Impaired balance is common in neurological disorders. Cervical
dystonia is a neurological movement disorder affecting the neck. The effect of
this aberrant head posture on physical function is unknown. OBJECTIVES: To
compare balance, mobility, gait and stepping reactions between ten people with
cervical dystonia and ten control adults. METHODS: Spatiotemporal gait parameters
and walking speed were assessed using a computerised walkway. Step length and
time, time in double support and gait variability were calculated, then
normalised to gait speed. Centre of pressure path length was assessed with eyes
open and eyes closed to calculate a Romberg Quotient. Simple and choice reaction
times were measured using customised apparatus while mobility was assessed by the
timed up and go. Cervical spine range of motion was measured using a head mounted
goniometer. Self-reported scales included Falls Self Efficacy Scale and Dystonia
Discomfort Scale. RESULTS: There was a difference between groups for most outcome
measures. The timed up-and-go and walking speed was slower (both P<0.005) and the
Romberg Quotient lower (P=0.046) in cervical dystonia. People with cervical
dystonia had lower falls self-efficacy (P=0.0002). Reduced cervical range of
motion was correlated with balance, stepping reaction time and mobility (all
P<0.05). Timed up and go was positively associated with stepping reaction time
(P<0.01). Dystonia discomfort did not impact function. CONCLUSIONS: People with
cervical dystonia displayed deficits in balance, gait and stepping reactions, and
expressed higher fear of falling. Studies to further elucidate functional
limitations and their impact on activity and participation in daily life are
required.
