J Michio Clark, Andrew Post, T Blaine Hoshizaki, Michael D Gilchrist
In ice hockey, concussions can occur as a result of many different types of impact events, however hockey helmets are certified using a single injury scenario, involving drop tests to a rigid surface. The purpose of this study is to measure the protective capacity of ice hockey helmets for different impact events in ice hockey. A helmeted and unhelmeted Hybrid III headform were impacted simulating falls, elbow, shoulder and puck impacts in ice hockey. Linear and rotational acceleration and maximum principal strain (MPS) were measured...

BACKGROUND: Resistance from antagonistic muscle groups might be a crucial factor reducing function in chronic hemiparesis. The resistance due to spastic co-contraction might be reduced by botulinum toxin injections. We assessed the effects of abobotulinumtoxinA injection in the upper limb muscles on muscle tone, spasticity, active movement, and function. METHODS: In this randomised, placebo-controlled, double-blind study, we enrolled adults (aged 18-80 years) at least 6 months after stroke or brain trauma from 34 neurology or rehabilitation clinics in Europe and the USA...

BACKGROUND: Shoulder pain after a cerebrovascular accident or traumatic brain injury is a common but often under-recognized problem. It is due to a number of causes including inferior subluxation, spasticity, adhesive capsulitis, and heterotopic ossification. Many of these are amenable to surgical intervention. METHODS: Literature review of current evidence. RESULTS: This article shows that there are multiple treatment options in this group of patients, and it is important to understand these as clinicians in delivering quality care to this complex group of patients...

BACKGROUND: Severe immobility due to lesions of the brain necessitates therapeutic positioning over the long term. There is little scientific evidence concerning the efficacy of different positioning methods. This clinical trial compares the effects of conventional positioning (CON) with those of positioning in neutral (LiN). METHODS: A prospective, multicenter, investigator-blinded, randomized, controlled trial was performed on a total of 218 non-ambulatory patients (underlying disease: stroke, 141 patients; hypoxic brain damage, 28; traumatic brain injury, 20; other, 29)...

BACKGROUND: In recent years, the incidence of injury in older people has increased. The aim of this study is to address the hypothesis that this increase is due to an increase in the incidence of some injuries that, while less common than hip fractures, are sufficient jointly to counteract the decrease or stabilisation in hip fracture rates observed in most countries. METHODS: We performed a descriptive study of trends using data from the National Hospital Discharge Register...

OBJECTIVE: The neurobehavioural symptoms and pain following traumatic brain injury (TBI) can be long-lasting. The condition impairs the persons' ability to function in their work, studies and gatherings with family and friends. The aim of this study was to investigate dosage, safety and effects of methylphenidate on mental fatigue and pain. METHODS: Twenty-nine physically-well rehabilitated TBI victims, 28 with a mild TBI and one with TBI and also with pain in the neck, shoulders and head were included in the study...

BACKGROUND: The corticoreticular pathway (CRP) innervates the proximal muscles of extremities and axial muscles; therefore, it is involved in postural control and gait. We report on a patient who exhibited proximal weakness due to a CRP injury, which was evaluated using diffusion tensor tractography (DTT). METHODS: A 62-year-old male patient who had been injured in a traffic accident underwent conservative management for a contusional hemorrhage in the right frontotemporal lobes, and a subdural and epidural hematoma in the right temporoparietal lobes...

BACKGROUND: Heterotopic ossification (HO) of the shoulder after central nervous system damage has seldom been studied. MATERIALS AND METHODS: We performed a single-center retrospective study from 1993 to 2009 including patients who underwent surgery for troublesome shoulder HO. Demographic data, HO location, surgical approach, preoperative and postoperative shoulder range of motion, etiologies, and postoperative complications were collected from patients' files...

OBJECTIVE: To determine the sensitivity of the Nociception Coma Scale (NCS), the first scale developed to assess nociceptive pain in vegetative state and minimally conscious state patients, in comparing behavioural changes in response to noxious versus non-noxious stimulation. METHODS: The NCS was administered to assess patients' responses in three conditions: (1) baseline (observation of spontaneous behaviours), (2) non-noxious/tactile stimulation (taps on the patient's shoulder), and (3) noxious stimulation (pressure on the nail bed)...

BACKGROUND: We retrospectively reviewed 10 consecutive patients (11 shoulders) with traumatic brain injury who underwent surgical resection of heterotopic ossification (HO) of the shoulder. Our primary research goal was to determine the change in range of motion (ROM) at the shoulder after resection of heterotopic ossification in patients with traumatic brain injury. Secondary research goals were to determine simple functional outcome gains related to activities of daily living and to determine complications in this patient cohort...

Shaken baby syndrome is a serious form of physical child abuse, which is frequently overlooked. It is defined as vigorous manual shaking of an infant who is being held by the extremities or shoulders, leading to whiplash-induced intracranial and intraocular bleeding and no external signs of head trauma. This syndrome is seen most commonly in children under 2 years, mainly in children under 6 months. This article summarizes issues related to clinical presentation, diagnosis, risk factors, and interventions for healthcare professionals...

BACKGROUND: Bodychecking is a leading cause of injury among minor hockey players. Its value has been the subject of heated debate since Hockey Canada introduced bodychecking for competitive players as young as 9 years in the 1998/1999 season. Our goal was to determine whether lowering the legal age of bodychecking from 11 to 9 years affected the numbers of all hockey-related injuries and of those specifically related to bodychecking among minor hockey players in Ontario. METHODS: In this retrospective study, we evaluated data collected through the Canadian Hospitals Injury Reporting and Prevention Program...

Alcohol-related falls are recognized as a major contributor to the occurrence of traumatic brain injury. The control of upright standing balance is complex and composes of contributions from several partly independent mechanisms such as appropriate information from multiple sensory systems and correct feedback and feed forward movement control. Analysis of multisegmented body movement offers a rarely used option for detecting the fine motor problems associated with alcohol intoxication. The study aims were to investigate whether (1) alcohol intoxication at 0...

BACKGROUND: Patients with spastic hemiparesis after upper motor neuron (UMN) injury often exhibit limited shoulder movement. We evaluated the outcomes of shoulder tendon fractional lengthenings in patients with spasticity and preserved volitional control. METHODS: A consecutive series of 34 adults with spastic hemiparesis from UMN injury (23 post-stroke, 11 post-traumatic brain injury) and limited shoulder movement with preserved volitional motor control who underwent shoulder tendon fractional lengthenings (pectoralis major, latissimus dorsi, teres major) were evaluated...

Numerous haptic devices have been developed for upper-limb neurorehabilitation, but their widespread use has been largely impeded because of complexity and cost. Here, we describe a variable structure pantograph mechanism combined with a spring suspension system that produces a versatile rehabilitation robot, called Universal Haptic Pantograph, for movement training of the shoulder, elbow, and wrist. The variable structure is a 5-degree-of-freedom (DOF) mechanism composed of 7 joints, 11 joint axes, and 3 configurable joint locks that reduce the number of system DOFs to between 0 and 3...

BACKGROUND: Heterotopic ossification (HO) is a frequent complication after central nervous system (CNS) damage but has seldom been studied. We aimed to investigate features of HO for the first time in a large sample and the rate of early recurrence of HO in terms of the time of surgery. METHODOLOGY/PRINCIPAL FINDINGS: We retrospectively analyzed data from an anonymous prospective survey of patients undergoing surgery between May 1993 and November 2009 in our institution for troublesome HO related to acquired neurological disease...

Numerous haptic devices have been developed for neurorehabilitation of upper extremities, but their wide-spread use has been largely impeded for reasons of complexity and cost. In this paper we describe a variable structure pantograph mechanism that produces a versatile rehabilitation robot for movement training of the shoulder, elbow, and wrist. The device has three operational modes: ARM, REACH and WRIST. The performance of the mechanism, driven by series elastic actuators, is similar in all three operational modes while using a single control scheme and set of gains...
