Comparative StudyCombined thumb abduction and index finger extension strength: a comparison of older adults with and without thumb carpometacarpal osteoarthritis.
The objectives of this study were to compare thumb combined abduction/index finger extension (hand opening) strength between subjects with carpometacarpal (CMC) osteoarthritis (OA) and normal controls and to assess the reproducibility of hand opening strength and abduction range of motion (ROM) measurements in patients with thumb CMC OA to establish the cutoff values scores for minimal detectable change. ⋯ Subjects with CMC OA exhibited decreased combined thumb abduction and index finger extension strength, reduced thumb abduction ROM, and increased pain sensitivity when compared with their healthy counterparts. The minimal detectable change score in this patient population was 0.23 to 0.25 kg/cm(2) for pain pressure threshold, 0.12 to 0.13 lb for opening force, and 1.24° to 1.46° for abduction ROM measurement.

ReviewManipulative and multimodal therapy for upper extremity and temporomandibular disorders: a systematic review.
The purpose of this study was to complete a systematic review of manual and manipulative therapy (MMT) for common upper extremity pain and disorders including the temporomandibular joint (TMJ). ⋯ The information from this study will help guide practitioners in the use of MMT, soft tissue technique, exercise, and/or multimodal therapy for the treatment of a variety of upper extremity complaints in the context of the hierarchy of published and available evidence.

Effects of thrust amplitude and duration of high-velocity, low-amplitude spinal manipulation on lumbar muscle spindle responses to vertebral position and movement.
Mechanical characteristics of high-velocity, low-amplitude spinal manipulations (HVLA-SMs) can vary. Sustained changes in peripheral neuronal signaling due to altered load transmission to a sensory receptor's local mechanical environment are often considered a mechanism contributing to the therapeutic effects of spinal manipulation. The purpose of this study was to determine whether variation in an HVLA-SM's thrust amplitude and duration alters the neural responsiveness of lumbar muscle spindles to either vertebral movement or position. ⋯ Relatively low-amplitude thrust displacements applied during an HVLA-SM produced sustained increases in the resting discharge of paraspinal muscle spindles regardless of the duration over which the thrust was applied. However, regardless of the HVLA-SM's thrust amplitude or duration, the responsiveness of paraspinal muscle spindles to vertebral movement and to a new vertebral position was not affected.

Test-retest reliability, repeatability, and sensitivity of an automated deformation-controlled indentation on pressure pain threshold measurement.
The purpose of this study was to construct a computerized deformation-controlled indentation system and compare its test-retest reliability, repeatability, and sensitivity with a manual algometer for pressure pain threshold (PPT) measurements. ⋯ Although computerized algometry offers the benefits of eliminating the effects of operator reaction time, operator anticipation, alignment error, and variation in indentation rate on PPT measurements, these results indicate that manual algometry using load-controlled strategy may be better than computerized deformation-controlled algometry in terms of test-retest reliability, repeatability, and sensitivity. Constant load-controlled indentation protocol may be more favorable for PPT measurements. Future computerized instrumentation for PPT measurements should adopt a load-controlled mechanism.

Intrasession and intersession reliability of postural control in participants with and without nonspecific low back pain using the Biodex Balance System.
The purpose of this study was to evaluate the reliability of the Biodex Balance System (BBS) (Biodex Medical Systems, Shirley, NY) in chronic low back pain (CLBP) patients and healthy individuals in various conditions of postural and cognitive difficulty. ⋯ Biodex Balance System stability indices appear to be reliable measures of postural control in the CLBP patients especially in more challenging conditions, such as when standing with eyes closed.
