Unravelling the complexity of muscle impairment in chronic neck pain

Exercise interventions are deemed essential for the effective management of patients with neck pain. However, there has been a lack of consensus on optimal exercise prescription, which has resulted from a paucity of studies to quantify the precise nature of muscle impairment, in people with neck pain. This masterclass will present recent research from our laboratory, which has utilized surface electromyography to investigate cervical flexor muscle impairment in patients with chronic neck pain. This research has identified deficits in the motor control of the deep and superficial cervical flexor muscles in people with chronic neck pain, characterized by a delay in onset of neck muscle contraction associated with movement of the upper limb. In addition, people with neck pain demonstrate an altered pattern of muscle activation, which is characterized by reduced deep cervical flexor muscle activity during a low load cognitive task and increased activity of the superficial cervical flexor muscles during both cognitive tasks and functional activities. The results have demonstrated the complex, multifaceted nature of cervical muscle impairment, which exists in people with a history of neck pain. In turn, this has considerable implications for the rehabilitation of muscle function in people with neck pain disorders. (C) 2004 Elsevier Ltd. All rights reserved.

Impairment in the cervical flexors: a comparison of whiplash and insidious onset neck pain patients

There has been little investigation into whether or not differences exist in the nature of physical impairment associated with neck pain of whiplash and insidious origin. This study examined the neck flexor synergy during performance of the cranio-cervical flexion test, a test targeting the action of the deep neck flexors. Seventy-five volunteer subjects participated in this study and were equally divided between Group 1, asymptomatic control subjects, Group 2, subjects with insidious onset neck pain and Group 3, subjects with neck pain following a whiplash injury. The cranio-cervical flexion test was performed in five progressive stages of increasing cranio-cervical flexion range. Subjects' performance was guided by feedback from a pressure sensor inserted behind the neck which monitored the slight flattening of the cervical lordosis which occurs with the contraction of longus colli. Myoelectric signals (EMG) were detected from the muscles during performance of the test. The results indicated that both the insidious onset neck pain and whiplash groups had higher measures of EMG signal amplitude (normalized root mean square) in the sternocleidomastoid during each stage of the test compared to the control subjects (all P

Older people with hearing impairment: A literature review of the spouse's perspective

Spouses of older people with hearing impairment frequently urge their hearing impaired partners to seek help for their hearing difficulties. Only a minority of individuals with hearing impairment are self-motivated, with the majority of clients, especially older clients, presenting at audiology clinics under the persuasion or influence of their spouse or significant other. This highlights the important role that spouses play in initiating aural rehabilitation and indicates that spouses of older people with hearing impairment may become so frustrated with their partners' hearing loss that they are often the primary reason why the hearing impaired person presents for audiological services. To date, however, the number of studies addressing the effect of hearing loss on significant others is limited. Those studies that have investigated the effect of hearing impairment on families are commonly focused on the person with the impairment and most commonly, the significant other has merely been used as a proxy to describe the perceived problems of his or her spouse. Further, there has been no systematic indepth investigation of the needs of spouses of older people with hearing impairment, including the effect of retirement and the increase in time spent together, with the majority of studies focusing primarily on younger spouses of workers affected by noise-induced hearing loss. The cumulative effect of experiencing many years of hearing difficulties with a partner may also influence the extent to which older spouses are affected by hearing impairment. The primary purpose of this article is therefore to critically review the existing literature on the effects of hearing impairment on spouses. It will also provide a rationale for the importance of this topic as a clinical issue and suggest some future directions for research in this area.

Outcomes of hearing aid fitting for older people with hearing impairment and their significant others

As hearing impairment affects communication. it seems intuitive that both the person with hearing impairment and the significant other (SO) will experience effects as a result of the impairment and subsequent rehabilitation. The present study examined the effect that hearing impairment and aural rehabilitation has on the person with hearing impairment and the SO's quality of life (QOL). Ninety-three people with hearing impairment completed a measure of hearing-specific QOL (Hearing Handicap Inventory for the Elderly) and health-related QOL (Short Form-36), while 78 SOs completed a modified version of the Quantified Denver Scale and the Short Form-36. prior to and 3 months following hearing aid fitting. The results emphasize the significant impact of hearing impairment on both the person with hearing impairment and the SO. The results also demonstrate the effective role that hearing aids play in reducing Such negative effects for both parties.
