title: Knee posture during gait and global functioning post-stroke: a theoretical ICF framework using current measures in stroke rehabilitation.
abstract: OBJECTIVE
  To characterise the global functioning post-stroke in patients with normal knee posture (NKP) and abnormal knee posture (AKP) during loading-response.
  
  
  METHODS
  35 people, 6 months post-stroke. with NKP and AKP were identified and assessed using clinical measures classified into the corresponding International Classification of Functioning, Disability and Health (ICF) domains: weight function (body mass index); muscle power (knee isometric strength); muscle tone (Modified Ashworth Scale); voluntary motor control (Leg sub-score of Fugl-Meyer scale); walking short distances (5-meter walk test; Timed-Up and Go test); walking on different surfaces (Functional Ambulation Categories); moving around (Falls Efficacy Scale); moving using equipment (walking aids) and global assessment of function (WHODAS II). Age, gender, marital status, current occupation and caregivers support characterised personal factors.
  
  
  RESULTS
  Patients with AKP had significantly lower knee flexor strength, higher knee flexor and extensor spasticity, more difficulty in maintaining a standing position, walking short and long distances, used walking aids more often and needed more caregiver support. Restriction in activities and participation were correlated with knee flexor strength for AKP and with knee spasticity for NKP group.
  
  
  CONCLUSIONS
  AKP restricts functioning and participation.
