Table 1 Peripheral nerve involvement assessed by nerve conduction studies (NCS) in HSP patients

From: Electrophysiological characterisation of motor and sensory tracts in patients with hereditary spastic paraplegia (HSP)

Nerve N Percentage of patients with abnormal
   NCS DML NCV Amplitude F wave latency
Motor tibial nerve 128 33.9% 17.2% 22.7% 10.2% 8.7%
Motor ulnar nerve 128 23.8% 11.8% 4.7% 0.8% 15.9%
Sensory sural nerve 128 24.2% - 21.9% 14.8% -
Sensory radial nerve 100 36.0% - 17.0% 31.0% -
  1. N: number of patients examined, DML: distal motor latency, NCV: nerve conduction velocity.
