13.2 Motor Learning and Task-Oriented Neurorehabilitation

Motor Learning and Task-Oriented Neurorehabilitation

Choose a meaningful activity, measure what the person can do, then grade the practice to match their current ability. Measure immediate performance and later retention or transfer. A faster or smoother attempt with help can be useful even when unassisted ability has yet to change.

Experience-Dependent Plasticity and Motor Learning

Recovery after stroke can reflect spontaneous biological change, practice-dependent learning and compensation. These processes overlap. Animal studies have shown changes in surviving motor representations after skilled practice. Human studies can measure changes in movement or brain activity. Interpret them with the task, recovery stage and study design.

Select a meaningful task → observe baseline performance → grade and repeat practice
                                          ↓
                     Test again with less assistance or in another setting

The phase II Critical Period After Stroke Study compared the same additional upper-limb training dose at different times. The group starting at two to three months showed the largest measured gain compared with controls. Its result describes that trial and intervention. In acute ischemic stroke, plan rehabilitation around medical stability and stroke-unit guidance. High-dose mobilization within the first 24 hours can be harmful.

Kleim and Jones' Principles of Experience-Dependent Neuroplasticity

Use the ten principles as a framework for choosing and evaluating training.

Choose a task that allows successful attempts and room to improve. For example, use a higher chair for sit-to-stand practice, then reduce the height or the amount of hand support. Record repetitions, assistance, fatigue, perceived effort and the patient's response. Combine recovery-oriented practice with compensatory strategies when they improve safety or independence.

Constraint-Induced Movement Therapy (CIMT)

CIMT combines repeated practice using the more affected arm, shaping the difficulty, restricting the less affected hand during selected activities, and strategies to carry use into daily life. Learned non-use describes a pattern in which the person uses the more affected arm less often than observed capacity would allow. Pain, fatigue, environment and task demands can also explain the difference.

Observe arm capacity and daily use → check task and restraint safety
               ↓
Grade practice → plan use at home → reassess actual use and task performance

Selection and Dose

• EXCITE trial. Participants were enrolled three to nine months after stroke. The lower-functioning subgroup needed at least 10 degrees of active wrist extension, 10 degrees of thumb abduction or extension, and 10 degrees of extension in at least two other digits. The movements had to be repeatable three times in one minute. The higher-functioning subgroup needed at least 20 degrees of active wrist extension and at least 10 degrees of active extension at the metacarpophalangeal and interphalangeal joints of all digits. The trial also required safe balance and transfer capacity with the mitt.
• Intensive example. EXCITE scheduled up to six hours of supervised training on ten weekdays over two weeks and asked participants to wear the mitt during 90% of waking hours, with safety exceptions. Practice time was graded. Current Canadian guidance uses at least 20 degrees of active wrist extension and 10 degrees of active finger extension for its selected high-intensity group, alongside sensory and cognitive criteria.
• Modified example. Page and colleagues tested 30-minute sessions three days per week and five hours of restriction on five days per week for ten weeks in chronic stroke. Modified programmes vary. Very early high-intensity CIMT produced less improvement in the VECTORS trial than the lower-dose and usual therapy groups.

Assess active movement, pain, cognition, attention, safety, daily hand use and goals. Progress difficulty in achievable steps. Practice meaningful tasks and plan safe use outside therapy. A diary or Motor Activity Log can help distinguish arm use at home from performance in the clinic.

Walking Practice, Body-Weight Support and Robotics

Body-weight support through a harness can reduce the load during stepping and allow more practice with graded assistance. Spinal locomotor circuits, descending drive and sensory feedback all contribute to stepping. The clinical target is walking performance. Select support, speed, assistance and rest to enable safe stepping and active effort. Progress them using foot clearance, stance control, gait quality, fatigue and the patient's goals. Practice overground walking as well when feasible to check carryover.

The LEAPS trial found that treadmill-based locomotor training with body-weight support was similar to the tested therapist-managed home exercise programme for improving functional walking at one year. The 2026 AHA/ASA guidance prioritizes task-specific overground walking in ambulatory people and gives no preference to light-to-moderate treadmill or robot-assisted gait training over that practice. NICE and Canadian guidance allow a treadmill as an option or adjunct in suitable people. Robotic systems can help deliver repeated stepping when the team can provide appropriate assistance and monitor progress. Measure performance outside the device as well as during training.

Functional Electrical Stimulation (FES)

FES times stimulation of peripheral motor axons to assist a functional task. For post-stroke foot drop, a sensor may trigger stimulation through electrodes near the common fibular nerve to support dorsiflexion in swing. Check that stimulation gives useful foot clearance, and compare walking with FES and with an ankle-foot orthosis when either option is appropriate. Improvements with the device on and unassisted changes over time are distinct outcomes.

In upper-limb training, stimulation can assist wrist or finger extension during practiced grasp and release. Choose muscles, timing and assistance by the movement observed and record performance with and without assistance.

Cues, Practice Order and Feedback

An internal focus directs attention to a body movement, such as straightening the elbow. An external focus directs attention to the intended movement effect, such as sliding a cup to a line. Try a cue the patient understands and compare its effect on task performance. Stroke studies have reported varying results by task and patient. Assess retention before judging the learning effect.

Blocked practice groups repetitions of the same task. Random practice interleaves different tasks or variants. Interleaving improved retention of one upper-limb sequence in a small chronic stroke study. Start with a task order that allows safe, useful repetitions and add variety when it serves the learning goal. Schedule rest to manage fatigue and preserve performance.

Knowledge of results describes the outcome. Knowledge of performance describes the movement. Give enough feedback for safety and understanding, then assess performance as the patient works with fewer cues. A faded schedule progressively reduces frequency. Summary feedback is delivered after several attempts, and bandwidth feedback is linked to errors beyond an agreed threshold.

Worked case. Six months after stroke, an accountant demonstrates 20 degrees of active wrist extension, 15 degrees of thumb abduction and 15 degrees of active extension at the metacarpophalangeal joints of the index and middle fingers. She seldom uses that hand at home. Check repeatability, pain, sensation and restraint safety before selecting a CIMT programme. Ask what limits hand use and start with meaningful pen and keyboard tasks. Try an external cue such as “Slide the pen into the holder.” Compare practice performance with use at home and test retention with less cueing.
