Intra-rater Reliability of clinical tests.

Test	Authors	INTRA-RATER Reliability	Percentage Agreement/Description
Crook lying hip abduction/lateral rotation	Luomajoki et al. [33]	K = 0.86	O1/O2 = 97.5
Dynamic lunge test (DL)	Granström et al. [32]	ICC = 0,54–0,82	The trunk moves forwards (TMF) and falls over the front of the leg.
		K = 0.47–0.79 for Trunk Lateral Flexion
		K = 0.63–0.74 for Knee moving inwards
		K = 0.68-0.89 for Pelvic Tilt
		K = 0.47–0.90 for Hips moving backwards	The shoulders move backwards (SMB) when returning back to the start position.
		K = 0.64–0.95 for trunk moving forwards
		K = 0.79–0.95 for shoulders moving backwards
Knee lift abdominal test (KLAT)	Ohe et al. [38]	ICC=0.71–0.79
One leg stance/Trendelenburg	Luomajoki et al. [33]	K = R:0.67 L: 0.84	O1 = R: 92.5
			L: 87.5
			O2 = R/L:100
Pelvic tilt	Luomajoki et al. [33]	K = 0.80	O1/O2 = 95.0
Prone active knee flexion/prone knee bending	Luomajoki et al. [33]	K(Ext) = 0.70	O1 = (Ext/Rot) 92.5
		K(Rot) = 0.78	O2 = (Ext) 92.5—(Rot) 100
Rocking backwards	Luomajoki et al. [33]	K = 0.72	O1/O2 = 97.5
Rocking forwards	Luomajoki et al. [33]	K = 0.51	O1 = 95.0
			O2 = 100
Sitting knee extension	Luomajoki et al. [33]	K = 0.95	O1/O2 = 100
Standing back extension test	Gondhalekar et al. [31]	K = 0.87	96
Standing knee-lift test (SKL)	Granström et al. [32]	ICC= 0.57–0.75	Hip hitch (HH): Instead of lifting the thigh up in the sagittal plane, the pelvis tilts in the frontal plane.
		K = 0.42–0.79 for hip hitch
		K = 0.63–0.95 for lateral sway	Lateral sway (LS) of the pelvis on the stance leg.
		K = 0.79-0.89 for trunk lateral flexion	Trunk lateral flexion (TLF) to either side.
		K = 0.42–0.84 for knee not lifted straight up	Knee is not lifted straight up (KNLSU).
		K = 0.76–1.00 for arm lowering	One arm is lower (AL) on one side.
		K = 0.89–1.00 for back extension	The back extends (BE) during the movement.
		K = 0.61–1.00 for back flexion	The back flexes (BF) during the movement.
Static lunge test (SL)	Granström et al. [32]	ICC = 0.54-0.87
		K = 0.42–0.89 for trunk lateral flexion
		K = 0.95–1.00 for arm lowering
		K = 0.63–0.74 for knee moving inwards	The front knee moves inwards (KMI) and not aligned with the hip and foot.
		K = 0.63–0.95 for pelvic tilt	The pelvis tilts (PT) to either side and not horizontally aligned.
		K = 0.53–0.89 for hips backwards
			The hips move backwards (HMB) instead of downwards. The back seems to arch.
Waiter’s bow/trunk flexion	Luomajoki et al. [33]	K = 0.88	O1 = 97.5
			O2 = 100

NB: Tests are described in the table “Inter-examiner reliability”. Legend: O = Observation, R = Right, L = Left, Ext = Extension, Rot = Rotation.
