‫السالم عليكم و رحمه الله و بركاته‬  Ahmed Torad, PhD, PT, Cairo university, 2020 Presente lecturer, Basic Science department, d by Faculty of Physical Therapy, Kafrelsheik  Still talking about kinematic analysis Week Lecture Practical Getting started  Introduction about studying biomechanics ii Week 1  Revision on COG, stability, forces and torques, and force systems Biomechanics of gait Gait 1  Illustration of gait cycle Gait cycle  Applications of temporal and Week 2 Spatial and temporal gait spatial analysis of gait analysis) Gait 2  Applications on joints ROM during gait Week ROM during gait cycle 3  Analysis of lower limb joints ROM Measurement of Joint angles of lower extremities (hip, knee, and ankle) in sagittal plane (flexion or extension), frontal plane (Abduction or adduction) and transverse plane (internal or external rotation)  Hip joint ROM in sagittal plane A- Stance phase: 1- Initial contact: hip joint is flexed 30˚ and flexion decreased from this phase throughout the stance. 2- Loading response: flex reaches 25˚ 4- Terminal stance: from midstance to terminal stance, the hip is moving to hyperextension until reaches 10˚-20˚ at the end of terminal stance (arc of hip ext). B- Swing phase: Initial swing: hip flexion 20˚. Midswing: hip flexion increases till reaches 30˚ flexion (arc of hip flexion).  knee joint ROM in sagittal plane A- in stance phase: 1- Initial contact: knee is flexed 5˚ only. 2- Loading response: knee flexed from 15˚-20˚ (first arc of knee flexion). 3- Midstance: 5˚ of flexion at the end of midstance. 4- Terminal stance: 0˚ knee flexion (first arc of knee extension) 5- Preswing: 35˚-40˚ B- in swing phase: 1- Initial swing: 40˚- 60˚ flex. 2- Midswing: knee flexion reaches to maximum (60˚-65˚) (second arc of flex).  Ankle joint ROM in sagittal plane A- in stance phase: 1- initial contact: in neutral position. 2- loading response: 15˚ plantar flexion (first plantar flexion arc). 3- midstance: directed to 4- Terminal stance: dorsiflexion reaches to the maximum ( 10˚) (first dorsiflexion arc). 5- preswing: at the end of this stage maximum plantar flexion 20˚-30˚ B- In swing phase: 1- Initial swing: 10˚ of ankle plantar flexion. 2- Midswing: 0˚ of ankle dorsiflexion (second arc of ankle dorsiflexion).  ankle kne hip pha e se neutral flex 5 30 IC flex plantar 15 15-20 25 LR (1st arc 1st( flex plantar) arc (fex dorsi 5-10 flex 5 0 MS dorsi (1st 10 ext 0 20 10 TS arc dorsi) (1st ext arc ext) (arc ext) 20-30 35-40 neutr PS planter (2nd flex al plantar arc) planter 10 40-60 20 IS flex flex  Hip joint ROM in frontal and transverse planes At initial contact, the hip is adducted about 10˚. At loading response: adduction is 5˚ In mid and terminal stance returns to neutral position. In initial swing hip abduction by 5˚ occurs. Hip ROM in transverse plane: external ( at swing)  knee joint ROM in frontal and transverse planes In frontal plane: During stance the motion is abduction. Adduction occurs during swing phase and reaches 8˚. Knee joint ROM in transverse plane: In transverse plane: External rotation occurs at stance phase and internal rotation occurs at swing phase. Average degree of rotation is 9˚-13
