Dear Biomch-L readers,

Many of the postings on this list are concerned with analysis of movement by
itself, i.e., the biomechanical and -- sometimes -- underlying neurological
aspects. Often, such analyses are concerned with straight, level, constant
velocity, free/treadmill walking. The following article from, a.o., one of
our subscribers might therefore be of additional interest.

>From the Analysis of Movements to the Analysis of Skills -- Bridging the
Gap between Laboratory and Clinic

Journal of Rehabilitation Sciences (The Netherlands), 4(1991/3)1, 9-12.

SUMMARY -- Clinical assessment of balance and gait is discussed on the
basis of an information processing approach, in which motor behaviour
is seen as the result of a fine-tuned interaction between perceptual,
cognitive and motor processes. From such a proces-oriented viewpoint,
stance and gait are regarded as complex skills that cannot be adequately
assessed when the motor output is taken as an isolated object of study.
It is argued that the assessment of a basic motor act under more complex
environmental conditions will reveal essential information about the motor
behaviour as a skill and, in the case of pathology, may give insight into
essential aspects of the disability.
Several suggestions are made with respect to creating complex task conditions.
As an example, an estimation of the automaticity of balance control by means
of a dual task procedure is discussed. The value of a process-oriented ap-
proach to disability assessment is stressed as well as the need for a skills
laboratory in rehabilitation medicine.

P.S.: Dr Mulder is a collaborator in the CAMARC-project. It is, there-
fore, gratifying to see that his title reminds of a general policy
paper published in the December 1990 issue of the same journal
(and in an ISB Newsletter issue last year), "The CAMARC Project --
an Attempt to Bridging the Gap" ...
