The Efficacy of Graded Motor Imagery in Post-Traumatic Stiffness of Elbow: A Randomized Controlled Trial
Abstract
BACKGROUND
Physiotherapy improves the movement range after the onset of post-traumatic elbow stiffness and reduces the pain, which is a factor limiting elbow range of motion. However, no results have been reported for motor-cognitive intervention programs in post-traumatic elbow stiffness management. The objective was to investigate the efficacy of Graded Motor Imagery (GMI) in post-traumatic elbow stiffness.
METHODS
Fifty patients with post-traumatic elbow stiffness (18 female; mean age, 41.9±10.9 years) were divided into two groups. The GMI group (n=25) received a program consisting of left/right discrimination, motor imagery, and mirror therapy (twice a week for six weeks); the structured exercise (SE) group (n=25) received a program consisting of the range of motion, stretching, and strengthening exercises (twice a week for six weeks). Both groups received a 6-week home exercise program. The primary outcome was the Disabilities of the Arm, Shoulder and Hand (DASH). The secondary outcomes were the active range of motion (AROM), Visual Analogue Scale (VAS), Tampa Scale for Kinesiophobia (TSK), muscle strength of elbow flexors and extensors, grip strength, left/right discrimination, and Global Rating of Change. Patients were assessed at baseline, at the end of treatment (12 sessions), and a 6-week follow-up.
RESULTS
The results indicated that both GMl and SE interventions significantly improved outcomes (p<0.05). After a 6-week intervention, the DASH score was significantly…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 25 participants or records.
