Musculoskeletal and Orthopedic Conditions

For osteoporosis/osteopenia, weight-bearing aerobic activity (walking, stair climbing) combined with progressive resistance training stimulates bone formation and is the mainstay of the prescription; balance training is added to reduce fall risk. High-impact activities and movements that combine spinal flexion with loading or rotation are avoided in patients with significant fracture risk or existing vertebral compression fractures, since these movement patterns are specifically associated with vertebral fracture. For osteoarthritis and rheumatoid arthritis, low-impact aerobic modes (aquatic exercise, stationary cycling) reduce joint loading while range-of-motion and strengthening work targets the muscles supporting the affected joint; exercise is held during an acute inflammatory flare and resumed as symptoms allow. Rheumatoid arthritis programming additionally accounts for morning stiffness by scheduling sessions later in the day when feasible, applies joint-protection principles (larger joints and proper body mechanics over repetitive small-joint stress), and monitors for the systemic fatigue that often accompanies disease activity, scaling volume back on higher-symptom days rather than holding to a fixed schedule. Chronic low back pain programs emphasize core/trunk stabilization and are individualized to any known directional preference (e.g., minimizing prolonged flexed postures when extension relieves symptoms).

Neuromuscular and Neurological Conditions

• Stroke: task-specific, functional training (gait, balance, reaching) starting at low intensity (RPE 11–13) and progressing as tolerated; blood pressure is monitored closely because autonomic dysregulation is common, and fall precautions and one-sided (hemiparetic) considerations shape exercise selection.
• Multiple sclerosis (MS): exercise is performed in a cool environment, since heat and humidity can transiently worsen symptoms — a heat-sensitivity response known as Uhthoff's phenomenon. Pre-cooling strategies (cooling vests, cold drinks) and energy-conservation pacing help manage the fatigue that is common in MS.
• Parkinson's disease: sessions are scheduled during medication "on" periods, when dopaminergic medication is at peak effect, because this is when motor control, movement amplitude, and gait are best and rigidity/bradykinesia are least limiting; training emphasizes large-amplitude ("big") movements, balance, and gait.
• Spinal cord injury (SCI): for lesions at or above T6, there is risk of autonomic dysreflexia — a sudden, severe hypertensive episode with pounding headache, sweating above the lesion level, and reflex bradycardia, typically triggered by a noxious stimulus below the injury level such as a distended bladder or bowel. The response is to stop exercise immediately, identify and remove the trigger, and seek emergency care if the episode does not resolve quickly. SCI patients are also prone to exercise-induced hypotension and impaired thermoregulation below the level of injury (loss of sweating), requiring close monitoring of core temperature and hydration.

Neoplastic, Immunologic, and Hematologic Conditions

Cancer patients generally follow standard aerobic (≥150 min/week moderate) and resistance (2 days/week) targets from exercise-oncology guidelines, individualized around treatment-related blood-count precautions:

Lymphedema is not a contraindication to resistance training — current guidance supports gradual, progressive resistance exercise of the affected limb with a well-fitted compression garment, while monitoring limb volume for change, reversing the older practice of restricting all loading of that limb.

Immunologic Conditions

For patients living with HIV/AIDS, exercise (combined aerobic and resistance training) is well supported for improving cardiorespiratory fitness, preserving lean body mass, and mitigating antiretroviral-related metabolic changes such as lipodystrophy and dyslipidemia. Prescription follows standard FITT parameters for the patient's fitness level, with additional attention to CD4 count and current opportunistic-infection status — significant immunosuppression warrants the same infection-exposure precautions (avoiding crowded public exercise settings during active illness) used for neutropenic cancer patients, and any new fever or unexplained symptom should be evaluated before continuing a session.

Renal Disease

For patients on hemodialysis, resistance exercise is performed on the non-fistula arm to protect the vascular access site. Mild-to-moderate intensity aerobic exercise can be performed during the first half of a hemodialysis session for patients who tolerate it, or between sessions on non-dialysis days if intradialytic fatigue is high; fluid and electrolyte status should be considered when timing and dosing exercise around dialysis, since interdialytic fluid overload can raise blood pressure and cardiac workload while post-dialysis hypotension and fatigue can limit same-day tolerance. Renal patients also frequently carry comorbid cardiovascular disease and diabetes, so the CAD and diabetes precautions described earlier in this chapter typically apply in combination, not in isolation.

Across every population in this section, the common thread is that a single diagnosis label is not enough to write a safe prescription — the specific complication (fracture risk, heat sensitivity, medication timing, autonomic level, or lab values) determines the actual FITT-VP modification.
