“…Our finding that RSCM performance is poorer in stunted children concurs with the findings of other studies that have used tasks from the Neurological Examination of Soft Signs, 7–9 and we controlled more extensively for socioeconomic differences. One study also found differences in performance on Grooved Pegboard tests, 6 but we are unaware of another study with undernourished children using similar pencil and paper tasks.…”

“…There is limited evidence that children’s fine motor ability is affected by undernutrition 6,7 . In a study of Indian school‐aged males, low weight for age was associated with poorer performance on motor tasks; out of the 16 males with the worst scores, 15 had abnormal electroencephalogram patterns, mostly in the frontal lobes 8 . In another study, 10‐year‐old Indian children who were underweight and stunted in early childhood had deficits in timed coordinated tasks and balance, 9 but not in dexterity 10 .…”

PPVT Peabody Picture Vocabulary Test RSCM Rapid sequential continuous movements AIM The aim of this study was to determine the effects of early childhood stunting (height for age 2SD or more below reference values) and interventions on fine motor abilities at 11 to 12 years, and the relationship between fine motor abilities and school achievement and intelligence.METHOD A cohort of stunted children who had participated in a randomized trial of psychosocial stimulation and ⁄ or nutritional supplementation in early childhood was compared with a group of non-stunted children. Fine motor abilities were assessed in 116 stunted (67 males, 49 females) and 80 non-stunted children (43 males, 37 females) at a mean age of 11 years 8 months (SD 4.3mo) and 11 years 9 months (SD 3.8mo) respectively. Testers were blind to the children's group assignment.RESULTS Two fine motor factors were derived: rapid sequential continuous movements (RSCM) and dexterity. No effect of the early intervention was found. RSCM scores were lower in the stunted group than in the non-stunted group (p=0.01), but differences in dexterity were not significant (p=0.18) after adjusting for social background. Among stunted children, the RSCM score was significantly associated with IQ (p=0.04) and school achievement (all p<0.05).

“…The most consistent EEG finding, based on the derived measure of percenttotal power, was that low boron intake resulted in a shift toward more activity in the lower frequencies and less activity in the higher, dominant frequencies of the EEG spectrum. This is a particularly important finding, considering that the same effect is often observed in response to nonspecific malnutrition (20,21) and heavy metal toxicity (12,22,23). Increased low-frequency activity is typical of states of reduced behavioral activation (i.e., drowsiness) and mental alertness (24), and has been associated with poorer performance on vigilance and psychomotor tasks (25,26).…”

Although the trace element boron has yet to be recognized as an essential nutrient for humans, recent data from animal and human studies suggest that boron may be important for mineral metabolism and membrane function. To investigate further the functional role of boron, brain electrophysiology and cognitive performance were assessed in response to dietary manipulation of boron (l0.25 versus =3.25 mg boron/2000 kcal/day) in three studies with healthy older men and women. Within-subject designs were used to assess functional responses in all studies. Spectral analysis of electroencephalographic data showed effects of dietary boron in two of the three studies. When the low boron intake was compared to the high intake, there was a significant (p<0.05) increase in the proportion of low-frequency activity, and a decrease in the proportion of higher-frequency activity, an effect often observed in response to general malnutrition and heavy metal toxicity. Performance (e.g., response time) on various cognitive and psychomotor tasks also showed an effect of dietary boron. When contrasted with the high boron intake, low dietary boron resulted in significantly poorer performance (p<0.05) on tasks emphasizing manual dexterity (studies 11 and 111); eye-hand coordination (study 11); attention (all studies); perception (study 111); encoding and short-term memory (all studies); and long-term memory (study 1). Collectively, the data from these three studies indicate that boron may play a role in human brain function and cognitive performance, and provide additional evidence that boron is an essential nutrient for humans. -Environ Health Perspect 1 02(Suppl 7): 65-72 (1994)

“…The absence of an association with measures of malnutrition contrasts with previous studies (Galler et al . 1984, 1987; Agarwal et al . 1989) and is surprising given the evidence for the vulnerability of the brain to early nutritional insults (Winick et al .…”

Age was the major association of motor incoordination indicating the importance of maturation. Behaviour, vocabulary, visuospatial reasoning, material deprivation, perinatal complications, chronic physical symptoms and occupational status of the father were also independently associated with motor co-ordination. Using sibling pairs, evidence of familial aggregation of motor co-ordination was found.
