Mobile phone usage among Nigerians: Risk factors for musculoskeletal injuries and preventive strategies.

Aims: The increase in the usage of hand-held devices (HHDs) and smartphones (SPs), especially in Nigeria has resulted in an upsurge of musculoskeletal complaints. The aim of this study was to determine the incidence and risk factors for musculoskeletal injuries due to mobile phone usage among Nigerians and the preventive strategies. Materials and Methods: This study involved 630 male and female participants above 18 years old who were purposively recruited across designated study centres in public places. The instrument used was a questionnaire specifically designed to suit the Nigerian culture and environment and developed from previously validated questionnaires. Data were exported to Statistical Computing Programming R version 4.0.5 for analysis and Chi-square was used to compare the characteristics of those who experienced injury using SPs/HHDS and those who did not. Independent variables with a 95% confidence level and P < 0.05 in the multivariate model were considered statistically significant. Results: The most common daily use of SPs/HHDS by the participants was phone calls (98.4%) followed closely by social networking (96.0%) while the occupation and educational level of the participants had statistically significant (P < 0.05) impact on musculoskeletal injuries. The type of mobile device and the time spent using these devices were also significant (P < 0.05) risk factors for injuries. Some self-treatment strategies adopted by the participants were all significantly (P < 0.05) associated with reduction of musculoskeletal discomfort. Conclusion: The occupation, educational level, the types of mobile devices and time spent using the devices were risk factors for musculoskeletal injuries.

Effects of Combined Aerobic and Stretching Exercises on the Cardiopulmonary Parameters of Premenopausal and Postmenopausal Breast Cancer Survivors.

BACKGROUND: Therapeutic approaches that will improve the reduced cardiopulmonary functions of breast cancer (BC) survivors are of optimal importance. The effects of aerobic exercise on health-related outcomes of BC survivors have been reported while there is a dearth of information on the effects of combined aerobic and stretching exercises on cardiopulmonary parameters of female BC survivors. OBJECTIVE: This study investigated the effects of combined aerobic and stretching exercises on cardiopulmonary functions of premenopausal and postmenopausal Breast cancer (BC) survivors. METHODS: Fifty-four eligible BC survivors participated in the study but four-eight completed it. They were randomly' assigned to groups A and B and each group had two subgroups; subgroup 1 (premenopausal) and subgroup 2 (postmenopausal). Group A underwent combined aerobic exercise using treadmill and stretching exercises for 12 weeks while Group B was the control group. RESULTS: Significant changes were observed in the cardiovascular parameters of participants in Groups A,,,,, (Resting systolic blood pressure (A1:p = 0.01*; A2: p = 0.01*), Resting diastolic blood pressure (A1: p = 0.01*; A2: p = 0.004*), Resting rate pressure product (A1: p 0.001*; A2: p = 0.02*). Significant changes were also observed in the pulmonary parameters of participants of Groups A(1&2) (Arterioxyhaemoglobin saturation (A,:p = 0.001*; A2:p = 0.02*), Forced vital capacity (A1:p = 0.13; A2: p = 0.05*), maximal oxygen uptake (A1:p = 0.03*; A2: p = 0.15). CONCLUSION: Combined aerobic and stretching exercises brought about significant therapeutic effects on selected cardiopulmonary parameters in female BC survivors.

Prevalence and impacts of low back pain among peasant farmers in south-west Nigeria.

OBJECTIVES: A relationship between low back pain (LBP) and poor postures has been previously established with a high prevalence observed in many occupations. This study aimed to investigate the prevalence of LBP, associated risk factors and impacts on farmers in South-West Nigeria. MATERIALS AND METHODS: Six hundred and four farmers completed a 36-item closed-ended questionnaire which was translated to Yoruba language with content validity and back translation done after-wards. The questionnaire sought information on demographic data, 12-month prevalence, severity, history, causes and management of LBP, and its impacts on farm activities and the activities of daily living. Data was analyzed using the Statistical Package for Social Sciences (SPSS) version 17. Data was summarized using descriptive statistics of mean, range, frequency, standard deviation, percentage. Chi2 and Mann-Whitney-U test were used to find association between variables. The level of significance was set at α = 0.05. RESULTS: The 12-month prevalence of LBP among the respondents was 74.4%. Low back pain was described as moderate in 53.4%. Prolonged bending (51.3%) was the most related risk factor. A consider-able proportion (65.9%) of the respondents were unable to continue some of the previously enjoyed activities. Males had significantly higher (p < 0.05) prevalence, recurrence and duration of LBP than the females. CONCLUSION: There is a high prevalence of LBP among farmers in South-West Nigeria. Age, sex and years of involvement in farming have a significant influence on the prevalence of LBP.

The morphology of the healing tendon: a comparison of the effects of intrasound therapy and therapeutic pulsed ultrasound.

BACKGROUND AND PURPOSE: This study investigated the effects of low- and high-intensity intrasound therapy (LITR and HITR) and low-intensity pulsed ultrasound (LIPUS) on the morphology of the healing tendon. METHODS: Forty-five male Sprague-Dawley albino rats, randomized into five groups, were further subdivided into groups A and B except Group 1. Groups 2-5 underwent an induced crush injury to the Achilles tendon. The groups were allocated to serve as controls (Group 1), received no treatment (Group 2), LIPUS once daily (Group 3), LITR twice daily (Group 4), and HITR twice daily (Group 5). Treatment commenced 24 hr post-injury over the first 14 days. Subgroup A animals were killed on day 15 and those in subgroup B were killed on day 31. The tendons were excised and processed for histological studies. RESULTS: LITR and HITR given twice daily caused a significant (p < 0.05) proliferation of tenoblasts in the proliferative phase and enhanced their terminal differentiation to tenocytes in the remodeling phase compared with the untreated and LIPUS-treated groups. LITR and HITR also resulted in a significant increase in the volume fraction of collagen fibers compared with LIPUS. CONCLUSION: Intrasound therapy has a better morphological effect on the healing tendon than LIPUS and may be an option to consider in the treatment of acute tendon injuries.

Incidence and pattern of injuries among adolescent basketball players in Nigeria.

BACKGROUND: Basketball is the second most popular sport in Nigeria after football and is commonly played by adolescents. Prospective studies on adolescent basketball players in Nigeria are lacking. Such studies will help to develop injury counter-measures. Hence, this study aimed at determining the incidence and pattern of injuries among adolescent basketball players in Nigeria. METHODS: A prospective observational study involving 141 adolescent basketball players (75 boys and 66 girls; with age range 15 - 18 years) who participated in the 2010 National Finals of the Nigeria Nestlé Milo Basketball Competition. Basketball-related injury data were collected by an assessor during the competition using a standardized basketball injury report form. Data were analyzed using descriptive and inferential statistics. RESULTS: A total of 32 injuries were recorded with an incidence of 22.7 injuries per 100 participants same for boys and girls. This is equivalent to 1.1 injury per match for boys and 0.9 injuries per match for girls. Jumping/landing was the most common cause of injury (28.1%, N = 9). Most of the injuries were at the lower extremities (75%, N = 24); with majority at the knee joint (40.6%, N = 13). Ligament sprain was the most common types of injury. The pattern of injuries among boys did not significantly differ from that of girls (P > 0.05). Most injuries (N = 13, 41%) occurred in the offensive half of the court and cryotherapy was the most frequently used treatment modality. CONCLUSION: The overall incidence of match injury among adolescent amateur basketball players during a national competition in Nigeria was 22.7 injuries per 100 participants; equivalence of 1.0 injury per match. The pattern of injuries was similar in both genders and consistent with what has been previously reported in literature for adolescent basketball players. Exercise-based injury prevention programmes aimed at improving core strength and neuromuscular control at the lower limbs may help reduce the incidence of injuries.
