during prolonged standing and the FMS score. Receiver Operating Characteristic Curves and Chi Squares were conducted to find the best cutoff points. An alpha level of p≤0.05 was used to establish statistical significance. RESULTS: LBPDs scored significantly lower, or rather worse than NPDs in the FMS composite score (12.06±1.33 vs. 16.43±1.59, U = 3, P < 0.001). Moreover, the optimal cutoff scores of≤14 on the FMS, 2 on the push-up, and 1 on the deep squat discriminated between female LBPDs and NPDs. The FMS composite score was correlated negatively with LBP intensity (r (60) = –0.724, p < 0.001) and positively with LBP onset (r (60) = 0.277, p = 0.032) during prolonged standing. Finally, the results indicated that female LBPDs presented with at least one bilateral asymmetry on the FMS had 10 times (95%CI, 2.941–34.008) and with at least two bilateral asymmetries on the FMS had 15.5 times (95%CI, 3.814–63.359) higher odds of developing LBP during prolonged standing than NPDs. CONCLUSIONS: Female LBPDs, who are at higher risk for developing LBP in the future, have significantly lower quality of functional movement patterns compared to NPDs. Moreover, the FMS appears to show promise for predicting individuals who are at risk for LBP development during prolonged standing.

BACKGROUND: Sex and gender affect responses to pain, but little is known about disability and quality of life. OBJECTIVES: To investigate the effects of sex and gender on disability and health-related quality of life (HRQOL) in patients with low back pain. METHODS: Ninety-three patients with low back pain were included in this cross-sectional survey study. Disability, HRQOL and gender identity were respectively assessed with the Oswestry Disability Index, Short Form-36 and Bem Sex Role Inventory. The participants were classified into four gender role orientations (masculinity, femininity, androgyny and undifferentiated). One-way analysis of variance was used to analyze both the sex and the gender role orientation. RESULTS: Females had higher disability than males (p< 0.05), but in gender identity, no significant difference was found. Seven domains of HRQOL were lower than the healthy norms. Males experienced greater impacts than females on vitality and mental health (p< 0.05). For gender identity, five domains of HRQOL had significant differences (p< 0.05). Masculinity orientation had the least impact on four domains (p< 0.05), while undifferentiated orientation had the largest impact on all domains. CONCLUSION: Sex and gender effects can be used to analyze disability and HRQOL in patients with low back pain. Females have higher disability, while HRQOL is greatly influenced by different gender role orientations.

Many risk factors have been identified as contributing to the development or persistence of low back pain (LBP). However, the juxtaposition of both high and low levels of physical activity being associated with LBP reflects the complexity of the relationship between a risk factor and LBP. Moreover, not everyone with an identified risk factor, such as a movement pattern of increased lumbopelvic rotation, has LBP.Objective:The purpose of this study was to examine differences in activity level and movement patterns between people with and people without chronic or recurrent LBP who participate in rotation-related sports.Design Case:Case-control study.Setting:University laboratory environment.Participants:52 people with chronic or recurrent LBP and 25 people without LBP who all play a rotation-related sport.Main Outcome Measures:Participants completed self-report measures including the Baecke Habitual Activity Questionnaire and a questionnaire on rotation-related sports. A 3-dimensional motion-capture system was used to collect movement-pattern variables during 2 lower-limb-movement tests.Results:Compared with people without LBP, people with LBP reported a greater difference between the sport subscore and an average work and leisure composite subscore on the Baecke Habitual Activity Questionnaire (F = 6.55, P = .01). There were no differences between groups in either rotation-related-sport participation or movement-pattern variables demonstrated during 2 lower-limb-movement tests (P > .05 for all comparisons).Conclusions:People with and people without LBP who regularly play a rotation-related sport differed in the amount and nature of activity participation but not in movement-pattern variables. An imbalance between level of activity during sport and daily functions may contribute to the development or persistence of LBP in people who play a rotation-related sport.
