Explanation of Terms 

  • Active balance - ability to maintain correct posture while moving (i.e. hopping, jumping, walking) 

  • Bilateral co-ordination – co-ordination between the left and right sides of the body. 

  • Cognitive – includes the processes of knowing and understanding, awareness, judgment and decision-making. 

  • Diadokokinesia  - difficulties with alternating movements. 

  • Low muscle tone – the lack of supportive muscle tone usually with increased mobility at the joints.  The person with low tone seems `loose and floppy` 

  • Motor – pertaining to body movement or posture. 

  • Motor planning – the ability to conceive of, organise, sequence and carry out a complex body movement in a coordinated manner.  Especially if unfamiliar.  

  • Muscle tone – the degree of tension normally presented when one’s muscles are relaxed or in a resting state. 

  • Postural control – automatic movements in the trunk and limbs allowing a person to use only the muscles necessary for a particular motion. 

  • Static balance – ability to maintain correct posture whilst still (i.e. one leg standing) 

  • Visual figure ground – the ability to identify an item from a confused or busy background. 

  • Visual form constancy – the ability to identify a form, even though it may be presented differently, e.g. reversed, larger, smaller or a different colour. 

  • Visual motor – referring to correct physical movement in response to the perception of visual information. 

  • Visual perception – the capacity to interpret or give meaning to what is seen. 

  • Visual discrimination – the ability to match or determine exact characteristics of two forms when one of the forms is among similar forms. 

  • Visual memory – the ability to remember for immediate recall (after four or five seconds) all of the characteristics of a given form, and being able to find this form from an array of similar forms. 

  • Visual-spatial relationships – the ability to determine, from among five forms of identical configuration, the one single form or part of a single form that is going in a different direction from the other forms. 

  • Visual sequential memory – the ability to remember for immediate recall (after four or five seconds) a series of forms from among four separate series of forms 

  • Body scheme – the mental picture of ones own body parts, where they are, how they interrelate and how they move. 

  • Fine motor – referring to movement of the small muscles in the fingers, toes, eyes and tongue. 

  • Gross motor – referring to the movement of the large muscles in the arms, legs and trunk. 

  • Kinaesthesia – the conscious awareness of joint position and body movement in space, such as knowing where to place ones feet when climbing stairs without visual cues. 

  • Motor Praxis – the ability to interact successfully with the physical environment: to plan, organise and carry out a sequence of unfamiliar actions. 

  • Proprioception – the unconscious awareness of sensation coming from ones joints, muscle, tendons and ligaments:  the ‘position sense’. 

  • Sensory – the streams of electrical impulses flowing from the sense receptors in the body to the spinal cord and brain. 

  • Sensory integration – the normal neurological process of taking in information from one’s body and environment through the senses.  This information is then organised and unified and used to plan and execute adaptive responses to different challenges. 

  • Sensory modulation – the brains regulation of the incoming sensory information. 

  • Sensori-motor – pertaining to the brain-behaviour process of taking in sensory messages and reacting with a physical response. 

  • Somatosensory – referring to tactile-proprioceptive perception of touch sensations and body position:’ body sensing’.

  • Occular Motor Control. This is the smooth and coordinated movement of the eyes to attend to follow objects and people in the environment.  Controlled eye movements are needed for finding and tracking a moving object, scanning the environment, quickly shifting focus from one thing to another and for eye-hand coordination.
