Effect of Graded Motor Imagery Combined With Repetitive Transcranial Magnetic Stimulation on Upper Extremity Motor Function in Stroke Patients: A Randomized Controlled Trial.

To investigate the efficacy of graded motor imagery therapy (GMI) and repetitive transcranial magnetic stimulation (rTMS) on upper extremity function alone and in combination in patients with stroke. This was a prospective randomized controlled trial. A rehabilitation hospital. Participants (N=56) were randomized into GMI (n=19), rTMS (n=18), or combined groups (n=19). There were 2 interventions: (1) 20 minutes of 1 Hz rTMS. (2) 30 minutes of GMI. In addition to this, all participants receive conventional rehabilitation including 120 minutes of physical therapy and occupational therapy daily. All treatments were administered once a day, 5 days a week, for 4 weeks. The Fugl-Meyer assessment of upper extremity (FMA-UE), Action Research Arm Test (ARAT), modified Barthel Index (MBI), motor activity log (MAL), and motor evoked potential (MEP) were assessed in a blinded manner at baseline and 4 weeks after treatment, respectively. The primary endpoint was the improvement from baseline in FMA-UE for stroke patients at 4 weeks. After 4 weeks of treatment, the FMA-UE scores in the GMI, rTMS, and combined groups were higher than those at baseline assessment, with statistically significant differences among the 3 groups (P =.009). The efficacy of the combined group was significantly better than that of the GMI and rTMS groups (P =.015, P =.043, respectively). In the motor activity log-amount of use (MAL-AOU) score, the efficacy of the combined group was better than that of the rTMS group (P =.035). Both GMI and rTMS were effective in improving upper extremity function in patients with stroke, but the combination of the 2 techniques was more effective. However, GMI was better than rTMS in improving the interest of stroke patients in active training. [ABSTRACT FROM AUTHOR]
