Spring ICP Exam 1 Flashcards
Prospective study on Eccentric Hamstring Strength and BFIh Fascicle length demonstrated that athletes with a shorter BFIH, were how much times more likely to sustain a HSI than those with longer fascicle lengths?
4.1 times
Athletes with lower eccentric hamstring strength were at how much greater risk of a HSI than stronger players?
4.4 times
What is the progression for eccentric knee flexor exercises?
Bilateral Slider -> Unilateral Slider/Nordic Hamstring -> Unilateral Slider + Load/Nordic Hamstring + Load
What is the progression for long hip extensor exercises?
Asking Diver/Bilateral 45 degrees hip extension -> Asking Diver + Load/Unilateral 45 degrees hip extension/Bilateral hamstring bridge -> Romanian Deadlift + Load/45 degrees hip extension + Load/Unilateral hamstring bridge
What is the progression for short hip extensor exercises?
Bilateral hip thrust -> Unilateral hip thrust -> Unilateral hip thrust + speed/Bilateral hip thrust + load
What is the progression requirements for the Hip extensor and eccentric knee flexor exercises?
When full ROM completed with pain rated less than or equal to 4/10
What is the percentage associated with Stage 1 of a progressive running protocol
Stage 1 = 0 - 50% of maximal velocity
Low -> Medium -> Decel back to Low.
What is the percentage associated with Stage 2 of a progressive running protocol
Stage 2 = 50 - 80% of maximal velocity
Low aceler to medium -> Med/High -> Decel back to Low
What is the percentage associated with Stage 3 of a progressive running protocol?
Stage 3 = 80 - 100% of maximal velocity
Low aceler to High -> High -> Decel back to low
Askling Protocol
Hamstring Rehab Protocol
Exercise 1 - Lengthening
Exercise 2 - Strength and stabilization
Exercise 3 - Eccentric Strengthening
Pain Threshold Protocol
Protocol used for RTP
Criteria:
1. No TTP (tender to palpation) pain
2. No pain with active knee extension and SLR within 90% of contralateral limb
3. No pain during maximal effort isometric @ 0/0 and 90/90 degrees of hip/knee flexion
No pain or apprehension during spring @ 100% max effort
Pincer Lesion (FAI)
Extra bone extends out over the normal rim of the acetabulum. Labrum can be crushed under the rim of the acetabulum
Cam Lesion (FAI)
Femoral head is not round and cannot rotate smoothly inside the acetabulum. Bump forms on the edge of the femoral head that grinds the cartilage inside the acetabulum
Combined Lesion (FAI)
Both a pincer and cam lesion are present
FAI syndrome
Motion-related clinical disorder of the hip with a triad of symptoms, clinical signs and imaging findings. Represents symptomatic premature contact between the proximal femur and the acetabulum.
Primary symptom of FAI syndrome
Motion-related or position-related pain in the hip or groin. Pain may also be felt in the back, buttock or thigh. Pt may also describe clicking, catching, locking, stiffness, restricted ROM, or giving way.
When determining a surgeon for a Hip procedure, what criteria should be accounted for?
Number of surgeries. training, expertise
Phase 1 Characteristics
Weight-Bearing as tolerated (WBAT) with crutches for 3 weeks (limit to 20 pds with flat floot)
See ROM restrictions
Avoid Open-Kinetic Chain hip flexor activation + no SLRs in flexion
Phase 2 Characteristics
Gait Progression
Soft Tissue Work
Begin mobs at Week 5 (posterior and inferior)
WB exercises and strengthening
Phase 3 Characteristics
Return to function phase
More WB functional strengthening
Avoid WB rotation until Week 10 and agility until Week 16
Phase 4 Characteristics
Return to sport phase
Running program, agility, plyos initiated and used here
Return to Sport within 6-8 months
Problem Solving Approach
7 step process
- Understand patient’s participation restrictions and activity limitations
- Establish movement dysfunctions (global) - determine overuse/non-acute
- Establish impairments, tissues and joints involved, (local) identify diffs
- Establish stage of healing, irritability of tissues, problem lists
- Establish goals and plan -> pick tools in toolbox
- Establish baseline measures
- Treat and Reassess
The body is a natural cheater, what does this mean?
It will sacrifice quality for quantity
What does Sahrmann argue when it comes to Biomechanical muscle imbalance
Repeated movements and sustained postures can lead to adaptations in muscle length, strength, and stiffness
What do joints develop in the case of biomechanical muscle imbalance
Directional Preference
Changes in muscle length does what when it comes to biomechanical muscle imbalance?
Affects length-tension curve leading to stretch weakness and active insufficiency
What does Janda believe about Neurological muscle imbalance?
CNS and musculoskeletal system are interdependent
The muscular system is at a functional crossroads, True or False?
True
Characteristic patterns of muscle tightness and weakness lead to what in neurological muscle imbalance?
Pain and pathology of peripheral joints
Note to Kadin for Review
Look at Slide 9 of the Movement and Function Quality powerpoint because I can’t put the pic in the notecards
Janda’s Chronic Musculoskeletal Pain Cycle
Pain and inflammation -> Muscle imbalances -> Impaired movement patterns and posture -> Faulty motor programming -> Altered joint forces and proprioception -> Joint changes -> Repeat
Stable Joints of the body
Foot, Knee, Low Back, Scapula, and Elbow
Mobile Joints of the body
Ankle, Hips, T-spine, Neck, Shoulder, and Wrist
Mobility dysfunction can be broken down to 2 unique subcategories:
Tissue Extensibility Dysfunction and Joint Mobility Dysfunction
Tissue Extensibility Dysfunction
Involves tissues that are extraarticular.
Joint Mobility Dysfunction
Involved structures that are articular or intraarticular
Active or Passive Muscle Insufficiency
Tissue Extensibility Dysfunction
Osteoarthritis
Joint Mobility Dysfunction
Neural Tension
Tissue Extensibility Dysfunction
Subluxation
Joint Mobility Dysfunction
Fascial tension
Tissue Extensibility Dysfunction
Adhesive capsulitis
Joint Mobility Dysfunction
Muscle Shortening
Tissue Extensibility Dysfunction
Intraarticular loose bodies
Joint Mobility Dysfunction
Scarring
Tissue Extensibility Dysfunction
Fibrosis
Tissue Extensibility Dysfunction
Order of Evaluation
Dynamic to Static and Global to Local
Dynamic to Static Evaluation
Functional Movement Assessment
Gait
Static Posture Assessment
Global to Local Evaluation
Use Dynamic to Static assessments to identify joint specific assessments
Length/Tension/Strength of Tissues
Joint Motion and end feels of joints
Janda’s Approach
Normalize the Periphery
Restore Muscle balance
Increase afferent input to facilitate reflexive stabilization
Increase endurance in coordinated movement patterns
Athletes with an FMS composite score at 14 or below combined with a self-reported past history were at what risk of injury?
15 times increased risk
Before starting an FMS, what are steps to complete?
Measure tibia length, floor to top center of tib turberosity
Measure the hand length, distance from the distal wrist crease to the tip of the longest digit
How to score the FMS
Completed perfectly as verbally described, score of 3
Completed with compensation(s), score of 2
Unable to perform the pattern as described, score of 1
If there is pain with the movement pattern, score of 0
FMS steps
Squatting -> Stepping -> Lunging -> Reaching -> Leg Raising -> Push-Up -> Rotary Stability
Limitations with FMS
Not developed to be predictive (Causation versus association)
Limitations with reliability
More specific than sensitive (Better at ruling in than out)
Step Down Task
Have the patient step down from a 20 cm step and lightly touch the heel to the ground. Maneuver is repeated for 5 reps
Pt positioning for Step Down Task
Pt stands SL support with the hands on the waist, the knee straight and the foot positioned close to the edge of the step. Pt bends the tested knee until the contralateral leg gently contacts the floor and then re-extends the knee to the starting position.
Heel Raise
Testing for Forefoot Control
Normal - Some Varus
Abnormal - Excessive varus
