Table 1 The mean, median, SD, maximum and minimum values for height, weight, BMI and the five postural angles for the total group and by gender (n = 194)

From: The spinal posture of computing adolescents in a real-life setting

  Group (n = 194) Males (n = 116) Females (n = 78)
  Mean (SD) Maximum Minimum Median Mean (SD) Mean (SD)
Age 16.3 (0.5) 17.0 15.0 16.0 16.3 (0.5) 16.3 (0.5)
Height (m) 1.66 (0.1) 1.96 1.46 1.67 1.70 (0.1) 1.61 (0.1)
Weight (kg) 59.35 (13.1) 111.60 35.10 57.25 60.63 (13.0) 57.44 (13.1)
BMI 21.34 (3.9) 34.15 14.74 20.40 20.77 (3.5) 22.19 (4.3)
Head flexion (°)* 78.70 (8.4) 97.49 53.62 79,22 78.70 (8.5) 78.72 (8.2)
Neck flexion (°) 61.55 (8.7) 92.64 31.87 61,14 61.71 (8.2) 62.26 (9.4)
Cranio-cervical angle (°) 161.62 (7.7) 178.81 141.67 161,27 161.72 (8.2) 161.44 (7.0)
Trunk flexion (°) -9.53 (9.6) 18.84 -37.54 -9,06 -9.89 (9.7) -9.02 (9.6)
Head lateral bend (°)§ -0.67 (5.1) 12.67 -15.26 -1,06 -0.61 (4.8) -0.70 (5.4)
  1. *Head flexion angles greater than 90° were obtained when the canthus was lower than the tragus.
  2. Neck flexion greater than 90° indicated that the tragus was lower than the level of the C7 SP.
  3. If trunk flexion was positive, the C7 SP was positioned anterior to the greater trochanters, and the student had adopted a more flexed posture. If trunk flexion was negative, the C7 SP was positioned posterior to the greater trochanters, and the student had adopted a more extended posture.
  4. §A negative value for head lateral bend indicated that the head was bent in the frontal plane to the left.
