A systematic review of musculoskeletal disorders among dental professionals

INTERNATIONAL JOURNAL OF DENTAL HYGIENE, Issue 3 2009
MJ Hayes
Abstract:, Musculoskeletal problems have become a significant issue for the profession of dentistry and dental hygiene. This review provides a detailed examination and discussion regarding the prevalence of musculoskeletal disorders (MSD) in dental personnel and possible causative factors. All research studies or literature reviews, which have reported on the prevalence of musculoskeletal symptoms and/or potential risk factors for this problem in dentists, dental hygienists and dental students, were selected for inclusion. Our literature suggests that the prevalence of general musculoskeletal pain ranges between 64% and 93%. The most prevalent regions for pain in dentists have been shown to be the back (36.3,60.1%) and neck (19.8,85%), while the hand and wrist regions were the most prevalent regions for dental hygienists (60,69.5%). Interestingly, we found that studies on MSDs among dental and dental hygiene students are quite limited. Many risk factors have been identified, including static and awkward posture and work practices. Overall, the review suggests that musculoskeletal problems represent a significant burden for the dental profession. More research in the form of larger studies is urgently required, to help more clearly elucidate the development of this important issue for dental hygienists and dental hygiene students. [source]

Musculoskeletal problems of the neck, shoulder, and back and functional consequences in nurses

AMERICAN JOURNAL OF INDUSTRIAL MEDICINE, Issue 3 2002
Alison M. Trinkoff ScD
Abstract Background Though musculoskeletal disorders (MSDs) are highly prevalent among registered nurses (RNs), little is known about functional consequences of MSDs in nurses. Methods Data on neck, shoulder, and back MSD problems were analyzed in 1,163 working nurses (response rate,=,74%). Cases had relevant symptoms lasting at least 1 week or occurring at least monthly in the past year, with at least moderate pain intensity, on average. MSD problems with a frequency, duration, or pain intensity below the level needed to meet the case definition were defined as MSD symptoms. Those who did not meet symptom or case criteria at any body site were defined as asymptomatic. Odds of consequences (e.g., saw a doctor/provider, missed work, reduced/modified work, non-work activities, or recreation, medication use, inadequate sleep) were estimated for cases versus those with symptoms. Results We found 45.8, 35.1, and 47.0% of nurses had neck, shoulder, or back MSD problems (either at the case or symptom level), respectively, within the past year. Cases were far more likely to have seen a provider versus those with symptoms (adjusted odds ratio, aOR Neck: 4.33, 95% CI: 2.85,6.56; aOR Shoulder: 4.83, 95% CI: 3.00,7.77; aOR Back: 3.69, 95% CI: 2.47,5.49). Cases also were more likely to experience all other functional consequences. Conclusions MSD consequences are substantial and suggest opportunities for intervention. Future research will examine the impact of work organization and physical demands on MSDs. Am. J. Ind. Med. 41:170,178, 2002. © 2002 Wiley-Liss, Inc. [source]

Upper limb muscle imbalance in tennis elbow: A functional and electromyographic assessment

JOURNAL OF ORTHOPAEDIC RESEARCH, Issue 12 2007

Abstract The purpose of this study was to investigate strength, fatigability, and activity of upper limb musculature to elucidate the role of muscular imbalance in the pathophysiology of tennis elbow. Sixteen patients clinically diagnosed with tennis elbow, recruited from a university hospital upper limb orthopedic clinic, were compared with 16 control subjects with no history of upper limb musculoskeletal problem, recruited from university students and staff. Muscle strength was measured for grip, metacarpophalangeal, wrist, and shoulder on both sides. Electromyographic activity (RMS amplitude) and fatigue characteristics (median frequency slope) of five forearm and two shoulder muscles were measured during isometric contraction at 50% maximum voluntary contraction. All strength measurements showed dominance difference in C, but none in TE. In tennis elbow compared to controls, hand/wrist and shoulder strength and extensor carpi radialis (ECR) activity were reduced (p,<,0.05), while fatigue was normal. A global upper limb weakness exists in tennis elbow. This may be due to disuse and deconditioning syndrome caused by fear avoidance, and needs to be addressed in prevention and treatment. Activation imbalance among forearm muscles (reduced extensor carpi radialis activity) in tennis elbow, probably due to protective pain-related inhibition, could lead to a widespread upper limb muscle imbalance. © 2007 Orthopaedic Research Society.

Orthopaedic issues in the musculoskeletal care of adults with cerebral palsy

DEVELOPMENTAL MEDICINE & CHILD NEUROLOGY, Issue 2009
HELEN M HORSTMANN MD
Aims, Orthopaedic care of adults with cerebral palsy (CP) has not been well documented in orthopaedic literature. This paper focuses on some of the common problems which present themselves when adults with CP seek orthopaedic intervention. In particular, we review the most common orthopaedic issues which present to the Penn Neuro-Orthopaedics Program. Method, A formal review of consecutive surgeries performed by the senior author on adults with CP was previously conducted. This paper focuses on the health delivery care for the adult with orthopaedic problems related to cerebral palsy. Ninety-two percent of these patients required lower extremity surgery. Forty percent had procedures performed on the upper extremities. Results, The majority of problems seen in the Penn Neuro-Orthopaedics Program are associated with the residuals of childhood issues, particularly deformities associated with contractures. Patients are also referred for treatment of acquired musculoskeletal problems such as degenerative arthritis of the hip or knee. A combination of problems contribute most frequently to foot deformities and pain with weight-bearing, shoewear or both, most often due to equinovarus. The surgical correction of this is most often facilitated through a split anterior tibial tendon transfer. Posterior tibial transfers are rarely indicated. Residual equinus deformities contribute to a pes planus deformity. The split anterior tibial tendon transfer is usually combined with gastrocnemius-soleus recession and plantar release. Transfer of the flexor digitorum longus to the os calcis is done to augment the plantar flexor power. Rigid pes planus deformity is treated with a triple arthrodesis. Resolution of deformity allows for a good base for standing, improved ability to tolerate shoewear, and/or braces. Other recurrent or unresolved issues involve hip and knee contractures. Issues of lever arm dysfunction create problems with mechanical inefficiency. Upper extremity intervention is principally to correct contractures. Internal rotation and adductor tightness at the shoulder makes for difficult underarm hygiene and predispose a patient to a spiral fracture of the humerus. A tight flexor, pronation pattern is frequently noted through the elbow and forearm with further flexion contractures through the wrist and fingers. Lengthenings are more frequently performed than tendon transfers in the upper extremity. Arthrodesis of the wrist or on rare occasions of the metacarpal-phalangeal joints supplement the lengthenings when needed. Conclusions, The Penn Neuro-Orthopaedics Program has successfully treated adults with both residual and acquired musculoskeletal deformities. These deformities become more critical when combined with degenerative changes, a relative increase in body mass, fatigue, and weakness associated with the aging process. [source]

Adults with cerebral palsy: a survey describing problems, needs, and resources, with special emphasis on locomotion

DEVELOPMENTAL MEDICINE & CHILD NEUROLOGY, Issue 2 2001
Christina Andersson MSc PT
The purpose of this study was to describe problems and resources of adults with cerebral palsy (CP) with special emphasis on locomotion. A questionnaire concerning demographic facts, locomotion, musculoskeletal problems, and present physical activity was mailed to 363 adults with CP. Two hundred and twenty-one adults, (125 male and 96 female; mean age 36 years, range 20 to 58 years) answered the questionnaire. Seventy-seven per cent reported problems with spasticity. Eighty-four per cent lived in their own apartments, with or without home services. Twenty-four per cent worked full-time and 18% had full disability pension. Twenty-seven per cent had never been able to walk, 64% could walk with or without walking aids, 35% reported decreased walking ability, and 9% had stopped walking. Eighty per cent reported contractures and 18% had pain every day. Approximately 60% were regularly physically active, and despite their disability, 54% considered that they were not limited in their ability to move about in the community. [source]

Motivational interviewing in musculoskeletal care

MUSCULOSKELETAL CARE, Issue 4 2007
Robert Shannon BSc MSc
Abstract Motivational interviewing is a patient-centred counselling method designed to build motivation for behaviour change by resolving ambivalence. It was developed in the addictions field and has since been applied to medical and health promotion settings. This paper will provide a brief overview of the method and will discuss how it may be used in consultations for patients with musculoskeletal problems to increase engagement with treatment and to build motivation for helpful behaviour change.

Concurrent validity of the NK hand dexterity test

PHYSIOTHERAPY RESEARCH INTERNATIONAL, Issue 2 2001
Joy C MacDermid BSc, PT PhD Co-Director
Abstract Background and Purpose The present study evaluated the concurrent validity of the NK hand dexterity test (NKHDT) by use of three separate analyses: (1) the correlation between the NKHDT and a criterion comparator (Jebson's Hand Function Test (JHFT)); (2) the correlation between both dexterity tests and a patient-rated function questionnaire; and (3) the ability of subscales to differentiate between subjects with and without upper extremity pathology. Method The study population included 40 individuals with a variety of musculoskeletal problems affecting the upper extremity and 10 individuals without any history of upper extremity problems. Both dexterity tests were administered on a single occasion according to a standard protocol. Subjects also completed a rating scale which evaluated self-care, household work, work and recreation on an 0,10-point scale. Results The validity of the NKHDT was supported in all three analyses because: (1) the correlation between the NKHDT and JHFT subtests was moderate to strong (Pearson's r=0.47,0.87) and stronger when the objects were more similar in size; (2) both scales correlated to a similar extent with patient-rated function (Pearson's r=,0.34,0.67); and (3) all subscales were statistically different between subjects with and without upper extremity pathology (p<0.01). Conclusions The present study supports the use of the NKHDT as a measure of hand dexterity. Copyright © 2001 Whurr Publishers Ltd. [source]

Are psychosocial factors, risk factors for symptoms and signs of the shoulder, elbow, or hand/wrist?: A review of the epidemiological literature

AMERICAN JOURNAL OF INDUSTRIAL MEDICINE, Issue 5 2002
Paulien M. Bongers PhD
Abstract Background In 1993, an extensive review on the role of psychosocial factors in the development of musculoskeletal problems was published by Bongers et al (1993). Since then, additional reviews on this topic have been published; however, none of these focussed on upper limb problems. Methods In this systematic review, the methodological quality of all studies was assessed and levels of evidence were apriori defined. Results The large majority of the studies reported an association between at least one work-related psychosocial factor and adverse upper extremity symptoms or signs. High-perceived job stress was consistently associated with all upper extremity problems (UEP) in high and lower quality studies. Although not often studied, non-work-related stress was also consistently associated with UEP. In addition, there was some evidence for a relationship between high job demands and UEP, although the results did not meet the pre-set criterion for consistency. Conclusions High job stress and non-work-related stress reactions are consistently associated with UEP. In addition, high job demands is also in most studies associated with these disorders. Firm conclusions on the role of these factors in the etiology of UEP are not possible due to the cross-sectional nature of most studies. Am. J. Ind. Med. 41:315,342, 2002. © 2002 Wiley-Liss, Inc.
