90/90 Plyometric Test

In this video Matt Repa, ATC teaches how to perform the 90/90 Plyometric Test as part of our Upper Extremity Return to Play series.

Instructions: The patient performs 2lb plyometric wall dribbles in a seated or standing position with the arm abducted at 90 degrees and externally rotated to 90 degrees for 30 seconds. Monitor for signs of apprehension. 

Scoring:  Pass: Patient is able to compete the 30 seconds without any pain or discomfort.  
                Fail: Patient reports discomfort or cannot complete the test due to fatigue. 

Weighted Scapular Dyskinesia Test

In this video Therapist Kevin Florentino and Athletic Trainer Jared Ventura demonstrate the Weighted Scapular Dyskinesia Test.


  • The patient will be in an upright sitting or standing position
  • Both scapular must be exposed
  • The therapist may use a video recorder for further evaluation at a later time
  • The patient performs 5 bilateral repetitions of shoulder flexion through full ROM
  • Repeat having the patient perform abduction

To determine weight:

  • 3lb weights if patient is < 68.1kg or 150lbs
  • 5lbs weights if patient is > 68.1kg or 150lbs


  • Pass = Patient demonstrates normal scapular movement
  • Fail = Patient demonstrates abnormal scapular movement

Y Balance Test

In this video IBJI Therapists Molli and Tara take us through the Y balance stability test.

Instructions are as follow:

  • Measure patients limb from C7 to tip of longest finger with shoulder at 90 degrees in frontal plain
  • Thumb is aligned behind the red starting line with the hand on the label side of the line
  • Maintaining a push-up position with feet shoulder width apart the person is asked to reach the free hand in the - medial, inferolateral, and superolateral directions in relation to the stance hand
  • All three reaches are performed sequentially without rest 
  • Patient may rest between trials
  • Shoes are not worn during the test
  • Two practice trials on each side are performed prior to testing


  • Maintain balance on one hand
  • Cannot lift or move the balance hand from the platform
  • Cannot touch down with reach hand
  • Return the reach hand to starting position
  • Maintaining contact with target without pushing or shoving target


  • Composite score = Medial + Inferolateral + Superolateral x 100/ 3 x limb length
  • Pass = less than 4cm asymmetry on involved and uninvolved side
  • Fail = More than a 4cm asymmetry on involved and uninvolved side

Standing External Rotation Endurance Test

In this video IBJI Therapist Tessa Walsh takes us through how to perform the Standing External Rotation Endurance Test. 

Instructions for the test are as follow;

  • Patient stands holding an elastic band that is at shoulder level
  • patient perform external rotation at 90 degrees of abduction on uninvolved UE at a distance where they feel they can perform 30 reps
  • Position is marked with tape 
  • Patient performs ER at 90 degrees of abduction with a pace of 60 beats/minute for 30 seconds
  • If unable to meet 30 seconds or falls behind metronome patient rests for 3 minutes and repeats the test at a closer distance
  • Repeat on involved UE

Pass: patient is able to maintain form for > or equal to 30 seconds
Fail: patient is unable to complete 30 seconds or demonstrates significant loss of form

FMS Overhead Squat

In the video below IBJI Therapists Tara and Carol take us through how to assess the deep squat. A couple things to note;

  • Examine from both a front and lateral view
  • Athlete stands with feet slightly wider than shoulder width apart, and toes externally rotated
  • Athlete will grab dowel rod with elbows bent at 90 degrees and then raise bar overhead with arms fully extended.
  • Athlete will squat as deep as possible for three repetitions in a row.

Give the following Instructions: 

  • The athlete's knees should be traveling same direction as toes
  • Body weight should be evenly distributed throughout entire foot
  • Upper torso should be parallel with shins
  • Hips should drop lower than knees at the lowest point
  • Knees and bar should be aligned directly over feet at lowest point


3 = Good

  • Athlete's feet are shoulder width apart, arms overhead
  • Athlete's squat is below knees and trunk is parallel to shins

2 = Fair

  • Heels elevated on airex pad the athlete is able to give a good squat

1 = Poor

  • With heels elevated athlete is still unable to perform a good squat

FMS Protocol for Trunk Stability Push-up

IBJI Therapists Tara and Carol show how to perform the Stability Push-up. When conducting this test give the following instructions;

  • athlete lies prone
  • hands are shoulder width apart
  • for women they are in line with chin, for men they are in line with forehead
  • Tell athlete "raise your toes towards your shin and place them on the ground. Extend your knees off the ground. Maintain a rigid torso. Raise yourself as one unit with no lag in th elow back into a push-up position)


3 = Good 

  • Males perform one rep with thumbs in line with forehead
  • Females perform one rep with thumbs in line with chin

2 = Fair

  • Males perform one rep with thumbs in line with chin
  • Females perform one rep with thumbs in line with clavicle

1 = Poor

  • Males are unable to perform one rep with hands in line with chin
  • Females are unable to perform one rep with thumbs in line with clavicle

0 = Pain with anything

Prone External Rotation Strength Test

In this video IBJI Therapist Christian Chebny teaches us how to do the Prone External Rotation Strength Test. 


  • patient lies prone on the table with uninvolved arm hanging off edge
  • Holding a dumbbell patient performs external rotation at 90 degrees until han drises above the level of the table to be counted as 1 rep
  • patient must keep arm horizontally abducted
  • patient should perform 6-20 reps until failure due to exhaustion
  • test may be stopped and weight switched depending on ease or difficulty
  • Repeat on involved UE

Uninvolved R/L choose one [(.03xreps)] x (weight)] + weight = ___ Pounds
Involved R/L choose one [(.03xreps)] x (weight)] + weight = ___ Pounds
Pass = > or equal to 90% limb symmetry index
Fail = < or equal to 89% limb symmetry index                 

Davies Upper Extremity Stability Test

IBJI Athletic Trainer Matt Repa talks about how to perform the Davies Upper Extremity Stability Test.  Instructions for this test are as follows;

  • 3 foot long tape is placed on the floor
  • Patient gets in push-up position or modified (depending on gender)
  • When told to start the patient will alternatively move their hands from one end of the tape to the other and place it back where originally started as fast as they can for 15seconds
  • The number of completed reps is recorded
  • The test is completed 3 times and an average score is taken

Patient passes if they complete more then the average reps for their respective gender          
68% bodyweight (lbs) x total number of reps/15
Average reps for Males = 21 - Average reps for females = 23
