•a) Patients that suffered either an ischaemic or haemorrhagic stroke (Blanton et al, 2006\) as clinically diagnosed by a medical specialist. Information on type of stroke will be obtained from the patients¿ medical records.
•b) Male and female patients from the age group 19 ¿ 84 years (The SASPI Project Team, 2004\).
•c) Patients that are in the sub\-acute phase following the stroke, are able to follow instructions (Lennon et al, 2006\) and have the capacity to provide informed consent (Loetscher et al, 2015\).
•d) Patients that presented with visual impairments and central vestibular dysfunction identified during phase 1 of the study will be recruited to participate in phase 2 of the study.

•a) Severe dementia, identified by implementing the Mini\-Mental State Examination (MMSE). (Patients must have a score of seven or higher on the MMSE) (Hafsteinsdóttir, 2005\).
•b) History of an organic disorder or major psychiatric impairment (Blanton et al, 2006\).
•c) Other co\-morbid disease or disability such as cancer or amputation that will prevent or limit assessment of the patients and their, participation or follow\-up over a period of twenty (20\) weeks (Robertson et al, 2002; Blanton et al, 2006; Lennon et al, 2006\).
•d) Positive Dix\-Hallpike test (to exclude BPPV).
•e) Dix\-Hallpike test: Because the Dix\-Hallpike test and CRT (Epley) manoeuvre require head rotation of 45° and extension of 20° to 30°; patients with a history of neck surgery, recent neck trauma, severe rheumatoid arthritis, atlanto\-axial and occipito\-atlantal instability, cervical myelopathy or radiculopathy, carotid sinus syncope, Chiari malformation and vascular dissection syndromes are excluded from the study (Herdman \& Tusa, 2007\).
•f) Participation in other pharmacological or rehabilitation intervention studies which can lead to confounding of the results of this study (Blanton et al, 2006\).
•g) Any adverse effects within the period of twenty (20\) weeks will be documented.
