Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Changes in lumbar spine bone mineral density; 6 months (before and after intervention); Bone mineral density is an indicator of evaluating the strength of human bones, with lower bone mineral density a marker of osteoporosis;Changes in lumbar spine maximum compression force; 6 months (before and after intervention); Maximum compression force is an indicator of evaluating the strength of human bones, with lower maximum compression force a marker of osteoporosis;Joint reaction force (BW); 6 months (post intervention) ;Paravertebral muscle force ; 6 months (post intervention) ;Correlation coefficient between changes in bone mineral density and joint reaction force;Correlation coefficient between changes in bone mineral density and mechanical stimulation; | — |
Secondary
| Measure | Time frame |
