Background: The continuous co-contraction of the trunk muscles through trunk stabilization exercises is important to patients with lumbar spinal stenosis (LSS). However, intentional abdominal muscle contraction (IAMC) for trunk stabilization has been used only for specific training in the treatment room. Objects: The purpose of this study was to provide feedback to adults with LSS to enable IAMC during activities of daily living (ADLs). Methods: The participants with spinal stenosis were divided into an experimental group of 15 adults and a control group of 16 adults. Electromyographic signals were measured while the subjects kept their both hands held up at 90°. The measured muscles were the rectus abdominis (RA), external oblique (EO), internal oblique (IO), and erector spinae (ES). Pelvic tilt was measured using a digital pelvic inclinometer. The degree of pain was measured using the visual analogue scale (VAS) and functional capacity was measured using the Korean version of the Oswestry disability index (KODI). Results: While the experimental group showed statistically significantly higher activities in the RA, EO, and IO after the intervention compared with the control group. Pelvic tilt was significantly decreased only in the experimental group. Both the experimental and control groups exhibited statistically significant declines in the VAS and KODI (p<.01). In terms of the levels of changes, the experimental group exhibited a statistically significant larger decline only in the VAS and the pelvic tilt when compared with the control group (p<.05). Conclusions: The subjects could stabilize their trunks, and relieve their pain and dysfunctions and reduce pelvic tilt by learning abdominal muscle contraction during ADLs. The combination of therapeutic exercises and IAMC may have greater effects on patients with LSS.
