To investigate the factors influencing the quiet standing balance of patients with incomplete cervical spinal cord injuries. Also to find the correlations between posturographic parameters and clinical balance tests as well as to find the correlation between posturographic parameters and functional independence.We conducted a tetra-ataxiometric posturography, lower extremity motor score (LEMS), Korean version of the Berg Balance Scale (K-BBS), Timed Up and Go test (TUG), and Korean Version of the Modified Barthel Index (K-MBI) of 10 patients. 10 healthy adults carried out the posturography. We checked stability, weight distribution, Fourier and synchronization indices of eight positions, and the fall index of the posturography.The patient group showed significantly higher stability and weight distribution indices in all eight positions. Stability indices significantly increased with eyes closed or standing on pillows. Weight distribution indices were significantly higher with eyes closed or the head bent backwards. The patient group showed significantly higher Fourier indices of low, low-medium, and high frequency in eight positions. The Fourier indices at high-medium frequency were significantly higher with eyes closed on pillows or in variable head positions. There were no significant differences of synchronization indices between the patient and the control group. The falling index of the patient group significantly correlated with K-BBS, TUG, and K-MBI. LEMS had significant correlation with some synchronization indices, but not with the falling index.The quiet standing balance of the patients was influenced by somatosensory limitations or insufficient visual compensation. We should try to improve the postural balance and functional independence of patients through proper proprioceptive and lower extremity strength training for better postural and pedal control, and to make efforts to minimize environmental hazards.

To investigate the feasibility and effects of balance training with a newly developed Balance Control Trainer (BCT) that applied the concept of vertical movement for the improvements of mobility and balance in chronic stroke patients.Forty chronic stroke patients were randomly assigned to an experimental or a control group. The experimental group (n=20) underwent training with a BCT for 20 minutes a day, 5 days a week for 4 weeks, in addition to concurrent conventional physical therapy. The control group (n=20) underwent only conventional therapy for 4 weeks. All participants were assessed by: the Functional Ambulation Categories (FAC), 10-meter Walking Test (10mWT), Timed Up and Go test (TUG), Berg Balance Scale (BBS), Korean Modified Barthel Index (MBI), and Manual Muscle Test (MMT) before training, and at 2 and 4 weeks of training.There were statistically significant improvements in all parameters except knee extensor power at 2 weeks of treatment, and in all parameters except MBI which showed further statistically significant progress in the experimental group over the next two weeks (p<0.05). Statistically significant improvements on all measurements were observed in the experimental group after 4 weeks total. Comparing the two groups at 2 and 4 weeks of training respectively, 10mWT, TUG, and BBS showed statistically more significant improvements in the experimental group (p<0.05).Balance training with a newly developed BCT is feasible and may be an effective tool to improve balance and gait in ambulatory chronic stroke patients. Furthermore, it may provide additional benefits when used in conjunction with conventional therapies. HubMed – rehab

To examine the effects of a bedside exercise program on the recovery of swallowing after a stroke.Fifty stroke patients with dysphagia (<6 months post-stroke) were enrolled and classified into two groups, the experimental (25 subjects) and control groups (25 subjects). The control group was treated with conventional swallowing therapy. The experimental group received additional bedside exercise training, which consisted of oral, pharyngeal, laryngeal, and respiratory exercises, 1 hour per day for 2 months, and they were instructed regarding this program through the nursing intervention. All patients were assessed for their swallowing function by Videofluoroscopic Swallowing Study (VFSS), using the New VFSS scale, the level of functional oral intake, the frequency of dysphagia complications, the presence (or not) of tube feeding, the mood state and quality of life before the treatment and at 2 months after the treatment.After 2 months of treatment, the experimental group showed a significant improvement in the swallowing function at the oral phase in the New VFSS Scale than that of the control group (p<0.05). Further, they also showed less depressive mood and better quality of life than the control group. However, there was no significant change in the incidence of dysphagia complication and the presence (or not) of tube feeding between the two groups.Bedside exercise program showed an improvement of swallowing function and exhibited a positive secondary effect, such as mood state and quality of life, on subacute stroke patients with dysphagia. For improvement of rehabilitation results on subacute stroke patients with dysphagia, this study suggests that additional intensive bedside exercise would be necessary. HubMed – rehab

 

Prediction of Motor Function Recovery after Subcortical Stroke: Case Series of Activation PET and TMS Studies.

To examine whether the pattern of brain activation induced by a motor task and the motor responses to transcranial magnetic stimulation (TMS) have prognostic implications for motor recovery after stroke.Ten patients with first-ever subcortical stroke (55.7±17.3 years, 5 ischemic and 5 hemorrhagic) underwent 2 FDG PET studies under different conditions (1: rest, 2: activation with a specific motor task) at 37.7±25.2 days after stroke. The regions showing more than a 10% increase in glucose metabolism on subtraction images during activation and rest were considered to be significantly activated. Cortical excitability of intracortical inhibition (ICI) and intracortical facilitation (ICF) were assessed using the TMS from both abductor pollicis brevis muscles within 7 days of PET scans. Recovery of motor function was assessed at the point of the neurological plateau.The presence of a motor response at the plegic site to TMS and normal intracortical inhibition, and facilitation patterns in the unaffected hemisphere were found to be related to good recovery. An association between an ipsilesional activation on PET and good motor recovery was also observed, but this was significantly weaker than that between TMS measured cortical excitability and motor recovery.Integrity of the ipsilesional corticospinal pathway, normalized contralesional intracortical excitability, and task-related activation in the ipsilesional hemisphere were found to predict post-stroke motor recovery significantly.
