Diaphragm ultrasonography and pulmonary function tests in patients with spinal cord injury.

STUDY DESIGN: Cross-sectional study. OBJECTIVE: To investigate the role of ultrasonographic measurement of the diaphragm thickness on pulmonary function tests in patients with spinal cord injury (SCI). SETTING: Rehabilitation center in Ankara, Turkey. METHODS: A total of 42 patients (34 M, 8 F) with SCI and 20 able-bodied volunteers (8 M, 12 F) were enrolled. Patients with SCI were divided into three groups according to their neurological (injury) levels. All participants underwent ultrasonographic measurements for diaphragm thickness on both sides and spirometric tests for pulmonary functions. The thickness ratio of the diaphragm was also calculated. RESULTS: There were seven patients (5 M, 2 F) in C2-C4 injury group, 14 patients (12 M, 2 F) in C5-T5 group, 21 patients (14 M, 7 F) in T6-L2 group, and 20 able-bodied volunteers (8 M, 12 F). The diaphragms of C2-C4 group were thicker than those of the controls at end-inspirium on the right side (2.7 ± 0.7 mm vs. 2.0 ± 0.5 mm; p = 0.035). The thickness ratios of C2-C4 group were lower than those of controls on the right (0.8 ± 0.4 vs. 1.5 ± 0.5; p = 0.005) and left (0.8 ± 0.5 vs. 1.6 ± 0.7; p = 0.003) sides. For all the pulmonary function tests (except for FEV1/FVC); patients with SCI had worse results than controls; and among the SCI groups, the higher the injury level, the worse the results. CONCLUSION: Although patients with high-level SCI had worse pulmonary function tests and decreased the contractile capacity of the diaphragm, they had thicker diaphragm muscles than controls. This may have been due to the compensatory effect of the diaphragm (performing its maximum contraction capacity and increasing frequency of inspiration).

Respiratory muscle training improves cardiopulmonary function and exercise tolerance in subjects with subacute stroke: a randomized controlled trial.

OBJECTIVE: To determine whether two types of exercise--breathing retraining (BRT) and inspiratory muscle training (IMT)--improve on cardiopulmonary functions and exercise tolerance in patients with stroke. DESIGN: A randomized controlled trial. SETTING: Education and research hospital. SUBJECTS: Forty-five inpatients with stroke (24 men, 21 women) were recruited for the study. The subjects were randomized into three groups: 15 assigned to receive inspiratory muscle training (IMT); 15 assigned to received breathing retraining, diaphragmatic breathing and pursed-lips breathing (BRT); 15 assigned to a control group. INTERVENTIONS: All study groups participated in a conventional stroke rehabilitation programme. For the same period, the IMT and BRT groups trained daily, six times a week, with each session consisting of one half-hour of training for six weeks. MAIN MEASURES: Each subject underwent pulmonary function and cardiopulmonary exercise tests. Subjects were also assessed for exertional dyspnoea, stages of motor recovery, ambulation status, activity of daily living and quality of life. RESULTS: After the training programme, the IMT group had significantly improved forced expiratory volume at 1 second (FEV(1)), forced vital capacity (FVC), vital capacity (VC), forced expiratory flow rate 25-75% (FEF 25-75%) and maximum voluntary ventilation (MVV) values compared with the BRT and control groups, although there were no significant differences between the BRT and control groups (P<0.01). Peak expiratory flow rate (PEF) value was increased significantly in the BTR group compared with the IMT and control groups. The IMT group also had significantly higher peak oxygen consumption (Vo(2peak)) than the BRT and control groups, although there were no significant differences between the BRT and control groups (P<0.001). There was a statistically significant increase in maximum inspiratory pressure (PI(max)) and maximum inspiratory and expiratory pressure (PE(max)) in the BRT group and, PI(max) in the IMT group compared with baseline and the control group. In the IMT group, this was associated with improvements in exercise capacity, sensation of dyspnoea and quality of life. CONCLUSIONS: Significant short-term effects of the respiratory muscle training programme on respiratory muscle function, exercise capacity and quality of life were recorded in this study.

Efficacy of combined oral-intravesical oxybutynin hydrochloride treatment for patients with overactive detrusors and indwelling urethral catheters.

The purpose of this article is to investigate the efficacy of intravesical oxybutynin hydrochloride (OH) to treat patients with overactive detrusors who are unresponsive to oral anticholinergic therapy alone. Twenty-five patients who were treated with oral OH for overactive detrusor (but who did not respond to treatment and were using indwelling urethral catheters) were given intravesical OH without changing oral treatment. Pre- and posttreatment bladder capacities were compared in urodynamic studies. The study showed that positive clinical results can be achieved with combined oral and intravesical OH treatments in patients with overactive detrusors who had indwelling urethral catheters because of severely reduced bladder capacity. However, a significant number of patients discontinued this treatment because of infection and difficulty in performing the procedure. Clinicians and rehabilitation nurses should provide education and support to eliminate these problems. In addition, the development of single-use standard sterile OH preparations for intravesical applications may increase the efficacy of the method.

Mirror therapy improves hand function in subacute stroke: a randomized controlled trial.

OBJECTIVE: To evaluate the effects of mirror therapy on upper-extremity motor recovery, spasticity, and hand-related functioning of inpatients with subacute stroke. DESIGN: Randomized, controlled, assessor-blinded, 4-week trial, with follow-up at 6 months. SETTING: Rehabilitation education and research hospital. PARTICIPANTS: A total of 40 inpatients with stroke (mean age, 63.2y), all within 12 months poststroke. INTERVENTIONS: Thirty minutes of mirror therapy program a day consisting of wrist and finger flexion and extension movements or sham therapy in addition to conventional stroke rehabilitation program, 5 days a week, 2 to 5 hours a day, for 4 weeks. MAIN OUTCOME MEASURES: The Brunnstrom stages of motor recovery, spasticity assessed by the Modified Ashworth Scale (MAS), and hand-related functioning (self-care items of the FIM instrument). RESULTS: The scores of the Brunnstrom stages for the hand and upper extremity and the FIM self-care score improved more in the mirror group than in the control group after 4 weeks of treatment (by 0.83, 0.89, and 4.10, respectively; all P<.01) and at the 6-month follow-up (by 0.16, 0.43, and 2.34, respectively; all P<.05). No significant differences were found between the groups for the MAS. CONCLUSIONS: In our group of subacute stroke patients, hand functioning improved more after mirror therapy in addition to a conventional rehabilitation program compared with a control treatment immediately after 4 weeks of treatment and at the 6-month follow-up, whereas mirror therapy did not affect spasticity.

Factors associated with health-related quality of life in patients with severe Guillain-Barré syndrome.

PURPOSE: To compare the health-related quality of life (HRQOL) in control subjects and patients with severe Guillain-Barré syndrome (GBS) 6 months after rehabilitation. To determine the relationship of several sociodemographic and medical factors with the HRQOL of the GBS survivors. METHODS: Thirty-one patients with severe GBS and 31 control subjects were included in the study. Demographic and medical variables were recorded. The functional outcome was measured using the Functional Independence Measure (FIM), both at admission and discharge and also at the 6-month follow-up examination. The HRQOLs were assessed by the Nottingham Health Profile (NHP) at the 6-month follow-up examination. RESULTS: There were significant improvements in functional status as measured by the FIM at discharge and also at 6 months. The scores of all of the NHP dimensions of the GBS patients were significantly higher than in the control subjects. Functional disability scores were highly related to the energy level, physical mobility and emotional reactions of the NHP domains. Education, gender, employment, mechanical ventilation and tendency to depression were the factors most related to the NHP domains. Age and marital status showed no significant correlation with the NHP scores. CONCLUSION: The HRQOL of the GBS patients remains lower than that of the control subjects. In addition to functional scores, several sociodemographic and medical variables, such as education, psychological factors, gender, mechanical ventilation and employment may play a crucial role in determining the quality of life in persons with GBS.

Comparison of rehabilitation outcome in patients with aphasic and non-aphasic traumatic brain injury.

OBJECTIVE: To compare the functional, cognitive and disability status of aphasic and non-aphasic traumatic brain injury patients. DESIGN: A prospective comparative study in which 103 patients with traumatic brain injury participated. SUBJECTS: Fifty-one aphasic and 52 non-aphasic patients with traumatic brain injury. METHODS: Functional Independence Measure and Disability Rating Scale were used to determine functional status and disability. Cognitive status was evaluated by the Mini-Mental Status Examination. Aphasic patients were evaluated using the Gülhane Aphasia Test for language disorders. RESULTS: The most frequent type of aphasia was Broca aphasia at 26.49% followed by anomic at 19.6% and trans-cortical motor at 15.6%. Functional Independence Measure, Disability Rating Scale and Mini-Mental Status Examination scores at admission and at discharge showed significant differences in aphasic patients (p<0.001). There were no significant differences in the Functional Independence Measure, Disability Rating Scale and Mini-Mental Status Examination gains between the aphasic and non-aphasic patients (p>0.01). CONCLUSION: Although aphasia could be accepted as a negative prognostic indicator in patients with traumatic brain injury, we could not detect any difference in functional and cognitive gains between the aphasic and non-aphasic patients.

Reflex sympathetic dystrophy in hemiplegia.

There is a high incidence of reflex sympathetic dystrophy of the upper limbs in patients with hemiplegia, and its painful and functional consequences present a problem to specialists in physical medicine and rehabilitation. This study was designed to assess the role of several factors in the occurrence of reflex sympathetic dystrophy in patients with hemiplegia. Ninety-five consecutive stroke patients (63 male and 32 female, mean age 59+/-12 years) admitted to our hospital were evaluated. Of the study group, 29 patients (30.5%) were found to develop reflex sympathetic dystrophy. There were no significant differences between the hemiplegic patient groups with or without reflex sympathetic dystrophy regarding age, gender, etiology, side of involvement, disease duration and the presence of comorbidities. The recovery stages of hemiplegia, as shown by Brunnstrom functional classification, were significantly different between the two groups; patients in lower recovery stages tended to develop reflex sympathetic dystrophy more frequently (P<0.01). Additionally, the presence of flaccidity was also a significant factor in the development of reflex sympathetic dystrophy. Glenohumeral subluxation was present in 37 patients (38.9%) in our study group and the presence of this complication was related to the occurrence of reflex sympathetic dystrophy. The presence of glenohumeral subluxation was significantly higher in patients with reflex sympathetic dystrophy (21/29, 72.4%) when compared to the patients without reflex sympathetic dystrophy (16/66, 24.2%) (P<0.001). Also, hemiplegic patients with more severe shoulder subluxation were significantly more likely to develop reflex sympathetic dystrophy. These results suggest that lower recovery stages, reduced tonus and glenohumeral subluxation significantly contribute to the occurrence of reflex sympathetic dystrophy in the hemiplegic patient. We believe that preventive and treatment measures should consider these factors as they seem to have in common a higher risk of traumatizing the paralyzed upper limb and causing reflex sympathetic dystrophy.

Does delayed correction interfere with pulmonary functions and exercise tolerance in patients with tetralogy of fallot?

STUDY OBJECTIVES: To assess exercise tolerance and determine the distinct role of cardiac, respiratory, or peripheral factors on it after delayed surgical repair in patients with tetralogy of Fallot. DESIGN: The aerobic exercise capacity of 15 adult patients (mean [+/- SD] age, 21 +/- 6; age range, 9 to 30 years) undergoing successful total correction at a mean age of 12 +/- 5 years (patients) was compared to healthy, matched control subjects by using right ventricle echocardiography, resting spirometry, and cardiopulmonary exercise tests at a mean postoperative time of 7.5 +/- 4.6 years. SETTING: Tertiary care referral centers. PATIENTS: Fifteen adult patients (mean age, 21 +/- 6 years; age range, 9 to 30 years) undergoing successful total correction at a mean age of 12 +/- 5 (patients) and 15 healthy, matched volunteers (control subjects). RESULTS: There was evidence for a slight right ventricular diastolic dysfunction in the patients. Mean FVC (88 +/- 9% vs 109 +/- 12% predicted, respectively) and FEV1 (89 +/- 9% vs 109 +/- 12% predicted, respectively), although being within the normal range, were also decreased in comparison to those of control subjects (p < 0.0001). Maximal oxygen consumption (V(O2max) decreased in both groups (55 +/- 16% vs 61 +/- 23% predicted, respectively; p = 0.5); however, there were more individuals with severely decreased values among the patients (p = 0.05). V(O2) at the anaerobic threshold was also decreased in patients (33 +/- 15% vs 51 +/- 8% predicted, respectively; p = 0.004). The maximum tolerable exercise time was 17.3 +/- 4.5 min in patients vs 21.2 +/- 6.4 min in control subjects (p = 0.06). CONCLUSIONS: The exercise capacity after delayed repair was good in general compared to matched control subjects; however, exercise capacity may be slightly limited by ventilatory dysfunction, low anaerobic threshold, and lack of physical fitness despite New York Heart Association class improvement after undergoing the operation.

Fever during post-acute rehabilitation in patients with brain injury.

OBJECTIVE: To investigate the incidence of fever during the post-acute rehabilitation phase in patients with brain injury. DESIGN: Prospective study. SUBJECTS: Seventy-four patients with brain injury. METHODS: Patients were evaluated for the presence of fever during the rehabilitation phase. Demographics, time since injury, acute hospital and rehabilitation stay, brain injury and clinical characteristics were recorded for all subjects. RESULTS: Of the study group, 36 patients (36/74; 48.6%) had at least 1 event qualified as fever. The most common cause of fever was urinary tract infection. There were only 2 patients considered as having central fever. Fever was significantly more frequent in patients with a greater number of neurological impairments, more severe neurological impairments and a lower level of independence. The rehabilitation stay was prolonged in patients with fever. The average length of rehabilitation stay was 62.5 days and 49.8 days in patients with or without fever, respectively. CONCLUSION: Infection is the most common cause of fever after brain injury and the incidence of central fever is low.

Efficacies of papaverine and sildenafil in the treatment of erectile dysfunction in early-stage paraplegic men.

The aim of the study was to determine which vasoactive agent was more efficacious for erectile dysfunction (ED), intracavernosal papaverine or oral sildenafil, in paraplegic men within the first year after injury by using a penile color Doppler ultrasound as a quantitative imaging method and to determine the association between responses to these two vasoactive agents and factors such as neurological lesion level and lesion severity. A total of 31 male in-patients with spinal cord injury, aged over 18 years, and with neurological lesions below the T6 level within the first year after injury with ED were included. Visual and auditory sexual stimulus (VASS) on day 1 (group 1), VASS with 25 mg intracavernosal papaverine (group 2) and after a wash-out period of papaverine on day 2, and VASS with 50 mg oral sildenafil on day 5 (group 3) were administered to each patient. Measurements of the peak systolic velocity and end diastolic velocity, which were used as vascular parameters during each procedure type, were taken using penile color Doppler ultrasound. Considering the severity of the lesion and the levels of the neurological lesion, there was a statistically significant difference between the PSV values of the group 1 and the other two groups (P<0.05). There was no statistically significant difference between the peak systolic velocity and end diastolic velocity values of groups 2 and 3 (P>0.05) in terms of both the severity and the levels of the lesion. Efficacies of intracavernosal papaverine hydrochloride or oral sildenafil citrate for ED were similar at all neurological lesion levels and lesion severity in paraplegic men within the first year after spinal cord injury.

Low-frequency pulsed electromagnetic field therapy in fibromyalgia: a randomized, double-blind, sham-controlled clinical study.

OBJECTIVE: To evaluate the clinical effectiveness of low-frequency pulsed electromagnetic field (PEMF) therapy for women with fibromyalgia (FM). METHODS: Fifty-six women with FM, aged 18 to 60 years, were randomly assigned to either PEMF or sham therapy. Both the PEMF group (n=28) and the sham group (n=28) participated in therapy, 30 minutes per session, twice a day for 3 weeks. Treatment outcomes were assessed by the fibromyalgia Impact questionnaire (FIQ), visual analog scale (VAS), patient global assessment of response to therapy, Beck Depression Inventory (BDI), and Short-Form 36 health survey (SF-36), after treatment (at 4 wk) and follow-up (at 12 wk). RESULTS: The PEMF group showed significant improvements in FIQ, VAS pain, BDI score, and SF-36 scale in all domains at the end of therapy. These improvements in FIQ, VAS pain, and SF-36 pain score during follow-up. The sham group also showed improvement were maintained on all outcome measures except total FIQ scores after treatment. At 12 weeks follow-up, only improvements in the BDI and SF-36 scores were present in the sham group. CONCLUSION: Low-frequency PEMF therapy might improve function, pain, fatigue, and global status in FM patients.

Adult case of acrodysostosis with severe neurologic involvement.

OBJECTIVE: Acrodysostosis is a rare syndrome characterized by peripheral dysostosis, nasal hypoplasia and frequently mental retardation. Only one adult case of acrodysostosis has been reported to have neurologic symptoms. We report one further adult case of acrodysostosis with severe neurologic findings including myelopathy and spastic paraparesis due to diffuse spinal stenosis and recurrent deep vein thrombosis possibly caused by neurologic deficits. RESULTS: We report a 43-year-old woman who had back and neck pain with weakness in the extremities of several years. 1~year before admission to our hospital, she had been treated with a missed diagnosis of sero (-) spondyloarthropathy but had not benefited. She became unable to walk, thereafter she underwent decompression surgery with a diagnosis of degenerative spinal stenosis. She presented at our outpatient department complaining of lowback pain and difficulty walking. She had marked facial and peripheral appearance of acrodysostosis. Spinal MRI revealed extensive spinal stenosis. A diagnosis was made through the genetic investigation, clinical and radiological findings. Spastic paraparesis were detected. There was widespread neuropathic pain. 15 days after admission, she developed swelling and redness of the left lower extremity and the venous doppler ultrasonography showed left acute and right past DVT. We treated DVT with anticoagulant therapy. Gabapentin and Baclofen were initiated for neuropathic pain and spasticity. A conventional rehabilitation program was performed. She left walking with a walker without pain and spasticity. CONCLUSIONS: We would like to remind physicians to be aware of peripheral malformations as signs of skeletal dysplasias and to consider acrodysostosis in the differential diagnosis. Although it is a rare condition, if diagnosed early, possible complications can be treated and outcomes may be improved.

Spinal cord injury associated with thoracic osteoporotic fracture.

This report details a case of sudden neurologic deficit attributable to acute thoracic fractures associated with senile osteoporosis. A 73-yr-old female patient with a history of occasional back pain during the past 4 mos had sudden thoracic vertebral fracture with spinal cord injury. The patient, who had a benign past medical history, had not been evaluated for osteoporosis. Thoracic spine radiographs showed a compression fracture at T8. Thoracic magnetic resonance imaging exposed a compression fracture at T7-T8. She was treated operatively. She was found to have spinal cord injury with American Spinal Injury Association classification C (T7), and she had poor sitting balance. She was discharged in a wheelchair and was administered clean intermittent catheterization every 6 hrs. Six months after discharge, she ambulated with a walker and had spontaneous micturition. Vertebral fractures are a common presentation of senile osteoporosis. The risk of neurologic impairment attributable to vertebral fracture is a rare but potentially severe complication. Besides medical therapy and suitable rehabilitation programs, surgical treatment is an integral part of the management of patients with osteoporotic vertebral fractures.

Functional and cognitive progress in aphasic patients with traumatic brain injury during post-acute phase.

OBJECTIVES: To investigate the relationship between language functions and cognitive and functional outcome and to evaluate the effects of a conventional language rehabilitation programme on aphasic adult patients in the post-acute stage of traumatic brain injury (TBI). DESIGN: Non-concurrent prospective study. Patients were assessed pre-treatment and post-treatment with standardized assessment tools. SUBJECTS: Sixty-one aphasic patients with TBI who were admitted to a rehabilitation centre in the post-acute phase for a late inpatient rehabilitation programme. METHODS: The motor sub-scales of the Functional Independence Measures and Disability Rating Scale were used to assess functional status and disability. Cognitive status was evaluated with the Mini-Mental Status Examination and the Functional Independence Measure cognitive sub-scale. The language function was evaluated with the Gülhane Aphasia Test. RESULTS: All functional, cognitive and language scores increased significantly during the rehabilitation programme. Language functions at admission were correlated with the Functional Independence Measure motor change scores and the Mini-Mental Status Examination change scores. Regression analyses revealed that auditory comprehension at admission was the most important independent determinant of functional and cognitive gain during rehabilitation. CONCLUSION: Post-acute language functions after late admission to a rehabilitation centre appear to be related to measures of cognitive and functional progress in patients with TBI. Functional and cognitive outcome is mainly affected by auditory comprehension. Results also showed the effectiveness of post-acute conventional rehabilitation in improving language functions.
