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 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 ) 背襯 膠 皮膚

6 Applied Force of Elastic Tape stress-strain curve creep phenomenon commonly used –zero tension: % of length –moderate tension: 120% of length –full tension: % of length

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

8 Tensile Strength of Collagen Fiber stress strain plasticregion elasticregion injury microtrauma physiologicalloading failure yield point clinical test ultimate strain

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

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

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

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

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

18 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 gel heel pad

19 Heel Pad Atrophy use of heel cup Poor recoil atrophy

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 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 4.6 cm WB 3.0 cm

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 Gas m. Changing fascicle angle improves muscle performance? confinement?

25 pronated foot  lower arch  plantar fascia stretched A arch support would further stretch plantar fascia Arch Support in Pronated Foot arch support 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 Windlass Mechanism (Truss Model) Toe neutral Toe extension plantar fascia PF of 1 st ray

28 Plantar Fasciitis plantar fascia pronated foot neutral foot

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 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  of knee flexion during one-leg squatting test Management –stretch exercise –elastic taping ITB

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
