Tennis is not dangerous for the spine during growth: results of a cross-sectional study

Purpose Tennis is widely practiced by adolescents in many countries. Many spinal deformity experts consider this activity, together with other asymmetrical sports, as risk factors for scoliosis development even though scientific data are missing. The aim of the present study was to verify the prevalence of spinal deformities and LBP in adolescent competitive tennis players compared to healthy controls. Methods We designed a cross-sectional study. A convenience sample of 102 adolescent tennis players (52 girls) was compared to 203 scholars (102 girls) of the same age (12 years). We used a questionnaire to collect data on LBP and we measured the ATR to screen for spinal deformities and the plumb line distances for kyphosis (C7 and C7 + L3) and lordosis (L3). Results We found similar spinal deformities in both groups: ATR female: 3.2° ± 1° (tennis) versus 2.8° ± 1° (school), NS; ATR males: 2.8° ± 1° (tennis) versus 2.6° ± 1° (school), p
