Table 3 Current and past physical activity for the AIS braced (AIS-B), AIS not-braced (AIS) and control (CON) groups

From: Does bracing affect bone health in women with adolescent idiopathic scoliosis?

   AIS-B(n = 15) AIS(n = 15) CON(n = 19) ANOVA (p-value)
Current physical activity (times/wk) Mild 2.6 ± 1.7 3.2 ± 2.6 4.6 ± 3.6 .10
  Moderate 2.1 ± 2.0 3.0 ± 2.1 3.3 ± 2.5 .29
Strenuous 2.0 ± 1.9 1.9 ± 1.9 2.9 ± 1.8 .23
Past physical activity (hrs/wk) Intensity 1 0.1 ± 0.3 0.6 ± 1.5 0.1 ± 0.1 .18
  Intensity 2 1.1 ± 1.7 1.2 ± 3.1 1.0 ± 1.5 .96
Intensity 3 1.5 ± 1.6 3.3 ± 2.7 2.9 ± 4.8 .33
Intensity 4 3.8 ± 5.2 6.0 ± 5.9 5.3 ± 5.8 .57
  1. Values are presented as means ± SD; there were no significant differences between groups (p > .05).
  2. Mild = minimal effort (e.g., easy walking), moderate = not exhausting (e.g.,. fast walking), strenuous = heart beats rapidly (e.g.,. running, soccer, squash, basketball),
  3. Intensity defined as:
  4. 1 = activities that require only sitting with minimal walking.
  5. 2 = activities that require a minimal amount of physical effort such as standing and slow walking with no increase in heart rate and no perspiration.
  6. 3 = activities that require carrying light loads (5–10 lb or 2–5 kg), continuous walking, mainly indoor activity and that would increase the heart rate slightly and cause light perspiration.
  7. 4 = activities that require carrying heavy loads (>10 lb or >5 kg), brisk walking, climbing, mainly outdoor activity, that increase the heart rate substantially and cause heavy sweating.
