Transcript of KIN381 - Psychosocial Factors in Injury Development

Roots Enablers Case Study 1 Case Study 3 Trunk Behavioral Responses to Stress Poor management
Inadequate rest
specific deadlines
time constraints
hostile work environment
unrealistic expectations
favoritism The Role of Psychosocial
Factors in Injury Development To study the relationship between neck pain and physical & psychosocial workplace exposures, including workplace harassment, among female and male workers. What jobs do you think psychosocial factors have the largest influence on in relation to development of injury, and how? David Kardos, Paulina Domzal, Nicole Nussle job demand
work-life balance
social interactions
physical environment What are the psychosocial factors? Decreased physical performance fatigue
decreased productivity
unsafe shortcuts Neuroticism Decreased satisfaction role
job future
job control
job content Case Study 2 anger & frustration
turnover sexual harassment
violence health care
fire fighter
assembly line Work force: Forestry workers in New Zealand surveyed to determine effects of work, rest, and recovery in accident and injury prevalence Results:
78% reported experiencing fatigue at least "sometimes" Implications:
In an industry with already very slim margins for error, impairment from fatigue represents a large risk factor for injury Solutions How can we remedy these issues? Results: Objective: 18.4% of female & 10.9% of male workers reported significant neck pain
Highly significant relationship between neck pain & unwanted sexual attention and neck pain & intimidation at work for both genders
Others include: repetitive work, sitting posture, high psychological job demands and psychological distress Potential Mechanisms: Suggested Solutions workplace programmes to reduce harassment in workplace that includes prevention of sexual harassment implement sexual harassment awareness in training effectively
provide accessible resources to report concerns/questions about harassment in the workplace (ie: anonymous hotline)
promote a physically and mentally health workplace (ie: workplace recreational sport teams)
enforce workplace intervention when workplace environment is becoming toxic
all levels of management to acknowledge importance of harassment “Factors Prolonging Disability in Work -Related Cumulative Trauma Disorders” Main Objective: Examine the three main variables that determine return to work after soft tissue disorders of the upper extremities:
i. Type of musculoskeletal disorders
ii. Ergonomic issue
iii. Psychosocial issues Method: 25 people had moderate pain symptoms from injury 25 people had severe pain from injury 23 of these 25 returned to work with modifications to their job demands and ergonomic issues. 8 Minor issues:
All returned to work Findings: Ergonomic classification does not independently predict return to work potential. Solutions: MULTIDISCIPLINARY APPROACH The General Idea: Everyone in the work place works together to help the persons recovery 15 moderate issues:
8 returned to work after case management techniques were implemented 2 major issues:
Neither returned to work Psychosocial classification is the primary factor in prolonged injury All cases with even the worst ergonomic problems, returned to work in the absence of moderate or major psychosocial issues. The therapist working with the patient must listen to the patient psychosocial concerns and acts as a support system The therapist continues with the patient even once they have improved Any fall back in the patients recovery leads to a meeting with all team members and the patient to adjust and implement a new plan. This gives the patient comfort, control and confidence. The therapist also reduces anxiety by communicating with the patient and all of the patients physicians, insurance companies and rehab specialists to assure everyone is on the right page. 2 of them had major ergonomic issues and major psychosocial issues these people did NOT return to work persistent

muscle strain indirect
pathway co-contractions
and/or sustained
contractions reasonable rest periods using research done on shift work to advantage near-miss injury events highly correlated with fatigue fatigue: long working hours, reduced sleep, compromised recovery time, intensely-paced work Impairment from fatigue and its causes need to be studied Industry awareness of causes and consequences of fatigue need to be increased psychological demands assessed to prevent hazards to workers sufficient training health & safety concerns taken seriously
