The use of an eclectic approach for the treatment of low back pain: a case study.

The purposes of this case report are (1) to describe an examination approach that relates identification of an impairment to a disability and (2) to describe an eclectic treatment approach for an individual with low back pain (LBP). The individual described in this case report is an intercollegiate athlete who, because of chronic LBP, was unable to perform his sport of pole vaulting. The findings of the physical therapy examination suggested that an impairment of lumbar motion prevented the patient from assuming the spinal position necessary for pole vaulting. The goals of the treatment consisted of increasing the patient's lumbar motion to that required for pole vaulting and to have the patient pole vault without pain or stiffness. The treatment approach that was used combined procedures described by Maitland, McKenzie, and others. The rationale for the use of these procedures and their limitations are discussed.     

Direct, quantitative clinical assessment of hand function: usefulness and reproducibility

Methods of assessing functional impairment in arthritic hands include pain assessments and disability scoring scales which are subjective, variable over time and fail to take account of the patients' need to adapt to deformities. The aim of this study was to evaluate measures of functional strength and joint motion in the assessment of the rheumatoid (RA) and osteoarthritic (OA) hand. Ten control subjects, ten RA and ten OA patients were recruited for the study. All underwent pain and disability scoring and functional assessment of the hand using measures of pinch/grip strength and range of joint motion (ROM). Functional assessments including ROM analyses at interphalangeal (IP), metacarpophalangeal (MCP) and wrist joints along with pinch/grip strength clearly discriminated between patient groups (RA vs. OA MCP ROM P<0.0001), pain and disability scales were unable to. In the RA there were demonstrable relationships between ROM measurements and disability (R2=0.31) as well as disease duration (R2=0.37). Intra-patient measures of strength were robust whereas inter-patient comparisons showed variability. In conclusion, pinch/grip strength and ROM are clinically reproducible assessments that may more accurately reflect functional impairment associated with arthritis.     

Mild Cognitive Impairment and Mild Dementia: A Clinical Perspective

Mild cognitive impairment and mild dementia are common problems in the elderly. Primary care physicians are the first point of contact for most patients with these disorders and should be familiar with their diagnosis, prognosis, and management. Both mild cognitive impairment and mild dementia are characterized by objective evidence of cognitive impairment. The main distinctions between mild cognitive impairment and mild dementia are that in the latter, more than one cognitive domain is invariably involved and substantial interference with daily life is evident. The diagnosis of mild cognitive impairment and mild dementia is based mainly on the history and cognitive examination. The prognosis for mild cognitive impairment and mild dementia is an important motivation for diagnosis because in both, there is a heightened risk for further cognitive decline. The etiology of mild cognitive impairment and mild dementia can often be established through the clinical examination, although imaging and other laboratory tests may also contribute. Although Alzheimer disease is the most common cause of both, cerebrovascular disease and Lewy body disease make important contributions. Pharmacological treatments are of modest value in mild dementia due to Alzheimer disease, and there are no approved pharmacological treatments for mild cognitive impairment of any etiology. Nonetheless, new-onset cognitive impairment is a worrisome symptom to patients and families that demands answers and advice. If a patient is having difficulties managing medications, finances, or transportation independently, diagnosis and intervention are necessary to ensure the health and safety of the patient.     

Continuous passive motion improves shoulder joint integrity following stroke

OBJECTIVE: In a pilot study of patients with a first stroke and hemiparesis, we sought to determine whether treatment of the upper limb with continuous passive motion (CPM) that was device delivered would alter impairment, disability or the associated adverse symptoms of shoulder joint instability, pain and tone. DESIGN: Patients were randomly assigned to receive daily CPM treatments or participate in self-range of motion groups under the supervision of an occupational therapist. All patients received standard daily poststroke therapy for 3.5 h per day. A blinded evaluator at admission and discharge assessed patients using standardized scales of impairment, disability and adverse symptoms. SETTING: Specialized stroke unit of an acute rehabilitation hospital. SUBJECTS: Two hundred and eighty consecutive patients were screened and 35 of these with a first unilateral stroke, 13 +/- 6 days following the acute event, provided informed consent and were randomly assigned to CPM treatment or supervised group self-range exercise. MAIN MEASURES: Thirty-two completed the study and were evaluated using standardized measures for motor impairment (Fugl-Meyer, Motor Status Scale and Medical Research Council Motor Power), adverse symptoms (gleno-humeral stability, pain and tone), and disability (Functional Independence Measure). RESULTS: CPM-treated patients demonstrated positive trends towards improved shoulder joint stability (p = 0.06, confidence interval -0.03, 2.3) when compared with patients performing therapist-supervised self-range of motion. There were no significant differences in motor impairment, disability, pain or tone. CONCLUSIONS: Device-delivered continuous passive range of motion may offer an enhanced benefit for some adverse symptom reduction in the hemiplegic arm after stroke over traditional self-range of motion exercise.     

Disability evaluation and impairment rating for the person with an amputation

Impairment rating for the person with an amputation requires a total body assessment in addition to the amputated extremity. In particular, those systems essential for prosthetic wear and function, skin coverage, sensation and motor function, and proximal joint range of motion should be included. Spinal function, pain, and psychologic impairment are frequently involved as secondary issues related to the amputation. All of these systems must be assessed and a determination made whether permanent impairment is present. The final calculation of the impairment rating uses the appropriate body systems and worksheets. Most persons with an amputation will have some appropriate work restrictions applied and all will have future medical needs.     

Ophthalmic diagnoses in the ED: optic neuritis

Optic neuritis is the most common cause of decreased vision due to optic nerve dysfunction in patients who are 20 to 40 years of age. Optic neuritis, or inflammation of the optic nerve, is primarily due to idiopathic demyelination. Demyelinative lesions seen in optic neuritis are not unlike those seen in plaque associated with multiple sclerosis. In fact, acute inflammatory demyelination of the optic nerve commonly occurs as an initial manifestation of multiple sclerosis. Key features of optic neuritis include a vision loss occurring over 1 to 10 days, color vision impairment, eye pain with motility, and an afferent pupillary defect. This significant diagnosis can be challenging to an emergency physician as it is relatively infrequently observed.     

The nonstationary strain filter in elastography: Part II. Lateral and elevational decorrelation

The nonstationary evolution of the strain filter due to lateral and elevational motion of the tissue scatterers across the ultrasound beam is analyzed for the 1-D cross-correlation-based strain estimator. The effective correlation coefficient that includes the contributions due to lateral and elevational signal decorrelation is used to derate the upper bound of the signal-to-noise ratio in the elastogram (SNR_e) predicted by the ideal strain filter. In the case of an elastically homogeneous target, if the transducer is on the axis of symmetry of such target in the elevational direction, the motion of the scatterers out the imaging plane is minimized. In addition, the ultrasound beam along the elevational direction is broader, allowing scatterers to stay longer within the beam during tissue compression. Under these conditions, lateral signal decorrelation becomes the primary contributor to the nonstationary behavior of the strain filter. Both the elastographic SNR_e and the dynamic range are reduced, with an increase in lateral decorrelation. Finite element simulations and phantom experiments are presented in this paper to corroborate the theoretical strain filter. The nonstationary behavior of the strain filter is reduced by confining the tissue in the lateral direction (minimizing motion of tissue scatterers), thereby improving the quality of the elastogram.

Stiffness of the ankle joint can lead to severe loss of quality of life and impairment of gait. In most cases the loss of motion results from secondary intraarticular and extraarticular pathologies which are differentiated into soft tissue and bony pathologies. This article describes the etiology and treatment of ankle stiffness with the main focus on arthroscopic procedures.     

Benign Paroxysmal Vertigo in Childhood: A Longitudinal Study

SYNOPSIS
21 children suffering from benign paroxysmal vertigo (BPV) were submitted to complete otoneurological examination, including caloric and rotational tabyrinthine stimulation with ENG recording, and to headache provocation tests with nitroglycerin, histamine and fenfluramine. Vestibular responses were normal in all except 2 cases which presented signs of central vestibular impairment at the level of the vestibulo-cerebellar pathways. Headache provocation tests were positive in 10 out of 15 children, and in 5 cases they induced a typical vertiginous attack instead of headache.
Several children had a positive family history for migraine. Sometimes headache was associated with the vertigo attack. Sometimes other signs of a "periodic syndrome" (motion sickness, cyclic vomiting, abdominal pain) occurred at times which were unrelated to vertiginous attacks. During the follow-up period, some children responded positively to migraine treatment.
By the authors, BPV is considered a migraine equivalent or a migraine precursor, and could be due to the same pathogenetic mechanisms responsible for the migraine.     

Cervical musculoskeletal impairment in frequent intermittent headache. Part 2: subjects with concurrent headache types

A pattern of musculoskeletal impairment inclusive of upper cervical joint dysfunction, combined with restricted cervical motion and impairment in muscle function, has been shown to differentiate cervicogenic headache from migraine and tension-type headache when reported as single headaches. It was questioned whether this pattern of cervical musculoskeletal impairment could discriminate a cervicogenic headache as one type of headache in more complex situations when persons report two or more headaches. Subjects with two or more concurrent frequent intermittent headache types (n = 108) and 57 non-headache control subjects were assessed using a set of physical measures for the cervical musculoskeletal system. Discriminant and cluster analyses revealed that 36 subjects had the pattern of musculoskeletal impairment consistent with cervicogenic headache. Isolated features of physical impairment, e.g. range of movement (cervical extension), were not helpful in differentiating cervicogenic headache. There were no differences in measures of cervical musculoskeletal impairment undertaken in this study between control subjects and those classified with non-cervicogenic headaches.     

Multiple motion encoding in phase-contrast MRI: A general theory and application to elastography imaging

While MRI allows to encode the motion of tissue in the magnetization’s phase, it remains yet a challenge to obtain high fidelity motion images due to wraps in the phase for high encoding efficiencies. Therefore, we propose an optimal multiple motion encoding method (OMME) and exemplify it in Magnetic Resonance Elastography (MRE) data. OMME is formulated as a non-convex least-squares problem for the motion using an arbitrary number of phase-contrast measurements with different motion encoding gradients (MEGs). The mathematical properties of OMME are proved in terms of standard deviation and dynamic range of the motion’s estimate for arbitrary MEGs combination which are confirmed using synthetically generated data. OMME’s performance is assessed on MRE data from in vivo human brain experiments and compared to dual encoding strategies. The unwrapped images are further used to reconstruct stiffness maps and compared to the ones obtained using conventional unwrapping methods. OMME allowed to successfully combine several MRE phase images with different MEGs, outperforming dual encoding strategies in either motion-to-noise ratio (MNR) or number of successfully reconstructed voxels with good noise stability. This lead to stiffness maps with greater resolution of details than obtained with conventional unwrapping methods. The proposed OMME method allows for a flexible and noise robust increase in the dynamic range and thus provides wrap-free phase images with high MNR. In MRE, the method may be especially suitable when high resolution images with high MNR are needed.     

Chronic pain and functional impairment: assessing beliefs about their relationship

Many chronic pain patients believe that they cannot function normally because of their pain. The Pain and Impairment Relationship Scale (PAIRS) was developed to assess the extent to which chronic pain patients endorse this belief, and the relationship of this belief to functional impairment, measured both subjectively and objectively. The PAIRS was administered to 56 patients in a chronic pain treatment program. The PAIRS demonstrated adequate internal consistency and it correlated significantly with another measure of the cognitive component of chronic pain syndrome, the Cognitive Errors Questionnaire--Low Back Scale. The PAIRS accounted for a significant proportion of variance in several measures of impairment (including the Sickness Impact Profile, restrictions in range of motion, and statements of limitation during a standardized exercise routine) beyond that accounted for solely by subjective pain estimate in multiple regression analyses. It appears that the belief that pain necessarily implies disability is associated with actual impairment, independent of the actual contribution of reported pain.     

Workshop on personal motion technologies for healthy independent living: executive summary

The objective of the June 2010 "Workshop on Personal Motions Technologies for Healthy Independent Living" was to discuss personal motion technologies that might enable older adults and individuals with disability to live independently for longer periods. The 60 participants included clinicians, academic researchers, engineers, patient advocates, caregivers, members of the public, and federal representatives. The workshop was divided into 6 sessions that addressed the following: (1) use of technologies in identifying early indicators of disease or adverse events; (2) monitoring daily activities; (3) coping with impairment; (4) managing mild cognitive impairment; (5) rehabilitation and exercise in the home; and (6) caregiver support. Presentations and discussion focused on clinical needs, the health impact of addressing those needs, state-of-the-art technologies, and challenges to adoption of those technologies. Conclusions included the following: (1) Involvement of end-users in research and development will increase the likelihood that technologies will be adopted. (2) Integration of differing types of technology into a system that includes clinical measures is required for independent living. (3) Seniors are willing to sacrifice some privacy for an effective technology that keeps them in their homes as long as they control who receives their data. (4) Multilevel and multiscale models are needed to understand motion in the context of the environment and to design effective systems.     

Prevention and management of limb contractures in neuromuscular diseases

Limb contractures are a common impairment in neuromuscular diseases. They contribute to increased disability from decreased motor performance, mobility limitations, reduced functional range of motion, loss of function for activities of daily living, and increased pain. The pathogenesis of contractures is multifactorial. Myopathic conditions are associated with more severe limb contractures compared with neuropathic disorders. Although the evidence supporting the efficacy of multiple interventions to improve range of motion in neuromuscular diseases in a sustained manner is lacking, there are generally accepted principles with regard to splinting, bracing, stretching, and surgery that help minimize the impact or disability from contractures.     

Robotic neurorehabilitation: a computational motor learning perspective

Conventional neurorehabilitation appears to have little impact on impairment over and above that of spontaneous biological recovery. Robotic neurorehabilitation has the potential for a greater impact on impairment due to easy deployment, its applicability across of a wide range of motor impairment, its high measurement reliability, and the capacity to deliver high dosage and high intensity training protocols.     

Sensory impairment in older adults: Part 1: Hearing loss

Preserving older adults' sense of hearing and helping them to maintain communication in the face of changes that occur with age are areas of concern for nurses. In addition to reviewing the types of hearing impairment, this article emphasizes assessment strategies and interventions that nurses can use across settings. This is Part 1 of a two-part article on sensory impairment in older adults; in the November 2006 issue, Part 2 will address visual impairment in this population.     

Alzheimer's disease: making the diagnosis

Alzheimer's disease accounts for about 60 percent of dementia cases. Misdiagnosis of the treatable dementias can have devastating results. Pseudodementia accompanying major depression and chronic cognitive dysfunction due to psychoactive drugs are among the most commonly missed diagnoses. Although cortical atrophy is regularly found on computed tomographic scans in Alzheimer's disease, it is not necessarily diagnostic. A relatively distinct onset of cognitive impairment is not characteristic of Alzheimer's disease.     

Self-rated disability,fear-avoidance beliefs,nonorganic pain behaviors are important mediators of ranges of active motion in chronic whiplash patients

Abstract

Purpose: The influence of self-rated disability and fear-avoidance beliefs on whiplash sufferers in their performance of active ranges of motion has not been studied well. We undertook a cross-sectional study to determine this. Methods: Chronic whiplash subjects completed a standard clinical examination. They completed the Neck Disability Index (NDI), the Tampa Scale for Kinesiophobia (TSK) and pain visual analog scale (VAS). Active ranges of motion (goniometer) and cervical nonorganic simulation signs (C-NOSS) were obtained by the examiner. Univariate and multivariable analyses were conducted on these scores. Results: Sixty-four subjects (37 female) with a mean age of 41.4 (SD 16.1) years completed all scores. NDI, pain VAS and C-NOSS correlated significantly with ROM. In a multivariable model, only the NDI score contributed significantly to the variance of the ROM scores (14%). Conclusion: As chronic whiplash sufferers perform ROM in a clinical examination, these ranges are importantly influenced by their self-perceived disability. Cervical nonorganic simulation signs can be helpful in distinguishing high from very high levels of disability and motion restriction. The lack of correlation with the TSK may present a challenge to the Fear Avoidance Model in whiplash.

• Implications for Rehabilitation

• Self-ratings of disability in chronic whiplash sufferers are influenced by their fear-avoidance beliefs.

• While self-ratings of disability are known to predict chronicity of whiplash, there is less known about how these ratings affect impairment assessment during recovery.

• This study shows that self-ratings of disability influence the presentation of impairment by chronic whiplash sufferers with respect to their ranges of neck motion.

• Signs of nonorganic behavior also influence ranges of motion and self-ratings of disability.

• These findings should be incorporated into the interpretation of impairment findings in chronic whiplash sufferers in order to improve management.

     

Ellenbogenverletzungen und Relevanz funktioneller Defizite

Injuries of the elbow joint are rather uncommon among trauma patients. However, their complex injury pattern is often severe and frequently associated with a detrimental therapeutic result. Immobilization of the elbow joint should be restricted to a minimum in order to avoid post-traumatic contracture, since surgical treatment modalities for residual impairment of motion (arthrolysis) are limited. A close collaboration between physicians and physical therapists is key to ensuring the most efficient treatment result.
