Troyer syndrome
MONDO:0010156Autosomal recessive spastic paraplegia type 20 (SPG20) is a type of complex hereditary spastic paraplegia characterized by an onset in infancy of progressive spastic paraparesis associated with distal amyotrophy, psuedobulbar palsy, motor and cognitive delays, mild cerebellar signs (dysarthria, dysdiadochokinesia, mild intention tremor), short stature and subtle skeletal abnormalities (pes cavus, mild talipes equinovarus, kyphoscoliosis). SPG20 is due to mutations in the SPG20 gene (13q13.1), which encodes the protein spartin.
Also known as: SPG20, Troyer syndrome, autosomal recessive spastic paraplegia type 20, childhood-onset spastic paraparesis-distal muscle wasting syndrome, spastic paraplegia 20 (Troyer syndrome), Cross-McKusick syndrome, spastic paraparesis, childhood-onset, with distal muscle wasting, spastic paraplegia 20

Can ultrasound make botox injections more precise for stiff muscles?
Disease control Recruiting nowThis trial tests whether using ultrasound to guide botulinum toxin injections into spastic leg muscles works better than the standard method of relying on touch and anatomical landmarks. Researchers will give 40 adults with spastic paraplegia two rounds of injections, one with ea…
