Phase IV: Return to Sport

The Illinois Bone & Joint Institute’s Phase IV Program is designed for patients with hip, knee, or ankle injuries who wish to continue advanced rehabilitation to facilitate return to sport and reduce the risk of re-injury. Our evidence-based protocols will teach and cover multiple aspects of lower extremity conditioning including: 

  • Sport-specific strengthening 
  • Power production 
  • Explosiveness 
  • Plyometric and jump training 
  • Cutting and pivoting mechanics 
  • Techniques for reducing risk of re-injury 
  • Baseline and post-testing to ensure safe return to sport

Ideal candidates for this program include: 

  • Competitive and recreational athletes 
  • High school and collegiate post-injury ACL athletes 
  • Industrial athletes 
  • Weekend warriors 

Phase IV Therapy 

If sport-specific rehab is covered by the patient’s insurance company, the patient will be seen in Phase IV Therapy, receiving one-on-one care with a physical therapist and/or athletic trainer. Phase IV Therapy can be performed at any of our IBJI clinics.

The patient’s individual insurance information will be collected and verified at the time of scheduling to determine coverage for Phase IV Therapy. The Illinois Bone & Joint Institute offers alternative options for patients that may have insurance limitations. 

Phase IV Class

The Phase IV Class is a group training option for patients that may have insurance limitations. In IBJI’s Phase IV Class the patient is educated on jumping, landing, sprinting, deceleration, and cutting mechanics and is progressed through an advanced strengthening program in a small group setting. As a group, patients will progress together through the Phase IV program which gives the opportunity to develop relationships with others with similar injuries. 

The Phase IV Class is a 6-week intensive training program, with classes twice a week. All sessions have a 7th week available for make-up classes. Attendance twice a week is mandatory and baseline testing must be completed prior to the start of class. The cost of the class is $30/session, for a total cost of $360, and is not covered by insurance.

For continuity within each Phase IV Class, we strongly request that all participants start on the listed start date for a given location. While the Phase IV Class is meant for patients that have insurance limitations, participation in Phase IV Class may be based on patient or doctor preference.

Phase IV Testing

During the course of a patient’s recovery, incremental testing will be conducted to assess the patient’s strength and readiness to progress to various activity benchmarks and/or the next phase of rehabilitation. The patient’s involved knee will be compared to the uninvolved side in order to individualize each assessment. The Illinois Bone & Joint Institute offers a variety of testing in order to ensure a safe and full recovery.

Phase IV Baseline Assessment: In order to ensure the patient has the proper strength to enter the Phase IV Program and/or start the Phase IV Class, there are a few criteria the patient will have to successfully meet in our Phase IV Baseline Assessment. This assessment will evaluate functional strength and limb symmetry and may include Biodex Testing and/or Proprio 5000 Testing, per the physician’s instructions/protocol. 

Phase IV Return-to-Sport Assessment: The Illinois Bone & Joint Institute offers a standard Phase IV Return-to-Sport Assessment comprised of an evaluation of functional strength, limb symmetry, plyometric power, and visual assessment of dynamic movement. This assessment provides the physician, physical therapist, and/or athletic trainer with valuable information to assess the patient’s readiness to safely return to sport. The Phase IV Return-To-Sport Assessment is to be completed ONLY when deemed appropriate by the physician, physical therapist, and/or athletic trainer. The standard Phase IV Return-to-Sport Assessment can be performed at any Illinois Bone & Joint Institute rehabilitation clinic. Biodex Testing and/or Proprio 5000 Testing may be recommended, per the physician’s instructions/protocol.

Biodex Testing: The Biodex is used to precisely measure the force generated by the prime muscles that move the knee: the quadriceps and hamstrings. The strength of these muscles are tested at different speeds in order to give the physician, physical therapist, and/or athletic trainer insight into the patient’s individual progress and any remaining deficits and/or imbalances. Biodex testing is offered at our Highland Park, Palatine, and Chicago – Avondale physical therapy clinics. Biodex testing can be added as an adjunct test to the standard Phase IV Assessments to provide additional information to the physician, physical therapist, and/or athletic trainer and will be recommended if desired by the physician. 

Proprio 5000 Testing: The Proprio 5000 is used to measure, assess, and train the patient’s dynamic stability. The athlete stands on a moving platform with either double-leg or single-leg stance, attempting to maintain his or her balance with good core, hip, and knee control. This testing provides the physician, physical therapist, and/or athletic trainer insight on the patient’s lower extremity strength and dynamic core, hip, and knee stability. Proprio 5000 testing is offered at our Glenview and Morton Grove physical therapy clinics. Proprio 5000 testing can be added as an adjunct test to the standard Phase IV Assessments to provide additional information to the physician, physical therapist, and/or athletic trainer and will be recommended if desired by the physician.

Return To Sport

IBJI’s Phase IV Program is designed to offer a comprehensive approach to returning the patient to the court/field. In order to ensure a full and safe return to sport and minimize the risk of future injury, test selection and return-to-sport criteria are set based on evidence-based research. The criteria require strength, functional movement, and dynamic movement scores on the involved limb to be within 85-90% of the uninvolved limb to ensure normalized endurance, strength, stability, and power. The physician, physical therapist, and athletic trainer will work together with the patient to determine when he/she may officially return to sports participation.
