PT 726 Running Gait Analysis

what percentage of the gait cycle is stance

60

what percentage of the gait cycle is swing

40

what aspect of the gait cycle do we focus a lot on for runners

- initial contact

- mid stance

- mid-swing

_____ is when the foot makes contract with the ground and begins to rotate to foot flat to preserve progression, hip and knee are flexed while other foot remains on groun

IC

___ is when the foot falls flat on the round, more knee flexion will occur, hip moves into extension, while other foot remains on ground

LR

what are the goals for IC and LR

- limb stabilization

- shock absorption

- preserve progression

_____ is when the femur rotated internally, stance leg is directly over the foot and swing thigh parallel to stance thigh

mid stance

_____ is when COM continues forward over the stance foot, hip and knee are extended, heel starts to come off ground and weight is shifted to ball of the foot

terminal stance

what is the goals of mid stance and terminal stance

- forward progression of the body

- stability during weight bearing

______ is when foot of stance leg is pushing off the ground and IC has occured on swing limb

pre-swing

_____ is when the ankle, knee, and hip are all flexed in preparation for forward progression and clearance of the foot

initial swing

____ is when the forward progression continues and thigh reachers maximum advancement forward, knee and foot are still flexed

mid swing

____ is when the knee and hip remain flexed, forward progression of the tibia is still happening foot is preparing for contract with the ground

terminal swing

what are the goals for the swing phase of gait

- foot clearance

- forward swing of limb

- preparation for stance

what are reasons some people over pronate

- lack of tibial mobility

- decreased strength in foot/posterior tib

- lack of femoral mobility

____ percent of runners will experience shin splints

20%

shin splints make up about _____% of all lower extremity injuries

60

what should we do for our assessment for shin splits

- tuning fork to rule out fracture

what could be the differential diagnoses for shin splints

- gastroc/soleus tightness causing meidal tibial stress syndrome

- posterior tib irritation

where is gastrosoleus tightness most common

when ramping up miles/activity quickly or when switching to forefoot strike pattern

what is the treatment for shin splints

- soft tissue to gastrocsoleus, posterior tibs

- hip assessment

- SLS progression

what should be assessed if a patient complains of plantar fasciitis

-quadratus plantae

- abductor hallucis

- gatrcosoleus

what are the treatment areas for plantar fasciitis

- ankle Df

- toe yoga

- footwear assessment

- FDN quadratus plantae

what could possibly be impairements for IT band syndrome

- glute med activation

- decreased hip or/and knee ROM

- TTP fibular head

- knee and or hip pain

what are treatment options for IT band syndrome

- pelvis/hip stability

- ROM of hip/knee

- rule in/out spinal involvement

_______ is calculated by counting the steps taken on one leg over 60 seconds and doubled

cadence

it has been concluded that running at a step rate of ___ or below can increase your risk of injury by 7% compared to runners at ___ cadence or above

164;174

overstriding can cause

- shin and knee pain

how can we help with overstriding

increasing cadence

where do we want the tibal angle to be with striding

perpendicular (10 degrees or less 5 is best)

how much forward lean do we want with running

10 degrees

how much vertical displacement is normal with running

when is vertical displacement measured

- drawn at midstance high and lowest point of pelvis

how much knee flexion do we want at mid stance for running

if your patient is having trendelenburg during mid stance with running what can we look at to help improve

- contralateral QL (typically not a weakness issue, either poor activation or tightness)

what are the other factors that need to be considered with runners

- hydration start with 64 oz

- nutrition >90 grams of protien

- sleep 8 hours
