IRAT 6

Primary reason to lock wheelchair brakes before transfers

To prevent unexpected wheelchair movement and reduce the risk of falls during transfers between surfaces.

Footplate and footrest management before wheelchair transfers

Swing away or remove the footrests and raise footplates; never allow the client to stand or bear weight on footplates.

Caregiver safety precautions before pushing a wheelchair

Notify the client before moving; confirm that elbows do not protrude beyond armrests, hands are clear of hand rims, and feet are safely positioned.

Caregiver technique for ascending a ramp with a wheelchair

Push the wheelchair forward up the incline while maintaining controlled forward momentum and safe body mechanics.

Trunk positioning for independent ramp ascent in a manual wheelchair

Lean the trunk slightly forward to assist with propulsion and maintain stability on the incline.

Caregiver technique for descending a slightly graded ramp facing forward

Grasp push handles, tilt the chair slightly backward onto rear wheels, and move forward with controlled speed (client may assist via hand rims).

Caregiver technique for descending a steep ramp

Move backward down the incline with the chair while controlling the large wheels to avoid uncontrolled rolling.

Independent wheelchair descent on a steep ramp

Lean slightly backward and control speed via hand rims; traverse diagonally across the ramp if steep, using push gloves to reduce friction.

Key caregiver body mechanics when maneuvering a wheelchair on ramps

Keep knees slightly bent, maintain a straight or neutral spine, and execute deliberate, controlled movements.

Caregiver technique for ascending a curb with a wheelchair

Tip the wheelchair backward to elevate front casters onto the curb, roll rear wheels forward against the curb, then lift and roll rear wheels up.

Caregiver technique for descending a curb with a wheelchair

Turn the chair backward, lower the rear wheels down under control, tip back onto rear wheels to clear front casters, and lower casters gently.

Independent curb ascent sequence in a manual wheelchair

Perform a controlled wheelie, place front casters onto the curb, lean forward, and forcefully push the rear wheels up over the edge.

Independent curb descent sequence (backward method)

Lean trunk forward and back down slowly using the hand rims so rear wheels descend first, followed by a controlled landing of front casters.

Physical and functional prerequisites for independent wheelchair wheelies

Bilateral grip and upper-extremity strength, motor coordination, dynamic sitting balance, and formal wheelchair skill training.

Wheelchair axle adjustment that increases rearward tipping risk

Positioning the rear axle too far forward relative to the user's center of mass.

Functional purpose of executing a wheelchair wheelie

To elevate front casters to clear obstacles such as curbs, thresholds, and uneven terrain including grass, gravel, or sand.

Comprehensive scope of a patient transfer

Encompasses pretransfer preparation (such as bed mobility), movement between surfaces, and post-transfer alignment (such as safe wheelchair seating).

Assessment factors determining appropriate transfer technique

Physical, cognitive, perceptual, and behavioral capacities; medical precautions; safety judgment; and clinician lifting capacity.

Core principles of safe therapist body mechanics during transfers

Stay close to the client, face the client, bend at knees, lift with legs, maintain a wide base of support and neutral spine, and avoid twisting while bent.

Clinical rationale for maintaining equal transfer surface heights

Level surface transfers simplify movement and biomechanical load; downhill transfers require less effort, whereas uphill transfers demand greater work.

Standard wheelchair positioning angle relative to transfer destination

Approximately $30^\circ$ to the target surface, adjusted based on the transfer method and physical assistance requirements.

Wheelchair components to remove or clear prior to transfer

Footrests, the armrest adjacent to the target surface, pelvic seatbelts, chest harnesses, and lateral trunk supports.

Optimal foot placement prior to a stand-pivot transfer

Feet flat on the floor hip-width apart, knees over feet, ankles stabilized, and heels angled toward the destination surface.

Biomechanical importance of forward weight shift before transfers

Shifts the center of mass over the feet and unweights the buttocks to permit standing, partial standing, or pivoting.

Biomechanical effect of posterior pelvic tilt during transfer initiation

Displaces center of mass backward, impeding anterior weight shift and hindering buttock clearance from the seat.

Importance of midline trunk alignment during transfers

Promotes symmetrical weight bearing, enhances stability, and minimizes the risk of losing balance for both client and clinician.

Positioning of a paretic or nonfunctional upper extremity during transfer

Secured in a safe, supported position (such as resting on the client's lap) to prevent traction injuries and shoulder subluxation.

Rationale for instructing clients not to grab the therapist during transfer

Sudden traction or pulling compromises therapist balance and biomechanics, creating a significant fall risk for both individuals.

Scapular protection when rolling a client with hemiplegia

Gently protract the scapula and support the affected arm before rolling to avoid rolling directly onto an unprotected shoulder joint.

Bed mobility sequence for rolling toward the affected side (hemiplegia)

Cradle the weak arm with the intact arm, reach across toward the rolling side, flex knees and hips, and guide the scapula and pelvis into side-lying.

Assisting a client from side-lying to edge-of-bed sitting

Lower feet over the bed edge to act as a counterweight, stabilize the lower extremities, and guide the trunk upward into an erect seated posture.

Facilitating edge-of-bed scooting for a client with stroke or TBI

Elicit alternating lateral weight shifts and guide the unweighted buttock forward until feet rest firmly on the floor.

Facilitating edge-of-bed scooting for an individual with SCI

Support the lower extremities behind the knees, guide legs forward, and establish flat foot placement with neutral ankle alignment.

Primary indications for a stand-pivot transfer

Client possesses sufficient lower-extremity strength and balance to stand and pivot on the feet with appropriate assistance (e.g., hemiparesis or generalized weakness).

Stand-step transfer definition and distinction from stand-pivot

A transfer where the client achieves full upright standing and takes multiple small steps toward the destination rather than pivoting on fixed feet.

Biomechanical vulnerability during a stand-pivot transfer with hemiparesis

Asymmetrical loading forces the intact limb to support weight while the paretic foot and ankle risk external torsion or buckling during pivot.

Therapist positioning during an assisted stand-pivot transfer for hemiparesis

Stand on the client's affected side to stabilize the paretic foot and knee while supporting the trunk or pelvis.

Indications for a bent-pivot (squat-pivot) transfer

Client cannot initiate or maintain full upright standing and requires therapist-assisted pivoting while maintaining flexed knees.

Sequential steps of a bent-pivot transfer

Scoot to edge, place feet flat, align trunk, shift weight forward, use functional arm to push or reach, and pivot across to destination with knees bent.

Clinical rationale for executing a bent-pivot transfer in stages

Allows therapist and client to pause, reposition the feet, and maintain dynamic balance and control throughout the pivot.

Critical upper-extremity precaution during assisted transfers of a paretic limb

Never exert traction on the weak arm or lift under the axilla, as this causes severe traction neuropathy and glenohumeral joint injury.

Primary indication for a sliding-board transfer

Inability to bear functional weight through the lower extremities, utilizing a rigid board to bridge gaps between surfaces without standing.

Correct anatomical placement of a sliding board

Positioned securely beneath the mid-thigh between the ischial tuberosity and knee, spanning firmly between both transfer surfaces.

Client head-hips relationship during a sliding-board transfer

Lean the head and trunk forward and laterally away from the transfer direction to unweight and propel the pelvis toward the destination.

Upper-extremity physical prerequisites for independent sliding-board transfers

Sufficient bilateral upper-extremity strength (especially triceps, latissimus dorsi, and shoulder depressors) to lift or slide the torso.

Indications for utilizing a mechanical lift or multi-person transfer assist

Client is fully dependent, unable to assist safely, or poses a manual handling load that exceeds clinician lifting capacity.

Systematic progression for clinical transfer training

Master simple level transfers (e.g., mat table to wheelchair) before advancing to complex ecological transfers (e.g., toilet, car, uneven surfaces).

A perspective positing that motor behavior self-organizes and emerges from the complex, non-linear interaction among the person, task, and environment.

Heterarchical model of motor control

A control framework wherein movement emerges through cooperation among distributed, interacting subsystems without a single supreme executive center.

Key distinction between hierarchical and heterarchical motor control models

Hierarchical models view motor execution as rigid top-down command; heterarchical models view movement as an emergent product of interacting multi-system subsystems.

Task-oriented approach to motor learning

An occupation-based, client-centered intervention model utilizing real tasks, natural objects, and varied environments to cultivate motor problem-solving.

Biomechanical and sensory advantages of utilizing real objects during motor training
