Document Summary
Rom: goniometry, assesses joint rom, stiffness & resistance movement, rom: difference b/w joint angles measured at extremes of joint movement, goniometer. Posture & curvatures: postural assessment observations: important to know what to look for, body type, symmetries & alignments, observe from all perspectives, assess height differences b/w anatomical landmarks, visualise whether everything lines up. Sway back: pelvis does not have anterior/posterior pelvic tilt (shunts forward, looks like an exaggerated lumbar forward curve, stress in lower thoracic/lumbar region (disc herniation or sciatic pain) 4: no tilt pelvis shifts forward major, weak/lengthened spine flexors: rectus abdominis, obliques, transverse abdominis & psoas, tight spine extensors: erector spinae. Hip: peak hip (hyper)extension occurs before toe off, adequate flexion necessary during swing phase to facilitate foot clearance & adequate step. Initially flexed at foot, contract, then progressively moves into extention length: hip rom ~40 .
