using DXA for research applications can be limited by the high cost of scanning and lack of machine accessibility. To address these concerns, tissue mass prediction equations using anthropometric measures have been developed and validated against DXA scans for segments of the lower 14 and upper

(particularly those with fewer resources) may prevent many coaches and athletes from using them, making running mechanics evaluation and long-term follow-up impossible. For this reason, many researchers have looked at the validation of more affordable and practical devices to measure running mechanics, mainly

practical estimation methods for the CoM velocity in swimming direction during front crawl swimming with underwater cameras and to validate these methods against the CoM velocity as calculated using the segmental method (ie, the gold standard method). Methods Procedure Ten competitive swimmers participated

intended for performing experimental tests. (B) An artificial arm mechanism installed on the handbike for method validation. The marker positions are displayed. Kinematics of the upper limbs was directly obtained by a 2-camera motion capture system (SMART-DX100), made by BTS Bioengineering (Milan, Italy

. If this change was less than these MCD values, we cannot conclude that athlete’s function has significantly improved after treatment. The FAAM-T MDC values were higher than the values reported for the English version (ADL MDC: 5.7; Sport MDC: 12.3) and other validation studies. 14 , 32 , 34 These

–7 times per week]). A validation study of this instrument found symptoms of sleep apnea loaded on a single factor (MAP Index 1; average frequency of loud snoring, breathing cessation, and snorting/gasping) and had good test–retest reliability ( r  = .92). 15 Predictive ability was assessed using receiver

Clinical Bottom Line There is moderate evidence to support subsymptomatic aerobic exercise as a treatment of PCS; therefore, it should be considered as a clinical option for reducing PCS and prolonged concussion symptoms. Clinicians should use a previously validated protocol to determine subsymptomatic

, tissue mass prediction equations for the upper 12 and lower 14 extremities have been developed from simple surface anthropometric measurements (lengths, circumferences, breadths, skinfolds) and validated against the actual tissue masses provided by DXA. These regression equations allow for the

Cryotherapy decreases the tissue metabolic rate, 14 promotes superficial vasoconstriction, 15 decreases vascular permeability, 16 and leads to

. More recently, authors have considered low-cost instruments like the inclinometer that may be used in field conditions to assess the JPS in a more clinician-friendly way. 7 , 9 , 10 Previous studies have validated this methodology to assess the JPS in shoulder rotations and knee extension and flexion
