Passive Hallux Adduction Decreases Posterior Tibial Artery Blood Flow Less than in the Lateral Plantar Artery. Southwest American College of Sports Medicine Annual Meeting. Due to the vital role that blood flow (BF) plays in maintaining tissue health, a compromise to BF can affect tissue healing A passively adducted hallux (PHA), as often seen inside a narrow shoe, was found to decrease BF in the lateral plantar artery (LPA) This was thought to be due to compression of the LPA between the calcaneus and the abductor hallicus (AH) muscle as it tenses with PHA The posterior tibial artery (PTA) is proximal to and supplies the LPA and should allow for a detection site to measure a similar decrease in BF
    PURPOSE: The purpose of this study was to compare the decrease in blood flow within the PTA produced by PHA to that previously measured in the LPA
    METHODS: Twenty-four healthy volunteers (Female n=11, age = 248 ± 68 yr; height = 17 ± 01 m; body mass = 734 ± 135 kg) participated in this study Blood velocity and vessel diameter measurements were obtained using ultrasound imaging (L8-18i transducer, GE Logiq S8) and used to calculate volume of BF The PTA was imaged at medial malleolus for 120 seconds: 60 seconds at rest followed by 60 seconds of PHA, while the LPA was imaged at the location of the AH Maximal PHA was performed by applying pressure to the medial side of the proximal phalanx of the hallux The change in BF at PTA was then compared to the LPA data A repeated measures ANOVA was run to determine the change in BF within the arteries
    RESULTS: A BF decrease of 30% was seen within the PTA with a recovery of 16% over the course of a minute, while the BF decreased 60% in the LPA with a recovery of 30%
    CONCLUSION: There appears to be a compensatory collateral BF at the PTA, likely via the medial malleolar complex allowing BF to continue between the anterior tibial and posterior tibial arteries This anastomosis is not available at the more distally located LPA The PHA decreases BF to the foot, but collateral BF should be considered when assessing this change in BF and its effects on injury and healing.

Annual Meeting of the American College of Sports Medicine. Purpose: The tibialis posterior (TP) is a key muscle in controlling foot function and is associated with several lower extremity pathologies Being able to assess the strength, activity and size of the TP across ages plays an important role in treating and understanding pathologies associated with the TP It may be more difficult to image the TP of older individuals due to fatty infiltration and fibrosis The purpose of this study evaluated the reliability of ultrasonic measurements of the TP in young and older adults
    Methods: Legs of 23 individuals (older (O) n=7; younger (Y) n=16) were imaged via ultrasound (6-15ML probe, GE Logiq S8) and the cross-sectional area (CSA) and thickness of the TP was recorded To measure the TP, the probe was held at a point 30% and 50% between the knee joint line and the inferior tip of the lateral malleolus Subjects inverted their foot and videos of the contraction cycle were recorded Two separate still-shots of the muscle at rest were saved from the recorded videos at each location to make size measurements This process was performed on both anterior and posterior sides of the leg To assess reliability, intraclass correlation coefficients (ICC) and the standard error of the measurement (SEM) were calculated An independent t-test was used to determine differences in the measurement error between age groups
    Results: The average TP CSA at the 30% point for the anterior view was 396 ± 105 cm2, and the posterior was 400 ± 106; at the 50%, the anterior was 343 ± 109 cm2, and the posterior was 355 ± 109 Excellent reliability was seen when comparing repeated measurements for anterior and posterior area and thickness measurements for both younger and older individuals (ICC=937-999), however, there was a significant difference in the SEM for TP thickness (O = 006 ± 002cm; Y = 0035 ± 001cm, p=008) and CSA (O = 011± 007cm; Y = 0046 ± 001cm, p=02)
    Conclusion: Repeated measurements showed excellent reliability in both groups There was a greater error in the measurement in the older adults Despite showing excellent reliability, these results show that age does affect the accuracy of the measurement of the TP muscle size assessed by ultrasound imaging; however, it would also be beneficial to be able to assess quality of muscle tissue.

  • Johnson AWW, Jacobs JL, Ridge SET, Bruening DA, Brewerton KA, Gifford JR, Hoopes D. Passive Hallux Adduction Decreases Lateral Plantar Artery Blood Flow in Low Arch Feet. Annual Meeting of the American College of Sports Medicine. Due to the vital role that blood flow (BF) plays in maintaining tissue health, compromised BF can affect tissue healing An adducted hallux, as often seen inside a narrow shoe, may put passive tension on the abductor hallucis, consequently compressing the lateral plantar artery (LPA) into the calcaneus and restrict BF This may negatively affect the health of tissues within the foot such as the plantar fascia and may contribute to plantar fasciopathy
    PURPOSE: The purpose of this study was to compare BF within the LPA before and after passive hallux adduction (PHA)
    METHODS: Forty-five healthy volunteers (20 female, 25 male; age = 248 ± 68 yr; height = 17 ± 01 m; body mass = 734 ± 135 kg) participated in this study Blood velocity and vessel diameter measurements were obtained using ultrasound imaging (L8-18i transducer, GE Logiq S8) The LPA was imaged deep to abductor hallucis for 120 seconds: 60 seconds at rest followed by 60 seconds of PHA Maximal PHA was performed by applying pressure to the medial side of the proximal phalanx of the hallux BF was then calculated in mL/min, and measurements before and during PHA were compared Arch height index (AHI) was assessed for all volunteers
    RESULTS: Log transformed data was used to run a paired t-test between BF measured before and during PHA The overall volume of BF over the 60 seconds during PHA was 22% lower compared to before (−0250 ± 0063 ml/min, p < 0001), with an initial decrease of 60% As AHI decreased, there was a greater negative DBF As baseline BF increased, there was also a greater negative DBF
    CONCLUSION: Our preliminary findings of decreased BF through PHA indicate conditions that elicit PHA (eg wearing narrow-toed shoes) may affect BF and tissue health. May, 2019.

World Confederation for Physical Therapy 2011. Purpose: The purpose of this study was to determine if repeated bouts of whole body vibration training increase intramuscular temperature in two different lower extremity muscles Relevance: Whole body vibration is becoming a commonly used adjunctive training modality in rehabilitation and among sports teams due it´s myriad of reported benefits from current research It is also touted as a good warm-up modality although very little research exists to support this claim Participants: 10 recreationally active college-aged males participated in this study (average age 23 ± 43 yrs, body mass 764 ± 90 kg, height 176 ± 01m) Methods: All 10 qualified subjects underwent two separate conditions (static semisquat with repeated bouts of whole body vibration (WBV), and static semisquat without vibration(SS)) on two separate days (5-7 days apart) Distribution of testing was blocked to minimize a possible order effect For the WBV intervention subjects underwent the following protocol: Subjects first had their baseline intramuscular temperature measured for 20 minutes via insertion of a 26-gauge thermistor 1cm deep into the vastus lateralis and a 29-gauge ½ cm deep into the muscle of the medial head of the gastrocnemius of the right leg The thermistors were then removed and subjects underwent 5x60-second repetitions on Galileo 2000 vibration platform in a 40 degree knee flexed semi-squat position with 30-second rest periods between sets (26Hz at 42 mm amplitude) Immediately following, thermistors were reinserted into the same spot and intramuscular temperature was assessed for 1 minute The thermistors were then removed again and the subjects repeated the same 5x60 second protocol Intramuscular temperature was then assessed again with thermistors left in until the temperature returned to baseline This same protocol was used for the SS intervention, except the vibration platform was never turned on Analysis: Data were analyzed using a repeated measures ANOVA with post hoc analysis as indicated Results: Group x time differences were detected for the gastrocnemius (F(2,18) = 3417, p= 014) and the vastus lateralis (F(2,18) = 542, p=0001) Post hoc testing revealed increases in gastrocnemius temperature following WBV, while the SS condition elicited decreases in gastrocnemius temperature (p<05) The vastus lateralis temperature increased more in the WBV group than the SS after each intervention (<05) Conclusions: Surprisingly only 1 other study has reported on intramuscular temperature of the vastus lateralis, but a continuous static squat for 10-minutes was used Our study shows that WBV does elicit greater vastus lateralis intramuscular temperature following similar vibration training sets mentioned in other studies Surprisingly the gastrocnemius intramuscular temperature decreased by more than 1 degree Celsius without vibration and increased 108C with vibration Vastus lateralis temperature increased an average of 146C in the SS and 198C in the WBV interventions Implications: Whether or not this decline in gastrocnemius temperature exists with dynamic squatting requires further investigation Static standing/squatting exercise alone may not induce a below the knee intramuscular warming effect, however, it appears that whole body vibration training produces significant warming effect as measured by intramuscular temperature Key-words: 1 vibration 2 temperature 3 intramuscular Funding acknowledgements: None Ethics approval: This study was approved by the University Institutional Review Board for ethical research.
