The study authors examined the one-year postoperative answers to the last eight questions on the SRS30 among a 1,422 patient population. The researchers found:

 

1. Average preoperative SRS22R appearance score improved at one year after surgery from 2.5±0.73 to 3.62±0.84.

 

2. One year after surgery the average SRS22R activity score improved from 2.96±0.59 to 3.33±0.8.

 

3. The average SRS22R pain score jumped from 2.73±0.92 to 3.6±0.93 one year after surgery.

 

4. The average preoperative subtotal score for SRS22R was 2.56±0.66. That score improved to 3.11±0.8 one year after surgery.

 

5. The researchers found a statistically significant difference in the domain scores between the responses to the anchors, according to the report. The substantial clinical benefit scores were:

 

• Appearance: 1.6
• Activity: 0.87
• Subtotal: 0.69
• Total: 0.94

 

“These SCB thresholds can be used to quantify the clinical significance of health status change in the surgical management of adult spinal deformity,” concluded the study authors.
