Run, Stop, Jump Test (RTP Testing)

Instructions

    A distance of 30ft is marked off for the patient. The patient is instructed to sprint forward a distance of 30ft (10yds) as fast as possible, immediately stop, and then perform a symmetric two-footed takeoff and vertical jump for maximum height. The patient will then perform a two-footed landing after the jump. 

Scoring

    The patient’s sprinting, deceleration, and jumping and landing control will be assessed by the clinician for a PASS/FAIL grade based on the following criteria: 

  • Symmetrical loading and knee flexion during deceleration
  • Feet hit the ground at the same time during landing
  • Symmetric landing after jump
  • Can decelerate without hesitation

Patient must demonstrate 3 of the 4 components to pass the test. 

Tuck Jump Assessment (RTP Testing)

Instructions

    Markers will be placed along a wall at a 90-90 hip flexed position and at the feet when feet are placed shoulder-width apart. The patient will be instructed to perform 10 rapid, consecutive tuck jumps. The tuck jump assessment will be filmed from both a front and lateral view. The tester will identify if any of the 10 technique flaws listed below are observed and will score accordingly.

Possible technique flaws:

  • Lower extremity valgus at landing
  • Foot placement not shoulder width apart
  • Thighs not equal side-to-side (during flight) 
  • Excessive landing contact noise (lateral view)
  • Foot placement not parallel (front to back) (lateral view)
  • Thighs do not reach parallel (peak of jump) (lateral view)
  • Foot contact timing not equal
  • Does not land in same footprint (excessive in-flight motion) 
  • Pause between jumps
  • Technique declines prior to completion of 10 jumps 

Scoring

    The patient will start with a score of 10. Subtract 1 point for each technique flaw observed. Subtract 2 points if patient is unable to complete 10 consecutive jumps. A score of of 5 or more is a passing score. 

Vertical Depth Drop Test (RTP Testing)

Instructions

     The box depth jump will be filmed from an anterior view only. Instruct patient to stand on the 12” box, then, jump off the box, landing on ground directly in front of box, jump up again as high as they can, then finish in double-leg landing. The jumps must be vertical in direction, avoiding forward motion towards the camera.

Scoring:

3 - GOOD: Patient jumps and lands with symmetrical movement; lands with knees, hips, and toes in-line, equal knee separation, controls the landing, and does not demonstrate a loss of knee valgus control.
2 – FAIR: Patient demonstrates slight deviations, but thighs still reach parallel to the floor.
1 – POOR: Patient exhibits asymmetrical mechanics; loss of knee control, poor knee separation, loss of balance, significant knee valgus, poor trunk control, and/or poor knee flexion/absorption.

Single-leg 90° Rotational Medial/Lateral Hop (RTP Testing)

Instructions

   Instruct patient to stand facing parallel to the start line on the uninvolved limb with hands on hips. The patient will hop off of uninvolved limb as far as possible, performing 90° medial or lateral turn to land facing forward, maintaining hands on hips. Patient will be hopping for distance, measured from the heel. Instruct patient to hop first, prior to turning, to avoid twisting at the knee. The single-leg forward leap will be filmed from a frontal view.

Scoring

    Measure the distance closest to start line (from patient’s heel). Perform three repetitions for each leg. All measurements are made in centimeters.

Single-leg Triple Crossover Hop Test (RTP Testing)

Instructions

     Mark a strip on the ground with tape 20 ft long and 15cm wide. Instruct the patient to stand on uninvolved leg with hands on hips, behind the start line.  Instruct the patient they are to hop 3 consecutive times on one foot, crossing over the center strip on each hop. The first hop will be medial across the tape line. The patient is encouraged to hop as far forward as possible on each hop, but must stick the final landing and hold for 2 seconds. Perform three repetitions for each leg. The single-leg forward leap will be filmed from a frontal view. 

Scoring

    Measure the distance closest to start line (from patient’s heel). Perform three repetitions for each leg. All measurements are made in centimeters.

Single-leg Forward Hop/Leap (4-Month and RTP Testing)

Instructions

    Instruct the patient to stand on uninvolved leg with hands on hips, behind the start line. Instruct the patient to hop as far forward as possible, landing on the same leg. The patient must control the landing and hold for 2 seconds. If a forward hop cannot be completed safely, and forward leap can be performed jumping from the uninvolved leg to the involved leg. A single-leg forward leap is named for the starting leg (i.e. if patient hops (R) to (L), it would be a (R) leap). The single-leg forward leap will be filmed from a frontal view.

Scoring

    Measure the distance closest to start line (from patient’s heel). Perform three repetitions for each leg. All measurements are made in centimeters.

Y Balance Test (4-Month and RTP Testing)

Instructions: 

    For this test, you must measure limb length of both the involved and uninvolved side. The patient will lie supine on table. Use tape measure in cm, start at ASIS and measure to medial malleolus of both the involved and the uninvolved limb.
    Instruct the patient to stand on the uninvolved leg with opposite leg lightly touching ground behind for balance. The patient will push the target indicator with toes, maintaining contact the entire time, then will return to starting position without losing balance. The patient must not place foot on top of target indicator to allow shifting weight for balance or kick target indicator. The patient will perform 3 repetitions on the noninvolved, followed by 3 repetitions on involved in the following directions: anterior, posterolateral, posteromedial.

Scoring

    Measure score in 0.5 cm increments and take the average of the 3 trials and report one score for each direction. A composite score is determined by taking the average of the 3 trials and diving it by three times the limb length, multiplied by 100%. A score of 94% is passing.*

Timed 1/3 Squat Test (4-Month and RTP Testing)

Instructions

    The patient starts by standing in front of a surface that allows for approximately 45° of knee flexion before the buttocks contacts the surface (e.g. hi-lo table). Instruct patient to place both hands on hips and remain there for the entire test. Instruct patient to stand with contralateral limb out in front and to squat down until their buttocks taps the surface then returns to starting position. They will perform as many repetitions as possible for 30 seconds for the 4-Month Assessment and 60 seconds for the RTP Assessment. 

Scoring

    Record the repetitions for each leg then divide involved by uninvolved x 100 for percentage score. Only record quality repetitions, patient should focus on proper form before speed.
