Scientists in Switzerland have developed a spinal implant system enabling paraplegic patients to walk and cycle. The system includes a gel pack with electric leads tailored for each patient, implanted on the spinal cord. Powered by a pacemaker in the abdomen, it connects wirelessly to a tablet. Patients use the software to choose activities like standing, walking, or cycling. The software sends instructions to the pacemaker, which stimulates nerves to control leg and trunk muscles, allowing movement.

What is the primary function of the spinal implant system developed by scientists in Switzerland?

• To allow paraplegic patients to walk and cycle

• To cure spinal injuries completely

• To enhance brain activity

• To improve heart function

Where is the pacemaker, which powers the spinal implant system, implanted?

• In the abdomen

• In the chest

• In the leg

• In the brain

How do patients select the activity they want to perform using the spinal implant system?

• By voice command

• By pressing a button on the implant

• By using software on a tablet

• By using a remote control

What role does the software play in the spinal implant system?

• It diagnoses spinal injuries

• It provides nutritional advice

• It sends instructions to the pacemaker

• It monitors heart rate

What is the result of the electrical pulses sent by the pacemaker in the spinal implant system?

• They enhance memory

• They increase blood circulation

• They stimulate nerves to control muscles

• They cause pain relief
