Abstract

ABTRACT: Stroke is a leading cause of disability in adults, with upper limb motor impairments being one of the most common complications. These impairments can result in decreased hand dexterity, significantly affecting patients' ability to perform daily activities such as eating, dressing, and completing other tasks. This study aimed to evaluate the effectiveness of Repetitive Peripheral Magnetic Stimulation (rPMS) in improving hand dexterity in subacute post-stroke patients compared to standard rehabilitation. A randomized controlled experimental design with a pre-post method was employed in two groups under a single-blind protocol. Twenty-six subacute post-stroke patients meeting the inclusion criteria were divided into two groups: a treatment group receiving rPMS alongside standard rehabilitation and a control group undergoing standard rehabilitation only. rPMS was administered in 10 sessions over 30 days, with a frequency of 2–3 sessions per week. Hand dexterity was assessed using the Box and Block Test (BBT) before and after the intervention. Results revealed that both groups demonstrated significant improvements in hand dexterity following the interventions. In the treatment group, the median BBT score increased from 34 to 40 blocks per minute, while in the control group, it rose from 23 to 30 blocks per minute. Statistical analysis using the Wilcoxon Signed Ranks test and paired t-tests indicated a significant positive effect of rPMS. However, comparative analysis between the groups did not reveal a statistically significant difference in hand dexterity improvement. This study highlights the potential of rPMS as an effective adjunct modality in rehabilitating subacute post-stroke patients, particularly for motor recovery of the upper limbs
