The level of his injury is at C6 – he preserved function below that neurologic level. He cannot walk and he also has some impairment in the arms and hands. He is still able to use a manual wheelchair with his upper limbs’ ability. Lucas is interested in the HandbikeBattle coming up in 2024. This organized event boosts self-confidence and fitness in those who have completed rehabilitation after an injury. Lucas wishes to train this year so that he can think of going to that event. Lucas may need a power-assisted handcycle for the event, but will train with you to be properly prepared. He has not been as active in the past 5 years as he dedicated himself to his work and family and his recovery in rehab.

The spells continued and Connie became able to predict the attacks, telling her parents that her head hurt before the spells Her parents took her to a neurologist, who checked Connie’s heart and diagnosed Long Q-T syndrome with deafness. This condition was also known as Lange-Nielsen syndrome. The physician explained that this is a severe form of long-QT syndrome, which is an inherited heartbeat irregularity that can be fatal. Seven genes can cause long Q-T syndrome. The Winslows (parents) visited a medical geneticist, who discovered that each had a mild, heartbeat irregularity that did not produce symptoms.
