Cerebellar ataxia is a complex motor disturbance that involves the planning and execution of movements and reduces movement accuracy and co-ordination. The quantification of ataxic signs is commonly realised through visual examination of motor tasks performed by the patient and assignment of scores to specific items composing the international co-operative ataxia rating scale (ICARS). The present work studied an experimental procedure to characterise specific aspects of motor disturbances in… 
Robotic and clinical evaluation of upper limb motor performance in patients with Friedreich’s Ataxia: an observational study
TLDR
Results suggest that outcome measures obtained by means of robotic devices can improve the sensitivity of clinical evaluations of patients’ dexterity and can accurately and efficiently quantify changes over time in clinical trials, particularly when functional scales appear to be no longer sensitive.
Smoothness of movement in idiopathic cervical dystonia
TLDR
Poor smoothness is a motor disturbance independent of movement amplitude and speed in cervical dystonia and should be assessed when evaluating this disease, its progression, and treatments.
Quantitative evaluation of functional limitation of upper limb movements in subjects affected by ataxia
TLDR
The aim of this study was to quantitatively characterize functional changes in upper limb movements in ataxic patients, using an optoelectronic system for objective measurements.
Coordination Tests in Persons With Acute Central Nervous System Pathology: Assessment of Interrater Reliability and Known-Group Validity
TLDR
These tests are recommended for use when examining patients with acute neurologic pathology from a vascular lesion or tumor, and require only a stopwatch to complete, and were performed differently between groups with and without coordination deficits.
Dynamic Cerebrospinal Fluid Flow on MRI in Cortical Cerebellar Atrophy and Multiple System Atrophy-cerebellar Type.
TLDR
The present CSF flow study showed for the first time that Vheight and Vmin revealed good correlations with the disease duration in the MSA-C patients, suggesting that this particularCSF flow analysis may be a new surrogate marker for differentiating both types of cerebellar ataxia.

Target board test for the quantification of ataxia in tremulous patients
TLDR
The TBT provides simple quantitative objective measurements of upper limb ataxia and measuring Dysmetria in the presence of tremor, and correlated significantly with dysmetria, dysdiadochokinesia, kinetic tremor and (inversely) with the finger-tapping test.
Measuring ataxia: quantification based on the standard neurological examination.
TLDR
Results indicate that tests 1, 2 and 4 are sensitive for the detection of ataxia and of changes in its severity and that the test-retest repeatability was excellent.
Bradykinesia akinesia inco-ordination test (BRAIN TEST): an objective computerised assessment of upper limb motor function
TLDR
The BRAIN test assesses speed, accuracy, and rhythmicity of upper limb movements regardless of their physiological basis and correlate well with clinical rating scales in Parkinson’s disease and cerebellar dysfunction.
Gait in patients with cerebellar ataxia
TLDR
The gait pattern of patients with cerebellar degeneration shows incoordination similar to that previously described for their multijoint limb motion.
Typical features of cerebellar ataxic gait
TLDR
Typical features of gait in CD are reduced cadence with increased balance related variables and an almost normal range of motion (with increased variability) in the joints of the lower extremity.
Comparative analysis of gait in Parkinson's disease, cerebellar ataxia and subcortical arteriosclerotic encephalopathy.
TLDR
Whereas the findings in patients with Parkinson's disease can be explained as a reduction of force gain, the observations for patients with ataxia and subcortical arteriosclerotic encephalopathy reflect an altered spatiotemporal gait strategy in order to compensate for instability.
Kinetic tremor in a reach‐to‐grasp movement in Parkinson's disease
TLDR
The authors' results confirm similarities between the tremor at rest and the oscillations during a sustained postural task in classic parkinsonian tremor, which seems to be generated by basal ganglia oscillators.
