The development of restrictive physical interventions (RPI) to manage challenging behaviours based upon control and restraint during the 1980s and 1990s led to widespread professional disquiet and campaigning to improve the policies, training and application of physical techniques. This included the promotion of a value base within which physical techniques should be used. This value base may be summarised as any use of physical interventions must be in the person's best interests, "least restrictive" and used as the last resort following preventive strategies. The last resort principle "implies" that services should be able to demonstrate support plans to prevent or reduce the frequency and/or restrictiveness of PI used in individual cases. This paper proposes that adopting explicit policies and practice to reduce restrictive PI is likely to be more effective in improving quality of support as opposed to solely managing PI use. Discussion of current policy and practice is followed by discussion of organisations' roles in relation to RPI reduction, with international comparisons.
