[Purpose] This study aimed to investigate the reliability and validity of measuring isometric ankle plantar flexion strength using a handheld dynamometer (HHD) with a belt and metal plate. [Participants and Methods] This study enrolled 35 young healthy participants (22 men and 13 women, mean age; 21.2 years). To evaluate reliability, two examiners measured ankle plantar flexor strength twice for all participants using an HHD. To evaluate validity, an examiner measured ankle plantar flexor strength twice in men using an isokinetic dynamometer (IKD). [Results] Intra-rater reliability was almost perfect for examiners A and B, whereas their interrater reliability was substantial. Pearson's correlation coefficients for the HHD and IKD in men were not significantly correlated. [Conclusion] The intra- and interrater reliabilities of HHD measurements, as evaluated by the data for all participants, were high. However, the validity of HHD measurements evaluated by men was low if IKD-measured values were used as a reference.

This study examined the acute effects of dynamic stretching at different velocities on the neuromuscular system. Fourteen participants underwent four experimental sessions in random order: (1) control (lying at rest with the ankle in a neutral position); (2) slow velocity dynamic stretching (50 beats/min; SLOW); (3) moderate velocity dynamic stretching (70 beats/min; MOD); and (4) fast velocity dynamic stretching (90 beats/min; FAST). The stretching protocols consisted of four sets of 10 repetitions and targeted the plantar flexor muscles of the right ankle.

Achilles tendon ruptures significantly impair long-term patient function, with two-thirds of patients experiencing persistent functional deficits. Although nonsurgical treatment has gained popularity due to its perceived lower risk of complications, the specific effects of this approach on tendon healing, muscle function, and overall performance remain poorly understood. Directly comparing surgical and nonsurgical treatment options in a clinical population is challenging given the diverse nature of the patient population.

Article Synopsis
- The study aimed to assess the sensorimotor function in patients with unilateral chronic ankle instability (CAI) and compare their abilities to healthy controls, focusing on sensory reweighting and vestibular modulation.
- Twenty individuals with unilateral CAI and twenty healthy participants underwent various tests to evaluate ankle proprioception, plantar sensation, balance, and motor control, using a mix of analyses to compare the groups.
- Results indicated that those with CAI had increased sensory thresholds for light touch and two-point discrimination bilaterally, moderate deficits in certain motor control measures, and showed postural instability in balance tests when compared to healthy controls.

Introduction: Schwannoma is a type of slow growing benign nerve sheath tumor arising from Schwann cells. Peripherally, they are found in association with the ulnar, sciatic and posterior tibial nerves. Peripheral schwannomas, neurofibromas and malignant PNSTs are collectively grouped as peripheral nerve sheath tumors.
