Background: Research on the multi-faceted characteristics of persistent severe acute lower back pain (LBP) resulting from acute vertebral compression fractures (VCFs) is lacking.
Objective: To investigate the psychological and functional status of older patients with persistent severe acute LBP after conservative treatment of VCFs.
Methods: This prospective study included women aged 50 years and older who had acute VCFs and were admitted to the hospital.
Osteoporotic fractures are common among older people, and hip fractures (HF) can be devastating. Surgery is indicated for most cases of HF, and chronic persistent postoperative pain is likely to occur. This study investigated the multifaceted factors related to persistent pain occurring during the acute phase and subacute phase of recovery after HF surgery.

Design: The groups included male Wistar rats (controls), rats with both bilateral ankle joints immobilized with plaster casts for 4 wks (immobilization [IM]), and rats in which twitch contraction of the soleus muscle was induced by lumbar magnetic stimulation for 4 wks of immobilization (twitch contraction [TC]). Group differences in ankle dorsiflexion range of motion, collagen content as determined by hydroxyproline assay, and the expression of fibrosis-related genes as determined by reverse transcription-polymerase chain reaction (hypoxia inducible factor 1α, α-smooth muscle actin, and types I and III collagen) in the soleus muscle were examined after the 4-wk-long experiment.
