It was all right there IF you read it
CFT was effective for the primary outcome of activity limitation and all of the secondary outcome measures. The large effect sizes persisted to the end of the follow-up period (12 months), which is unusual in chronic low back pain. The use of wearable sensor biofeedback did not add to effectiveness. CFT was also much more cost-effective from a societal perspective than usual care.
CFT addresses pain-provocative movement patterns that contribute to low back pain, such as protective muscle guarding and movement avoidance. Wearable movement sensors enable clinicians to easily measure such movements and explore their relationship to pain, both in the clinical setting and during patients' normal activities at work and recreation. Via biofeedback, this technology can help patients to develop an awareness of how they move during normal activities, enhancing their ability to correct unhelpful movement habits. A pilot randomised controlled trial11 (n=112) of patients with chronic low back pain showed that individualised rehabilitation, which included the wearing of wireless movement sensors, resulted in large and sustained clinical improvements compared with guideline-recommended treatment (12-month SMDs 0·5–1·0). No trials have investigated whether wearable sensors can enhance the effects of CFT.
