Purpose: To investigate the association between acute pain trajectory over one week and patient-reported outcomes (PRO) at 6-months following lumbar surgery in patients with lumbar degenerative disease (LDD).
Methods: Two hundred and fifty-five subjects with LDD who received surgical treatment at our hospital between April 2019 and March 2022. Acute pain trajectory was measured using a pain trajectory calculator to determine an approximate line using the linear least squares method based on pain intensity on postoperative days 1, 3, 5, and 7.
Study Design: This is a prospective cohort study.
Purpose: The present study aimed to investigate the effects of residual pain after fusion surgery for lumbar degenerative diseases on quality of life (QOL).
Overview Of Literature: Residual symptoms after spinal surgery often restrict patients' activities of daily living and reduce their QOL.
Purpose: The purpose of the present study was to investigate the association between quantitatively assessed trunk extensor strength and gait-induced back pain (GIBP) in patients with adult spinal deformity (ASD).
Methods: Ninety-five patients with ASD aged ≥ 50 years who were admitted to our hospital between April 2018 and March 2023 were included in the study. GIBP was evaluated through a 6-minute walking test (6MWT), with GIBP being defined as the occurrence of back pain during the evaluation and inability to complete the test.
Article Synopsis
- - The study investigated how changes in pelvic anteversion during walking affect the physical function and walking ability of elderly patients with adult spinal deformity (ASD).
- - It involved 54 patients aged 50 and older, comparing their 6-minute walking distance (6MWD) and hip extensor strength based on their pelvic anteversion categorization into small and large groups.
- - Results showed that patients with larger pelvic anteversion had significantly lower walking ability (measured by 6MWD) and hip extensor strength, emphasizing the need for evaluating movement in addition to radiographic assessments for ASD patients.
Article Synopsis
- - The study investigates how dynamic alignment of the spine and pelvis during walking relates to lumbar function in patients with lumbar spinal stenosis (LSS), focusing on daily life performance.
- - Researchers evaluated lumbar function using the Oswestry Disability Index (ODI), muscle strength assessments, and alignment during gait in 35 preoperative LSS patients, finding significant correlations between ODI scores and various physical metrics.
- - Findings indicate that patients with weaker trunk or hip muscles, greater pelvic tilt, or reduced spinal flexion during gait experience lower lumbar function in daily life, with specific alignment metrics significantly impacting the ODI score.
