Table 1 Characteristics of the 16 participants with ACL rupture

From: Altered movement patterns and muscular activity during single and double leg squats in individuals with anterior cruciate ligament injury

Body Mass Index (BMI; kg/m2), mean (SD) 24.6 (5.1)
Dominant side: right 14
Injured side: dominant 6
Participants with Magnetic Resonance Imaging-verified associated meniscal afflictions 5
collateral ligament injury 5
compressive trauma/bone bruise 13
KOOS sport/recreation, mean (SD) 38.1 (32.3)
KOOS quality of life, mean (SD) 44.7 (21.1)
IKDC, mean (SD) 58.2 (16.3)
Tegner activity scale before injury, median (min – max) 6 (3 – 10)
Tegner activity scale at the testing occasion, median (min – max) 3 (1 – 6)
TSP Total score non-injured side, median (min – max) 0 (0 – 5)
TSP Total score injured side, median (min – max) 9.5 (2 – 20)
p-value p ≤ 0.000
median difference, 95% CI 6.5 (5 – 12)
  1. KOOS = Knee Injury and Osteoarthritis Outcome Score. The 2 subscales sport/recreation and quality of life (range from 0 “extreme problems” to 100 “no problems”) were used in this study.
  2. IKDC = the International Knee Documentation Committee Subjective Knee Evaluation Form (ranging from 0 “absence of symptoms” to 100 “no limitations of daily living”).
  3. Tegner activity scale (ranging from 1 “low activity like walking on even ground” to 10 “high activity like American football”).
  4. TSP = Test for Substitution Patterns (comprising 5 test-movements; total score ranging from 0 “no substitution pattern” to 54 “very clearly present, subject performed very poorly” where altered movements (substitution patterns) were scored as observable, predefined deviations of postural orientation).
  5. SD = Standard Deviation.
  6. 95% CI = 95% Confidence Interval.
