About

The goal of this observational study is to analyze how spinal alignment changes when walking compared to standing still in adults aged 50 to 80 years who have sagittal imbalance. The main questions we aim to answer are:

  1. Do patients with radiological parameters indicative of sagittal imbalance experience a statistically significant deterioration in sagittal balance during walking compared to a control group?
  2. Do radiographs taken after six minutes of walking provide comparable results to dynamic measurements during the walking test?
  3. Do patients with a greater deterioration in sagittal balance during walking show poorer clinical self-assessment scores?
  4. Is there a significant correlation between parameters obtained using established diagnostic methods and the degree of sagittal balance deterioration during walking?

Participants will be divided into two groups: patients with radiological indicators of sagittal imbalance and a control group of healthy individuals with back pain of similar age. Participants will:

  1. Complete questionnaires about their back pain and mobility.
  2. Have X-ray images taken of their spine before and after walking for six minutes.
  3. Undergo muscle strength tests and gait analysis using motion capture and electromyography (EMG) to monitor muscle activity while walking.
