Strength training program reduces neck and shoulder pain among industrial workers .
OrthoEvidence Journal (OE Journal) - ACE Report
OE Journal. 2013;1(17):13 BMC Musculoskelet Disord. 2011 Sep 21;12:205. doi: 10.1186/1471-2474-12-205537 industrial workers were randomized to examine the effect of strength training at the workplace on non-specific neck and shoulder pain. Participants received 20 weeks of either high-intensity strength training for the neck and shoulders (3 sessions per week) or a control treatment, where patients received advice to stay physically active (1 session per week). The assessment after 20 weeks revealed that high-intensity strength training led to better overall reduction in neck and shoulder pain among industrial workers.
Was the allocation sequence adequately generated?
Was allocation adequately concealed?
Blinding Treatment Providers: Was knowledge of the allocated interventions adequately prevented?
Blinding Outcome Assessors: Was knowledge of the allocated interventions adequately prevented?
Blinding Patients: Was knowledge of the allocated interventions adequately prevented?
Was loss to follow-up (missing outcome data) infrequent?
Are reports of the study free of suggestion of selective outcome reporting?
Were outcomes objective, patient-important and assessed in a manner to limit bias (ie. duplicate assessors, Independent assessors)?
Was the sample size sufficiently large to assure a balance of prognosis and sufficiently large number of outcome events?
Was investigator expertise/experience with both treatment and control techniques likely the same (ie.were criteria for surgeon participation/expertise provided)?

Der Fragilitätsindex ist ein Instrument, das bei der Interpretation signifikanter Ergebnisse hilft und ein Maß für die Stärke eines Ergebnisses liefert. Der Fragilitätsindex gibt die Anzahl der aufeinanderfolgenden Ereignisse an, die zu einem dichotomen Ergebnis hinzugefügt werden müssen, damit das Ergebnis nicht mehr signifikant ist. Eine kleine Zahl steht für ein schwächeres Ergebnis und eine große Zahl für ein stärkeres Ergebnis.
Warum wurde diese Studie jetzt benötigt?
Of the musculoskeletal conditions that are often reported in association with the workplace, neck and shoulder pain represent two of the most commonly reported ailments. The discomfort is thought to be mainly manifested through physical factors, such as repetitive tasks and tiring postures. Strength training has been offered as a efficacious intervention to alleviate neck and shoulder pain, although the evidence in support of strength training has been primarily focused in office workers. Accordingly, the effectiveness of strength training in other job settings, specifically the industrial sector, needed to be determined
Was war die wichtigste Forschungsfrage?
Was participating in high-intensity strength training more effective in improving neck and shoulder pain among industrial workers compared to receiving advice to stay physically active, assessed at 20 weeks?
- Regular adherence to the training program (at least once a week) was 85%.
- Pain intensity in the neck decreased significantly in the training group in comparison to the control group (-0.6, 95% CI: -1.0 to -0.1, P < 0.001).
- Pain intensity in the shoulder tended to decrease in the training group (-0.2, 95% CI: -0.5 to 0.1, P = 0.07).
- In respect to the rehabilitative effect of training, the odds ratio for participants defined as cases at baseline (in the training group compared to the control group) for being non-cases at follow-up was 2.0 (95% CI: 1.0 to 4.2) for the neck and 3.9 (95% CI: 1.7 to 9.4) for the shoulder.
- In terms of preventative effect on training, the odds ratio for participants defined as non-cases at baseline (in the training group compared to the control group) for being cases at follow-up was 0.6 (95% CI: 0.2 to 1.5) for the neck and 0.6 (95% CI: 0.3 to 1.3) for the shoulder.
Was sollte ich mir besonders merken?
This study revealed that the specific strength training program reduced the overall neck and shoulder pain among industrial workers when compared to the control treatment.
Wie wird sich dies auf die Behandlung meiner Patienten auswirken?
This study suggests that the strength training program provides clinically important reductions in neck and shoulder pain in a population of industrial workers over 20 weeks. However, maintenance of improvements in neck and shoulder pain should be determine in studies with follow-up periods. Comparisons to other exercise/training protocols should also be considered.
