Effect of Neuromuscular Electrostimulation With Blood Flow Restriction on Acute Muscle Swelling of the Abductor Hallucis
Kazunori Okamura et al
J Sport Rehabil. 2023 Dec 28;33(2):121-127.

Context: Plantar intrinsic foot muscle strength training is difficult to master to a degree sufficient to elicit muscle hypertrophy in most individuals. It is possible that combining neuromuscular electrostimulation (NMES) and blood flow restriction (BFR) can elicit plantar intrinsic foot muscle hypertrophy regardless of the individual's technique. This study aimed to determine the effects of NMES training with BFR on acute muscle swelling in the abductor hallucis.

Design: Randomized, controlled, single-blind trial design.

Methods: Forty-eight participants were randomly allocated to the NMES + BFR, NMES, or Sham NMES + BFR groups. All participants received abductor hallucis NMES for 15 minutes. Participants in the NMES + BFR and Sham NMES + BFR groups received NMES with BFR. The intensity of NMES was the sensory threshold in the Sham NMES + BFR group. The cross-sectional area of the abductor hallucis was measured pretraining and posttraining using ultrasonography by a single investigator blinded to the participants' allocations.

Results: After 15 minutes of training, the cross-sectional area of the abductor hallucis was significantly increased in the NMES + BFR (P < .001) and the Sham NMES + BFR (P = .004) groups. Moreover, the rate of increase was significantly higher in the NMES + BFR group than in the NMES or the Sham NMES + BFR groups (P < .001 and P = .001, respectively).

Conclusions: Since it is possible that the amount of muscle swelling immediately after training correlates with muscle hypertrophy when training is continued, the results of this study suggest that NMES training with BFR is a training method that can be expected to produce plantar intrinsic foot muscle hypertrophy. Further studies are needed to confirm the long-term effects of NMES training with BFR.

Feasibility of Blood Flow Restriction Exercise in Adults with a Non-surgically Treated Achilles Tendon Rupture; a Case Series
ANDREAS BENTZEN et al
International Journal of Exercise Science 17(3): 140-153, 2024.

Blood flow restriction exercise (BFRE) appears to provide a unique opportunity to preserve lower limb muscle and function in patients with an Achilles tendon rupture. The purpose of this study was to investigate the feasibility of BFRE in patients with an Achilles tendon rupture. Additionally, to evaluate muscle volume and patient-reported ankle function, symptoms, complications, and physical activity following 12 weeks of BFRE. Feasibility was measured by adherence to training sessions, drop-out rate, intervention acceptability, ankle pain exacerbation (NRS), and adverse events. At baseline and 12-weeks follow-up, patients completed the Achilles Tendon Total Rupture Score questionnaire and had their thigh and calf circumference measured. At follow-up, patients’ ability to perform a single-leg heel rise was tested. Sixteen of 18 patients completed the intervention and for those, adherence to training sessions was 88% ±16%. The mean NRS following BFRE sessions was 1.1 (95%CI: 1; 1.2). Three adverse events occurred during the 12 weeks. Two re-ruptures after completion of the BFRE program and one deep venous thrombosis following cast removal. BFRE was found to be feasible in a subset of patients with an Achilles tendon rupture. However, with three adverse events in a population of 18 patients, the effectiveness and safety of BFRE warrants further investigation.
