This set of Clinical Science Multiple Choice Questions & Answers (MCQs) focuses on “Rehabilitative Devices”.
1. Rehabilitative devices are used for cases involving :
i. Trauma ii. Palsy iii. Geriatric Population iv. Cancer Patients v. Sports injury vi. Fever vii. Illiterate people viii. Post Surgery ix. Amputation x. Cardiac Arrest
a) i, ii, iii, v, viii, ix
b) i, ii, ix, x
c) iii, vi, vii, ix
d) i, v, vi, vii
Explanation: Rehabilitation is a process in which the normal functioning of the body is restored. It is a process done for injury recovery, re educating and regaining the strength of the body. It also included care and precaution to be taken after such procedures.
2. After a simple fracture, what is the recommended period of bed rest?
a) 1 week
b) 2 weeks
c) 1 month
d) 2 months
Explanation: After a person has suffered from a fracture, it is recommended to rest for at least 2 weeks. In this period, the injury should ideally have no movement at all. After 2 weeks, simple weight bearing activities are done and eventually, normal functioning is recovered. Normally, it takes well over 2 months for even a simple fracture to heal completely but simple activities with the help of assistive devices can be started after 2 weeks of rest.
3. Cerebral Palsy can be detected by which gait pattern?
a) Waddling gait
b) Stomping gait
c) Scissoring Gait
d) Swayback Gait
Explanation: Cerebral Palsy is am often found the problem with young children. It is caused due to various factors, injury to the brain being the most prominent one. If a motor neuron has a lesion, then the signals that are sent to the legs do not reach properly and the child walks with a scissoring gait. In this walking pattern, the feet don’t fall straight but they fall in front of each other. Thus, a criss – cross motion happens.
4. Why should wheelchairs be avoided by young population?
a) It damages the neural system of the body
b) It causes inflammation in the GI track
c) It causes low blood pressure
d) It damages the bones and skeletal muscles
Explanation: The bones and the skeletal muscles function well when pressure is applied to them. It allows for better absorption of nutrients. When a young person uses a wheel chair for a long time, their bones and muscles stop absorbing the nutrients and the body becomes weak. Long use of wheelchairs by any population can cause other problems as well as the pooling of blood, pressure sores etc.
5. Match the following devices with the kind of devices:
|Device||Type of Device|
|Prosthetic Leg (PL)||Assisitive Device (AD)|
|Calipers (C)||Rehabilitative Device (RD)|
|Knee Brace (KB)||Substitutive Device (SD)|
a) PL – SD, C – RD, KB – AD
b) PL – AD, C – SD, KB – RD
c) PL – SD, C – AD, KB – RD
d) PL – AD, C – RD, KB – SD
Explanation: A prosthetic leg is used in cases of amputation due to trauma or disease (eg polio – the diseases part of the leg is amputated and then a prosthetic leg is used) or if the person is naturally without the limb. Since it susbtitues the original leg, it is a susbtitutive device. Calipers are used by people to help in movement, either in old age or injury or some genetic problem. A knee brace is worn to support an injury or to mitigate the pain so it is a rebalitative device.
6. What kind of assistive device does a person hard of hearing use?
a) cochlear implant
b) hearing aid
c) device giving electrical impulses to the ear
d) surgical methods
Explanation: A hearing aid amplifies the sound and lets a person hear better. A person who is hard of hearing normally has a damaged tympanic membrane which is unable to amplify the sound waves and send it to the ear. In such cases, a hearing aid which amplifies the sound waves is used. These amplified sound waves reach the cochlea of the ear where the sensory hair convert the sounds into electrical impulses and the sound is processed.
7. Can glasses be taken as assistive devices?
Explanation: An assistive device is such that it helps a person with a disability. A person wearing glasses has the disability of weak eyes so to improve the vision, they wear glasses. Thus, glasses do not completely correct the vision as once they are removed, the vision of the person will be bad again. So, they can be called assistive devices.
8. To help a child with scissoring gait, what should not be done?
a) releasing a tendon surgically
b) tying two pillows on the inner side of the leg and having the child walk
c) surgical amputation of legs
d) making the child walk with a mild obstruction between the two legs
Explanation: Scissoring gait is one way cerebral palsy is expressed. In this gait, the child does not walk straight but criss-crosses the leg i.e. putting the right leg in front of the left leg while walking. To correct this, an obstruction between the legs is given like tying pillows or balls or making the child walk with a low wall in between. With this, the brain is slowly trained to walk straight.
9. What can be done for a person suffering from a foot drop palsy?
a) wear the brace in the form of socks or stiff shoes
b) surgical amputation
c) releasing a tendon
d) use calipers
Explanation: Foot drop palsy happens when a person’s ankle muscles have lost strength or the tendon has been severely damaged. When a person suffering from foot drop palsy is walking, on raising their feet, the foot drops down completely. This can cause harm and to reduce this, a brace which holds the foot close to the calf at the normal position should be worn.
10. Which of the following happens in hemiplegic gait?
a) circumduction of the legs
b) swayback posture
c) stomping of the foot
d) swinging of the arms
Explanation: In a hemiplegic gait, the muscles of the calves have lost strength but the thigh muscles are strong enough. Thus, to move the body, instead of lifting the feet, the person uses their thigh muscles to circumduct the leg and step forward.
11. In cases of neuromuscular injury, which method is used to rehabilitate them?
a) Transcutaneus Electrical Nerve Stimulation
b) Heat Therapy
Explanation: Transcutaneus Electrical Nerve Stimulation (TENS) uses electrodes to stimulate the nerve and the muscles. It generates mild electrical impulses and these impulses help move the muscles. It is a way to rehabilitate the injured part of the body and also to check how much muscle activity is left possible.
12. In Bells Palsy, the face muscles get paralyzed. To protect the eye from harm, what all can be done?
i) Use eye patch ii) Stay in a dark Room iii) Use eye drops iv) Rub the eyes v) Massage the eye area vi) Eat Vitamin A
a) i, ii, iii, iv, v, vi
b) i, iii, v
c) ii, iii, vi
d) iii, v, vi
Explanation: In Bell’s Palsy, a person’s face muscles get paralyzed. The condition can get better within months or may last a long time. The reason for this paralysis is inflammation or impingement of the cranial nerve that supplies to the face. Thus, the movements of the face, including blinking and producing tears is disturbed causing the eye to remain open, become dry and vulnerable to infections. In such cases, it is important to cover the eye and keep it moist. Thus an eye patch and eye drops are a feasible option. Massaging the eye area will enhance the blood flow and relieve some tension in the paralyzed muscles.
