What does current evidence suggest for Physical Therapy intervention in the management of Posterior Tibial Tendon Dysfunction? March 14, 2012 Alana Gorman
What’s Happening for the next 30 mins • Review of normal m. & tendon • Description of what PTTD is/involves • Description of stages • Patient presentation • Current best evidence for intervention
Posterior Tibialis…Tibialis Posterior… either way it’s an important muscle! • Dynamic stabilizer of the arch • Most powerful inverter of the foot • Plantar flexes and inversion the ankle, adduction of the foot Gluck et al.
PTT Dysfunction • Recent literature describes it as a degenerative process • Patients suffer pain and fatigue with daily activities, walking & standing • Risk factors include trauma, overuse, HTN, Obesity, DM • Progression: spring ligament failure ->deltoid lig->talocrurallig-> bone breakdown
Secondary Hypotheses • Spring Ligament dysfunction • Supports medial arch of the foot • TalocalcanearInterosseus Ligament • Binds the talus and calcaneous • Accessory navicular bone • Type 1: ossicle w/in PTT • Type 2: sits on near tuberosity of navicular • Type 3: fused to tuberosity of navicular
Stage I Typical Patient : young runners, early onset of condition Presentation Structure: no deformity Strength: mild weakness w/ SL heel raise, mild weakness w/ inversion CC’s: medial pain, edema, tenderness along PTT
Stage II Presentation Structure: flexible pesplanus deformity, “too many toes”, RG’s show lat. talocalcaneal angle Strength: moderate weakness of SL heel raise, inversion CC’s: tenderness, swelling
Stage III & IV Presentation Structure: Fixed deformity Strength: Definite weakness, unable to perform SL heel raise CC’s: increase in s/s, pain @ calcaneofibular articulation Stage IV Presentation Structure: valgus tilt of talus, lateral tibiotalar degeneration
Stage III & IV • Resolution requires surgical intervention • Talonavicular arthrodesis/fusion • Medializing calcaneal osteotomy • FHL, FDL tendon transfer to support the arch Popelka et. al.
Patient Exam for PTTD Signs & Symptoms • Pain & Swelling • ROM • DF w/ knee flexed & extended • Subtalar joint motion; ranges from hyper-hypo mobile • Increased 1st Metatarsal DF suggests midfoot instability • Loss of medial longitudinal arch height • Strength • Postion: pt. PF, abd & everted • Pt. asked to move into PF, add & inversion • Single Heel Rise Test • Gait • Note forefoot abd, “too many toes” • Note heel valgus • SL heel raise, walk on toes
Treatment-EdUReP • Educate • Tendon healing occurs slowly, long recovery • Unload • Activity modification, foot orthosis • Reload • Eccentric exercises • Prevent • Stop the advancing deformity
Methods for Unloading Taping Technique for Medial Arch Support Franettovich et. al.
Methods for Unloading • Orthotics • Custom made (Kulig et. al.) • Medial heel lift • Medial Arch support • Bracing • AirLiftPTTD brace: clamshell ankle, air bladder@ midfoot(Neville et. al.) • Double Upright AFO (Lin et. al.) • Arizona Brace AFO (Augustin et. al.) • Shell Braces
Research • Bowring et. al. • Literature review in 2007 showed much discrepancy and limited evidence that supported good outcomes from specific interventions • No good evidence supporting US, DTM, TFM, Ice therapy, anti-inflammatory meds • Support for rest, orthotics, strengthening exercises for TP & periankle mm., stretching for gastroc-soleus complex, weight loss, and pt. education
Reloading Research Kulig et. al-Jan 2009, RCT • 3 groups, 12 participants each: • Orthoses & stretching • Orthoses, stretching & concentric exercises • Orthoses, stretching & eccentric exercises • Inclusion Criteria: • pain for 3+ months • symptoms located at the medial ankle or foot • Tenderness to palpation specific to the tibialisposterior tendon • foot flattening • abducted midfoot • absence of rigid foot deformity
Reloading Research • Interventions-3 months • Orthoses • All groups • Stretching • All groups • Progressive Resisted Ex • Concentric (Group II) • Eccentric (Group III) • Outcome Measures • FFI • 5 minute walk test • VAS Kuliget. al.
Results Orthoses w/ Concentric Orthoses w/ Eccentric Average resistance 12.5 lbs 2.6% average increase in 5MWT Significant change in VAS FFI decrease 15 total 36.3 pain 40.5 disability 8 activity limitation • Average resistance 3.7 lbs • 13.2% increase in 5MWT • Significant change in VAS • FFI decrease 10.9 total • 11.8 pain • 17.8 disability • 3.3 activity limitation Kuliget. al.
Reloading Research • Kulig, et. al. Sept 2009 : Case Series • 10 subjects • 2 weeks unloading, 10 weeks of eccentric exercise program • Considered morphology & vascularization of tendon before/after program. Assessed pain & function @ 6 mo follow-up • OM’s: FFI, VAS, 5MWT, Single Heel Raise, PAS, GRS
Results • 12 weeks: POST • 100% retention, 77-100% compliance • (mean 95%) • Significant increase in # of heel rises • (6.3 ± 3.7) to (11.1 ± 4.7) • Significant decrease in FFI (pain & disability) • (31.1 ±15.8) to (11.4 ± 9.9) • Tendon degeneration remained present at end of program • 6 month follow-up: 6M • No significant difference between POST & 6M in FFI • GRS results achieved MCID in decrease of symptoms • (5.2 ± 0.92).
Methods for Reloading “TibPost Loader” Exercise device (TibPost Loader) designed to provide progressive, constant resistance (2) throughout the range of motion in the transverse plane. The hand lever (3) allows for selective application of the resistance in one direction only. When the foot resists the footplate’s motion towards horizontal abduction, the tibialis posterior is recruited eccentrically. To minimize the activity of the anterior tibialis the patient applies pressure into plantarflexionas indicated by LEDs (1). C, Elastic band provides resistance eccentrically to the tibialis posterior throughout the range of motion. Note the towel under the forefoot to decrease friction and the direction of the elastic band, ∼45 degrees to floor, to resist adduction and plantarflexion. Kuliget. al.
Take Homes • UNLOAD first: stretch PF, rest, brace & support • Orthoses & stretching alone significantly reduced self reported pain, disability and activity limitation after 3 months • No increase in symptoms occurred w/ eccentric or concentric loading of the tendon • Greater training load achieved w/ eccentric ex (3x as much!) • Tendon repair/remodeling takes longer than 10 weeks!
Take Homes National Clearinghouse Guidelines-2007 • Special investigations [D] • MRI better at differential diagnosis of medial ankle/foot pain • US may be useful • Radiographs indicated if unrelieved by 4 weeks of conservative care or in suspected inflammatory arthritis [D] • AP, medial oblique, and lateral foot radiographsAdditional views: Weight-bearing ankle series may be useful
So what does the current best evidence say? • High rep • Low load • Progress as tolerated • Stretch!! • Support!! • Thank you!
