All questions
Question 1
A COTA is working with an adolescent client with dyspraxia on motor reeducation to improve their ability to tie shoelaces. The client is in the initial (cognitive) stage of learning this new skill.
What type of feedback should the COTA provide to be MOST effective during this stage?
- Summary feedback after five consecutive attempts.
- Bandwidth feedback, intervening only when errors are significant.
- Intermittent feedback on every third or fourth attempt.
- Concurrent and immediate feedback after each step of the process. (correct answer)
Explanation: In the cognitive stage of motor learning, the learner is trying to understand the task. They benefit most from frequent, direct, and immediate feedback (concurrent or terminal) to help them understand errors and correct their performance. As the skill becomes more established, feedback should become less frequent (as in A, B, and C) to encourage internal problem-solving.
Question 2
A COTA is implementing an intervention plan for a client who has moderate left upper extremity (UE) hemiparesis following a CVA. The plan includes constraint-induced movement therapy (CIMT) to improve functional use of the affected UE. During the session, the COTA secures a safety mitt on the client's unaffected right hand.
What is the PRIMARY role of the COTA during the activity portion of this CIMT session?
- To provide passive range of motion to the affected UE to prevent contractures.
- To engage the client in repetitive, task-specific training with the affected UE. (correct answer)
- To modify the long-term goals of the intervention plan based on client progress.
- To document the client's emotional response to having the unaffected hand restrained.
Explanation: The core principle of CIMT is to force the use of the affected extremity through massed, repetitive, task-oriented practice. The COTA's primary role is to implement this by guiding and encouraging the client through these specific activities. A is incorrect because CIMT focuses on active, not passive, movement. C is incorrect as modifying long-term goals is the responsibility of the OTR. D is an important component of documentation but is not the primary therapeutic role during the activity.
Question 3
An intervention plan for a client with left hemiplegia and significant flexor synergy in the upper extremity includes Neuro-Developmental Treatment (NDT) principles. The COTA is preparing to work with the client on reaching for an object.
According to NDT principles, what initial step should the COTA take to prepare the client for this functional reaching task?
- Encourage the client to quickly reach for the object to promote motor learning.
- Apply a hot pack to the spastic muscles to promote relaxation.
- Guide the client to bear weight on the extended left arm while seated. (correct answer)
- Place the client's left hand in a resting hand splint to reduce tone.
Explanation: A key principle of NDT is tone inhibition through techniques like weight-bearing on the affected side. Having the client bear weight on their extended hemiplegic arm provides prolonged proprioceptive input that helps to inhibit flexor synergy and normalize tone, thus preparing the limb for more active, functional movement. A would likely increase synergy. B is a preparatory modality but not a core NDT technique for this purpose. D is a static approach, whereas NDT emphasizes dynamic handling and movement.
Question 4
A COTA is implementing a motor reeducation program for a client with Parkinson's disease who experiences freezing of gait, particularly when initiating walking. The intervention plan includes task-oriented training with external cueing.
Which strategy BEST implements this approach to address the client's freezing of gait?
- Instructing the client to visualize walking smoothly before they begin.
- Placing brightly colored tape strips on the floor and instructing the client to step over them. (correct answer)
- Having the client practice standing up and sitting down ten times.
- Recommending the client obtain a walker with laser light cues from a vendor.
Explanation: Using external visual cues, such as tape strips on the floor, is a well-established task-oriented strategy to help individuals with Parkinson's disease overcome freezing of gait. The visual target provides a focal point that helps bypass the dysfunctional basal ganglia circuits. A is motor imagery, a different technique. C is a strengthening exercise but doesn't directly address gait initiation. D involves recommending equipment, which may be part of the plan, but the COTA's role here is to implement a training strategy directly.
Question 5
A client with Complex Regional Pain Syndrome (CRPS) Type 1 in their right hand is progressing through a graded motor imagery program. The COTA has confirmed the client has mastered the first stage, left/right hand identification. The intervention plan indicates proceeding to the next stage.
What activity should the COTA implement NEXT as part of the graded motor imagery sequence?
- Wrapping the affected hand in a compression garment.
- Beginning mirror therapy exercises.
- Guiding the client through imagined movements of their right hand. (correct answer)
- Initiating gentle, active range of motion of the right wrist.
Explanation: Graded motor imagery follows a specific three-stage sequence: 1) Left/right discrimination, 2) Explicit motor imagery (imagining movements), and 3) Mirror therapy. Since the client has mastered stage one, the COTA's next step is to implement stage two, which involves having the client imagine moving their affected hand without actually moving it. A and D are other potential interventions for CRPS but are not part of the graded motor imagery sequence. B (mirror therapy) is the third and final stage of the program.
Question 6
A COTA is working in an outpatient pediatric clinic with a child who has poor proprioception and motor planning deficits. The OTR's intervention plan includes using sensory-based motor activities to improve body awareness for participation in playground games.
Which activity implemented by the COTA would provide the MOST effective proprioceptive input to support this goal?
- Swinging on a platform swing in a linear direction.
- Playing with therapy putty to improve hand strength.
- Pushing a 'crash cart' filled with weighted balls across the room. (correct answer)
- Identifying different textures with eyes closed.
Explanation: Pushing a weighted cart is a 'heavy work' activity that provides significant proprioceptive input to the muscles and joints. This type of input helps to improve body awareness and motor planning. A provides vestibular input. B provides some proprioceptive input to the hands but not the whole body. D is a tactile discrimination activity.
Question 7
A client with left hemiplegia following a stroke is seated at the edge of the mat. The intervention plan specifies using weight-bearing on the affected upper extremity as a preparatory activity before dressing tasks. The COTA is implementing this part of the plan.
Which method is the MOST appropriate for the COTA to use to facilitate therapeutic weight-bearing?
- Passively move the client's arm through its full range of motion.
- Place a 5-pound cuff weight on the client's wrist.
- Ask the client to hold their arm straight out in front of them for 30 seconds.
- Position the client's affected hand flat on the mat and encourage leaning onto it to reach for an object. (correct answer)
Explanation: This method facilitates active weight-bearing through a closed-chain movement, which provides proprioceptive input, promotes co-contraction of shoulder muscles for stability, and helps normalize tone. It is a functional and effective NDT-based technique. A is passive ROM, not weight-bearing. B adds resistance but does not provide the joint approximation of weight-bearing. C is an open-chain exercise that may be difficult and could increase synergistic patterns.
Question 8
During a constraint-induced movement therapy (CIMT) session, a client with UE hemiparesis becomes visibly frustrated and upset after repeatedly failing to pick up a small peg. The client states, 'This is impossible, I can't do it!'
What is the COTA's BEST immediate response to this situation?
- End the CIMT session for the day to avoid further distress.
- Consult with the OTR to determine if CIMT is still an appropriate intervention.
- Grade the task down by providing a larger, easier-to-grasp object. (correct answer)
- Instruct the client to take a short break and then attempt the same task again.
Explanation: The COTA's role includes grading activities to provide the 'just-right challenge'. When a client is overly frustrated, the task is too difficult. Grading the activity down (e.g., using a larger object) allows the client to experience success, which is motivating and essential for motor learning, while still adhering to the CIMT protocol. A is premature, B is not necessary for an in-the-moment adjustment, and D does not address the core problem that the task is too hard.
Question 9
A client is recovering from a median nerve repair and has developed hypersensitivity in the palm and fingers, making it difficult to hold objects. The intervention plan includes a sensory reeducation program involving a desensitization hierarchy.
Which sequence of textures should the COTA use to implement this desensitization program?
- Sandpaper, then rice, then cotton balls.
- Cotton balls, then rice, then sandpaper. (correct answer)
- Rice, then cotton balls, then sandpaper.
- Sandpaper, then cotton balls, then rice.
Explanation: A desensitization program progresses from the least irritating to the most irritating textures. The typical hierarchy starts with soft textures (cotton balls), moves to medium textures (rice, beans), and finally progresses to rough textures (sandpaper). This gradual exposure helps the nervous system accommodate and normalize its response to stimuli.
Question 10
The intervention plan for a client with sensory deficits following a CVA includes activities to improve stereognosis in their affected hand. The COTA is selecting an activity to implement.
Which activity would be MOST appropriate for the COTA to use to address the goal of improving stereognosis?
- Identifying if a stimulus on the fingertip is sharp or dull.
- Determining if an object placed in the hand is hot or cold.
- Finding a key hidden in a bowl of uncooked pasta without using vision. (correct answer)
- Tracing a letter on the palm of the hand and identifying it.
Explanation: Stereognosis is the ability to identify objects by touch alone, without vision. Having the client find a specific object (key) among other distracting textures (pasta) directly targets this skill. A tests pain/sharp-dull discrimination. B tests temperature sensation. D tests graphesthesia.
Question 11
A COTA is working with a client with hemiplegia on improving sit-to-stand transfers. The intervention plan specifies using handling techniques based on NDT principles to facilitate the movement.
To facilitate an effective anterior weight shift, where are the BEST key points of control for the COTA to place their hands?
- On the client's knees to prevent buckling.
- On the client's shoulders and pelvis. (correct answer)
- Under the client's affected arm to provide support.
- On the client's hands to guide reaching forward.
Explanation: In NDT, key points of control are specific body parts from which movement can be effectively facilitated. For sit-to-stand, hand placement on the shoulders and pelvis allows the COTA to guide the client's center of mass forward over their base of support (the feet), which is the critical component of the transfer. While other placements might provide support, they are less effective for facilitating the overall movement pattern.
Question 12
A client with limited active movement in their hand post-stroke has been successfully using mirror therapy to perform isolated finger flexion and extension. The COTA observes that the client can perform these movements consistently and without pain. The OTR has instructed the COTA to progress the intervention.
What is the MOST appropriate way for the COTA to progress this mirror therapy intervention?
- Increase the duration of the session from 15 to 30 minutes.
- Introduce activities that involve grasping and releasing different objects. (correct answer)
- Remove the mirror and have the client attempt the same movements.
- Add a wrist weight to the unaffected hand for strengthening.
Explanation: Progression in motor reeducation should move from simple, isolated movements toward more complex, functional tasks. Introducing object manipulation (grasping and releasing) is the logical next step to make the therapy more occupation-based and meaningful. A increases duration but not complexity. C removes the therapeutic element of the intervention. D adds strengthening to the unaffected side, which is not the goal of mirror therapy for the affected side.
Question 13
An OTR's intervention plan for a client post-CVA calls for combining Neuro-Developmental Treatment (NDT) principles with a task-oriented approach to improve the client's ability to participate in meal preparation.
How would the COTA BEST implement this combined approach during a sandwich-making activity?
- Focus solely on strengthening the client's grip on the affected side using therapy putty.
- Have the client watch a video of someone making a sandwich before attempting the task.
- Position the client to bear weight on their affected forearm to stabilize a bowl while stirring with the unaffected hand. (correct answer)
- Set up the activity so the client only needs to use their unaffected hand to complete all steps.
Explanation: This option effectively combines both approaches. The NDT principle is applied through weight-bearing on the affected side to normalize tone and provide stability (a preparatory and concurrent technique). This is done within the context of a meaningful, client-centered, task-oriented activity (stirring ingredients for a sandwich). A is not a task-oriented approach. B is a form of motor imagery, not NDT. D promotes learned non-use and does not incorporate the affected side.
Question 14
A client recovering from a peripheral nerve injury has absent protective sensation in their hand but is beginning to regain some motor function. The intervention plan focuses on motor reeducation while ensuring safety.
When implementing an activity that involves manipulating small objects, what is the MOST important instruction the COTA should provide to the client?
- To use visual guidance to monitor hand position and prevent injury. (correct answer)
- To apply as much force as possible to improve grip strength.
- To move the hand as quickly as possible to stimulate nerve regeneration.
- To soak the hand in warm water before the activity to increase blood flow.
Explanation: Without protective sensation, the client is at high risk for injury (e.g., cuts, burns, applying too much pressure). The COTA must teach the client to use vision as a compensatory strategy to monitor their hand during tasks. This is a critical component of sensory reeducation for safety. B and C could easily lead to injury. D is a preparatory method but does not address safety during the activity itself and could be dangerous if the water is too hot and the client cannot feel it.
Question 15
A COTA is re-evaluating a client's progress in motor learning for donning a shirt. The client is in the associative stage of learning, where they can perform the basic steps but still make errors. The intervention plan calls for using a practice schedule that promotes skill retention and generalization.
Which practice schedule should the COTA implement at this stage?
- Blocked practice, having the client don the same shirt 10 times in a row.
- Random practice, alternating between donning a shirt, pants, and socks. (correct answer)
- Massed practice, concentrating all therapy time for the week into one long session.
- Mental practice, having the client visualize the steps without physical practice.
Explanation: In the associative stage of motor learning, random practice (practicing multiple related tasks in a varied order) is more effective than blocked practice for promoting long-term retention and the ability to generalize the skill to different contexts. Blocked practice (A) is better for the initial, cognitive stage of learning. Massed practice (C) refers to the timing of sessions, not the structure within them. Mental practice (D) is a useful adjunct but not a substitute for physical practice at this stage.
Question 16
A COTA is working with a client recovering from a TBI who has deficits in bilateral integration, affecting their ability to perform self-care tasks. The intervention plan includes activities to reeducate this motor skill.
Which activity would be MOST effective for the COTA to implement to promote bilateral integration?
- Sorting laundry by color with one hand.
- Carrying a grocery basket with one arm.
- Drying their back with a towel using both hands. (correct answer)
- Brushing their teeth with their dominant hand.
Explanation: Drying one's back with a towel requires the coordinated use of both hands working together in a reciprocal motion, which directly targets bilateral integration. The other options are unilateral activities (A, B, D) and would not effectively address the client's specific deficit in using both sides of the body together.
Question 17
A COTA is working with a client who has ataxic movements following a traumatic brain injury (TBI). The intervention plan, developed by the OTR, includes using proprioceptive neuromuscular facilitation (PNF) techniques to improve controlled movement for ADLs.
To improve the client's ability to bring a cup to their mouth, which PNF pattern should the COTA facilitate?
- D1 flexion of the upper extremity. (correct answer)
- D1 extension of the upper extremity.
- D2 flexion of the upper extremity.
- D2 extension of the upper extremity.
Explanation: The D1 flexion pattern for the UE involves shoulder flexion, adduction, and external rotation, which functionally mimics the movement of bringing the hand to the mouth for self-feeding. The COTA would implement this pattern to reeducate the desired motor sequence. The other patterns correspond to different functional movements (e.g., D1 extension is pushing down and away, D2 flexion is combing hair on the opposite side, D2 extension is putting on a seatbelt).
Question 18
A client is recovering from a right below-elbow amputation and is experiencing phantom limb pain. The OTR has included mirror therapy in the intervention plan to address this. The COTA is preparing to implement the first session.
How should the COTA set up the environment and instruct the client to begin the mirror therapy session?
- Place the mirror between the legs and have the client imagine the amputated limb is moving.
- Position the mirror to reflect the intact left arm and instruct the client to watch the reflection while moving the intact arm. (correct answer)
- Have the client touch the residual limb with the intact hand while looking in the mirror.
- Ask the client to perform bilateral movements while focusing on the sensation in the residual limb.
Explanation: The correct setup for mirror therapy involves placing the mirror midsagittally so that the reflection of the intact limb appears superimposed over the perceived location of the amputated limb. The client then moves the intact limb while watching the reflection, which creates a visual illusion of the phantom limb moving without pain. A is incorrect positioning. C and D do not utilize the principle of visual feedback that is central to mirror therapy.
Question 19
A client is scheduled to begin an intervention session that includes constraint-induced movement therapy (CIMT) for their left UE. Upon greeting the client, the COTA notices new, significant edema and redness in the client's affected hand and the client reports a new 'burning' pain.
What is the COTA's MOST appropriate immediate action?
- Proceed with the CIMT session but use lighter and less repetitive tasks.
- Provide retrograde massage to the hand before applying the constraint.
- Document the observations and report them to the OTR at the end of the day.
- Withhold the CIMT intervention and immediately notify the supervising OTR. (correct answer)
Explanation: New and significant edema, redness, and burning pain are potential signs of a serious underlying medical issue, such as a deep vein thrombosis (DVT) or cellulitis, which would be contraindications for CIMT. The COTA's primary responsibility is client safety. Therefore, they must withhold the intervention and immediately consult with the OTR, who can then determine the appropriate course of action, which may include referral to a physician.
