Standardizing the approach to evidence-based upper limb rehabilitation after stroke

How did these researchers get past the meme, 'All strokes are different, all stroke recoveries are different'? to create some standards? They need to be shot as heretics. Its only 9 pages long, maybe your doctor can get it instituted in the next 10 years.

Abstract: Study describes the development of a clinical algorithm to enable standardized intervention prescription and progression for hemiparetic upper-limb rehabilitation following stroke. The standardized clinical algorithm involved assessment of 18 critical impairments of upper-limb function and application of task-specific exercises appropriate to the individual’s level of impairment. These tasks were consistent with recent evidence-based guidelines. Feasibility was tested with 20 participants recently discharged from inpatient rehabilitation following stroke who received outpatient therapy according to the clinical algorithm. Participants’ abilities were regularly re-evaluated and task difficulty progressed. Outcomes were assessed at the level of impairment (Action Research Arm Test, Fugl-Meyer Assessment) and activity (Motor Activity Log). All participants attended the 9 sessions of training over the 3-week intervention period. No adverse events were reported. There were significant improvements in all outcome measures. This evidence-based, upper-limb clinical algorithm provides a framework for standardizing task-specific training following stroke based on the assessment of functioning of the individual following stroke in day-to-day life. This approach is appropriate for patients with different functional levels and may be used to standardize individual or group self-directed practice sessions or to standardize the intervention and progressions in experimental studies.
