Children now have greater accessibility to computers both at school and at home. Recent studies suggest that with this increased exposure, there are associated musculoskeletal disorders (MSDs) in both school-aged children and adults. Objectives: To assess the posture assumed by secondary school students during computer use and its impact on the occurrence and severity of reported musculoskeletal discomforts. Methods: Posture assumed during normal computer class, occurrence of discomforts, body parts involved and the intensity of discomforts were evaluated in 235 school aged children using Rapid Upper Limb Assessment (RULA) scale, Body Discomfort Chart (BDC) and Visual Analogue Scale (VAS) before and after normal computer class. Inferential statistics of t-test and chi-square were used to determine significance difference between variables, with level of significant set at p < 0.05. Results: None of the participants demonstrated acceptable posture. Computer use produced significant discomforts on the neck, shoulder and low back. There was a significant relationship between participants height and posture assumed. Two hundred and eleven (89.8%) participants reported discomforts/pain during the use of computer. Weight and height were contributory factors to the occurrence of musculoskeletal discomfort/pain (p < 0.05) in some of the body parts studied. Conclusion: Musculoskeletal discomfort was found to be a problem among the school-aged children during computer use. Weight and height were implicated as factors that influenced the form of posture and the nature of the reported discomfort. Creating awareness about the knowledge of ergonomics and safety for promotion of good posture was therefore recommended.

Chronic Low Back Pain (CLBP) presents with enormous consequence on the general performance of the sufferer, exerting a huge cost on the individual, the family and the society. Dance therapy is a relatively new approach in the management of low back pain. This study was therefore designed to investigate the effect of dance therapy on pain, functional disability and quality of life in patients with chronic low back pain. Thirty subjects diagnosed with non-specific CLBP particpated in the study. They were randomly divided into 2 groups, A and B, each comprising 15 subjects. In addition to conventional physiotherapy programme given to both groups, subjects in Group A also received aerobic dance, which comprised a four stage protocol. The entire treatment routine was administered in a group session three times weekly consecutively for six weeks. Data as obtained in the copies of completed questionnaires (Roland Morris Diability questionnaires and Nottingham Health Profile questionnaires) and other measurements were summarized using mean, standard deviation and frequency tables. Student T-test was used to analyze the data at 95 % confidence interval. There was a statistically significant difference (p<0.05) between the pre-and post-intervention scores for pain intensity, functional disability and quality of life within the groups. There was also a statistically significant difference (p<0.05) in the mean change (pre/post intervention) scores between Group A and Group B for pain intensity, functional disability and quality of life. Also the opinions and testimonies given by participants formed part of the evidence-based data. Whereas both conventional physiotherapy and aerobic dance showed significant effects in the pre/post-intervention scores, the aerobic dance group reported more significant effect in all studied parameters of pain intensity, functional disability and quality of life.

They are also used for weight loss. The aim of this study is to produce a special exercise bike which allows for both upper and lower limbs pedalling either independently or otherwise. The manufacturing processes employed in the design involved the use of AutoCAD design suite and other production engineering processes which included material selection and acquisition, cutting, welding and drilling. The device was tested for both comfort and effectiveness for cardiac rehabilitation using the rate of heartbeat as the test parameter. A strong positive correlation was found (p<0.001; r=0.962) between the two heart rate tests. An ergonomic evaluation of the bi-modal exercise bike showed 98% suitability of the seat-pedal height with the knee height of the study population and 100% suitability of the seathandle post height with the buttock-knee length of the population. In conclusion, the goal of developing a bi-modal exercise bike that permits simultaneous upper and lower limbs pedalling was realised.

Assessment of exposure level to MSD risk factors can be an appropriate base for planning and implementing interventional ergonomic programs in the workplace. This study was designed to determine the prevalence of MSD among Road construction manual workers and also to assess their level of exposure to MSD risk factors. Method: This was a cross-sectional analytical descriptive study involving 160 manual workers of a construction company. The participants were required to complete a closed ended structured questionnaire which was used to collect the information on the prevalence of MSD. The level of exposure to risks of MSD was assessed using Quick exposure check (QEC). Result: All of the workers 160 (100%) reported some kind of MSD during the last 12 months. The highest prevalence was reported in the back 90.4% (145) followed by s...

When MSDs develop in occupational settings, sequel to the physical tasks involved in the performance of work and the condition of the work-environment, they are referred to as work-related musculoskeletal disorders (WMSDs). The development and prognosis of any particular MSDs are modified by multiple risk factors, which are physical, individual, and psychosocial, in nature. None of these factors act separately to cause WMSDs, rather, they interact. The goal of ergonomics is to create an ergonomically sound work-environment, with the view to reducing the occurrence of WMSDs. This is premised on adherence to effective workplace ergonomic principles (WEP). By and large, WEP is more effective when done both at the workplace and during the performance of leisure time activities. Often, WEP involves designing the workplace, with consideration for the capabilities and limitations of the workers, thus promoting good musculoskeletal health, and improving performance and productivity. For favorable outcomes, a three-tier hierarchy of controls (Engineering, Administrative, and use of Personal Protective Equipment) is widely accepted as a standard intervention strategy for reducing, eliminating, or controlling workplace hazards. Failure of this strategy will expose workers to WMSDs.

The high incidence of back pain and the popularity of shoe insoles call for a systematic review of this practice. To determine the effectiveness of shoe insoles in the prevention and treatment of non-specific back pain compared to placebo, no intervention, or other interventions. We searched the following databases: The Cochrane Back Group Trials Register and The Cochrane Central Register of Controlled Trials (CENTRAL) to March 2005, and MEDLINE, EMBASE, and CINAHL to February 2007; reviewed reference lists in review articles, guidelines and in the included trials; conducted citation tracking; contacted individuals with expertise in this domain. We included randomized controlled trials that examined the use of customized or non-customized insoles, for the prevention or treatment of back pain, compared to placebo, no intervention or other interventions. Study outcomes had to include at least one of the following: self-reported incidence or physician diagnosis of back pain; pain intensity; duration of back pain; absenteeism; functional status. Studies of insoles designed to treat limb length inequality were excluded. One review author conducted the searches and blinded the retrieved references for authors, institution and journal. Two review authors independently selected the relevant articles. Two different review authors independently assessed the methodological quality and clinical relevance and extracted the data from each trial using a standardized form. Six randomized controlled trials met inclusion criteria: Three examined prevention of back pain (2061 participants) and three examined mixed populations (256 participants) without being clear whether they were aimed at primary or secondary prevention or treatment. No treatment trials were found. There is strong evidence that the use of insoles does not prevent back pain. There is limited evidence that insoles alleviate back pain or adversely shift the pain to the lower extremities. This review largely reflects limitations of the literature, including low quality studies with heterogeneous interventions and outcome measures, poor blinding and poor reporting. There is strong evidence that insoles are not effective for the prevention of back pain. The current evidence on insoles as treatment for low-back pain does not allow any conclusions.High quality trials are required for stronger conclusions.

In this paper, we have carried out the biometry of pain in patients of knee osteoarthritis (OA). The study evaluates causes of knee pain, its severity and effects on daily activities, psychosocial life and sleep. The study population was drawn from five government hospitals in Lagos State. After initial treatment, only patients with knee pain were enlisted as subjects in the study. A standardized questionnaire was used for data collection to determine the causes of the pain, its severity and effects on the operational performance of individuals with OA. Chi-square analysis was carried out on our samples at a statistical level of significance of α = 0.05. Out of 525 questionnaires that were distributed, 431 (82.10%) were responded to. The outcomes of this study indicate that OA affects individuals of all ages and genders irrespective of their topographical locations. 242 (89.67%) women and 189 (88.97%) men were affected with higher incidence recorded within the age groups of (41-50) and (61-70) with frequency values of 62 (84.00%) and 85 (92.85%) respectively. The risk factors include overweight, occupational hazard and previous history of knee injury. Overweight 132 (91.86%), Obesity 59 (92.28%) and Extreme Obesity 5 (90.37%). Previous injury 173 (90.52) % and non-previous injury is 258 (87.78%). This work studies biometrics of OA as basis for developing a therapeutic management of knee OA, and this is to improve the patient's pain tolerance and relief of swollen knee without adverse effect.

Postural evaluation with epidemiological investigation for possible association may be appropriate for planning ergonomic programs. OBJECTIVE: To evaluate working postures and investigate associations between postural risks and prevalence of WRMDs among beverage bottling workers. METHOD: 301 beverage bottling company workers (8 workstations) participated in this survey. They were required to complete a modified standard Nordic questionnaire, and their working postures examined utilizing Rapid Entire Body Assessment (REBA). RESULTS: Postural risks ratings were high (8-10) to very high (11-15). Shoulder was the most commonly reported body part with WRMDs except at the carbonating workstations where Neck, Upper and Lower back discomforts were the most common (60.0%). The compounding workstations recorded the highest prevalence of WRMDs in all body regions except shoulder and wrist. There was a significant association between working posture and occurrence of WRMDs in at least one body part. Similarly, working posture was significantly associated with WRMDs at Neck, Upper back and Wrist. CONCLUSIONS: Working postures may be exposing beverage bottling workers to significant risk of developing WRMDs in at least one body part, more specifically, Shoulder, Neck, Upper back and Wrist. Intervention aimed at reducing postural risks is necessary.
