Feasibility of Measuring Vertical Perception in Acute Stroke

Lateropulsion will be assessed using the Scale for Contraversive Pushing (SCP). It involves observation of the posture of the participant in sitting and standing. Scores are assessed in sitting and standing giving a maximum score of 6.

Neglect will be assessed using the Catherine Bergego Scale. The scale is a 10-point scale with each item scored between 0 (no neglect) and 3 (severe neglect). It involves observation of a participant completing daily activities such as eating, dressing and walking.

"The bucket test involves the patient being sat upright and looking into a translucent bucket with the bucket covering their complete field of vision. On the inside of the bucket on the bottom is a dark straight line. On the outside of the bottom of the bucket is a matching dark line, the bottom of the bucket is divided into degrees with the zero-degree line being equivalent to the line inside the bucket. For measurement the bucket will be randomly rotated right or left by the examiner to 45 degrees and then slowly rotated back to the zero-degree position. Patients will signal when they estimate the inside bottom line to be truly vertical by saying stop or by raising their non-paretic hand."
