Lumbar spinal stenosis (LSS) is a common spinal disorder that causes patients to assume a forward-trunk posture. Spinal alignment affects swing limb angles and stance limb muscle activities. Therefore, we investigated the effects of differences in step up (SU) and step down (SD) tasks on the kinematics of the trunk and swing limb as well as stance limb muscle coordination in patients with LSS.

Nine elderly female patients diagnosed with LSS were recruited for this study. The sagittal kinematics of the trunk and swing limb and isolated contraction ratio of the gluteus medius (GMed) and vastus lateralis (VL) during SU and SD tasks were measured using a motion analysis system and surface electromyography system.

Thoracic (17.71∘± 7.77∘) and spine angles (13.64∘± 11.34∘) as well as swing hip (48.48∘± 12.76∘) and pelvic angles (7.52∘± 10.33∘) were significantly greater during SU than SD (10.14∘± 8.41∘, 10.03∘± 11.03∘, 29.42∘± 10.57∘, 3.21∘± 10.11∘, all P< 0.05, respectively). The isolated contraction raticompensatory mechanisms to address swing hip and knee angles. Trunk position affected pelvic limb muscle coordination in the standing support limb. These findings demonstrate that SD are more challenging than SU for patients with LSS, possibly due to reduced ability to generate adequate leg extensor muscular output to safely control the motion of the body's center of mass. Therefore, trunk positions must be considered when patients with LSS undergo rehabilitation programs, particularly those involving SD or descending stairs, so that healthcare professionals can better assist patients with LSS. In addition, this study provides a background for further studies.
Musculoskeletal disorders in acromegaly compromise upper and lower limb activity. Corresponding changes can be better assessed by a functional capacity test incorporating multitasking, such as the Glittre Activities of Daily Living Test (GA-T).

To evaluate functional capacity in adults with acromegaly using the GA-T and to correlate functional capacity with hand function and health-related quality of life.

The GA-T was applied to 36 patients with acromegaly and an equal number of healthy individuals. PF-06826647 Additionally, participants completed the Acromegaly Quality of Life (AcroQoL) questionnaire and underwent a chronic pain assessment using a map of the human body, a hand function evaluation using the Cochin Hand Functional Scale (CHFS), and a handgrip strength test.

Relative to the comparison group, patients with acromegaly required more time to perform the GA-T, showed worse hand function, and reported that squatting to accomplish shelving tasks was the major difficulty. GA-T time was correlated with the AcroQoL global score, handgrip strength, and the CHFS (rs=-0.487, p= 0.002; rs=-0.369, p= 0.026; rs= 0.538, p= 0.0007, respectively).

Patients with acromegaly exhibited a reduced functional capacity as assessed by the GA-T. Additionally, an association was identified between the total GA-T time and both hand function and quality of life.

There are currently no reports of biomechanical changes in patients with forward head posture (FHP) that result in altered muscle activation throughout various functions with muscle activation response during diverse sleep postures.

This study investigated neck and back muscle activity in individuals with and without FHP during a maintained side-sleeping position by incorporating various pillow designs.

Thirty-four participants (i.e., 17 in each group) were enrolled. The muscle activity was investigated via surface electromyography during the use of three trial pillows orthopedic pillow, hollow pillow, and Thai neck support pillow.

With the application of all three trial pillow, the FHP group demonstrated significantly greater middle-lower trapezius muscle activity than the normal head posture group (p< 0.05). Sternocleidomastoid and upper trapezius (UT) muscle activity were similar between the two groups (p> 0.05). Only UT muscle activity was affected by variations in pillow design. In the normal group, no difference was observed in the muscle activity between all three pillows (p> 0.05).

Feasibly, the ability to appropriately modify a pillow configuration without creating undesired muscle activation was limited to those exhibiting FHP. Therefore, specially designed pillows or mattresses should be investigated in terms of their relevance to muscle fatigue and potential musculoskeletal pain in FHP patients.

The aim of this study was to compare the potential post-activation performance enhancement (PAPE) effects of two different warm-up strategies, involving dynamic stretching (DS) or heavy load leg press (HL) on several key physical qualities in tennis players.

Twenty-six elite male tennis players (age 19.22 ± 4.20 years; body mass 67.37 ± 8.19 kg; height 1.77 ± 0.07 m) performed both warm-ups, with 48-hours between protocols (DS and HL), performed in a randomized order. Pre- and post-tests included countermovement jump, 5-m and 10-m sprint, 5-0-5 agility test, and hip extension and flexion range-of-motion which were performed before and after DS and HL warm-up protocols.

The DS warm-up led to substantial improvements in 5-m and 10-m sprint, 5-0-5 agility test, countermovement jump, and also to higher hip flexion range-of-motion. The HL warm-up caused impairments in 5-m and 10-m sprints, but improvements in 5-0-5 agility test, countermovement jump and hip extension range-of-motion. Compared to HL, DS warm-up induced possibly to likely positive effects on 5-m and 10-m linear sprint performance, as well as in hip flexion range-of-motion. Nevertheless, no differences in performance improvements in 5-0-5 agility test, countermovement jump and hip extension range-of-motion were found when comparing DS and HL warm-up protocols.

DS seems to be more effective than HL when performing a short warm-up protocol in elite tennis players.
