Objective. Trunk compensations do not allow the upper limb to use its full potential to perform functional activities. Therefore, the objective of this study was analyzing the effects of movement retention and induction therapy (TRIM) with trunk and upper limb stabilization in hemiparetic patients following a stroke. Method. This was a clinical pilot study with 18 individuals with sequelae from a stroke were randomly assigned to one of three groups: a control group (CG), an experimental TRIM group without trunk restriction (GET), and an experimental TRIM group with trunk restriction (GETT). The GET and GETT groups underwent TRIM therapy based on the Shaping protocol for ten consecutive sessions, lasting 1h each, over 2 weeks. Fugl-Meyer Sensory-Motor Function Assessment Scale (FAS), the Upper Extremity Activity Inventory (MAL), surface electromyography (EMG) of the elbow flexors, extensors, and superficial wrist flexors, as well as goniometric measurements of the upper limb were utilized for evaluation. Results. Significant differences were observed over time in the GET and GETT groups for the total scores on the FAS and MAL scales, as well as in the range of motion for shoulder flexion (p<0.05). No significant differences were found for the EMG variables. Conclusion. TRIM combined with trunk stabilization did not exhibit any significant effects on functional, sensorimotor activities, or EMG and range of motion variables when comparing different groups.
