Balance is a term frequently used by health professionals working in a wide variety of clinical specialities. There is no universally accepted definition of human balance, or related terms. This article identifies mechanical definitions of balance and introduces clinical definitions of balance and postural control. Postural control is defined as the act of maintaining, achieving or restoring a state of balance during any posture or activity. Postural control strategies may be either predictive or reactive, and may involve either a fixed-support or a change-in-support response. Clinical tests of balance assess different components of balance ability. Health professionals should select clinical assessments based on a sound knowledge and understanding of the classification of balance and postural control strategies.

Twenty barriers were identified, classified under the headings 'ability', 'opportunity' and 'implementation'. Seventy-nine (92%) of all respondents agreed that keeping up to date with research findings was important to them, but only 7 (8%) were happy with the time that they had to do this. Fifty-eight (67%) perceived a need for further training. Only 4 (5%) agreed that it was easy to transfer research findings into their daily practice. A number of significant differences were found between the perceived barriers of different disciplines.

The regime of independent practice had no measured beneficial effect on the balance ability of patients with recently acquired stroke.

Stroke rehabilitation needs to establish and apply a solid evidence-base even though the challenges are formidable.
