Effect of functional electrical stimulation combined with stationary cycling and sit to stand training on mobility and balance performance in a patient with traumatic brain injury: A case report.

INTRODUCTION AND IMPORTANCE: This case study investigates the effects of functional electrical stimulation, stationary cycling, and sit-to-stand training in a patient with severe chronic traumatic brain injury. CASE PRESENTATION: The participant was a 24-year-old man with a traumatic brain injury two years prior to the intervention described in this case report. The accident caused right hemiplegia, right foot drop, aphasia, and poor coordination of movement in both upper and lower limbs. He was using a wheeled walker for functional mobility and was receiving routine rehabilitation before the initiation of treatment. A four week intervention in this study included functional electrical stimulation of the quadriceps and tibialis anterior muscles combined with stationary cycling and sit-to-stand training. CLINICAL DISCUSSION: Active and passive range of motion of right ankle dorsiflexion, strength of ankle dorsiflexor, balance performance, and mobility were measured before and after the intervention. Active range of motion of right ankle dorsiflexion increased by 8°. In addition, manual muscle test and Brief-BESTest scores increased from 3+ to 5 and from 7 to 9, respectively. Walking speed over the 10-m distance and timed up and go test score improved. CONCLUSION: Functional electrical stimulation combined with stationary cycling and sit-to-stand training resulted in increased muscle strength and range of motion, improved balance performance, and improved mobility in an individual with a traumatic brain injury.

Effects of Dry Needling on Connectivity of Corticospinal Tract, Spasticity, and Function of Upper Extremity in People with Stroke: Study Protocol for a Randomized Controlled Trial.

Background: Spasticity is a common motor disorder in adult stroke patients. Injury to the corticospinal tract (CST) is associated with spasticity. Dry needling (DN) has positive impacts on spasticity reduction and improvement in the range of motion (ROM) in stroke patients. This study aims to investigate the effectiveness of DN on the connectivity of the CST and the level of spasticity in adult stroke patients. Methods: This double-blind randomized controlled trial will enroll and randomly assign stroke patients to either the experimental group, for receiving three sessions of DN for the spastic wrist flexors, or the control group, for sham needling. The primary outcome measures will be diffusion tensor imaging and the Modified Modified Ashworth Scale score to assess CST connectivity and wrist flexor spasticity, respectively. The Box and Block Test and standard goniometry are the secondary outcome measures to assess hand dexterity and active and passive wrist ROM, respectively. Measurements will be taken both before and after the intervention. Discussion: The results of this study will provide important evidence of the effects of DN on CST connectivity, spasticity, and arm function in adult stroke patients. Trial registration: This trial is registered in the Iranian Registry of Clinical Trials (IRCT) (https://www.irct.ir; IRCT20191208045649N1).

The effects of cognitive versus motor demands on postural performance and weight bearing asymmetry in patients with stroke.

While several studies have investigated the interaction between postural control and secondary cognitive tasks in stroke patients, little is known about the influence of secondary motor task on postural control in these patients. The current research was designed to further examine dual-task performance by comparing the effects of cognitive versus motor dual-tasks on postural performance and weight bearing asymmetry (WBA) in stroke patients (n=23) relative to healthy, matched controls (n=22). All participants stood on dual-force plate under 5 conditions: (1) free standing; (2) simple cognitive task (easy Stroop) while standing; (3) difficult cognitive task (difficult Stroop) while standing; (4) simple motor task (holding a tray while a cylinder lying on its flat side) while standing; and (5) difficult motor task (holding a tray while a cylinder lying on its round side) while standing. The center of pressure (COP) measures was greater in stroke patients than healthy controls. Also, the WBA of the patients was greater than the controls. The COP measures increased when moving from single-task to cognitive dual-task conditions. No significant effect of motor dual-tasking was seen when moving from single-task to motor dual-task conditions. However, in contrast to cognitive dual-tasking, stroke patients and healthy controls employed different strategies during simultaneous performance of postural and motor tasks. It can be suggested that performing a motor task while standing requires greater attentional resources compared to performing a cognitive task while standing and this resulted in greater dual-task interference on motor performance in the stroke patients.
