STANCE AND SWING PHASES OF RUNNING. STANCE SWING GOOD RUNNING FORM: what to look for? Minimal vertical displacement Cadence Lean forwards from the ankles Foot strike beneath body Compact arm positioning Relaxed shoulder girdle COMMON TECHNIQUE FAULTS Component Fault Correction Trunk incline/general posture •Excessive trunk lean forwards or backwards •General posture e.g. overextended •Slight forward inclination •“Imagine running into a stiff breeze” •“Ribs down” •“Chest out” Arm swing •“Opening up” arm swing: arms > 90 degrees, or away from body •Hand grip tight •Arms close to body around 90° •“Hands to pockets” •“Potato chip hold” Hip flexion/extension •Inadequate or poorly timed hip flexion/extension •Paw-back Stride length •Over-striding: initial foot contact in front of body’s centre of gravity •Land with feet under body •Correct cadence FUNCTIONAL IMPAIRMENTS: POSTERIOR VIEW • Pelvis/hip/knee: • • • • • Pelvic heights Femoral rotation Hip/knee angle Trendelenberg – a weakness of hip abductors (gluteus medius/minimus) on one side causing contra-lateral lateral drop of pelvis Foot/ankle: • • Normal pronation is 6-8 degrees with resupination Over pronation of ankle/foot – a rolling out of the heel relative to the leg +/- a collapse of the arch, leading to late re-supination for push-off FUNCTIONAL IMPAIRMENTS: LATERAL VIEW Pelvis/hip: Normal anterior/posterior tilt – 11° anterior rotation, 15° with leg extension Excessive anterior tilt of pelvis –muscle imbalances of the hip flexor/extensor muscles, reduced core control Knee: Excessive knee flexion in land Poor strength/co-control of quads/hamstrings Foot/ankle: Dorsiflexion control Listen for “foot slap” Reduced control often from calf tightness +/tibialis anterior weakness/poor control COMMON RUNNNG INJURIES Component Common diagnoses Possible impairments Spine • Non Specific Low Back Pain (NSLBP) • SIJ pain • Pelvic dysfunction • Rib pain/subluxation • Poor TVA/Oblique ratios • Imbalance through oblique slings • Hypomobile spinal segments • Poor spinal awareness •Tight and short H/S/QL/ES Hip • Gluteal tendinopathy • High hamstring tear/ensethop’ • Femoroacetabular imp’ • Labral tears • Weak glutes (Neuro/Strength) • Tight ITB/Overactive TFL/ADD • Overactive and short H/S • Poor ant oblique sling co-ord Knee • PFPS/ITBFS • Degenerative meniscal tears • Patella tendinopathy/bursitis • a/a • Weak or poorly timed VMO • Poor patella position/movements Foot/Ankle • Plantar fasciitis • Achilles/Peroneal/Tib Post tendinopathies • Poor arch control/support • Poor footwear for level of intrinsic foot strength • Tight calves • LL biomechanic (check a/a) REAL TIME ULTRASOUND IMAGING VIDEO ANALYSIS STRATEGIES FOR CORRECTING IMPAIRMENTS AND TECHNIQUE Strength and/or endurance Functional re-education Part practice Whole practice QUESTIONS?
