ABSTRACT
Introduction
We investigated and compared the effects of 2 different types of upper extremity exercise training on upper extremity function, strength, endurance, and ambulation in patients ...with early‐stage Duchenne muscular dystrophy (DMD).
Methods
The study group (n = 12) exercised with an arm ergometer under the supervision of a physiotherapist, whereas the control group (n = 12) underwent a strengthening range‐of‐motion (ROM) exercise program under the supervision of their families at home for 8 weeks. Upper extremity functional performance, strength, endurance, and ambulatory status were assessed before and after the training.
Results
Ambulation scores, endurance, and arm functions, as well as proximal muscle strength, were improved after the training in the study group (P < 0.05).
Conclusions
These results demonstrate that upper extremity training with an arm ergometer is more effective in preserving and improving the functional level of early‐stage DMD patients compared to ROM exercises alone. Muscle Nerve 51:697–705, 2015

A sedentary lifestyle has negative effects on many aspects of life.
The aim of this study was to determine the effects of physical activity on sleep quality, job satisfaction, and quality of life in ...office workers.
A convenience sample of office workers from administrative staff of a university was included. There were two groups; Group I did regular physical activity for at least eight weeks, and Group II did no regular physical activity. Sleep quality, job satisfaction, and quality of life were assessed using the Pittsburgh Sleep Quality Index, the Minnesota Job Satisfaction Scale, and the World Health Organization Quality-of-Life-Scale (WHOQOL-BREF), respectively.
Group I included 59 individuals and Group II 50 individuals. No significant differences were found between groups in terms of age, height, weight, and the period of time worked (p > 0.05). Although no significant difference was found in terms of sleep quality (p = 0.52), the overall job satisfaction of Group I was higher than Group II (p = 0.03). All subscales of the WHOQOL-BREF for Group I was higher than Group II (p < 0.05).
Regular physical activity could increase job satisfaction and quality of life for office workers. Further studies investigating the effect of physical activity in terms of its type, duration should be performed.

ABSTRACT
Background:
Muscle imaging methods such as ultrasound and magnetic resonance imaging have been used for many years to determine the dystrophic process in muscular dystrophies. However, the ...knowledge regarding muscle architecture in children at early-stage Duchenne muscular dystrophy (DMD) with different functional levels is limited.
Objective:
To explore the effect of functional level on muscle architectural properties in children with early stage DMD and the difference between DMD and typically developing (TD) peers.
Methods:
Thirty children with DMD (15 Grade 1 and 15 Grade 2 according to the Vignos Scale) and 5 TD peers were included. Ultrasound imaging was used to measure muscle thickness (MT), fascicle length (FL), and pennation angle (PA) of vastus lateralis (VL) and medial gastrocnemius (MG) muscles bilaterally.
Results:
The MT and FL values for VL, and MT, FL and PA values for MG muscles were higher in children with DMD compared with those of TD peers (p<0.05). The FL of VL, and MT and FL of GM muscles of children with DMD Grade 2 were higher than those of children with DMD Grade 1 (p<0.05).
Conclusions:
MT and FL are increased in children with DMD compared with TD peers. Additionally, muscle architecture seems to be affected even at the early stages of the disease.
Various studies have shown the efficacy of conventional isometric, Pilates and yoga exercises. However, data on the effects and comparison of these specific exercises on the cervical muscle ...morphology are insufficient or lacking.
To investigate the effects of different exercise treatments on neck muscles in patients with chronic neck pain.
A randomized study.
Fifty-six patients with chronic neck pain were randomized into 3 groups as follows: Pilates group (n = 20), yoga group (n = 18) and isometric group (n = 18). Demographics and background information were recorded. The thickness and cross-sectional area of neck muscles were evaluated by ultrasound imaging. Cervical motions were measured with a goniometer. Pain severity was evaluated with the McGill Pain Scale, disability with the Neck Disability Index, quality of life with the Nottingham Health Profile, and emotional status with the Beck Depression Inventory. In addition to a conventional physio-therapy programme, 15 sessions of physical therapy, including hot pack, ultrasound, and transcutaneous electrical nerve stimulation (TENS), were provided to all patients. All groups performed the exercises for 6 weeks. The aforementioned assessments were performed before and 6 weeks after the treatment.
Although pain, disability, depression and quality of life improved similarly within all groups (all p < 0.05), muscle thickness values as regards the semispinalis capitis were increased only in the Pilates group (p = 0.022).
The lack of complex (progressive resistive) exercise treatment protocols, short treatment duration and partial supervision.
All 3 types of exercise had favourable effects on pain and functional scores, but no differences were found among the groups, except for the Pilates group, in which the semispinalis capitis muscle increased in thickness.
To investigate the effects of lower limb flexibility on the functional performance of children with Duchenne muscular dystrophy.
Thirty children, whose functional levels were at 1 or 2 according to ...the Brooke Lower Extremity Functional Classification Scale, were included in this study. The flexibilities of the hamstrings, hip flexors, tensor fascia latae, and gastrocnemius muscles were evaluated in the children's dominant lower limbs. The children's functional performance was assessed using 6-minute walk tests and timed performance tests. The correlations between the flexibilities of the lower limb muscles and the performance tests were examined.
The flexibilities of the lower extremity muscles were found to be correlated to the 6-minute walk tests and the timed performance tests. The flexibility of the hamstrings (r = -.825), the gastrocnemius muscles (r = .545), the hip flexors (r = .481), and the tensor fascia latae (r = .445) were found to be correlated with functional performance as measured by the 6-minute walk tests (P < .05).
The results of the current study indicate that the flexibility of the lower limbs has an effect on functional performance in the early stages of Duchenne muscular dystrophy. More research is needed to determine the functional effects of flexibility on performance by adding long-term flexibility exercises to the physiotherapy programs of children with Duchenne muscular dystrophy.
This study aims to investigate the feasibility and safety of short-term functional electrical stimulation (FES) training of the quadriceps femoris muscles in a child with facioscapulohumeral muscular ...dystrophy (FSHD).
A 7-year-old child with FSHD received treatment due to a decrease in functional performance and difficulty climbing stairs. The child was followed up with a home-based exercise program. FES was applied twice a week during stair climbing for six weeks. Muscle activation of the quadriceps femoris was measured using superficial electromyography, muscle strength was measured with a hand-held dynamometer, and functional performance was assessed with the 6-Minute Walk and the Stair Climb Tests before and after the treatment period.
At the end of the treatment, there was an improvement in muscle activation. While muscle strength increased in the quadriceps femoris muscle of the non-dominant side, it remained constant on the dominant side. Functional performance test results also improved.
FES was a feasible and safe tool to use in our case, a child with FSHD.

The aim of this study was to compare exercise intensity of active video games (AVGs) between hip- and wrist-worn accelerometer data in cerebral palsy (CP).
Twenty children and adolescents ...(9.35 ± 3.71 years) with CP performed two exercise sessions, completing a standardized series of AVGs. Exercise intensity was collected, while one accelerometer was fitted to wrist and hip in separate, counterbalanced sessions.
Accelerometer counts per minute and cut-points determined were significantly different between the wrist- and hip-worn outputs (p < .001). Metabolic equivalents (METs) of performing AVGs exceeded the three METs moderate intensity threshold in wrist-worn (3.12 ± 0.86) accelerometer and hip-worn data tend to underestimate intensity (1.16 ± 0.08).
Previous studies showed METs required to perform AVGs were related to moderate intensity (3-6 METs) in CP with mild deficits. Wrist-worn accelerometer, exceeding 3 METs, seem to have higher accuracy in measuring exercise intensity of AVGs than hip-worn.
