Functional Progressions & Functional Testing in Rehabilitation Chapter 16 How do you move forward in Rehab? • Function in rehab = patterns of motion that use multiple joints acting with various axes & in multiple planes – Essential part of rehab that places tissues under stresses that return tissues to levels of full activity – Places stresses & forces on each body system • Traditional rehab techniques often stress only single joints in single planes of motion • To complement traditional rehab, you can use functional rehab to ready your patient for activity Functional Progression • Functional progression = succession of activities that simulate actual motor & sport skills – Enables the patient to acquire or reacquire the skills needed to perform activity – Must be able to adapt rehab to the sport-specific demands & specific position • The clinician breaks down the activities into individual components. – The patient can focus on each specific part of an activity. Benefits for Using Functional Progression • Helps patient reach goals of entire program • Goals of functional progression: – – – – – Restoration of joint ROM Restoration of strength Restoration of proprioception Restoration of agility Restoration of confidence • Provides both physiological & psychological benefits to the patient Benefits for Using Functional Progression • • • • • • Improves functional stability Muscular strength – SAID principle Endurance – muscular & cardiorespiratory Flexibility – elongating tissue to proper length Muscle relaxation – reduce muscle tension Motor skills – coordination & agility, automatic reactions Psychological & Social Considerations • Anxiety – uncertain about future • Deprivation – losing contact with team & coaches • Apprehension – precursor to re-injury • Success of activity gives confidence & motivates to attain the next goal Components of a Functional Progression • Phase 1 – Acute Injury Phase – Focus on restoring joint ROM, muscular strength, & muscular endurance • Phase 2 – Repair Phase – Focus on incorporating proprioception & agility exercises • Phase 3 – Remodeling Phase – Focus on restoring everything to pre-injury status • Progression should allow for planned sequential activities that challenge the athlete while allowing for success Activity Considerations • Principles for activity selection – Individuality of athlete, sport and injury – Should be positive (no increase in symptoms should occur) – Orderly progressive program should be utilized – Variety – avoid monotony, but don’t cause confusion • • • • • Vary exercise techniques used Alter the program at regular intervals Maintain fitness base to avoid re-injury with return to play Set achievable goals, reevaluate, & modify regularly Use clinical, home, & on-field programs to vary activity Activity Considerations • Make sure the patient understands the rehab process • You need to emphasize the importance of sport-specific activities to enhance the patient’s return – Incorporate the inherent demands of the sport • Physical & athletic fitness should be merged to maximize athlete response & return to previous levels Designing a Functional Progression • • • • No cookbook method You are only limited by creativity Should be initiated early in progression Guidelines – Evaluate the patient’s current status – Review expectations of the patient and physician • Do they work together? – Understand demands of sport and position played • May require incorporation of athlete, coach and other athletic trainers – Analyze demands that will be placed on athlete (rank order) – Set goals and means to assess levels of function and progress – Set parameters for return to play criteria Components of Physical Fitness & Athletic Fitness Full Return to Play • Decision requires full evaluation of athlete’s condition – Objective observation and subjective evaluation • Athlete should feel ready physically and mentally • Controlled return – Added stress to injury can slow healing and result long and painful recovery or re-injury • Criteria – – – – Physician’s release Pain free, no swelling Normal ROM, strength Completion of functional testing minus adverse effects Functional Testing • Patient performs certain tasks appropriate to the stage in the rehab process in order to isolate and address specific deficits • Purpose for functional testing • • • • Determines risk of injury due to limb asymmetry Provides objective measures of progress Measures ability of individual to tolerate forces Used as an indirect measure of strength and power • Functional tests serve as good correlation to functional ability • Utilize valid and reliable tests • Should look at both unilateral & bilateral function – Allows clinician to determine if athlete is compensating • Must consider stage of healing, appropriate rest & selfevaluation Functional Testing • Limitations of functional testing – Might be limited due to lack of availability of normative values or pre-injury baseline values for comparison subjective decisions must be made based on test results • E.g.: BESS – If normative data/pre-injury status is available objective decisions can be made • Functional test should be easily understood by athletic trainer & patient • Must consider cost efficiency, time and space demands Examples of Functional Progression & Testing The Upper Extremity • Possible functional activities that can enhance upper extremity performance – PNF, swimming, pulley machines, rubber tubing – All can be used to simulate sports activity • Must focus on proprioception & neuromuscular control – – – – Awareness of proprioception Dynamic stabilization restoration Preparatory and reactive muscle facilitation Replication of functional activities • Kinesthesia training can use similar activities – Requires removal of external cues • Promotion of joint position sense – Activities that can be used • • • • Isokinetic exercise Proprioception testing devices Goniometry Electromagnetic motion analysis – Can be practiced with visual cue progressing to no cues – Activities can be active or passive – Can also work to reproduce specific paths of motion to increase functional component of activity – Must stress joint at both ends of ROM and at mid-range • Results in capsuloligamentous afferents & musculotendinous mechanoreceptors, respectively • Dynamic stability – Stresses the training of force couples provided by scapula stabilizers & muscles of the glenohumeral joint – CKC exercises enhance co-activation • Preparation and Reaction – Incorporates rhythmic stabilization activities along with CKC exercises • Rhythmic stabilization prepares athlete for motion and improves muscle stiffness while training for reaction – Plyometrics are an excellent alternative activity • Functional Activities – Stress sports specific skills – PNF patterns can be used as early alternative to sports specific activity (more function, less stress) • Program should focus on core, scapulothoracic stabilizers and the glenohumeral joint – Quadruped position allows athlete to work muscles of trunk/core and upper extremity • While most activities are OKC oriented, CKC activities are important for restoration of proper function • Throwing Progression – Instruct athlete in complete an appropriate warm-up • Should incorporate throwing motion practice (slow velocity with low stress) – Progress through increasingly difficult stages • Shoulder serves as template for upper extremity rehabilitation and progression – Many of the activities for the shoulder are equally effective for the elbow, wrist and hand Functional Testing for the Upper Extremity • Timed performance is simplest & most common means used for testing • Velocity • • • • Controlled environment (indoors to decrease effect of weather) Set up a standard pitching distance (60’6”) Have athlete use a wind-up motion Measure a maximum of 5 throws measured in mph with radar gun (if no radar gun – use stop watch) • Compute the mean and compare to pretest values • CKC Upper Extremity Stability Test • Use sports specific drill to assess performance & readiness Progression for the Lower Extremity • Utilizes same basic pattern as upper extremity • Can use sprint times, agility runs for time, hopping (height and distance), co-contraction tests, carioca runs and shuttle runs • Sprint test – Set distance – Run the distance for time – 3-5 sprints should be completed and the mean computed – Pre-test and post-test measures are compared • Agility test – Same premise as sprint test – Difference involves the course • Not just straight ahead running • Incorporates changes in direction, acceleration, deceleration, starts & stops – Other agility tests • • • • • Box runs Zigzag runs Cutting maneuvers Figure 8 runs Back pedaling drills – Changes in shape and size can make drills more difficult • Vertical Jump – Record height athlete is able to jumps (3-5 trials) – Test can also be varied • • • • Bilateral jump vs. Single leg jump Countermovement vs. static squat start Approach step vs. stationary start Upper extremity use for propulsion vs. restricted use • Co-Contraction Semicircular Test – Athlete moves about a semicircular pattern while tethered to taut Theraband using a forward facing shuffle – Athlete will complete 3 trials of 5 repetition for time – Provides a dynamics pivot shift for the ACL insufficient knee • Hopping Test – Single leg hop for distance – Timed hop test (ability to hop 6 meters for time) – Triple hop for distance (distance covered in 3 consecutive hops – Crossover hop (distance covered in 3 hops) • Carioca Test – Run performed for time – Run a total of 80 feet, 40 feet to the right and 40 feet to the left, both facing the same direction – Record 3 trials and calculate a mean • Shuttle Run – Four 20 feet sprints (with 3 direction changes) – Suicide sprints – sprint, touch mark and return to starting position (total time to complete drill) • Balance Test – Helps determine deficits in proprioception and balance – Single leg stance (hold position for time) • Can incorporate different surfaces, and eye condition • May also incorporate sports skills into test • Functional Hop Test • Subjective Evaluations – Incorporation of subjective questionnaires or numeric scales to assess function
