Objective:
To evaluate the effect of a physical training program in combination with ergonomic changes in a group of keyboard operators with nonspecific/type II work-related upper limb disorder (WRULD).
Design:
Prospective study.
Setting:
Hospital department.
Participants:
Pain-free controls (n=6) and currently working patients with WRULD (n=17) were included.
Interventions:
Participants were taught how to self-rehabilitate according to a previously published physical exercise program, in addition the patients requested maximal ergonomic assistance from their employer according to British law.
Main Outcomes Measures:
Pain at rest and after a standardized functional typing test, before and after rehabilitation, with recording of endurance and calculation of typing speed during the tests. Statistical evaluation: Student t test, paired, and 2-tailed.
Results:
After the rehabilitation program, the patients as a group had significantly less pain both at rest (P=.009) and after the typing test (P<.001). The typing endurance improved significantly (P=.027) and became similar to the healthy control group (P =.09). The typing speed improved significantly in the patient group after rehabilitation (P=.032) and became similar to the normal control group (P=.058).
Conclusions:
Currently working keyboard operators with nonspecific/type II WRULD can benefit significantly from a combination of an individualized self-administered physical rehabilitation program and ergonomic work place improvements. Randomized control studies are needed to further investigate the long-term effect of this encouraging finding.
