Thus , WIs were seldom design ed to improve return-to-work .
Overall , there was low quality evidence that showed no significant differences between WIs and no intervention for pain prevalence or severity .
If present , significant results in favour of WIs were not sustained across follow-up times .
Overall , this review found low quality evidence that neither supported nor refuted the benefits of any specific WI for pain relief and moderate quality evidence that a multiple-component intervention reduced sickness absence in the intermediate-term , which was not sustained over time .

Acute Treatment of Whiplash Neck Sprain Injuries: A Randomized Trial of Treatment During the First 14 Days After a Car Accident
Study Design . A single‐blinded , r and omized treatment study with a follow‐up period of 6 months . Objective . To study the long‐term consequences of whiplash neck sprain injuries in patients treated with two different regimes during the first 14 days after the car accident . Patients in the first group were encouraged to act as usual , i.e. , continue to engage in their normal , pre‐injury activities ; that group was compared with another group of patients who were given time off from work and who were immobilized using a soft neck collar . The end point of the comparison was the evaluation of subjective symptoms 6 months after the accident . Summary of Background Data . Few r and omized treatment studies have been performed to evaluate the clinical outcome for patients with neck sprain . Method . Patients who participated in the study were recruited from the Emergency Clinic at the University Hospital in Trondheim , Norway . The study group included 201 patients ( 47 % of the study group ) with neck sprain that result ed from a car accident .  Neck and shoulder movements and subjective symptoms , which were assessed using several different measurements , were assessed during the follow‐up period . Results . There was a significant reduction of symptoms from the time of intake to 24 weeks after the treatment period in both groups . There was a significantly better outcome for the act‐as‐usual group in terms of subjective symptoms , including pain localization , pain during daily activities , neck stiffness , memory , and concentration , and in terms of visual analog scale measurements of neck pain and headache . Conclusions . The outcome was better for patients who were encouraged to continue engaging in their normal , pre‐injury activities as usual than for patients who took sick leave from work and who were immobilized during the first 14 days after the neck sprain injury
