Effect of Decreased Skeletal Muscle Index and Hand Grip Strength on Functional Recovery in Subacute Ambulatory Stroke Patients
Jin Gee Park, Kyeong Woo Lee, Sang Beom Kim, Jong Hwa Lee, Young Hwan Kim
Ann Rehabil Med 2019;43(5):535-543.   Published online October 31, 2019
DOI: https://doi.org/10.5535/arm.2019.43.5.535
Objective
To investigate the effect of decreased Skeletal Muscle Index (SMI) and hand grip strength on functional recovery in subacute ambulatory stroke patients.
Methods
Subacute stroke patients who were referred to the rehabilitation center were recruited. Decreased SMI and hand grip strength were diagnosed according to the Asian Working Group on Sarcopenia. Diagnostic criteria were decreased SMI and decreased unaffected hand grip strength. SMI was measured by bioelectrical impedance analysis. Unaffected hand grip strength was measured with a hand dynamometer. Patients were divided into two groups, decreased group (DG) and not-decreased group (NDG), according to the presence of decreased SMI and hand grip strength. Both groups received conventional stroke rehabilitation for 3 weeks. All patients were evaluated at the baseline and at 3 weeks after treatment. Functional status was evaluated with 4-meter walk test (4MWT), 6-minute walk test (6MWT), Timed Up and Go test (TUG), and Modified Barthel Index (MBI).
Results
Both groups showed improvement in 4MWT, TUG, and MBI. NDG showed improvement in 6MWT. Comparing improvements between the two groups, NDG showed more improvement in 6MWT and TUG than DG.
Conclusion
The presence of decreased SMI and hand grip strength had negative effects on functional recovery in subacute ambulatory stroke patients.

Case Report

Subacute Combined Degeneration Caused by Nitrous Oxide Intoxication: A Report of Two Cases
Cheol Choi, Taehee Kim, Ki Deok Park, Oh Kyung Lim, Ju Kang Lee
Ann Rehabil Med 2019;43(4):530-534.   Published online August 31, 2019
DOI: https://doi.org/10.5535/arm.2019.43.4.530
We report two cases of subacute combined degeneration (SCD) caused by nitrous oxide (N2O) gas intoxication, which is rarely reported in Korea. Two patients recreationally inhaled N2O gas daily for several months. They presented with paresthesia of limbs, voiding difficulty, and gait disturbance. The initial vitamin B12 levels were normal or decreased, but homocysteine levels of the two patients were increased. Magnetic resonance imaging of the cervical spine showed T2-weighted hyperintensity in the bilateral dorsal columns of the cervical spinal cord. Electromyography and somatosensory evoked potential tests for both patients suggested posterior column lesion of the spinal cord combined with sensorimotor polyneuropathy. According to these findings, we concluded that the two patients had SCD. The patient’s symptoms partially improved after cessation of N2O gas inhalation and the receiving of vitamin B12 supplementation therapy. As the incidence of recreational N2O gas inhalation is increasing in Korea, physicians must be alert to the N2O induced SCD in patients presenting with progressive myelopathy.

Effect of Constraint-Induced Movement Therapy and Mirror Therapy for Patients With Subacute Stroke
Jin A Yoon, Bon Il Koo, Myung Jun Shin, Yong Beom Shin, Hyun-Yoon Ko, Yong-Il Shin
Ann Rehabil Med 2014;38(4):458-466.   Published online August 28, 2014
DOI: https://doi.org/10.5535/arm.2014.38.4.458
Objective

To evaluate the effectiveness of constraint-induced movement therapy (CIMT) and combined mirror therapy for inpatient rehabilitation of the patients with subacute stroke.

Methods

Twenty-six patients with subacute stroke were enrolled and randomly divided into three groups: CIMT combined with mirror therapy group, CIMT only group, and control group. Two weeks of CIMT for 6 hours a day with or without mirror therapy for 30 minutes a day were performed under supervision. All groups received conventional occupational therapy for 40 minutes a day for the same period. The CIMT only group and control group also received additional self-exercise to substitute for mirror therapy. The box and block test, 9-hole Pegboard test, grip strength, Brunnstrom stage, Wolf motor function test, Fugl-Meyer assessment, and the Korean version of Modified Barthel Index were performed prior to and two weeks after the treatment.

Results

After two weeks of treatment, the CIMT groups with and without mirror therapy showed higher improvement (p<0.05) than the control group, in most of functional assessments for hemiplegic upper extremity. The CIMT combined with mirror therapy group showed higher improvement than CIMT only group in box and block test, 9-hole Pegboard test, and grip strength, which represent fine motor functions of the upper extremity.

Conclusion

The short-term CIMT combined with mirror therapy group showed more improvement compared to CIMT only group and control group, in the fine motor functions of hemiplegic upper extremity for the patients with subacute stroke.

The Effect of Prolonged Inpatient Rehabilitation Therapy in Subacute Stroke Patients
Jong Hwa Lee, Sang Beom Kim, Kyeong Woo Lee, Ji Yeong Lee
Ann Rehabil Med 2012;36(1):16-21.   Published online February 29, 2012
DOI: https://doi.org/10.5535/arm.2012.36.1.16
Objective

To evaluate the effect of prolonged inpatient rehabilitation therapy in subacute stroke patients.

Method

We enrolled 52 subacute stroke patients who had received 3 months of inpatient rehabilitation therapy. Thirty stroke patients received additional inpatient rehabilitation therapy for 3 months and 22 control patients received only home-based care. The evaluation was measured at 3 and at 6 months after stroke occurrence. Functional improvement was measured using the modified motor assessment scale (MMAS), the timed up and go test (TUG), the 10-meter walking time (10 mWT), the Berg balance scale (BBS) and the Korean-modified Barthel index (K-MBI). The health-related quality of life was evaluated using the medical outcome study, 36-item short form survey (SF-36).

Results

In the experimental group, significant improvements were observed for all parameters at 6 months (p<0.05). However, significant improvements were observed only in MMAS, BBS, and K-MBI at 6 months in the Control group (p<0.05). In comparing the 2 groups, significant difference were observed in all parameters (p<0.05) except 10 meter walking time (p=0.73). The improvement in SF-36 was meaningfully higher in experimental group compared to control group.

Conclusion

This study demonstrates that subacute stroke patients can achieve functional improvements and an enhanced quality of life through prolonged inpatient rehabilitation therapy.

Case Reports
Subacute Progressive Ascending Myelopathy: A case report.
Yoo, Ji Sung , Sung, Duk Hyun
J Korean Acad Rehabil Med 2010;34(5):595-598.
Subacute progressive ascending myelopathy is a rare condition complicating spinal cord injury, unrelated to mechanical compression, instability, hemorrhage or syrinx formation. Clinically, ascending neurological deficit may extend at least two segments above the level established at the initial insult within the first 3 weeks of the initial spinal cord insult. MR imaging characteristically demonstrates cord changes ascending at least four vertebral levels above the initial injury site. The development of progressive myelopathy is a dreaded complication of spinal cord injury and is not misunderstood for post-op complication. We describe a case of a 29-year-old male patient who suffered a falling down accident. He initially presented with a T12 vertebral fracture with associated cord compression and signal changes in the spinal cord. During the subsequent 3 weeks, he developed progressive sensory changes with cord signal abnormalities on magnetic resonance imaging extending above from the injury site.

Two Cases Report of Subacute Combined Degeneration in Association with Folate Deficiency.
Ko, Young Jin , Kim, Hye Won , Lee, Jung Soo , Choi, Soo Jung , Shin, Ji Nam
J Korean Acad Rehabil Med 1999;23(2):430-433.

Subacute combined degeneration is the clinical syndrome associated with vitamin B12 deficiency and characterized by usually symmetrical weakness and progressively worsening of, and abnormal sensations of the legs, arms, trunk, or other area, mental abnormalities, and vision difficulties. Subacute combined degeneration primarily affects the spinal cord, but it also includes damage to the brain, the nerves of the eye, and the peripheral (body) nerves. In this study, we report two patients with subacute combined degeneration of the cord in association with folate deficiency. Subacute combined degeneration of the spinal cord and optic atrophy occurred only in the patients with vitamin B12 deficiency. However, diet-induced folic acid deficiency and subacute combined degeneration of the spinal cord which improved significantly after treatment with folic acid has been recorded.

Subacute Combined Degeneration of the Spinal Cord in Association with Pernicious Anemia: A case report.
Park, Noh Kyoung , Kim, Dong Soo , Lee, Jong Hyun , You, Jang Hun , Cho, In Han
J Korean Acad Rehabil Med 2005;29(6):678-680.
Subacute combined degeneration is a disease of spinal cord involving the posterior and lateral columns due to vitamin B12 deficiency. We experienced a 56-year-old man suffering subacute combined degeneration, characterised by dysesthesia and disturbance of deep sensation such as position sense,proprioception and vibration sense in the lower extremities, and ataxic gait. We reported one patient with subacute combined degeneration of the cord in association with pernicious anemia resulting from inactivation of intrinsic factor by it's antibodies.

J Korean Acad Rehabil Med 2009;33(6):711-714.
Vitamin B12 deficiency can cause myelopathy of subacute combined degeneration of lateral and dorsal column in spinal cord. When combined with compressive myelopathy, symptoms and signs of vitamin B12 deficient myelopathy could be masked. We experienced a case of forty-one year old man suffered from gait disturbance and decreased proprioception. Initially surgeons concluded his weakness resulted from myelopathy by C5-6 centrally herniated disk based on MRI and surgical decompression was performed. Gait disturbance slightly improved but decreased proprioception did not improve. Vitamin B12 deficiency was found and high signal intensity lesions were found in dorsal and lateral spinal column with review of pre-op MRI. After administration with vitamin B12 supplements, weakness and sensation of proprioception improved and follow-up MRI showed decreased signal intensity. We concluded the cause of his symptoms was combination of compressive myelopathy and vitamin B12 deficient myelopathy. (J Korean Acad Rehab Med 2009; 33: 711-714)
