By using an innovative ground-based analogue model, we are able to simulate a space mission including a trip to (0 g) and a stay on Mars (0.38 g) in rats. This model allows for a longitudinal assessment of the physiological changes occurring during the two hypo-gravitational stages of the mission.

Dual fluoroscopy accurately captures in vivo dynamic motion of human joints, which can be visualized relative to reconstructed anatomy (e.g., arthrokinematics). Herein, a detailed protocol to quantify hip arthrokinematics during weight-bearing activities of daily living is presented, including the integration of dual fluoroscopy with traditional skin marker motion capture.

Lung Capacity

The air in the lungs is measured in volumes and capacities. Lung volume measures reflect the amount of air taken in, released, or left over after a lung function, like a single inhalation. Lung capacity measures are sums of two or more lung volume measures. There are four defined lung volume measures: tidal volume, inspiratory reserve volume, expiratory reserve volume, and residual volume. Tidal volume is the amount of air inhaled and exhaled in a normal breath. Inspiratory...
FAQs
Capacity may decrease when bone strength, joint stability, muscle force, tissue healing, or pain limits loading. These factors can interact: reduced muscle force may impair support, while pain may restrict functional use even when structural healing is progressing. Considering them together helps clinicians avoid judging readiness from a single finding alone.
The same total load may produce different demands depending on how it is distributed and how long it is applied. Clinicians therefore consider both the amount of force and the conditions under which a limb, joint, or implant experiences it. This supports more precise mobility planning and helps limit excessive stress during recovery.
The limiting factor may differ according to the structure being evaluated. Bone strength, joint stability, muscle force, tissue healing, or the integrity of an implanted device can each determine how much loading is appropriate. Identifying the relevant structure allows assessment and activity progression to reflect the patient’s specific musculoskeletal problem rather than applying one standard threshold.
Pain is one of the clinical factors used to judge whether loading is tolerated, alongside examination findings, imaging, and functional performance. Persistent or limiting pain can indicate that progression requires reassessment, even when other measures appear favorable. Including pain in the evaluation helps connect structural information with the patient’s actual ability to move safely.
Assessment can combine physical examination, imaging, and functional evaluation. Physical examination contributes information about stability, muscle force, pain, and healing, while imaging helps evaluate relevant structural conditions. Functional assessment shows how the person manages movement and loading. Together, these sources support a more informed decision than any single assessment method alone.
Clinicians may guide progression from non-weight-bearing to partial and then full weight-bearing activity, using the person’s clinical and functional findings to determine readiness. This staged approach allows loading to increase under controlled conditions rather than changing abruptly. It is used to support recovery while reducing the risk of reinjury or implant failure.
The measure informs mobility plans, assistive-device selection, postoperative recovery, fracture management, and return to daily activities. It is particularly useful when clinicians must match a person’s current loading tolerance with an appropriate level of support or activity. Applying the assessment in these settings helps balance functional progress with protection of healing tissues and implants.
By combining structural, clinical, and functional information, clinicians can determine whether current activities match the person’s loading tolerance. They can then select assistance and advance movement from non-weight-bearing through partial or full loading as appropriate. This individualized planning supports mobility while reducing exposure to loads that could contribute to reinjury or implant failure.
