En este estudio el objetivo fue evaluar variables antropométricas de la mano: Largo palma, índice de forma, perímetro de muñeca, perímetro a 1 cm distal del perímetro de la muñeca, índice de muñeca y ajustarlas por género, edad, ocupación, tiempo en el oficio, como factores de riesgo independiente para Síndrome de Túnel del Carpo. Se realizó un estudio de casos y controles con 63 casos con diagnóstico electrofisiológico, de los cuales 58 eran mujeres, 5 hombres contra 63 controles asintomáticos, de los cuales 52 mujeres y 11 hombres. La evaluación de las variables se realizó mediante un análisis bivariado y un análisis multivariado (Regresión Logística) a lo cual se le aplicó una prueba de bondad de ajuste (Análisis de varianza ANOVA). La estratificación de cada una de las variables por género, no fue posible realizarla por el número reducido de hombres. El análisis bivariado mostro la edad mayor de 40 años, largo palma menor de 105.5 mm tiene un efecto significativo de riesgo; que el índice de forma, el perímetro de muñeca, el índice de muñeca, el índice de masa corporal, el perímetro a 1 cm distal del perímetro de muñeca fueron significativamente mayores en el grupo de casos que en el grupo control. En el análisis de regresión logística mostró que la edad mayor de 40 años, I.M.C mayor de 24.9 kg/m2, tiempo en el oficio de 5 a 10 años, el largo palma menor de 105.5 mm, tienen un efecto significativo de riesgo para Síndrome de Túnel del Carpo. En la prueba de bondad de ajuste del modelo de regresión logística (Análisis de varianza ANOVA) Las variables que presentan un efecto significativo para riesgo son: Ocupación 1-Trabajo Operativo Manual, Tiempo en el oficio de 5 a 10 años, Edad mayor de 40 años, I.M.C. mayor de 24.9 Kg/m2 y largo palma menor de 105.5 mm. En conclusión, de las medidas antropométricas evaluadas, la única que presentó una asociación significativa con síndrome de túnel del carpo fue el largo palma menor de 105.5 mm. De las variables individuales y relacionadas con la ocupación presentaron un efecto significativo para riesgo, las ocupaciones que implican trabajos operativos manuales, tiempo en el oficio de 5 a 10 años, edad mayor de 40 años, Índice de masa corporal dentro de los rangos de sobrepeso y obesidad.

Objective: to determine the palm-plant paleness’ characteristics in Colombian infant rural population, as a diagnostic method of anemia, and to establish a correlation between the finding of palm-plant paleness and the Hematocrit values. Methodology: a cross sectional study was used to evaluate 169 boys and girls, between 2 months and 12 years old, of the rural area of San Vicente del Caguan, who entered into a Health Campaign. Following the signature of an informed consent, parents accept their children to participate in the study. Those with acute or chronic pathologies were excluded. The presence of palm-plant paleness was determined by observers trained in the Integrated Management of Childhood Illness (IMCI) Strategy. Hematocrit was measured to all children, as well as a peripheral blood smear. Interrater concordance evaluation (Kappa index) was determined through a pilot test and a validation (sensitivity, specificity) was performed, using Hematocrit as the standard. Results: 93 of the participants were male and 77 were female. 45% of them had palm paleness. The Hematocrit showed anemia in 34.1% of the children. The validation analysis demonstrated a 67.2% of sensibility, a 66.6% of specificity, a 51.3% of positive predictive values and a 79.5% of negative predictive values. Hypochromic and Eosinophilia were found in most of the peripheral blood smears’ children with anemia. Conclusions: although this tool presents a low sensibility and specificity for low/moderated anemia, it is useful for excluding it in infants without palm paleness.

The objective of the investigation who gave as result this work was to investigate the effectiveness of kinaesthetic motor imagery in the activation of the hemiplegic hand muscles following stroke. The experiment consisted of two random groups. Movements were measured after treatment. The participants were ten patients with hemiplegic hands (men who mean age was 74.4 years; mean time since stroke 3.05 months). All patients received three sessions of physical treatment based on an identical treatment protocol. Five patients were randomly assigned to an experimental group practising kinaesthetic motor imagery of a grasp using the 'lumbrical action' (experimental group). The others five (control group) followed a relaxation script. All the patients were then asked to grasp an object using the 'lumbrical action'. The grasps were recorded using an optoelectronic motion capture system. The magnitude of the extension of the index finger and the correlation of the angular displacement of the proximal phalangeal joints and the metacarpophalangeal joints were calculated. The movement time for the whole grip was calculated. The experimental group demonstrated higher extension in the index finger (p = < 0.01) and they had a higher correlation coefficient (0.99) than the control group (0.77) for the displacement of the proximal interphalangeal joint and the metacarpophalangeal joints. The movement time for the experimental group was faster, although the difference was not significant.
