- Which activity is MOST appropriate for the COTA to use to elicit a protective extension forward response?
Answer: Have the child sit on a small bench while the COTA gently nudges them forward from the shoulders.
A gentle but quick forward nudge while the child is seated will shift their center of gravity and should elicit an automatic forward protective response, where the child puts their hands out in front to 'catch' themselves. This directly and safely targets the desired reaction. Rocking backward elicits a backward response. Walking on a line targets dynamic balance, not protective extension. Playing with blocks is a fine motor task.
- Which seating device would provide the necessary support to facilitate an upright posture while still allowing for some active participation?
Answer: A floor sitter with lateral trunk supports and a chest strap.
A floor sitter with lateral supports and a chest strap provides external stability for the trunk and pelvis, allowing the child to maintain an upright posture against gravity. This frees up their hands for play and visual exploration while still requiring them to use their head and neck muscles actively. A beanbag chair or recliner provides poor postural support. A standard high chair may not provide enough specific trunk support for a child with significant hypotonia.
- What is the COTA's primary therapeutic action to facilitate postural extension and righting reactions?
Answer: Gently and slowly move the swing in a linear direction.
Moving the swing gently and slowly provides controlled vestibular input, which prompts the child to make active postural adjustments, such as lifting their head and upper trunk against gravity (postural extension) to maintain their position. This is a core technique for improving postural control. Asking the OTR for a re-evaluation is not an intervention. Pushing the swing high is likely to be overstimulating and frightening for a child with gravitational insecurity. Adding pillows reduces the need for the child to actively engage their muscles for stability.
- What is the MOST effective technique for the COTA to implement to improve the client's postural stability during this task?
Answer: Instruct the client to sit on the edge of the bed with a wide base of support.
Having the client sit on a stable surface like the edge of a bed with feet flat on the floor provides a larger, more stable base of support. This minimizes the balance challenges associated with standing and reduces the risk of backward falls (retropulsion), allowing the client to focus on the dressing task. Leaning against a wall is less stable than sitting. Providing adaptive equipment is a valid compensatory strategy but does not address improving the client's postural stability during the task itself. Marching in place is a good warm-up but does not provide the postural support needed during the actual dressing activity.
- Which activity would be MOST appropriate for the COTA to implement to meet this goal?
Answer: Having the client stand and reach for cones placed on their right side.
Reaching for cones placed on the affected (right) side requires the client to actively shift their weight onto the paretic leg, directly addressing the goal of improving dynamic postural control and weight-bearing on that side. Passive range of motion is a preparatory technique and does not involve active postural control. Seated activities do not adequately challenge standing balance. Treadmill walking focuses more on gait pattern and endurance rather than the specific component of controlled, dynamic weight-shifting.
- What is the BEST way for the COTA to modify the environment to facilitate improved postural control?
Answer: Place a high stool behind the client for them to feel without sitting down.
Placing a stool directly behind the client provides a sense of security and a 'safety net' without them having to actively use it for support. This psychological reassurance can decrease their fear of falling, encouraging them to let go of the counter and use more active postural control. Simply telling them to let go is not therapeutic. Seating them changes the task and doesn't address standing balance. A walker encourages continued reliance on an external support.
- What instruction BEST reflects correct body mechanics to protect the client's back?
Answer: Perform a golfer's lift by hinging at the hips while extending one leg back.
A golfer's lift is an ideal technique for picking up a light object from a low surface. It involves hinging at the hips while maintaining a neutral spine, which minimizes strain on the lumbar vertebrae. Bending at the waist, twisting, and crawling are all biomechanically inefficient or potentially harmful strategies for this specific task.
- What is the MOST effective verbal cue the COTA can provide to facilitate a more stable, forward weight shift?
Answer: "Bring your belly button toward the sink."
The cue "Bring your belly button toward the sink" provides a concrete, external focus that encourages an anterior weight shift and pelvic tilt, moving the client's center of mass forward over their base of support. This is an effective way to counteract the posterior weight shift. Telling a client not to be scared is not a functional cue. Locking the knees is a poor compensatory strategy that reduces stability. Holding on promotes dependency rather than facilitating active postural control.
- What is the COTA's MOST appropriate immediate response?
Answer: Modify the task by having the client sit on a high stool at the counter.
Modifying the activity to allow the client to sit on a high stool is the best response. It addresses the immediate safety concern related to postural instability and fatigue while still allowing the client to continue with the meaningful occupation of meal preparation, which aligns with the principles of energy conservation. Pushing through fatigue is contraindicated for MS. Stopping the session is an option, but modifying first is preferred if possible. Switching to an unrelated task abandons the client's goal for the session.
- To appropriately grade this activity UP to further challenge the client's dynamic balance, what should the COTA do NEXT?
Answer: Have the client stir while standing on a foam pad.
Standing on a foam pad creates an unstable surface, which challenges the client's proprioceptive and vestibular systems, thereby increasing the demand on their dynamic balance control. This is an appropriate next step in grading the activity. Sitting on a stool grades the activity down. Using a reacher is a compensatory strategy, not a remedial one for balance. Closing the eyes would be too significant of a challenge at this stage and should only be introduced after the client masters less demanding balance tasks.
- What is the MOST relevant activity for the COTA to introduce to integrate postural control into a meaningful occupation?
Answer: Have the client don a shirt while maintaining balance.
Integrating an ADL task like pulling a shirt on over the head challenges the client's sitting balance in a dynamic and functional way. This is the unique contribution of occupational therapy—linking an underlying skill (postural control) to a meaningful occupation. Timing static sitting and measuring ROM are forms of assessment, not intervention in this context. Providing tactile cues is a technique used during the activity, but the activity itself is the key intervention.
- Which group activity would be MOST effective for addressing this goal?
Answer: Practicing slow, controlled Tai Chi movements.
Tai Chi involves slow, deliberate weight shifting, rotational movements of the trunk, and coordination of the extremities, all of which are excellent for improving dynamic balance and postural control in a controlled, safe manner. Seated exercises and activities do not adequately challenge standing balance. A handout provides education but is not an active intervention for improving physical balance skills.
- Which activity BEST aligns with the implementation of a habituation exercise program?
Answer: Guiding the client through repeated, controlled head movements that elicit mild symptoms.
The principle of habituation is to reduce sensitivity to a stimulus through repeated, controlled exposure. Therefore, the COTA would guide the client through specific movements (like head turns or nods) that bring on mild, tolerable levels of dizziness. Over time, the nervous system adapts, and the dizzy response is reduced. Avoidance strategies, deep pressure, and assistive devices are compensatory and do not address the underlying vestibular sensitivity through habituation.
- Which action should the COTA take to BEST facilitate a more upright and functional sitting posture?
Answer: Place a foam wedge cushion on the chair with the higher end at the back.
Placing a wedge cushion with the higher end at the back promotes an anterior pelvic tilt, which helps the child maintain a more extended spine and an upright posture for tabletop tasks. This directly addresses the observed postural problem. A lap tray supports the upper extremities but doesn't correct the pelvic and trunk posture. A therapy ball is a dynamic surface that may be too challenging for a child with low tone who needs stability. A weighted vest provides proprioceptive input but does not directly facilitate postural alignment.
- Which intervention should the COTA implement FIRST to facilitate symmetrical posture?
Answer: Have the client stand facing a mirror while trying to visually align their shoulders and hips.
Using a mirror provides immediate visual feedback, allowing the client to see their own posture and make active corrections to achieve a more symmetrical stance. This is a crucial first step in re-establishing body scheme and facilitating equal weight-bearing before progressing to more dynamic tasks. Walking is too advanced. Stepping with the intact limb encourages weight-bearing on that side only. Seated tasks do not address standing posture.
- Which intervention setup would be MOST effective for this purpose?
Answer: Standing on a thick foam mat while reaching for objects.
Standing on an unstable surface like a foam mat reduces reliable input from joint receptors in the feet and ankles, forcing the client to rely more on their vestibular and visual systems to maintain balance. Adding a reaching task makes it a dynamic activity, which directly addresses the goal. Walking on a level floor provides minimal challenge. Sit-to-stand is a good functional activity but does not specifically target the proprioceptive challenge. Bouncing on a ball provides vestibular input but in a supported sitting position.
- Which activity should the COTA introduce as the NEXT step to safely progress the client toward the goal?
Answer: Practice stooping to pick up beanbags from the seat of a standard-height chair.
Picking up items from a chair seat is a way to grade the activity. It mimics the motion of picking something from the floor but requires less range of motion and a smaller shift in the center of gravity, making it a safer and more achievable next step. Progressing directly to the floor is too challenging. Tandem standing is a static balance task and does not directly practice the dynamic control needed for stooping. Using a walker is a compensatory approach and does not facilitate the development of independent balance control for the task.
- What is the BEST initial strategy for the COTA to implement to help the child succeed with this task?
Answer: Instruct the child to put on their pants while sitting on a chair or the floor.
The best initial strategy is to grade the task down by reducing the balance requirements. Having the child sit removes the need to balance on one leg, allowing them to focus on the motor planning and coordination aspects of the dressing task. This promotes success and reduces frustration. Practicing single-leg standing is a remedial exercise but is decontextualized. Leaning against a wall is a good next step after sitting, but not the initial strategy. Using an elastic waistband modifies the pants but not the postural demands of the task.
- Which activity would be MOST appropriate for the COTA to implement to target the goal of core strengthening for postural support?
Answer: Performing a bird-dog exercise (quadruped opposite arm/leg lifts).
The bird-dog exercise requires co-contraction of the deep abdominal and back extensor muscles to maintain a neutral spine while the extremities are moving. This directly targets the core stability needed for postural support. Hamstring stretching addresses flexibility, not core strength. Bicycling is primarily a cardiovascular and lower extremity strengthening activity. Squeezing a stress ball is for grip strength.
- Which handling technique should the COTA use to BEST elicit the desired response?
Answer: Gently roll the ball forward, so the child's upper body moves toward the floor.
Gently rolling the ball forward causes the child's center of gravity to shift, prompting a protective response to lift the head and chest against gravity. This active movement strengthens trunk and neck extensors and facilitates the desired postural extension. Rolling the ball backward facilitates flexion. Rolling side-to-side facilitates lateral righting, not extension. Reaching for toys on the floor from this position would also facilitate flexion.
