Connie Gretillat alleged that her employer, Care Initiatives, forced her to retire or be terminated in violation of the Americans with Disabilities Act (ADA), 42 U.S.C. § 12101 et seq., and the Iowa Civil Rights Act (ICRA), Iowa Code § 216.6(l)(a). The district court 1 granted summary judgment to Care Initiatives, holding that Gretillat was not disаbled under the ADA and therefore not entitled to its statutory protection. Gretillat appeals, arguing that not only was she disabled, but that she was otherwise qualified for the job as long as she was provided reasonable accommodations for her disability and that Care Initiatives knew of her disability and forced her to depart because of it. We affirm.
I.
Gretillat started working as a Dietary Services Manager for the Valley View nursing home in 1990. Care Initiatives operated the nursing home. In 1993, Care Initiatives issued a job description for her position, which Gretillat signed. Essential functions of the Dietary Service Manager, as enumerated in the job description, included performing “any food service task necessary [for the] provision of meals according to schedule and standards of practice” and “[covering] for absent staff if unable to find a replacement.” The document also specified stooping, kneeling, *651 crouching, and crawling as physical activities associated with the job. 2
Gretillat covered full shifts as a сook through the mid-1990s because the leanly staffed kitchen could not otherwise prepare necessary meals. When Valley View’s resident population increased, more cooks were hired. From that point on, Gretillat covered two- to three-hour kitchen shifts only on occasion. Sometime in 1999, Gretillat began experiencing severe pain in her right knee which was later diagnosed as osteoarthritis. At that time, her supervisor, Monte Priske, observed Gretillat having trouble walking long distances. He thereafter excused her from making rounds of the facility — a task not considered an “essential function.”
Gretillat underwent knee-replacement surgery in September 2003. In November 2003, Gretillat’s physician, Dr. Margaret Fehrle, released Gretillat to return to work. The restrictions form completed by Dr. Fehrle and given to Care Initiatives indicated that Gretillat was released without restriction. 3
As the nursing home population decreased, Care Initiatives likewise had a reduced need for dietary care planning services. Instead of cutting her staffs hours, Gretillat reduced her own hours. At some point after her surgery, Gretillat asked Priske for additional dietary care planning hours. Priske indicated that because of the declining resident population no additional dietary care planning work was required, and that if Gretillat intended to return to full-time hours, she would have to work in the kitchen. In December 2003, after receiving a request for a restriction from Gretillat, Dr. Fehrle faxed to Care Initiatives a new form restricting Gretillat from standing on her right knee for more than an hour without rest. All other restrictions on this updated form remained unchecked.
Gretillat was seen by Dr. Fehrle on February 17, 2004. After examining Gre-tillat’s right knee, Dr. Fehrle concluded that she was doing well and could return to work and “do whatever she wishes.” That same day, Gretillаt covered for absent staff in the kitchen. After working for three-and-a-half hours of a four-hour shift, Gretillat was unable to walk, was limping, and was experiencing a good deal of pain. She declared that she “[couldn’t] take it anymore” and that she was unable tо work the full kitchen shift. Priske then asked Gretillat to participate in a fitness-for-duty examination (FFD).
Wendy Paca, a nurse practitioner, conducted the FFD examination. Paca asked Gretillat to squat, kneel, crouch, and crawl, but Gretillat refused to coоperate. Paca’s FFD report stated that Gretillat would not attempt the requested tasks, cited Gretillat as having said that attempting the tasks would be contraindicated given the recency of her knee surgery, and conveyed Gretil-lat’s contention thаt she could not complete the tasks on that day even were she to try.
After having had an opportunity to review Paca’s report, Priske told Gretillat that she would be expected to work in the kitchen two to three days a week. Since Gretillat could not do this, Priske allowed her to choose between termination and *652 resignation. Gretillat resigned effective March 26, 2004.
Thereafter, Gretillat brought this action, alleging that by requiring her to perform full kitchen shifts, Care Initiatives removed a reasonable accommodation previously provided to her аnd thereby discriminated against her because of her disability. In granting Care Initiatives’ motion for summary judgment, the district court held that there were no genuine issues of material fact and that as a matter of law Gretillat could not succeed in her claims becausе she was not disabled within the meaning of the ADA.
II.
We review the district court’s grant of summary judgment
de novo. See Wood v. Crown Redi-Mix, Inc.,
Gretillat’s claim alleges disability discrimination under the ADA and ICRA. Where, as here, the parties do not dispute the application of federal analysis, disability claims under the ICRA are generally analyzed in accord with the ADA.
See McElroy v. State,
The ADA prohibits employer “discrimi-nat[ion] against a qualified individual with a disability because of the disability of such individual in regard to ... the hiring, advancement, or discharge of employees....” 42 U.S.C. § 12112(a) (2006). The core of every ADA disability definition involves a physical or mental impairment that substantially limits one or more major life activity. 42 U.S.C. § 12102(2) (2006);
see also Nuzum,
The terms “major life activities” and “substantiаl limitation” must be “interpreted strictly to create a demanding standard for qualifying as disabled_”
Toyota Motor Mfg., Kentucky, Inc. v. Williams,
A. Limitations Known to Care Initiatives
The district court considered only the walking and standing limitations of which Care Initiatives had knowledge. Walking and standing are major life activities.
Fjellestad v. Pizza Hut of Am., Inc.,
B. Limitations Not Known to Care Initiatives
After Gretillat’s "departure from Care Initiatives, Dr. Fehrle submitted a conclusory affidavit stating, inter alia, that (1) she considers Gretillat disabled both before and after the knee surgery; 4 (2) Gretillat’s ability to kneel, сrouch, squat and crawl is significantly worse than that of average individuals of her age and sex; (3) Gretillat is permanently restricted in kneeling, crouching, squatting and crawling; and (4) she had not previously indicated these restrictions on forms provided to Care Initiatives beсause she had misunder *654 stood the physical requirements of Gretil-lat’s job.
Even accepting,
arguendo,
that Gretil-lat’s impaired knee substantially and permanently restricts her ability to crawl, kneel, crouch, and squat, these functions cannot meet the demanding standard required by
Williams
for us to consider them major life activities.
Williams,
Nor is there any indication that Gretillat’s limitations, taken together, severely limit any major life activity.
See Nuzum,
The judgment is affirmed.
Notes
. The Honorable Linda R. Reade, now Chief Judge, United States District Court for the Northern District of Iowa.
. In 2003, Care Initiatives issued a revised version of this document detailing the prоportion of time a Dietary Services Manager would be engaged in each physical activity. Gretillat did not sign the revision.
. The form had unmarked check-boxes next to potential restrictions. The unchecked restrictions included those of bending, crawling, reaching, squatting, stooping, finger movement, climbing, kneeling, sitting, standing, walking, and wrist and hand movement.
. A medical diagnosis of an impairment cannot qualify as a disability
per se;
instead, a plaintiff "must satisfy the ADA's demanding standard in each individual case in the context of the major life activity assеrted.”
Ristrom,
. Gretillat also contends that she is substantially limited in the activity of working. Even were we to treat working as a major life activity,
