Early rehabilitation targeting cognition, behavior, and motor function after lumbar fusion: a randomized controlled trial.

STUDY DESIGN

Open label randomized controlled trial with 3-, 6-, 12-month, and 2- to 3-year follow-up.

OBJECTIVE

To investigate the effectiveness of a psychomotor therapy focusing on cognition, behavior, and motor relearning compared with exercise therapy applied during the first 3 months after lumbar fusion.

SUMMARY OF BACKGROUND DATA

Postoperative management after lumbar fusion commonly focuses on analgesic pain control and activities of daily living. After 3 months, exercise therapy is often implemented. No randomized controlled trial has investigated early rehabilitation techniques conducted during the first 3 months after surgery.

METHODS

The study recruited 107 patients, aged 18 to 65 years, selected for lumbar fusion because of 12 months of symptomatic spinal stenosis, spondylosis, degenerative/isthmic spondylolisthesis, or degenerative disc disease. The exercise therapy group received a home program focusing on pain contingent training of back, abdominal, and leg muscle functional strength and endurance, stretching, and cardiovascular fitness. The psychomotor therapy group received a home program and 3 outpatient sessions focusing on modifying maladaptive pain cognitions, behaviors, and motor control.Rated questionnaires investigating functional disability, pain, health-related quality of life, functional self-efficacy, outcome expectancy, fear of movement/(re)injury, and coping were assessed at 3, 6, 12 months, and 2 to 3 years after surgery.

RESULTS

Follow-up rates were 93% at 12 months and 81% at 2 to 3 years after surgery. Psychomotor therapy improved functional disability, self-efficacy, outcome expectancy, and fear of movement/(re)injury significantly more than exercise therapy at respective follow-up occasions. Similar results occurred for pain coping but group differences were nonsignificant at 2 to 3 years follow-up. Potentially clinical relevant higher reoperation rates occurred after psychomotor therapy but rates were within normal ranges.

CONCLUSION

The study shows that postoperative rehabilitation can be safely implemented during the first 3 months after lumbar fusion and should include measures to modify psychological as well as motor functions.
