Prevalence of the various neurological gait disorders.

The table lists No (#) and Total No (§). No (#) stands for gait disorders, which were single entities in 81 subjects and multiple gait disorders due to combinations of different entities in 36 subjects. Total No (§) stands for the total number of subjects presenting with a specific gait disorder. For the subjects with multiple gait disorders their contributors are listed additionally in the legend (see a). E.g. there are 22 subjects who presented with sensory ataxia as a single neurological gait disorder [i.e. No (#)] and another 24 subject with a sensory ataxic gait in combination with other neurological gait disorders adding up to a total of 46 subjects with this gait abnormality [i.e. Total No (§)].Abbreviations: GD, gait disorders.
aContributors to multiple neurological GD (No.): Sensory ataxic (24), higher level (22), parkinsonian (15), paretic/hypotonic (8), cerebellar ataxic (3), vestibular ataxic (2), dyskinetic (3), spastic (1);
bDiagnosed in the presence of neuropathic symptoms (numbness, altered sensation, or pain in the feet) and neurologic signs (decreased ankle reflexes, decreased distal sensation, and disturbed vibration sense) according to current criteria [30];
cSubjects with a parkinsonian syndrome not fulfilling criteria for definite Parkinson’s disease [13];
dWith core gait features of a slow, wide base gait with short steps like ‘walking on ice’ [3].
