This study explores how electrical stimulation of paralyzed trunk and hip muscles can improve posture and function in someone with complete paralysis after a spinal cord injury. The implanted device helped stabilize the torso, which improved seated posture, breathing, and ability to reach. The implanted neuroprosthesis activated key muscles in the trunk and hips, resulting in better spinal alignment, increased lung capacity, and improved ability to resist external forces that could cause falls. The participant was also able to perform tasks such as returning to an upright seated position and rolling in bed more independently. By using electrical stimulation to provide trunk stability, the individual experienced improvements in performing daily activities and felt a greater sense of safety and independence, highlighting the potential benefits of this technology for enhancing the quality of life for individuals with tetraplegia.
Electrical stimulation can improve posture, spinal alignment and seated stability, potentially reducing the need for restrictive straps or supports.
The intervention can enhance respiratory function by improving the mechanical position of the lungs and diaphragm.
Electrical stimulation may enable individuals with tetraplegia to perform activities of daily living and personal mobility functions, such as returning to an upright position and turning in bed, more independently.
