Case-History
A businessman and CEO of one of the largest luxury 5-star hotel groups had been living with Multiple Sclerosis (MS) since 1995.
Despite having access to some of the world’s leading neurologists, hospitals, and disease-modifying therapies across Canada, the USA, and Germany, his disease progressed from Relapsing-Remitting Multiple Sclerosis (RRMS) to Secondary Progressive Multiple Sclerosis (SPMS).
Following COVID-19 vaccination, his condition continued to worsen, although the exact cause of progression cannot be determined from a single case.
By April 2026, when he first attended SOZO Brain Center, he had been wheelchair-bound for four years and suffered from:
- Severe mobility impairment
- Progressive Secondary Progressive Multiple Sclerosis (SPMS)
- Severe lower-limb spasticity (upper motor neuron syndrome)
- Muscle weakness with upper and lower motor neuron signs
- Severe chronic neuropathic low back pain
- Debilitating fatigue
- Inability to walk independently
- Neurogenic bowel dysfunction
- Hyperactive neurogenic bladder with poor urinary control
in SOZO-Braincenter NICOSIA gets following treatments
Following an individualized multidisciplinary neuromodulation program incorporating:
- Transcranial Pulse Stimulation (TPS)
- High-Definition tDCS (corticospinal targeting)
- Transcutaneous Spinal Direct Current Stimulation (tsDCS)
- Transcutaneous Vagus Nerve Stimulation (tVNS)
- Extracorporeal Shock Wave Therapy (ESWT)
Three-Month Follow-Up – Munich International Medical Workshop
Workshop 10-11. July in Munich
The improvements reported included:
- Walking independently with a cane
- Playing football with his son and kicking a soccer ball again
- Significant improvement in balance and mobility
- Resolution of severe neuropathic low back pain
- improved bladder function with the ability to voluntarily hold urine for approximately 20 minutes
- Greater independence and improved quality of life
Every patient is unique, and outcomes vary. This case represents the experience of one individual and should not be interpreted as proof of effectiveness for all people with Multiple Sclerosis. Treatment decisions should always be made in consultation with qualified healthcare professionals.
