Flexor tenotomies for the treatment of bilateral wrist contracture after traumatic brain injury: A case report

Traumatic brain injuries have the potential to cause the development of long-term complications. We aim to show that the use of flexor tenotomies in the treatment of flexion contractures following traumatic brain injury is a viable solution.

Serial Casting of the Ankle and Knee in a Child With Vascular Anomaly of the Calf Musculature: A Case Report

BACKGROUND AND PURPOSE

Contracture and toe-walking in children due to vascular anomaly of the calf musculature is rarely described, and there is limited evidence regarding treatment. The purpose of this case is to describe the novel use of serial casting, combining the knee and ankle, to reduce contracture in a child with hemangioma of the calf.

CASE DESCRIPTION

An 11-year-old girl received 12 casts of the ankle and knee, followed by custom orthotics, to address chronic contracture and gait impairments caused by a vascular anomaly in the posterior compartment of the lower extremity.

OUTCOMES

After casting, the patient had fully restored knee range of motion and improved ankle range of motion by 45 degrees. She received custom orthotics and maintained her range of motion 4 months after casting.

DISCUSSION

Serial casting of the knee and ankle may be a useful alternative to surgical lengthenings in patients with chronic contractures caused by vascular anomalies of the lower extremity.

Evidence-based position paper on Physical and Rehabilitation Medicine professional practice for Adults with Acquired Brain Injury. The European PRM position (UEMS PRM Section)

BACKGROUND

Acquired brain injury (ABI) is damage to the brain that occurs after birth caused either by a traumatic or by a nontraumatic injury. The rehabilitation process following ABI should be performed by a multi-professional team, working in an interdisciplinary way, with the aim of organizing a comprehensive and holistic approach to persons with every severity of ABI. This Evidence Based Position Paper represents the official position of the European Union through the UEMS Physical and Rehabilitation Medicine (PRM) Section and designates the professional role of PRM physicians for people with ABI. The aim was to formulate recommendations on the PRM physician's professional practice for persons with ABI in order to promote their functioning and enhance quality of life.

METHODS

This paper has been developed according to the methodology defined by the Professional Practice Committee of the UEMS-PRM Section: a systematic literature search has been performed in PubMed and Core Clinical Journals. On the basis of the selected papers, recommendations have been made as a result of five Delphi rounds.

RESULTS

The literature review as well as thirty-one recommendations are presented.

CONCLUSIONS

The expert consensus is that structured, comprehensive and holistic rehabilitation program delivered by the multi-professional team, working in an interdisciplinary way, with the leadership and coordination of the PRM physician, is likely to be effective, especially for those with severe disability after brain injury.

Non-surgical Intervention of Knee Flexion Contracture in Children with Spina Bifida: Case Report

[Purpose] The purpose of this case report is to describe for the first time, the use of serial casting in the management of knee joint flexion contracture for a young child with spina bifida. [Case Description] The child was 6 years old, and had L3–L4 spina bifida level lesion with quadriceps muscle strength grade 3 +. The child had previously received weekly physiotherapy including stretching for knee flexion contracture on both lower limbs, but without improvement. [Results] The knee flexion contracture, which was not corrected with passive stretching, improved with casting from −40° knee extension to −5° knee extension as measured by a standard goniometer over a period of 4 weeks. Careful measures were taken to ensure skin integrity. At follow up after one-year, the child could ambulate independently with the help of walking aids. [Conclusion] The outcome indicates that using serial casting and follow-up with the use of bracing may be useful for enhancing the walking ability of a young child with spina bifida with knee flexion contractures. Further investigations of serial casting as well as investigation of serial casting with other interventions are warranted.

Effects of a Pelvic Belt on the EMG Activity of the Abdominal Muscles during a Single-leg Hold in the Hook-lying Position on a Round Foam Roll

[Purpose] This study investigated the effects of a pelvic belt on the electromyography (EMG) activity of the abdominal muscles during a single-leg hold in the hook-lying position on a round foam roll. [Subjects] Seventeen healthy female volunteers were recruited for this study. [Methods] The participants performed single-leg-hold exercises on a round foam roll with and without a pelvic belt. Surface EMG was recorded from the rectus abdominis (RA), internal oblique (IO), and external oblique (EO) bilaterally. [Results] The EMG activity of the bilateral RA, EO, and IO was significantly lower when the pelvic belt applied. [Conclusions] Our finding that the bilateral EO, IO, and RA muscles were less active with a pelvic belt during trunk-stabilizing exercises on an unstable surface suggests that the pelvic belt provided "form closure".

Systematic review of contracture reduction in the lower extremity with dynamic splinting

Introduction

Joint contractures are relatively common disorders that can result in significant, long-term morbidity. Initial treatment is non-operative and often entails the use of mechanical modalities such as dynamic and static splints. Although widely utilized, there is a paucity of data that support the use of such measures. The purpose of this systematic review was to evaluate the safety and efficacy of dynamic splinting as it is used to treat joint contracture in lower extremities, and to determine if duration on total hours of stretching had an effect on outcomes.

Methods

Reviews of PubMed, Science Direct, Medline, AMED, and EMBASE websites were conducted to identify the term ‘contracture reduction’ in manuscripts published from January 2002 to January 2012. Publications selected for inclusion were controlled trials, cohort studies, or case series studies employing prolonged, passive stretching for lower extremity contracture reduction. A total of 354 abstracts were screened and eight studies (487 subjects) met the inclusion criteria. The primary outcome measure was change in active range of motion (AROM).

Results

The mean aggregate change in AROM was 23.5º in the eight studies examined. Dynamic splinting with prolonged, passive stretching as home therapy treatment showed a significant direct, linear correlation between the total number of hours in stretching and restored AROM. No adverse events were reported.

Discussion

Dynamic splinting is a safe and efficacious treatment for lower extremity joint contractures. Joint specific stretching protocols accomplished greater durations of end-range stretching which may be considered to be responsible for connective tissue elongation.

Specialized early treatment for persons with disorders of consciousness: program components and outcomes

OBJECTIVES

To describe a specialized early treatment program for persons with disorders of consciousness (DOC) that includes family education; to identify rates of secondary conditions, imaging used, and selected interventions; and to evaluate outcomes.

DESIGN

A single-center, retrospective, pre-post design using electronic medical record data.

SETTING

A Commission on Accreditation of Rehabilitation Facilities-accredited, long-term acute care hospital that provides acute medical and inpatient rehabilitation levels of care for people with catastrophic injuries.

PARTICIPANTS

Persons (N=210) aged 14 to 69 years with DOC of primarily traumatic etiology admitted at a mean ± SD of 41.0 ± 27.2 days postinjury; 2% were in coma, 41% were in the vegetative state, and 57% were in the minimally conscious state.

INTERVENTIONS

An acute medical level of care with ≥90 minutes of daily interdisciplinary rehabilitation and didactic and hands-on caretaking education for families.

MAIN OUTCOME MEASURES

Coma Recovery Scale-Revised, Modified Ashworth Scale, and discharge disposition.

RESULTS

Program admission medical acuity included dysautonomia (15%), airway modifications (79%), infections (eg, pneumonia, 16%; urinary tract infection, 14%; blood, 11%), deep vein thrombosis (17%), pressure ulcers (14%), and marked hypertonia (30% in each limb). There were 168 program interruptions (ie, 139 surgeries, 29 nonsurgical intensive care unit transfers). Mean length of stay ± SD was 39.1 ± 29.4 days (range, 6-204d). Patients showed improved consciousness and respiratory function and reduced presence or severity of pressure ulcers and upper extremity hypertonia. At discharge, 54% showed sufficient emergence from a minimally conscious state to transition to mainstream inpatient rehabilitation, and 29% did not emerge but were discharged home to family with ongoing programmatic support; only 13% did not emerge and were institutionalized.

CONCLUSIONS

Persons with DOC resulting primarily from a traumatic etiology who receive specialized early treatment that includes acute medical care and ≥90 minutes of daily rehabilitation are likely to show improved consciousness and body function; more than half may transition to mainstream inpatient rehabilitation. Families who receive comprehensive education and hands-on training with ongoing follow-up support may be twice as likely to provide care for medically stable persons with DOC in their homes versus nursing facility placement.

Botulinum toxin type-A and plaster cast treatment in children with upper brachial plexus palsy

BACKGROUND AND PURPOSE

Electrical stimulation, physical therapy and occupational therapy remain the main treatment for children with upper brachial plexus palsy (UBPP), when surgery has been excluded. A pilot study was undertaken to investigate whether botulinum toxin type A (BoNT-A) and plaster casting, as adjunct to the physical therapy, decreased muscle contracture and improved the position and function of the impaired arm.

METHOD

Twenty-two children (mean age 5.6 +/- 3.4 years) with mild UBPP who previously underwent serial cast treatment, unsuccessfully, were enrolled. Neurological impairment and functional status were quantified using Medical Research Council (MRC) and Mallet scales and the Nine-Hole Peg Test (NHPT). Elbow extension was measured using a goniometer. Biceps brachii, brachialis, pronator teres and pectoralis major muscles were injected with 22 units kg(-1) BoNT-A (Dysport, Ipsen). After injection, the treated arm was fixed with a plaster cast and progressively lengthened over 14 days. The cast was maintained for 30 days. Assessments of elbow extension, MRC, Mallet Scale and NHPT were made at baseline, 3, 6 and 12 months.

RESULTS

After BoNT-A injection, children had significant improvement of active elbow extension (15.5 degrees +/- 17.1 at 12 months after injection, compared with 42.0 degrees +/- 10.4 at baseline; p < 0.001). NPHT scores improved significantly over the 12 months (51.1 +/- 21.8 seconds compared with 56.7 +/- 19.3 seconds at baseline, p < 0.01). MRC and Mallet scale scores of the paretic muscles were unchanged.

CONCLUSION

The children showed a reduction in muscular contracture and improvements of the arm position and elbow extension. The data support the use of BoNT-A and plaster casting as an adjunct to physical therapy, in the treatment of children with mild UBPP.

Non-surgical management of ankle contracture following acquired brain injury

BACKGROUND AND PURPOSE

The purpose of this study was to document the outcome of non-surgical management of equinovarus ankle contracture in a cohort of patients with acquired brain injury admitted to a specialist Neurosurgical Rehabilitation Unit.

METHODS

This prospective descriptive study examined all patients with a new diagnosis of moderate to severe acquired brain injury (Glasgow Coma Scale score </=12) admitted for rehabilitation over a 1 year period. Ankle dorsiflexion range and plantarflexor/invertor muscle activity were evaluated weekly during the period of hospitalization. Contracture was defined as maximal passive range of motion </= 0 degrees dorsiflexion, with the knee extended, on a minimum of two measurement occasions. Patients were retrospectively allocated to one of four treatment outcome categories according to ankle dorsiflexion range, type of intervention required and response to treatment.

RESULTS

Ankle contracture was identified in 40 of the 105 patients studied. Contracture resolved with a standard physiotherapy treatment programme, including prolonged weight-bearing stretches and motor re-education, in 23 patients. Contracture persisted or worsened in 17 of 40 cases, all of whom exhibited dystonic muscle overactivity producing sustained equinovarus posturing. Ten of 17 cases required serial plaster casting (+/- injection of botulinum toxin type A) in order to achieve a functional range of ankle motion. Remediation of ankle contracture was not considered a priority in the remaining seven patients due to the severity of their overall disability.

CONCLUSION

The incidence of ankle contracture identified in this population was considerably less than previously reported. Reduced dorsiflexion range was remediated with standard physiotherapy treatment in over half of the cases. Additional treatment with serial casting +/- botulinum toxin type-A injection was required to correct persistent or worsening contracture in one quarter of cases. Dystonic extensor muscle overactivity was a major contributor to persistent or progressive ankle contracture.

Motor impairment rehabilitation post acquired brain injury

OBJECTIVE

We sought to investigate the efficacy of treatment strategies used to manage motor impairments following acquired brain injury (ABI) in order to provide guidance for clinical practice based on the best available evidence.

METHODS AND MAIN OUTCOMES

A systematic review of the literature from 1980-2005 was conducted focusing on pharmacological, non-pharmacological, and exercise interventions available for motor impairments post ABI. The efficacy of a given intervention was classified as strong (supported by two or more randomized controlled trials (RCTs)), moderate (supported by a single RCT), or limited (supported by other types of studies in the absence of RCTs).

RESULTS

Thirty-six studies examining a variety of treatment approaches for motor impairments and activity limitations following ABI were evaluated. The majority of interventions are only supported by limited evidence. However, there is strong evidence that serial casting does reduce ankle plantar contractures due to spasticity of cerebral origin, and strong evidence also suggests that partial body weight supported gait training does not provide any added benefit over conventional gait training. There is also moderate evidence to support the use of functional fine motor control retraining to improve motor coordination, tizanidine for upper and lower extremity spasticity, and specific sit-to-stand training to improve functional ability. There is also moderate evidence that casting alone is as effective as casting and Botulinum toxin injections for plantar contractures.

CONCLUSIONS

Although there are a variety of treatment strategies to manage motor impairments and activity limitations following ABI, most are only supported by limited evidence pointing to the need for studies of improved methodological quality in this area.

Análise da relação entre flexibilidade e rigidez passiva dos isquiotibiais

INTRODUÇÃO: Rigidez e flexibilidade são propriedades musculares freqüentemente consideradas como sinônimas na literatura, apesar de apresentarem diferenças com relação as suas definições. OBJETIVO: Investigar a contribuição da medida de flexibilidade dos isquiotibiais para a rigidez passiva deste grupo muscular. MÉTODOS: A rigidez e a flexibilidade foram avaliadas em 33 indivíduos saudáveis. Um dinamômetro isocinético registrava o torque passivo oferecido pelos isquiotibiais durante a extensão passiva do joelho, à velocidade de 5º/s. Durante os testes, foi feita a monitoração da atividade muscular para garantir silêncio eletromiográfico. A inclinação da reta torque x ângulo foi utilizada para determinar a rigidez total dos isquiotibiais. A amplitude de teste foi dividida em três porções para calcular a rigidez do 1º, 2º e 3º terços do movimento angular. A flexibilidade foi avaliada através do ângulo articular do joelho em que o movimento da alavanca foi interrompido pelo examinador ao perceber resistência à movimentação adicional e o participante relatar sensação de desconforto pelo alongamento dos isquiotibiais. Como tratamento estatístico, foram utilizadas análises de regressão simples. RESULTADOS: Análises de regressão demonstraram valores de correlação r = -0,48 (R² = 0,23; p = 0,005), r = -0,54 (R² = 0,29; p = 0,001), r = -0,46 (R² = 0,21; p = 0,007) e r = -0,45 (R² = 0,20; p = 0,008) entre flexibilidade e rigidez passiva total, 1º, 2º e 3º terços, respectivamente. CONCLUSÃO: Apesar de as associações entre as variáveis terem sido significativas, uma percentagem pequena da variabilidade da medida de rigidez passiva pode ser explicada pela flexibilidade. Conclui-se que essas propriedades não são sinônimas e devem ser analisadas de forma independente.

Intrinsic risk factors for the development of achilles tendon overuse injury: a prospective study

BACKGROUND

Although Achilles tendon overuse injuries occur commonly, our understanding of the pathologic changes and the factors that predispose athletes to them is limited.

PURPOSE

To identify measurable intrinsic risk factors for Achilles tendon overuse injuries.

STUDY DESIGN

Cohort study (prognosis); Level of evidence, 2.

METHODS

Sixty-nine male officer cadets followed the same 6-week basic military training. Before this training, each subject was evaluated for anthropometrical characteristics, isokinetic ankle muscle strength, ankle joint range of motion, Achilles tendon stiffness, explosive strength, and leisure and sports activity. During military training, Achilles tendon overuse injuries were registered and diagnosed by the same medical doctor. To identify the intrinsic risk factors, a multivariate analysis with the use of stepwise logistic regression was performed. The sensitivity, specificity, and cutoff values of the risk factors were evaluated by receiver operating characteristic curve analysis.

RESULTS

Ten of the 69 male recruits (14.5%) sustained an Achilles tendon overuse injury diagnosed on the basis of medical history and clinical examination. Analysis revealed that male recruits with lower plantar flexor strength and increased dorsiflexion excursion were at a greater risk of Achilles tendon overuse injury. The cutoff value of the plantar flexor strength at 85% sensitivity was 50.0 N.m, with a 4.5% specificity; the cutoff value of the dorsiflexion range of motion at 85% sensitivity was 9.0 degrees , with 24.2% specificity.

CONCLUSIONS

The strength of the plantar flexors and amount of dorsiflexion excursion were identified as significant predictors of an Achilles tendon overuse injury. A plantar flexor strength lower than 50.0 N.m and dorsiflexion range of motion higher than 9.0 degrees were possible thresholds for developing an Achilles tendon overuse injury.

Rehabilitation interventions for vegetative and minimally conscious patients

Brain injury rehabilitation is a complex and challenging task for all members of the multidisciplinary team. Medical advances have allowed more severely impaired patients to survive and consequently the number of patients in the vegetative and minimally conscious states have proportionately increased. Thus, the need for evidence-based practice and further research demonstrating the effects of specific rehabilitation interventions is required. This article reviews the current research and consensus on rehabilitation for patients in the vegetative and minimally conscious states.

Incidence of ankle contracture after moderate to severe acquired brain injury

OBJECTIVE

To examine an adult population undergoing rehabilitation after brain injury to determine the incidence of ankle contracture and factors contributing to the development of this deformity.

DESIGN

Descriptive study

SETTING

Specialist inpatient neurosurgical rehabilitation unit in Australia.

PARTICIPANTS

Patients (N=105) admitted with a new diagnosis of moderate to severe brain injury over a 12-month period.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Maximal ankle dorsiflexion range and the presence of abnormal muscle tone affecting the lower limb(s) were evaluated at weekly intervals. Ankle contracture was defined as maximal passive range of less than 0 degrees dorsiflexion with the knee in extension. Patients were grouped into 3 muscle tone categories: normal, predominantly spastic, or predominantly dystonic. Age, sex, mechanism and severity of brain injury, time to onset of ankle contracture, total length of hospital stay, and discharge mobility status data were also recorded.

RESULTS

Muscle tone was designated as normal in 68 (64.7%), as spastic in 14 (13.3%), and as dystonic in 23 (21.9%) patients. The incidence of ankle contracture was 16.2% (17/105 cases). Ankle deformity correlated closely with muscle tone category. Of 23 cases with dystonic muscle overactivity, 17 developed contracture at some point between 1 and 16 weeks after brain injury, although no subject with normal tone or spasticity developed the deformity. There was a weak association between the severity of brain injury and development of ankle contracture.

CONCLUSIONS

The incidence of ankle contracture was much lower than previously reported. Dystonic overactivity of the plantarflexor and invertor muscles is a major predisposing factor to ankle contracture.

The Role of Therapy in Spasticity Management

A number of different therapy interventions and modalities have been utilized in spasticity management. There is significant variation in the use of these therapies, which is often due to experience that the treating clinicians have with one type or another. Given the lack of well controlled studies, it is difficult to take an evidence-based approach regarding the use of these interventions at this time. This article examines the physiologic basis for the more common therapy interventions in the management of spasticity and discusses some of the literature that may help guide the clinician in choosing among these options.
