This study investigated the pressures occurring within the arm human-machine-interfaces (HMI) of four different exoskeletons that support static and dynamic work at or above head level, and the effects of the HMI on neurovascular supply of the upper extremity using an orthopedic provocation maneuver with raised arms with and without the exoskeletons. Decreased time in the provocation maneuver with exoskeletons indicated a negative effect of the HMIs on the vascular and neural supply of the arm. Average pressure in the static situation was 3.2 ± 0.7 kPa and 4.4 ± 0.4 kPa with regular peak values of 6.5 ± 0.5 kPa in the dynamic task. These pressures were significantly higher than the pressure values that guarantee adequate tissue oxygenation. It remains unknown whether the way exoskeletons apply pressure affects vascular and neural supply to the arms, or whether the regular unloading during dynamic activity has a neutralizing effect.

Background: We have noted that some adolescents and young adults with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) report difficulty with arms-overhead activities, suggestive of brachial plexus dysfunction or thoracic outlet syndrome (TOS). In the TOS literature, diagnostic maneuvers focus on the provocation of upper limb symptoms (arm fatigue and heaviness, paresthesias, neck and upper back pain), but not on elicitation of systemic symptoms.
Objectives: To estimate the proportion of patients with fatiguing illness who experience local and systemic symptoms during a common maneuver used in evaluating TOS-the elevated arm stress test (EAST).

The latest Chicago Classification of esophageal motility disorders categorizes esophageal hypomotility disorders (EHD) into absent contractility (AC) and ineffective esophageal motility (IEM). While these disorders are commonly associated with gastroesophageal reflux disease (GERD), they are not pathognomonic. To improve diagnostic accuracy, provocative maneuvers during high-resolution esophageal manometry (HRM) -such as multiple rapid swallows (MRS) and single solid swallows (SSS) -have been introduced.

Article Synopsis
- Benign paroxysmal positional vertigo (BPPV) causes recurring episodes of vertigo, and despite initial symptom resolution, many patients experience relapses and other complications such as migraines, neck pain, and falls after discharge.
- This study observed 124 patients with BPPV and found that 70.97% of them reported new symptoms post-treatment, with prior neck pain, headaches, and migraines being significant predictors for future issues.
- Key findings highlight that low vitamin D levels may increase recurrence risk, and the relationship between anxiety and persistent postural-perceptual dizziness (PPPD) suggests that BPPV is often accompanied by lingering symptoms despite the absence of nystagmus.
