Dr Monique de Milander, Lecturer in Exercise and Sport Sciences at the UFS, is leading research on attention-deficit hyperactivity disorder (ADHD) and visual and motor control difficulties.

Research done by the University of the Free State (UFS) has shown that Grade 1 learners not only experience visual problems, but also developmental coordination disorder. Teachers and parents can help to identify this.

In the first study published in the South African Journal of Child Health (https://doi.org/10.7196/SAJCH.2021.v15i1.1705), Dr Monique de Milander, Lecturer in Exercise and Sport Sciences at the UFS, led research on attention-deficit hyperactivity disorder (ADHD) and visual and motor control difficulties.

“Visual problems are often overlooked and are seen as a hidden disability. Thus, children are labelled as ADD/ADHD, but in fact, they have learning-related visual problems. Our eyes connect the world with the brain, and we receive 80-90% of information from our eyes. Consequently, visual problems lead to poor vision, and these visual problems will interfere with children’s ability to learn in the classroom,” she explains.

During the study, ADHD symptoms were found to be significantly associated with half of the visual functioning difficulties. These skills include fixation – the ability to fixate on a stationary object with both eyes – in addition to fixating with the eyes independently.

Ocular alignment of the right eye was indicated as a problem – the ability of the two eyes to work together in order to view an object clearly. Therefore, the eyes must move in a coordinated manner. Visual tracking was the skill that the children struggled with the most in both screening tests; thus, to follow a moving object. This was found for both eyes – the right eye on an X shape, and the left eye on a circle.

She added that science suggests that although children at the age of five or six can perform a variety of manipulative skills such as catching, throwing, kicking, and hitting, the manipulative skills that require visual tracking or the ability to intercept moving objects, develop somewhat later (eight years) due to the sophisticated visual-motor requirements.

Furthermore, although maturation plays a role in achieving these skills, children need opportunities to practise the skills in a variety of settings. Parents and teachers should encourage children to take part in physical activities and sports, in addition to proper instruction on how to perform the manipulative skills.

How will these visual difficulties be identified?

It is important to note that children can fixate, visually pursue objects, and reach accurate decisions about the size and shape of an object; however, some refining still has to take place. In other words, the perceptual abilities of the young child are not yet complete. Some examples of visual perception problems in a young child, as indicated by perceptual motor skills involving the eyes, are as follows:

1. Using control to intercept a ball
2. Interchanging letters and numbers
3. Poor perception of moving objects
4. Poor figure-ground perceptual abilities
5. Distance perception
6. Anticipating timing

What is the next step after identifying visual difficulties?

The first aspect to take into consideration is the age of the child, since we now know that their perceptual abilities need to be refined. If the problem continues, screening tests can be done. If the child is at risk, it is recommended that the parent see an optometrist who specialises in visual problems.

How does one assist a child with ADHD in the classroom?

Five tips for teaching students with ADHD:
1. Change activities frequently to accommodate short attention span
2. Use a positive behaviour modification programme to keep student focused on task
3. Incorporate 3-5 min of conscious relaxation at the end of the physical education period
4. Give brief instructions
5. Use activities that promote cooperation among all students

In another study led by Dr De Milander and published in the South African Journal of Childhood Education (https://sajce.co.za/index.php/sajce/article/view/930), the early identification of learners with developmental coordination disorder was researched.

In children experiencing poor motor skills (fine and gross motor coordination difficulties), without evidence of a neurological disorder and which cannot be linked to a general medical difficulty such as cerebral palsy or a pervasive development disorder, the low motor skills are significant – to such an extent that it interferes with their social competence, academic performance, and physical development, leading to problems with completing daily activities, Dr De Milander explains.

The characteristics of developmental coordination disorder are:

• Experiencing problems getting dressed and tying shoelaces
• Finding it difficult to run, skip, or jump
• Experiencing problems with visual perception
• Poor pencil grip
• Slow and hesitant movement
• Poor spatial concepts about in front, behind, next to, below, and above
• Unable to catch or kick a ball
• Finding it difficult to work in group context

She gives the following advice: Children should be motivated and challenged to participate in simple, yet enjoyable and relaxing physical activities. The focus should be on the child's strengths and not his/her weaknesses. Allow the child to play regularly in sandboxes and with clay. Improve the child’s ball skills by catching and throwing. Motor skills must be learnt through simple mastery steps. Improve the child's movement skills and make participation in movement activities enjoyable and challenging. Concentrate on reaction skills and play in which the child can participate. In extreme cases, specialised treatment by an occupational therapist and a kinderkineticist is important.

It is important to know that children do not outgrow these disorders as previously believed; therefore, many children still experience these difficulties as adolescents. Thus, if your child is experiencing any problems, take cognisance of the problem and address it as soon as possible. Professionals such as kinderkineticists are available in private practice and at various schools to assist your child in improving a variety of deviations. The kinderkineticist can evaluate your child through a standardised test to determine the problem, and then suggest an intervention to address the specific problem, as well as to prevent secondary problems such as low self-esteem, physical inactivity, overweight and obesity, etc., which are associated with these disorders.

For help, visit the website of the South African Professional Institute for Kinderkinetics where you will be able to find a kinderkineticist in your area.

Kinderkinetics is a profession aimed at promoting and optimising the neuromotor development of young children (0-13 years) through science-based physical activity.  All programmes within this profession have a preventative, stimulating, developing, and rehabilitative nature. In summary, it has the following goals:

• Promoting functional growth and proper motor development in young children.
• Focusing on certain movement activities to promote/facilitate sport-specific skills.
• Implementing appropriate rehabilitation programmes for children with growth and/or developmental disabilities in order to maintain an active, healthy lifestyle.

Research into veld fires in grassland can now help with scientifically-grounded evidence
2015-04-10

While cattle and game farmers are rejoicing in the recent rains which large areas of the country received in the past growing season, an expert from the University of the Free State’s Department of Animal, Wildlife, and Grassland Sciences, says that much of the highly inflammable material now available could lead to large-scale veld fires this coming winter.

Prof Hennie Snyman, professor and  researcher in the Department of Animal, Wildlife, and Grassland Sciences, warns that cattle and game farmers should be aware, in good time, of this problem which is about to rear its head. He proposes that farmers must burn firebreaks as a precaution.

At present, Prof Snyman focuses his research on the impact of fire and burning on the functioning of the grassland ecosystem, especially in the drier grassland regions.

He says the impact of fire on the functioning of ecosystems in the ‘sour’ grassland areas of Southern Africa (which includes Kwazulu-Natal, Limpopo, Mpumalanga, the Eastern Cape, and the Harrismith environs) is already well established, but less information  is available for ‘sweet’ semi-arid grassland areas. According to Prof Snyman, there is no reason to burn grassland in this semi-arid area. Grazing by animals can be effectively used because of the high quality material without having to burn it off. In the sourer pasturage, fire may well form part of the functioning of the grassland ecosystem in view of the fact that a quality problem might develop after which the grass must rejuvenate by letting it burn.

Prof Snyman, who has already been busy with the research for ten years, says quantified data on the impact of fire on the soil and plants were not available previously for the semi-arid grassland areas. Fires start frequently because of lightning, carelessness, freak accidents, or damaged power lines, and farmers must be recompensed for this damage.

The shortage of proper research on the impact of fires on soil and plants has led to burnt areas not being withdrawn from grazing for long enough. The lack of information has also led to farmers, who have lost grazing to fires, not being compensated fairly or even being over-compensated.

“When above-and below-ground plant production, together with efficient water usage, is taken into account, burnt grassland requires at least two full growing seasons to recover completely.”       

Prof Snyman says farmers frequently make the mistake of allowing animals to graze on burnt grassland as soon as it begins to sprout, causing considerable damage to the plants.

“Plant roots are more sensitive to fire than the above-ground plant material. This is the reason why seasonal above-ground production losses from fire in the first growing season after the fire can amount to half of the unburnt veld. The ecosystem must first recover completely in order to be productive and sustainable again for the long term. The faster burnt veld is grazed again, the longer the ecosystem takes to recover completely, lengthening the problem with fodder shortages further.  

Prof Snyman feels that fire as a management tool in semi-arid grassland is questionable if there is no specific purpose for it, as it can increase ecological and financial risk management in the short term.

Prof Snyman says more research is needed to quantify the impact of runaway fires on both grassland plant productivity and soil properties in terms of different seasonal climatic variations.

“The current information may already serve as valuable guidelines regarding claims arising from unforeseen fires, which often amount to thousands of rand, and are sometimes based on unscientific evidence.”

Prof Snyman’s research findings have been used successfully as guidelines for compensation aspects in several court cases.
