Abstract:
Objective:To analyze the contractile properties of the lumbar erector spinae in patients with chronic nonspecific low back pain (CNLBP), and to explore their correlation with pain and dysfunction. Methods:From January to June, 2020, 24 patients with CNLBP in the outpatient and the ward of geriatric rehabilitation medicine department and 26 asymptomatic volunteers were included. Their contractile properties of the lumbar erector spinae were measured with tensiomyography, including maximum radial muscle displacement (Dm), contraction time (Tc), delay time (Td), sustain time (Ts), half-time relaxation (Tr) and lateral symmetry (LS). The contraction velocity (VC) was calculated. Potential associations of tensiomyography parameters to Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI) were assessed using correlation analysis. Results:No significant differences were found in Td, Ts, Tc, Tr and LS between two groups (P > 0.05). Dm and Vc were significantly lower in both sides of CNLBP group than in the control group (t > 2.058, P < 0.01). Dm or Vc were not correlated with VAS and ODI (P > 0.05). Conclusion:Erector spinae are stiff and fatiguable in patients with CNLBP, however, they are not associated with pain and dysfunction. Tensiomyography could be used for accurate diagnosis and treatment of CNLBP.
