Clinical Outcomes of Conservative Treatment and Arthroscopic Repair of Rotator Cuff Tears: A Retrospective Observational Study

OBJECTIVE: To compare the clinical outcomes following conservative treatment and arthroscopic repair in patients with a rotator cuff tear. METHODS: In this retrospective study, patients aged >50 years with a symptomatic rotator cuff tear were reviewed. The rotator cuff tendons were evaluated using ultrasonography, shoulder magnetic resonance imaging or MR arthrography, and the patients with either a high-grade partial-thickness or small-to-medium-sized (≤3 cm) full-thickness tear were included in this study. The primary outcome measures were a pain assessment score and range of motion (ROM) at 1-year follow-up. The secondary outcomes were the rate of tear progression or retear along with the rate of symptom aggravation after the treatments. RESULTS: A total of 357 patients were enrolled, including 183 patients that received conservative treatment and 174 patients who received an arthroscopic repair. The pain assessment score (p50 years old with a less than medium-sized rotator cuff tear in a 1-year follow-up period. Further study is warranted to find the optimal combination of conservative treatment for a symptomatic rotator cuff tear.

Retrospective Assessment of the Implementation of Critical Pathway in Stroke Patients in a Single University Hospital

OBJECTIVE: To evaluate the effects of the implementation of critical pathway (CP) in stroke patients treated at a single university hospital. METHODS: A retrospective medical review collected data from 497 patients who had suffered acute stroke in the rehabilitation center. Stroke outcomes were compared between before and after the implementation of CP based on factors including demographic factors, stroke characteristics, pre-existing medical conditions, medical complications, functional states, and length of stay (LOS). RESULTS: After the implementation of CP, the patients showed significantly higher stage for upper proximal (p=0.008) and lower extremity (p=0.001) on Brunnstrom stage and significantly lower scores for modified Rankin Scale (p=0.003) at transfer. For those with pre-existing medical conditions, there were significantly increased osteoarthritis (p=0.002) and valvular heart disease (p=0.011). Regarding medical complications during acute inpatient rehabilitation, there were significantly decreased shoulder pain (p=0.001) and dysphagia (p=0.017), and significantly increased gastrointestinal symptoms (p=0.001). Functional gain and efficiency of stroke patients during rehabilitation center hospitalization did not significantly change after implementation of CP. But, shorter LOS of total hospitalization, pre-rehabilitation center hospitalization, and rehabilitation center hospitalization were evident. CONCLUSION: After the implementation of CP, patients less often developed complications and displayed no changes in functional gain and efficiency. They had shorter LOS of total hospitalization, pre-rehabilitation center hospitalization and rehabilitation center hospitalization.

Terson Syndrome after Subarachnoid Hemorrhage Occurred by Thrombolysis and Mechanical Thrombectomy to Treat Acute Ischemic Stroke: A Case Report

Terson syndrome is a vitreous hemorrhage associated with subarachnoid hemorrhage. This can be caused by spontaneous, aneurysmal rupture or traumatic subarachnoid hemorrhage, but never has been reported as a consequence of hemorrhage due to thrombolysis and thrombectomy treatments of acute ischemic stroke patient. A 48-year-old man presented with left sided weakness was diagnosed as cerebral infarction on right middle cerebral artery territory due to complete occlusion of right distal internal carotid, middle cerebral, and anterior cerebral artery. He underwent thrombolysis and mechanical thrombectomy, and subarachnoid hemorrhage developed. Later, visual disturbance on right eye occurred so he was consulted to ophthalmology. Vitreous hemorrhage was found and surgery was recommended after two weeks of observation. After pars planar vitrectomy, visual acuity improved, along with functional ability. Therefore, possibilities of Terson syndrome in patients with subarachnoid hemorrhage have to be kept in mind to improve not only visual acuity but also rehabilitation outcome.

The Effect of Extracorporeal Shock Wave Therapy on Lower Limb Spasticity in Subacute Stroke Patients

OBJECTIVE: To evaluate the effect of extracorporeal shock wave therapy (ESWT) on lower limb spasticity in subacute stroke patients. METHODS: We studied thirty hemiplegic subacute stroke patients with ankle plantar flexor spasticity. ESWT was applied for 1 session/week, with a total of 3 sessions at the musculotendinous junction of medial and lateral gastrocnemius muscles. Patients were evaluated both clinically and biomechanically at baseline, after sham stimulation, and at immediately 1 week and 4 weeks after ESWT. For clinical assessment, Modified Ashworth Scale (MAS), clonus score, passive range of motion of ankle, and Fugl-Myer Assessment for the lower extremity were used. A biomechanical assessment of spasticity was conducted by an isokinetic dynamometer. Two parameters, peak eccentric torque (PET) and torque threshold angle (TTA), were analyzed at the velocities of 60degrees/sec, 180degrees/sec, and 240degrees/sec. RESULTS: After sham stimulation, there were no significant changes between each assessment. MAS and PET (180degrees/sec and 240degrees/sec) were significantly improved immediately and 1 week after ESWT. However, these changes were not significant at 4 weeks after ESWT. PET (60degrees/sec) and TTA (60degrees/sec, 180degrees/sec, and 240degrees/sec) were significantly improved immediately after ESWT. Yet, these changes were not significant at 1 week and 4 weeks after ESWT as well. CONCLUSION: Lower limb spasticity in subacute stroke patients was significantly improved immediately after ESWT. Although the therapeutic effect of ESWT reduced with time and therefore was not significant at 4 weeks after ESWT, the degree of spasticity was lower than that of the baseline. Future studies with a larger sample of patients are warranted in order to verify the protocols which can optimize the effect of ESWT on spasticity.

Muscle Cramps in Old Adults: Clinical Features and Pathophysiology

Muscle cramps are defined as painful, spasmodic, involuntary skeletal muscle contractions during or immediately after physical exercise. Muscle cramps have a typical clinical presentation, as the definition and the diagnosis is made based on a typical history together with the findings on clinical examination. Muscle cramps are self-extinguishing within seconds to minutes or relieved by stretching, and is often accompanied by a palpable knotting of the muscle. Old adults are prone to get muscle cramps, which may occur in patients with diseases, but also occur often in healthy subjects with no history of nervous system or metabolic disorders. Comorbidity and multiple medications, including diuretics due to an underlying disease, can be a part of the reason in old adults. We reviewed articles regarding the etiology of muscle cramps and introduced a new hypothesis of 'altered neuromuscular control', which has been documented recently.

Idiopathic Lumbosacral Plexopathy with Abnormal Finding in MRI: A case report

Idiopathic lumbosacral plexopathy is an uncommon idiopathic disorder characterized by acute onset of severe lower extremity pain, followed by weakness, atrophy of affected muscle, and variable sensory disturbance. A 61-year-old man experienced sudden onset of dysesthesia with weakness in right lower extremity. Electrodiagnostic study revealed patch pattern denervation at L3 and L4 root without paraspinal muscle involvement. Lumbar MRI showed abnormal signals in the right lumbar plexus. Pulse intravenous administration of high-dose immunoglobulin alleviated the sensorimotor symptoms. Abnormal signals in lumbar MRI reduced 6 months later.

Pyogenic Sacroiliitis with Psoas Abscess: A case report

Pyogenic sacroiliitis is a rare infection that may accompany psoas muscle abscess with vague clinical presentation, which present a diagnostic challenge requiring a high index of suspicion. We report a 48-year-old male, diagnosed pyogenic sacroiliitis with psoas abscess caused by Streptococcus intermedius and Sphingomonas paucimobilis. Magnetic resonance imaging showed multiloculated rim-enhancing lesion in right psoas muscle and joint effusion with osteomyelitis around sacroiliac joint. Intravenous antibiotics were administered after ultrasonographically guided abscess aspiration. Surgical drainage was done and his fever and symptom gradually subsided.

Usefulness of Electronic Pressure Algometer in Evaluation of Pressure Pain Threshold in Normal Korean Adults

OBJECTIVE: To examine pressure pain threshold (PPT) on several skeletal muscles in upper extremity, trunk, and lower extremity by using electronic pressure algometer and to evaluate it's interrater reliability, reproducibility, difference between gender and dominance, correlation with body mass index, and comparison among each muscles. METHOD: Forty healthy adults (male 27, female 13) were examined by two raters and reexamined in the same order after a rest of 10 minute. PPT at the splenius capitis, upper trapezius, infraspinatus, lumbar paraspinal muscle, extensor carpi radialis, vastus medialis, and gluteus medius muscles of both side was measured by medical electronic algometer. Rate of force application was approximately 2 lb/sec. Body mass index (BMI) was estimated from the individual's body weight by the square of their height. RESULTS: There were no statistical differences of PPTs at all muscles between two raters, between two test with time interval, and between dominant and nondominant side, respectively. PPT in man was higher than female at all muscles. There was significant correlation between BMI and PPT at lumbar paraspinal muscle, vastus medialis, and gluteus medius only in male. PPT was highest at lumbar paraspinal muscle and lowest at splenius capitis. CONCLUSION: Electronic pressure algometer is a reliable tool for evaluation of PPT which has high interrater reliability and high reproducibility and is not affected by dominance and location of muscles. Therefore, it is a useful clinical tool to compare PPT before and after treatment and to study the mechanism of musculoskeletal pain research program.
