Summary
Forward head posture in stroke survivors is linked to poorer seated postural control and increased kyphosis. Improved postural control correlates with better upper extremity recovery after stroke.
Area of Science:
- Rehabilitation Medicine
- Biomechanical Analysis
- Neuroscience
Background:
- Postural alignment and control are critical for functional recovery after stroke.
- Impaired seated posture is common in stroke survivors, impacting daily activities.
- Photogrammetry offers a quantitative method to assess postural alignment.
Purpose of the Study:
- To investigate the correlation between seated postural alignment and postural control in individuals post-stroke.
- To identify specific postural deviations associated with functional deficits in sitting.
Main Methods:
- A cross-sectional study involving 45 acute and sub-acute stroke patients.
- Seated postural alignment measured using photogrammetry and MB Ruler software.
- Seated postural control assessed with the Function in Sitting Test (FIST).
- Spearman's Rank Correlation coefficient used for statistical analysis.
Main Results:
- Moderate positive correlation between spinal angles and postural alignment.
- Strong negative correlation observed between cranio-vertebral angle and kyphosis.
- Seated postural control (FIST) showed moderate positive correlation with cranio-vertebral angle.
- FIST demonstrated a strong positive correlation with the Brunnstrom stage of upper extremity recovery.
Conclusions:
- Forward head posture in sitting is directly correlated with poorer seated postural control post-stroke.
- Increased kyphosis is inversely related to forward head posture in sitting.
- Seated postural control is positively associated with upper extremity recovery stage in stroke survivors.
