During forward-induced protective stepping, otherwise healthy older adults who had experienced falls showed particular differences in their control of lateral body motion that were not attributable to changes in anticipatory postural mechanisms. Aging changes in controlling lateral body motion during protective stepping appear to involve factors that intervene between the first-step liftoff and foot contact and/or adaptations in stepping patterns related to prior planning.
Physical therapists must screen all individuals who have experienced a potential concussive event and document the presence or absence of symptoms, impairments, and functional limitations that may relate to a concussive event.
Screening for Indicators of Emergency ConditionsA Physical therapists must screen patients who have experienced a recent potential concussive event for signs of medical emergency or severe pathology (eg, more serious brain injury, medical conditions, or cervical spine injury) that warrant further evaluation by other health care providers. Referral for further evaluation should be made as indicated (FIGURE 1).
Differential DiagnosisA Physical therapists must evaluate for potential signs and symptoms of an undiagnosed concussion in patients who have experienced a concussive event but have not been diagnosed with concussion. Evaluation should include triangulation of information from patient/family/witness reports, the patient's past medical history, physical observation/examination, and the use of an age-appropriate symptom scale/checklist (see FIGURE 1 for diagnostic criteria).
A classification scheme that can distinguish between four categories of bipedal to single-limb stance transitions has been established. Issues concerning clinical assumptions pertaining to the relationship between static and dynamic motor dysfunction in adults with hemiparesis are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
