Abstract

Abstract:

Objective To explore the immediate and short-term effects of pressure biofeedback therapy combined with Flexi-bar exercise in the sitting position on chronic non-specific low back pain (CNSLBP).

Methods From June to September, 2022, 27 CNSLBP students in Xuzhou Medical University and other universities around were randomly divided into pressure biofeedback unit (PBU) group (n = 9), Flexi-bar group (n = 9) and combined group (n = 9). On the basis of routine rehabilitation guidance, the PBU group accepted pressure biofeedback therapy, the Flexi-bar group accepted active vibration therapy, and the combined group accepted pressure biofeedback therapy and active vibration therapy, for three weeks. They were measured core stability with Stabilizer, lumbar joint repositioning error (LJRE) with iHandy, and bilateral transverse abdominis thickness and multifidus muscle cross-sectional area with ultrasonography; and assessed with Visual Analogue Scale for pain (VAS), Oswestry Disability Index (ODI) before and after treatment; and the core stability were measured immediately after the first treatment.

Results The indexes of core stability improved after the first treatment (|t| > 3.000, P < 0.05) in all groups, and improved the most in the combined group (F > 10.909, P < 0.001). All the indexes improved after three weeks of treatment (|t| > 2.604, P < 0.05), except for LJRE in PBU group; and they were the best in the combined group (|F| > 4.061, P < 0.05), except LJRE was not significantly different from the Flexi-bar group (P > 0.05).

Conclusion Pressure biofeedback therapy combined with Flexi-bar exercise in the sitting position can more effectively improve core stability and core muscles, proprioception, and pain for patients with CNSLBP.

Key words: chronic non-specific low back pain, pressure biofeedback therapy, Flexi-bar, core stability
