Dynamic Surface Topography for Thoracic and Lumbar Pain Patients-Applicability and First Results

Area of Science:

• Biomechanical analysis
• Spinal kinematics
• Medical imaging and diagnostics

Background:

• Current back pain diagnostics rely on static spinal assessments.
• Dynamic Surface Topography (DST) offers radiation-free analysis of spinal motion under dynamic conditions.
• The applicability and data for DST in back pain patients remain largely unexplored.

Purpose of the Study:

• To investigate the feasibility and initial findings of using Dynamic Surface Topography (DST) in patients with thoracic and lumbar back pain.
• To compare spinal motion during walking in back pain patients versus a healthy reference group.

Main Methods:

• A prospective observational study involving 32 back pain patients and a healthy control group.
• Patients walked on a treadmill at four randomized speeds (2, 3, 4, 5 km/h) while undergoing DST measurements.
• Intrasegmental rotation and total spinal motion were calculated and compared between groups using statistical tests (Mann-Whitney U, Kruskal-Wallis).

Main Results:

• Back pain patients exhibited greater total segmental rotation than the healthy group at speeds of 2-4 km/h.
• Increased spinal motion was observed in patients with higher pain levels (>3 VAS) at 3 km/h.
• While average differences were small, standard deviations were large, indicating individual variability.

Conclusions:

• Dynamic Surface Topography (DST) is a viable method for assessing back pain patients who can confidently walk on a treadmill.
• DST measurements show potential for generating personalized therapeutic information for back pain management.
• Further research is warranted to fully elucidate the clinical utility of DST in this patient population.
