I'd ask for specific information about what residents do after residency: Fellowships, private practice, academia? Does the program have a good alumni network to help residents find a job? Some places like RIC, Seattle, and Mayo have strong alumni networks and this makes a difference how easily residents find a job.
Ask about procedural training and EMGs: If a program can't commit to 250 quality EMGs and basic exposure to rudimentary injection techniques (or at least the opportunity to attend workshops and conferences to learn some of these techniques)---then move along...
Ask about didactics: They should be faculty-directed (with the exception of maybe a journal club or board-prep group that should have substantial involvement from upper-level residents).
Ask about board pass rates: Good programs, obviously, have high pass-rates...
Ask about electives: Rehab is the most interdisciplinary field in medicine. Therefore, good programs have excellent departmental relationships and residents have no problems doing electives in rehab-related specialties: Trauma, neurosurgery, rheumatology, sports medicine, orthopedic spine, anesthesia/pain management, occupational medicine, urology, neurology, etc.
Working environment/conditions: Are the residents over-worked? Are residents well-supervised or hung out to dry? Do residents have time to read, study, do small scale research projects?
Research infrastructure: Programs with good infrastructure attract intellectually curious individuals and top faculty.
Things to watch out for...
---residents having to scramble for EMGs and procedures. EMG trainig should include work with both neurologists and physiatrists.
---lack of structure or "cohesiveness" in a program. You should feel like you're interviewing at a program with a solid identity about what it is and where it is going...
---selective meetings with residents. The residents you will meet at specific programs are usually the politically-connected ones. If a program doesn't offer some sort of open catered "mixer" where any old resident can stop in and say "hi" they may be trying to hide something from you.
---malignant faculty. You'll know. It's a gut instinct.
---lack of pride. If residents seem like they're just going through the motions, this is a bad sign.
---lack of balance. Good programs basically have a training gradient from inpatient to outpatient as one progresses through PGY2-PGY4. Some programs have an inpatient senior rotation in PGY4 which is fine. At almost all programs, your PGY2 is inpatient oriented, but by PGY3 you should be getting into rehab specialty clinics (sports, spine, arthritis, pediatric, etc).
Good things to notice and appreciate:
---model systems for brain and spinal cord injury
---multidisciplinary specialty clinics in spine, sports, occ med, etc.
---diverse faculty. Good programs have at least one faculty in each "core area" of rehab: TBI, SCI, MSK/spine, sports, general/geriatric, occ med.
---moonlighting opportunities in rehab related areas in PGY3 and PGY4 years
---programs with leaders or who have trained leaders in the field: Do names like DeLisa, Frontera, Zafonte, Kraft, Herring, Stolov, etc ring any bells?
---Gait labs, flouroscopy suites, dedicated EMG facilities, etc.
