The question presented is whether, consistent with our recent decision in
Grant v. Schweiker,
I
Smith’s claim for disability benefits was heard by an administration law judge (ALJ) in May 1980, after the Social Security Administration (SSA) had denied his claim. The uncontroverted evidence introduced at the hearing indicated that Smith suffers from numerous physical infirmities, the primary one being progressive deterioration of his left hip joint which causes him pain in walking for any distance and prevents his stooping or lifting heavy objects. Smith also testified he was in constant and severe pain due to his hip condition, though the ALJ found this lacking in credibility because not substantiated by the medical evidence.
The other prong of evidence, more critically at issue on this appeal, was a psychiatric examination of Smith performed for the SSA by a Dr. Niklewski. As summarized by the ALJ, Dr. Niklewski’s report was that
[Smith’s] conversation was coherent and relevant and his mental activity was alert and his orientation was good. His intellectual function showed no deficits in memory or other aspects of performance. His mood appeared to be mildly depressed and his affect was anxious, as reflected in his tense manner of speech, voluble recitation of physical symptoms and a slight tremor. He displayed no evidence of psychosis such as delusions, ideas of reference, or paranoid ideation. The diagnosis was anxiety neurosis.... From an emotional standpoint, he suffers from a good deal of tension and anxiety as well as depression. He has not received specific treatment for his emotional state which does not appear to produce significant social, personal, or occupational regression in itself. However, combined with the physical symptoms, it would appear that his anxiety has an additive effect. It was the [doctor’s] opinion that from a strictly emotional viewpoint, [Smith] does not have a mental impairment so severe that he is unable to engage in substantial gainful activity but “that his disability should be determined strongly on a physical basis in combination with the added stress of his anxiety.”
The ALJ’s determination, later adopted by the Secretary, that Smith was not “disabled” within the meaning of the Act,
see
42 U.S.C. § 423(d)(1)(A), flowed from a straightforward application of the “grid regulations,”
see generally Heckler v.
Campbell, - U.S. -,
After the district court found the Secretary’s denial of benefits to be supported by substantial evidence, Smith noticed the instant appeal.
II
If Smith’s ailing hip, associated physical ailments, and related pain were the only evidence of disability presented to the Secretary, we think it plain that the denial of benefits based upon a straightforward application of the grid regulations would be supported by substantial evidence. The record reflects that Smith is ambulatory without cane or crutches, that he can stand for brief intervals and can sit for longer periods, and that he retains full strength and maneuverability in his upper body. This clearly suffices as support for the Secretary’s determination that Smith has the residual capacity to engage in sedentary *725 work, and for the ultimate finding of “not disabled” based upon application of the grids. 2
The potential wrinkle in this case arises because Smith introduced evidence of anxiety neurosis and depression additional to his physical maladies. The crux of Smith’s argument on appeal is that, because he suffers from “nonexertional impairments” in combination with his exertional impairments, the grid regulations cannot be controlling, but instead the Secretary must prove by specific vocational evidence that Smith can perform jobs in the national economy. This presents for decision the very narrow issue of whether, once Smith made out a prima facie case of disability,
see Hall v. Harris,
In
Grant v. Schweiker,
demonstrates the presence of nonexertional impairments, the Secretary, in order to prevail, must be required to prove by expert vocational testimony that, despite [the claimant’s] combination of nonexertional and exertional impairments, specific jobs exist in the national economy which he can perform. The grids may satisfy the Secretary’s burden of coming forward with evidence as to the availability of jobs the claimant can perform only where the claimant suffers solely from exertional impairments.
Id. at 192. We cannot agree with Smith that Grant controls here. Although Grant makes clear that reliance on the grids is precluded where the claimant suffers from a “nonexertional impairment,” not every malady of a “nonexertional” nature rises to the level of a “nonexertional impairment.” The proper inquiry, under Grant, is whether a given nonexertional condition affects an individual’s residual functional capacity to perform work of which he is exertionally capable. If the condition has that effect, it is properly viewed as a “nonexertional impairment,” thereby precluding reliance on the grids to determine a claimant’s disability.
If a nonexertional condition reduces an individual’s residual functional capacity to perform sedentary work, it is inappropriate to apply the grids because the range of jobs available to the impaired claimant is narrower than the grids would indicate. It is amply clear, however, that not all nonexertional conditions or limitations affect an individual’s capacity to perform such work. Whether a given nonexertional condition affects a particular claimant’s residual capacity to engage in certain job activities is a question of fact.
See Cummins
v.
Schweiker,
This treatment of nonexertioanl conditions surely comports with the legislative intent underlying the enactment of the grid regulations.
See generally Heckler v.
Campbell, - U.S. -,
With this understanding, we hold that it was entirely proper for the Secretary to deny benefits to Smith based upon a routine application of the grid regulations.
AFFIRMED.
Notes
. Specifically, the ALJ held: “claimant’s intellectual functions [are] not impaired and ... he [is] not suffering from emotional symptoms that would result in significant social, personal or occupational regression ... [and this] clearly rule[s] out the possibility that the claimant suffers from a psychiatric problem which would prevent him from engaging in sedentary types of employment.”
. On appeal, Smith contends that the ALJ improperly discounted the evidence of Smith’s pain in determining his capacity to engage in sedentary work. But we find substantial evidence in the record to support the ALJ’s conclusion that Smith’s pain — though severe when he engages in weight-bearing activities — would not preclude sedentary work.
. A claimant’s disability is of course established if his nonexertional condition is a “listed impairment” in the Regulations. See generally 20 C.F.R. Part 404, Subpart P, Appendix 1. In such a case it is unnecessary to resort to the grids. Smith rightly concedes that his anxiety and depression, even if proven, do not rise to the level of an “impairment” listed in the Regulations.
