Article Synopsis
- * A study using a population-based survey found that higher tinnitus severity scores are associated with a greater impact on work functioning among Veterans.
- * Veterans with a traumatic brain injury (TBI) are more likely to experience a high impact from tinnitus on their work, although the severity of tinnitus affects work functioning similarly for both those with and without TBI.
Background: Gait and balance impairments are among the main causes of falls in older adults. The feasibility and effectiveness of adding sensor-based feedback to physical therapy (PT) in an outpatient PT setting is unknown. We evaluated the feasibility and effectiveness of PT intervention combined with a therapist-assisted visual feedback system, called Mobility Rehab, (PT + MR) in older adults.

- The study examines how freezing of gait (FOG) in people with Parkinson's disease (PwPD) affects their ability to complete tasks while walking.
- It found that those with definite-freezing (dFOG) have worse dual-task costs (DTC) in various gait parameters compared to non-freezers (nFOG).
- Additionally, cognitive function and gender differences play significant roles in DTC, highlighting the need for considering these factors in assessments of walking performance in PwPD.
Background: Methods for modulating the cerebellum with transcranial magnetic stimulation (TMS) are well established, and preliminary data from our group and others has shown evidence of transient improvements in balance after cerebellar repetitive transcranial magnetic stimulation (rTMS) in progressive suprancuclear palsy (PSP). This study examines extensive posturography measures before and after 10 sessions of cerebellar rTMS and sham TMS in PSP.
Methods: Thirty subjects with PSP and postural instability will undergo cerebellar active and sham rTMS in a single-blind, crossover design with a randomized order of a 10-day intervention.
Introduction: Research in court sports shows that factors which aid in extrinsic shock absorption, that is, flooring and footwear, can help reduce lower extremity injuries. However, since students and performers of ballet or most styles of contemporary dance cannot depend upon footwear, the only extrinsic factor to help them with shock absorption is flooring.
Methods: We investigated whether doing sauté on a low stiffness dance floor produced a difference in EMG output of the vastus lateralis, gastrocnemius, of soleus compared to a high stiffness floor.
