Figure 2From: Biomechanical analysis of rollator walkingAverage joint angular curves (degrees) of the ankle, knee and hip in the sagittal plane and of the hip in the frontal plane. Dotted lines reflect walking with a rollator (n = 7) and solid lines reflect normal walking (n = 7). Positive values indicate hip abduction/extension, knee extension and ankle plantarflexion. 0 % on the x-axis is heel strike and 100 % is toe-off.Back to article page
