Movement Science Unit 13 Taping and Bracing Flashcards
What causes Patellofemoral Pain Syndrome (PFPS)?
What aggravates this?
Abnormal biomechanics in LE kinetic chain
Aggravated by:
- Prolonged sitting (“Movie goers sign”)
- Squatting
- Stair climbing
- Stair descending
What are the S/S of Patellofemoral Pain Syndrome?
- Pain worse with walking, squatting, kneeling, running and/or sitting
- Swelling in the knee
- A grinding or popping sensation
- “Knee buckling” occurs when knee cannot bear weight
With PFPS, what direction would the paterlla track if there was Patellofemoral instability?
Usually tracks in a lateral direction
What can Patellofemoral Pain syndrome cause? What are the can be done for treatment?
Causes:
- Decreased hip strength
- Decreased quad strength
- Poor patellar tracking
- Ankle mobility (Hypo/Hyper)
Treatment:
- Strengthen gluteals
- Strengthen quads
- Patellar taping/brace to increase or control ankle motion
What are the Normative Q Ankle values for men and women?
What can a High Q Angle cause?
Men: 13°
Women: 18°
This causes the quads to pull on the patella, which leads to poor tracking predisposition for pain
What are the structural variables that increase the Q-Angle?
- Coxa vara
- Femoral antertorsion or Femoral IR
- Genu Valgus
- External Tibial Rotation
- Lateral Displacement of the Tibial Tuberosity
- Pes Planus, Calcaneal Eversion, Hind-foot pronation
We cannot truly assess the Q-Angle if the patella is out of position. Use the trochlear groove between the medial and lateral femoral condyles
What are the forces at the Patellofemoral Joint?
- As the knee flexes, the contact areas move proximally on the undersurface of the patella
- Ideally, in full extension there is no patella to femur contact
What is the relationship between Patellofemoral Joint and Joint Reaction Forces?
As the quad force increases, the Joint Reaction Force Increases
At what degrees in the Patellofemoral Joint under the greatest stress?
- Greatest in Closed Chain Squat at 90°
- Least amount in Close Chain < 45°
- OKC EXT-VR lowest at 90° - steadily increases at the knee extends
- OCK EXT-CR (isokinetic machine) under constant stress throughout with peak stress at 0°
OKC = Open kinetic Chain
Proper Patellar Tracking is Dependent on the Integrity of what structures?
- Medial Retinaculum
- VMO sufficiency
- Prominent lateral femoral condyle or normal trochlear groove
What are some Factors that produce Abnormal Patellar Alignment and Motion?
- Anything that increases the Q-Angle
- Tight/weak Rectus Femoris
- Tight TFL and IT Band
- Weak VMO
- Weak Hip Stabilizers
- Hind-foot pronation
- Excessive pelvic tilt
What are the 3 Main Taping Techniques recognized within the therapeutic community?
- Prophylactic Athletic Taping
- McConnell and Mulligan Taping
- Kinesiotaping Method
Why should Therapist use Prophylactic Athletic Taping?
- Limits or assist motion in ACUTE injurines or injury prevention
- Compressive force to the skin, joint and muscles
- This may require pre-tape or adhesive
- Has a limited wear time
- Often contains latex
Not rehabilitative
Why should therapist use McConnell and Mulligan taping?
- Limits normal ROM
- This requires combination of tapes: extremely rigid tape placed over a cotton mesh
- This has a limited wear time
- Joint strapping with limit pathological movement
- Latex and non-latex adhesives
With McConnell Taping, If we are trying to correct the Patellar Position of Lateral Glide, where would we apply the tape?
We would apply tape to Lateral Border of the patella
With McConnell Taping, If we are trying to correct the Patellar Position of Lateral Tilt, where would we apply the tape?
We would apply tape to Middle of Patella to Medial Femoral Condyle (MFC)
With McConnell Taping, If we are trying to correct the Patellar Position of External Rotation, where would we apply the tape?
We would apply tape to Middle of Inferior border of Patella to MFC
Why should a therapist use Kinesiotaping?
- This type allows practitioner to target specific tissues
- Allows normal ROM
- Its therapeutic benefits are achieved by tissue glide, decompression, or compression
- Can be worn 3-5 days with “good skin tolerance”
With Kinisiotaping, we should use a test patch (1-2 blocks with no tension in the abdomen or treament area. Evaluate the sensitivity after a few hours or days)
What are the benefits of Kinesiotaping?
- It Mechanically Decompresses the skin and the underlying tissues it is applied to
- It stimulates all sensory nerves in the skin and underlying tisseus
- Tissue decompression relieves pressure, allows better circulation and reduces swelling at the site of the injury
What are the Contraindications of Kinesiotaping?
- Fragile or healing skin
- Malignant sites
- Cellulitis or infected areas
- Known taping allergies
What are the precautions for kinesiotaping?
- DM
- Kidney disease
- CHF
- Asthma
- High or low blood pressure
- Open wounds
- Pregnancy
Before using Kinesiotape, how should the skin be prepaired?
- The skin should be clean and dry
- The skin should be free from oils or creams
- The skin should be clipped or shaved if there is any dense or matted hair
What are the K-Tape Basic Cuts?
K-Tape Terminology
What is the Anchor?
The beginning of application, 0% tension applied in neutral position
