Roni Caryn Rabin, "No Easy Choices on Breast Reconstruction", NYT Blogs 5/20/2013:
A syndrome called upper quarter dysfunction — its symptoms include pain, restricted immobility and impaired sensation and strength — has been reported in over half of breast cancer survivors and may be more frequent in those who undergo breast reconstruction, according to a 2012 study in the journal Cancer. [emphasis added]
Reader E.S.M. wondered whether "restricted immobility" should have been "restricted mobility" or "partial immobility" or something else.
Some evidence for this view comes from Margaret L. McNeely, et al., , "A prospective model of care for breast cancer rehabilitation: postoperative and postreconstructive issues", Cancer 2012 (which appears to have been one of Ms. Rabin's sources):
The presence of upper quarter dysfunction (UQD), defined as restricted upper quarter mobility, pain, lymphedema, and impaired sensation and strength, has been reported in over half of survivors after treatment for breast cancer.
And in general, "restricted mobility" seems to be quite common in scientific and technical writing, whereas "restricted immobility" is rare.
Logically, "restricted mobility" is also "restricted immobility". "Restricted X" obviously has less of the natural properties of X than unrestricted X does, while still having some of them, and "restricted lack of X" also places us somewhere in the middle of the X scale. So perhaps this should be a free choice.
But in phrases of the form "restricted X", we generally think of X as unrestricted in the normal state, with the restrictions as something added on in certain cases. The commonest nouns following restricted in the COCA corpus are
stock, access, area, range, areas, airspace, use, zone, diet, model, shares, mobility, space, air, immigration, movement, sense, opportunities, set, data, ranges, …
With the partial exception of "immigration", these collocates seem to confirm the notion that the unrestricted case is the normal one, with the restricted case being special. Combining this observation with the usage patterns in the technical literature, I'll tentatively conclude that E.S.M. is right.
