A 42 year-old woman presents with difficulty walking and numbness/tingling. She underwent gastric bypass surgery 10 years ago and has not been compliant with diet instructions since then. She lost 200 pounds with her surgery. Her examination shows sensory loss to vibration and proprioception in a stocking glove distribution with hyperreflexia in her bilateral upper extremities and patella (with crossed adductors). Her ankle jerks are absent. Strength examination shows mild weakness in bilateral dorsiflexion, plantar flexion, toe flexion and toe extension. Gait has both steppage and some spasticity observed. Cerebellar examination is normal. Some of her laboratory studies are pending. However, her hemoglobin is slightly low at 10.4 grams/deciliter with an MCV of 118. Her methylmalonic acid is quite elevated at 1000. MRI of the cervical spine shows non-enhancing hyperintensities in the posterior and lateral spinal cord. Which deficiency is likely etiology of the patients’ symptoms, examination, available laboratory test results and imaging?

- Refer to the electromyogram (EMG). Select the correct statements. motor unit C motor unit motor unit A. EMG 1 sec force Force production is modulated by recruitment of motor units. A motor unit is composed of a few muscle fibers innervated by an upper motor neuron. According to the Henneman's size principle, the large motor units will be recruited followed by the small motor units. Small motor units have small cell body. Large motor units have many fast twitch Type I muscle fibers. Small motor units have lower threshold and 'high' excitability. Large motor units produce high tetanic tension and contraction speed.arrow_forwarda 20 yrs old man with a neck flexion- extension (whiplash) injury is treated at your outpatient setting two weeks after a motor vehicle accident. what questions would the PT ask concerning his pain? list at least three.arrow_forwardA 45-year-old woman has sustained a fracture of her right distal tibia and is put in a cast by an orthopedist who wants her to receive physical therapy.

- Carolyn is a 36-year-old mother of three young children. She had an accident while skiing. After 4 months, she is still experiencing pain in her right knee and is walking with a limp. Carolyn visits the orthopedic physician and is told she needs an arthroscopic examination. While doing the arthroscopy, the physician also removes scar tissue in her knee joint. The follow-up care requires intensive physical therapy.1. What leg muscles were affected by Carolyn’s injury?2. Immediately after Carolyn’s injury, what type of treatment might be started?3.

- A patient demonstrates 0 (absent) DTR of the right triceps brachii, paresthesia over the right third digit and 3/5 strength during resisted elbow extension and wrist flexion testing. What is the most likely diagnosis? What are common types of treatment for this condition?arrow_forwardMatch the term with the correct description. these are the terms: Anterior longitudinal ligament (ALL) Posterior longitudinal ligament (PLL) Ligamentum flava Ligamentum nuchae these are the descriptions: This is a large ligament located between the posterior muscles of C1 to C6-C7 spinous processes. This ligament becomes part of the supraspinous ligament at C7. It limits hyperflexion of the neck. Supraspinous ligament This is a thick ligament connecting the spinous processes of C7 down to the L3 or L4 vertebrae. It joins other ligaments to limit flexion of the spinal column. This ligament is attached to the posterior surface of the vertebrae body and the intervertebral discs in the spinal canal. It starts from C2 and extends downward to the sacrum. It prevents hyperflexion. It also supports the spinal column. Located within the spinal canal, it is found on the posterior bodies of the vertebrae. It starts at C2 and moves downward to the sacrum. It prevents hyperflexion. It also supports…arrow_forward46.
