The consequence of head-loading on the neuro-musculoskeletal health of the ILembe District youth of KwaZulu-Natal.

Background: Head-loading, as a mode of transporting food, water and firewood, is a longstanding tradition assigned to female South African youth and has been associated with adverse health consequences. Objectives: This study determined the impact of head-loading on the neuromusculoskeletal health and proprioception of female South African youth. Method: This study comprised a counterbalanced, within-subject, single-factor experimental design which compared the changes that occurred when the same independent variable (head-loading) within two homogenous groups was measured in terms of the dependent variables (outcomes: neuromusculoskeletal pain and proprioception) at two time periods, before and after the introduction of the independent variable. A cohort of South African female youth (n = 100), aged 9-17 years, voluntarily partook in the study. The participants were randomly distributed into an experimental (n = 50) and a control (n = 50) group. The experimental group stood in a head-loaded state with their respective habitual head-load mass. Their proprioception measurements were compared during their unloaded versus loaded states, with the proprioceptive measurements including the total proprioception index, the anterior-posterior (front-back) index and the medial-lateral (side-to-side) index. Participants furthermore completed a head-loading health-related questionnaire. Results: Participants had a mean age of 12.3 ± 2.5 years, body mass of 44.4 ± 13.7 kg, stature of 145 ± 10 cm and a head-load mass of 8.0 ± 2.5 kg. Participants had poorer medial-lateral proprioception during head-loading as compared to their unloaded state (1.4 ± 0.8 as compared to 1.6 ± 0.9) (p < 0.05). Most youth (96%) experienced neuromusculoskeletal pain in their cervical vertebrae (40.9%), shoulders (27.3%), lumbar vertebrae (10.7%), arms (8.3%), legs (8.3%), knees (1.9%), fingers (1.5%), toes (0.5%) and thoracic vertebrae (0.5%) (χ2: p < 0.05). Conclusion: Head-loading adversely affects the medial-lateral proprioception and neuromusculoskeletal health of participants. Contribution: The findings of this study confirms that head-loading produces musculoskeletal pain.

The growth patterns of the medical technology profession in South Africa.

BACKGROUND: Constant appraisal of healthcare workforce trends is vital; this measure determines the adequacy of the workforce in meeting its society's healthcare demands. This includes determining the number of the incoming workforce (students, interns) and the active or practising workforce relevant registries. OBJECTIVE: This study aimed to examine patterns of workforce growth in the medical technology profession (students, interns and practitioners) from 2008 to 2018 in South Africa. METHODS: Student, intern and practitioner medical technology registries, from the 2012/2013, 2016/2017 and 2017/2018 Health Professions Council of South Africa (HPCSA) annual reports, were analysed. The number of National Health Laboratory Service and private laboratory posts were secured from the National Health Laboratory Service plan performance report. A comparison between the total number of South African medical technology (private and public) posts occupied versus the HPCSA practitioner 2016 register was completed, to determine the saturation status. RESULTS: Annual student, intern, and practitioner registries indicated a mean growth of 6.8%, 28.9%, and 0.7% from 2008 to 2018. The transition of interns to practitioners is progressively dwindling (2015-2018). The practitioner register showed a 1.2% decline in registration from 2013 until 2018. In 2016, only 55.9% of the HPCSA registered medical technologists were employed (p < 0.001). CONCLUSION: There are more medical technologists than available public and private sector posts. The progressively growing student register compared to the dwindling practitioner register indicates attrition in the profession. An investigation identifying the reasons why graduates neglect to register as practising medical technologists should be undertaken.

Altered cervical posture kinematics imposed by heavy school backpack loading: A literature synopsis (2009-2019).

BACKGROUND: Habitual school backpack carriage causes neuro-musculoskeletal vertebral, shoulder and hand pain; deviated posture compromised cardiopulmonary function and proprioception. OBJECTIVE: Present a novel literature summary of the influence of backpack carriage associated with deviated cervical posture and compromised pulmonary function. METHOD: An electronic literature appraisal adopting the Preferred Reporting Items for Systematic Reviews, using Google Scholar, Science Direct, EMBASE, AMED, OVID, PubMed and Sabinet search engines, was instituted during 2009-2019. Key search words: schoolbag, backpack, carriage, cervical posture and children. The quality of the studies was assessed using the Downs and Black Appraisal Scale. RESULTS: 583 records were initially identified which was reduced to 14 experimental and observational studies. A total of 1061 participants were included across the 14 studies, with an average age of 11.5 ± 1.3 years, body mass of 37.8 ± 6.6 kilograms (kg), height of 1.41 ± 0.05 meters (m), backpack mass of 5.2 ± 0.9 kg and percentage backpack mass to child's body mass of 13.75%. The studies mean rating according to the Downs and Black Appraisal Scale was 76.3%. The average craniovertebral angle (CVA) was 53.9° ± 14.6° whilst standing without carrying a backpack was reduced to 50.4° ± 16.4° when loaded (p < 0.05). Backpack loads carried varied from 5% - 30% of the participant's body mass that produced a mean CVA decline of 3.5°. CONCLUSION: Backpack carriage alters cervical posture, resulting in smaller CVA and compromised pulmonary function. There is no consensus of the precise backpack mass that initiates postural changes. Girls' posture begin changes when carrying lighter backpacks as compared to boys of the same age strata.

Ergonomic Principles as an Adjunct to the Profession of Biokinetics.

Work-related injuries date back to antiquity. Attempts to resolve these work-related challenges have, inter alia, led to the establishment of the professions of Ergonomics, Occupational Therapy, Physiotherapy, Occupational Hygiene, and Biokinetics. The objective of this article is to illustrate the value of Ergonomic principles as an adjunct to the profession of Biokinetics. Insofar as Ergonomics addresses the physical and environmental risks which predispose and precipitate injuries, the profession of Ergonomics is primarily concerned with the practice of eradicating work-related challenges that impede human-machine interfacing, and which adversely influence work productivity and employee health. While Occupational Therapy and Biokinetics, by rehabilitating work-related injuries, assist in improving working conditions, little is known about the exact interface between the professions of Ergonomics and Biokinetics. The Google Scholar database was consulted in order to determine the relationship between Ergonomics and Biokinetics. The key words used were ergonomics and biokinetics and lead to the identification of 545 records, none of which pertained to the aforementioned subject. A subsequent search was conducted using the key words work-related musculoskeletal injuries and biokinetics. This search identified 925 records, the number of which were reduced to 42 (4.76%) after the exclusion of patents (n = 24), citations (n = 3), and nonbiokinetic work-related injury research (n = 856). Given that many work-related injuries are managed through the use of biokinetic rehabilitation, knowledge of the physical ergonomic risk factors at play will afford biokineticists an enhanced understanding of the etiology of work-related injuries, thereby helping to improve the vigor of the rehabilitation.

The health benefits of exercise therapy for patients with Down syndrome: A systematic review.

BACKGROUND: Many patients with Down syndrome (PWDS) have poor cardiometabolic risk profiles, aerobic capacities and weak hypotonic muscles, primarily because of physical inactivity and poor diet. OBJECTIVES: This study discusses the benefits of exercise therapy on body composition, aerobic capacity, muscle strength, proprioception and cardiometabolic profiles of PWDS. METHODS: A literature review using the Crossref metadatabase, following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), focusing on the period 2007-2018, was undertaken. Each record was judged adopting the modified Downs and Black Appraisal Scale. The literature investigation identified 15 701 records. Records were excluded if they were published before 2007, pertained to the impact of exercise on intellectual disabilities beyond Down syndrome or the impact of medical, pharmaceutical, nutrition and psychological interventions among PWDS and were published in languages besides English. Nineteen articles were synthesised into this commentary. RESULTS: PWDS have a heightened cardiometabolic risk profile and high oxidative stress associated with elevated insulin resistance, poor insulin sensitivity, atherosclerosis and hypertension. PWDS have low aerobic capacity (VO2max), peak heart rates, muscle strength, agility and balance. Regular physical activity is beneficial to improve their VO2max and muscle strength. Moreover, regular physical activity reduces lipid peroxidation and arterial cell wall damage, the pathogenesis of atheroma is limited. CONCLUSION: Exercise therapy compliance seems to have a positive impact on the cardiometabolic risk profile, muscle strength and aerobic work capacity of PWDS. Nonetheless, additional vigorous experimental investigations are necessary to better understand the effect of exercise therapy on the aerobic, strength, proprioception and cardiometabolic risk profile of PWDS.

Are There Sufficient Number of Exercise Therapists in South Africa In Order To Equitably Manage the Noncommunicable Disease Epidemic?

The mortality of South African noncommunicable diseases (NCDs) is rising. One of its primary contributors is physical inactivity. Therefore, South African National Health Plan included exercise therapy as part of their strategy to inhibit the NCDs upsurge. This study aimed to determine whether the number of South African exercise therapists is sufficient to equitably manage this NCD epidemic. The 2013 and 2017 Health Professions Council of South Africa reports identified the number of physiotherapists, biokineticists, and their respective students-in-training. In 2012, 10,623,820 people were identified with NCDs; however, South African Department of Health only treated 6,058,186 patients (57.0%) ( p < .05). South African Health Review has estimated a 28.7% increase in the number of NCDs patients treated from 2012 (6,058,186) to 2025 (7,799,770) ( p < .05). The average yearly growth of practicing physiotherapists (3.4%) and the physiotherapy student-in-training (2.2%) is inequitable to manage this NCD epidemic. In 2012, the extrapolated physiotherapist-to-NCD patient ratio was 1:5667. The South African Department of Health should consider including biokineticists to aid in the management of the NCD epidemic.

The benefits of hydrotherapy to patients with spinal cord injuries.

BACKGROUND: Many patients with spinal cord injury (PWSCI) lead sedentary lifestyles, experiencing poor quality of life and medical challenges. PWSCI don't like to participate in land-based-exercises because it's tedious to perform the same exercises, decreasing their rehabilitative compliance and negatively impacting their well-being. An alternative exercise environment and exercises may alleviate boredom, enhancing compliance. OBJECTIVES: Discuss the benefits of hydrotherapy to PWSCI concerning underwater gait-kinematics, thermoregulatory and cardiovascular responses and spasticity. METHODOLOGY: A literature surveillance was conducted between 1998 and 2017, through the Crossref meta-database and Google Scholar, according to the PRISMA procedures. Key search words were water-therapy, aquatic-therapy, hydrotherapy, spinal cord injury, rehabilitation, human, kinematics, underwater gait, cardiorespiratory, thermoregulation and spasticity. The quality of each paper was evaluated using a modified Downs and Black Appraisal Scale. The participants were records pertaining to PWSCI and hydrotherapy. The outcomes of interest were: hydrotherapy interventions, the impact of hydrotherapy on gait-kinematics, thermoregulation during water submersion and cardiorespiratory function of PWSCI. Omitted records included: non-English publications from before 1998 or unrelated to hydrotherapy and PWSCI. The record screening admissibility was performed as follows: the title screen, the abstract screen and the full text screen. RESULTS: Literature search identified 1080 records. Upon application of the exclusion criteria, 92 titles, 29 abstracts and 17 full text records were eligible. Only 15 records were selected to be included in this clinical commentary. Evidence shows a paucity of randomised control trials (RCT) conducted in this field. CONCLUSION: Hydrotherapy improves PWSCI underwater gait-kinematics, cardiorespiratory and thermoregulatory responses and reduces spasticity.

The health benefits and constraints of exercise therapy for wheelchair users: A clinical commentary.

BACKGROUND: There are approximately 1 billion people living with chronic lower limb disability, many of whom are wheelchair users. OBJECTIVES: Review cardiometabolic and neuromuscular risk profiles of wheelchair users, benefits of regular exercise and the causes of neuromuscular upper limb and hip injuries that hinder regular adherence. METHOD: Literature published between 2013 and 2017 was adopted according to the standard practices for systematic reviews (PRISMA) through Crossref Metadata and Google Scholar searches. Individual paper quality was evaluated using a modified Downs and Black Appraisal Scale. RESULTS: The literature search identified 16 600 papers which were excluded if they were non-English, non-peer-reviewed or published before 2013. Finally, 25 papers were accepted, indicating that sedentary wheelchair users have poor cardiometabolic risk profiles (PCMRP) because of a lack of physical activity, limiting their quality of life, characterised by low self-esteem, social isolation and depression. Their predominant mode of physical activity is through upper limb exercises, which not only improves their cardiometabolic risk profiles but also precipitates neuromuscular upper limb overuse injuries. The primary cause of upper limb injuries was attributed to poor wheelchair propulsion related to incorrect chair setup and poor cardiorespiratory fitness. CONCLUSION: Wheelchair users have a high body mass index, body fat percentage and serum lipid, cholesterol and blood glucose concentrations. Empirical investigations illustrate exercise improves their PCMRP and cardiorespiratory fitness levels. Although literature encourages regular exercise, none discusses the need to individualise chair setup in order to eliminate wheelchair pathomechanics and upper limb neuromuscular injuries. Wheelchair users must be encouraged to consult a biokineticist or physiotherapist to review their wheelchair setup so as to eliminate possible incorrect manual wheelchair propulsion biomechanics and consequent overuse injuries.
