Background: The aim was to investigate the effect of graded motor imagery (GMI) added to rehabilitation on pain,
functional performance, motor imagery ability, and kinesiophobia in individuals with total knee arthroplasty (TKA).
Methods: Individuals scheduled for unilateral TKA were randomized to one of two groups: control (traditional
rehabilitation, n = 9) and GMI (traditional rehabilitation + GMI, n = 9) groups. The primary outcome measures
were the visual analogue scale and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC).
Secondary outcome measures were knee range of motion, muscle strength, the timed up and go test, mental
chronometer, Movement Imagery Questionnaire-3, lateralization performance, Central Sensitization Inventory, Pain
Catastrophizing Scale, and Tampa Kinesiophobia Scale. Evaluations were made before and 6 weeks after surgery.
Results: Activity and resting pain were significantly reduced in the GMI group compared to the control group (P
< 0.001 and P = 0.004, respectively). Movement Imagery Questionnaire-3 scores and accuracy of lateralization
performance also showed significant improvement (P = 0.037 and P = 0.015, respectively). The Pain Catastrophizing
Scale and Tampa Kinesiophobia Scale scores were also significantly decreased in the GMI group compared to the
control group (P = 0.039 and P = 0.009, respectively). However, GMI did not differ significantly in WOMAC scores,
range of motion, muscle strength, timed up and go test and Central Sensitization Inventory scores compared to the
control group (P > 0.05).
Conclusions: GMI improved pain, motor imagery ability, pain catastrophizing, and kinesiophobia in the acute period
after TKA.
