From: The immediate effect of muscle release intervention on muscle activity and shoulder kinematics in patients with frozen shoulder: a cross-sectional, exploratory study

  FS group Mean (SD) Asymptomatic group Mean (SD) P-valuea
Age (years) 52.85 (5.95) 53.15 (7.14) 0.89
Gender (male/female) 8 M/12F 8 M/12F 1.00
BMI (kg/m2) 22.21 (3.43) 23.32 (3.20) 0.30
Affected or tested shoulder (dominant/ non-dominant) 12/8 12/8 1.00

  1. SD: standard deviation
  2. BMI = body mass index (height/weight2)
  3. aBetween group comparisons were assessed using independent t test for continues variables, and chi-square test for the nominal variables. The level of significance was set at p < .05
