The evolutions of these methods aim to standardize measurements and provide manageable tools in clinical practice for the early diagnosis of musculoskeletal pathologies and to monitor daily improvements of each patient. These new technologies have also become effective for children or adolescents with non-specific back pain and postural insufficiencies. Similarly, new posture analysis techniques are emerging, often driven by the need for fast and non-invasive methods to obtain high-precision results. Fully automated and markerless systems are overcoming these drawbacks for conducting biomechanical studies, especially outside laboratories. The currently gold standard systems of motion analysis, widely used in clinical settings, present several limitations related to marker placement or long procedure time. This review aims to resume the currently used motion and posture analysis systems, clarify and suggest the appropriate approaches suitable for specific cases or contexts.

Consequently, clear discrimination among different measurement systems is required to diversify their use as needed. Technological development of motion and posture analyses is rapidly pro gressing, especially in rehabilitation settings and sport biomechanics.
