  1. Elastic Taping for Runner Injuries Huei-Ming Chai, PT PhD School of Physical Therapy National Taiwan University, Taipei, Taiwan June 23, 2008

  2. Elastic Taping for Runner Injuries • Kinesio tape and its properties • development of elastic taping • advocated effects of elastic taping • principles of application • Q and A • Common Runner Injuries and its Taping

  3. Kinesio Taping • 1973 Kenzo Kase, D.C. • concept for development: to provide a better environment for self-healing • feature • elastic: able to be stretched up to 140%

  4. Advocated Effects • to re-adjust muscle tension • to improve blood/lymph circulation • to relieve pain • to re-align joint position • to provide skin stimulation

  5. 背襯 膠 皮膚 Structure of Tape • backing material (背襯) • porosity (透氣性) • conformability (順膚性) • adhesive (膠): 醫療等級 • rubber based (乳膠系) • zinc oxide (氧化鋅系) • silicone based(矽膠) • acrylate based (丙烯酸膠、壓克力膠): pressure-sensitive (感壓膠) • release agent (解捲因子)

  6. Applied Force of Elastic Tape • stress-strain curve • creep phenomenon • commonly used • zero tension: 100-110% of length • moderate tension: 120% of length • full tension: 140-150% of length

  7. total tension passive tension active tension tension length resting length Length-Tension Curve-- maximum isometric contraction

  8. Tensile Strength of Collagen Fiber plastic region failure yield point elastic region strain microtrauma injury clinical test physiological loading ultimate strain stress

  9. As deformation remains constant stress time Load Relaxation • Progressive decrease in load with time as the deformation of the structure remains constant

  10. Applied Shape of Elastic Taping Y-band I- band x-band fork-shaped

  11. parallel perpendicular Applied Position of Elastic Tape • commonly used • parallel to the fibers: for support • perpendicular to the fibers: for fixation

  12. recoil of tape recoil of tape muscle contraction muscle contraction direction of taping: insertion to origin direction of taping: origin to insertion Applied Direction of Elastic Tape

  13. Other Considerations of Application • site to be applied • muscle • ligament • lymph note • size of tape • position of adjacent joints

  14. Failure of Kinesio Taping • unable to hit the target • incorrect diagnosis • poor palpation • Inaccurate alignment of muscle • forget to place the injured tissue in the lengthening position

  15. Q and A • How long it can be applied onto the skin? • Is it water-proof? • Is it appropriate for the hypersensitive skin? • Can it be used accompanying with other types of physical therapy? • Do I need to shave hairs before application of elastic tape? • Are there any differences among the tapes with various colors? • Can I used it for a healthy adult?

  16. Elastic Taping for Runner Injuries • Kinesio tape and its properties • Common Runner Injuries and its Taping • heel pad pain syndrome • plantar fasciitis • Achilles tendinitis • iliotibial band syndrome • patellofemoral pain syndrome • low back pain

  17. foot strike mid-support take-off follow-through forward swing foot descent Running Cycle • stance phase • swing phase

  18. gel heel pad Shock Absorption at Foot Strike • ground reaction force at FS = 2.5～3BW • biomechanical requirements at FS • LE motions • cartilage or fat pad • heel pad, metatarsal pad, meniscus, IVD • extrinsic factors

  19. Heel Pad Atrophy atrophy use of heel cup Poor recoil

  20. Elastic Taping for Foot 1. plantar fascia 2. heel pad 3. arch support

  21. Foot Motion during Mid-Support • foot pronation at mid-support in order to make the foot more mobile for further shock absorption • foot pronation  medial and inferior glide of talus and internal rotation of tibia  COG shifting medially   energy consumption and time to re-supinaiton • strategy: hard counter for controlling COG motions counter

  22. 4.6 cm 3.0 cm Pronated Foot • pronation of rearfoot with respect to forefoot (decreased arch) as foot is loaded • NOT structural flat foot • resulting in pain or dysfunction of foot or other WB joints NWB WB

  23. Achilles Tendinitis • etiology: Achilles tendon tightness • predisposing factors • sudden change in intensity • uphill running • S/S • Achilles tendon pain or stiffness • unable to raise on the heel, deep squatting, or stretch Achilles tendon • enlargement of Achilles tendon

  24. Architecture of Gastrocnemius • Changing fascicle angle improves muscle performance? • confinement? Gas m.

  25. plantar fascia arch support Arch Support in Pronated Foot • pronated foot  lower arch  plantar fascia stretched • A arch support would further stretch plantar fascia

  26. Re-supination at Take-off • re-supination at take-off in order to make the foot rigid and support the body weight • LE motions：subtalar joint supinaiton、midtarsal joint locked, first ray plantarflexion, and MP joint full extension • windlass effect of plantar fascia •  ground reaction force   momentum (= mv) •  running speed •  impact force (= Ft) accumulated at metatarsal heads  metatarsalgia

  27. plantar fascia plantar fascia Windlass Mechanism (Truss Model) Toe neutral PF of 1st ray Toe extension

  28. Plantar Fasciitis neutral foot pronated foot plantar fascia

  29. Elastic Taping for Foot 1. plantar fascia 2. heel pad 3. arch support

  30. Patellofemoral Pain Syndrome • chondromalacia patella • anterior knee pain, esp. downstairs • positive grinding test • management • PT • arthroscopy • quadriceps strengthening • elastic taping

  31. ITB Iliotibial Band Friction Syndrome • Iliotibial Band • origin：insertion of tensor fascia lata • insertion：Gerdy’s tubercle of tibia • S/S • lateral knee pain • pain at 15-30 of knee flexion during one-leg squatting test • Management • stretch exercise • elastic taping

  32. Elastic Taping for Back Muscle Spasm • Patient’s position • forward bending with elbow on the knee • Type of taping • I- band for paravertebral muscle

  33. Rotator Cuff Tendinitis • S/S • shoulder stiffness, pain, or weakness • unable to raise the arm or put the hand on sacrum • drop arm test • differentiation • supraspinatus • infraspinatus • teres minor • subscapularis • long head of the biceps brachialis

  34. Elastic Taping for Supraspinatus

  35. Elastic Taping for Deltoid Muscle
