ABSTRACT
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.
ABSTRACT
BACKGROUND: This study was planned to evaluate the strength, proprioception, skill, coordination, and functional condition of the hand in individuals with psoriatic arthritis and to correlate disease activity with these parameters. METHODS: Fifty-six individuals (psoriatic arthritis group, n = 36; control group, n = 20) were included in the study. Evaluations were performed of disease activity with Disease Activity Score 28; grip strength with a dynamometer and pinch strength with pinch gauge dynamometers; joint position sensation with a goniometer; finger skills with a mobile application; and coordination and skill of both hands with the Purdue Pegboard test. The Michigan Hand Outcomes Questionnaire (MHQ) was used for hand functional evaluation. RESULTS: There was a significant difference between the grip and pinch strength of the psoriatic arthritis group and the control group (P < 0.05). There was no significant difference between the joint position sense measurements and the mobile application scores between the groups (P > 0.05). Purdue Pegboard scores showed a significant difference only in both hands and assembly subsections (P < 0.05). With Disease Activity Score 28, significant correlations were found between grip and pinch strength, mobile application scores, Purdue Pegboard all subsections, and left-hand joint position sense average error amount, and between MHQ and grip and pinch strength. CONCLUSIONS: This study is the first to show that psoriatic arthritis has a negative effect especially on hand strength; grip strength decreases as disease severity increases and, skill, coordination, and functionality of hand deteriorate.
