Body posture is one of the most important parts when lifting an object as it can causes injury if the wrong technique and body posture were used. A worker will injure their low back if a bad posture is not in consideration. A good body posture is recommended among workers to reduce the chance of injury while lifting and improve their postural safety. The main objectives of this study are to observe the body posture of the worker during lifting and study the comparison of using lower back support when lifting. It also investigates the muscle activity of the worker during heavy lifting using EMG and simulates the worker's movement using CATIA Software for Rapid Upper Limb Assessment (RULA) results. The selected grocery was chosen in Kota Samarahan, Sarawak with 7 male respondents are identified to undergo this study. The results show that the worker with lower back support tends to show raw EMG signal with lower muscle activity compared to without using lower back support. Thus, using belt support can reduce muscle activity by up to 67.4% compare to not wearing back support. Raw EMG signals also show 3010 amplitude (mV) muscle activity if postural safety of the workers improved by following the NIOSH lifting Recommendations.

Abstract Background: Many studies have attempted to clarify factors associated with the development of shoulder periarthritis. In its early stage, omalgia impairs normal, everyday life. Due to this pain, muscle force decreases in the affected side of the upper limb, and a change occurs in body composition distribution, especially in the upper limb. Currently, body composition distribution can be measured using dual energy X-ray absorptiometry (DEXA). Methods: 102 patients with unilateral shoulder pain over 3 months (5 males and 97 females, mean age: 62.5 ± 10.5 years) were assigned to the shoulder pain group (painful group). The control group consisted of 237 patients without shoulder pain (20 males and 197 females, mean age: 59.8 ±14.2 years). These factors were measured using a QDR-4500 DEXA scanner (Hologic Co., Ltd.). Results: Mean values of bone mineral density were 0.57 ±0.09 g/cm2 on the affected side and 0.59 ± 0.08 g/cm2 on the non-affected side in the painful group. Mean values in the control group were 0.57 ± 0.14 g/cm2 on the left side and 0.58 ±0.09 g/cm2 on the right side. There was no significant difference between the shoulder with and without pain, affected and non-affected side. Mean proportions of the upper limb that was fat were 40.1 ± 9.5% on the affected side and 35.7 ±9.8% on the non-affected side in the painful group. In the control group, the means were 39.2 ±11.1% on the left side and 37.5 ± 10.9% on the right side. The mean muscle masses of the upper limb were 1548.5 ±304.2 g on the affected side and 1723.5 ±321.5 g on the non-affected side in the painful group. There was a significant difference between the affected and non-affected side. Conclusions: We measured the body composition of the upper limb. Muscle mass of upper limb was significantly different between the affected and non-affected sides.

Abstract Introduction: Cerebral Palsy (CP) patients who have spastic hemiparesis usually present asymmetrical weight shift between the affected and non-affected side. Objective: To assess the effects of upper limb (UL) weight-bearing exercises on trunk symmetry, weight shift to the affected side and possible secondary effects on gait (speed and quality). Method: eleven participants with CP were randomized into two groups: Intervention Group (IG) and Control Group (CG); IG (n = 6) performed stretching exercises of the major muscle groups of UL and lower limbs (LL) and UL weight-bearing exercises in prone and seated position for 12 weeks. The CG (n = 5) did not undergo any kind of motor therapy during the study period but received the same exercises that IG after the study. The variables analyzed were: Gross Motor Function Measure (GMFM-88); Pediatric Berg Scale; Trunk Impairment Scale (TIS); Six-minute walking test (6MWT); Ten meters walking test (10MWT); Timed Up & Go (TUG); Edinburgh Visual Gait Scale (EVGS); and ground reaction force. Results: The IG showed improvement on 6MWT, TUG, TIS and Pediatric Berg Scale (p < 0.01), and CG showed improvement on GMFM-88 (p < 0.04) only for the intragroup analysis. Conclusion: The exercises were effective to improve static and dynamic balance, increasing gait speed and identifying a trend of improvement on body alignment and weight shift to the affected side.

Ayurveda in its principle has given importance to individualistic approach rather than generalize. Application of this examination can be clearly seem like even though two patients suffering from same disease, the treatment modality may change depending upon the results of Dashvidha Pariksha. Prakruti and Pramana both used in Dashvidha Pariksha. Both determine the health of the individual and Bala (strength) of Rogi (Patient). Ayurveda followed Swa-angula Pramana as the unit of measurement for measuring the different parts of the body which is prime step assessing patient before treatment. Sushruta and Charaka had stated different Angula Pramana of each Pratyanga (body parts). Specificity is the characteristic property of Swa-angula Pramana. This can be applicable in present era for example artificial limbs. A scientific research includes collection, compilation, analysis and lastly scrutiny of entire findings to arrive at a conclusion. Study of Pramana and its relation with Prakruti was conducted in 1000 volunteers using Prakruti Parkishan proforma with an objective of evaluation of Anguli Pramana in various Prakriti. It was observed co-relating Pramana in each Prakruti and Granthokta Pramana that there is no vast difference in measurement of head, upper limb and lower limb. The observational study shows closer relation of features with classical texts.

BACKGROUND: Recent clinical studies have revealed the advantages of using suspension devices. Although the supine, lateral, and forward leaning bridge exercises are low-intensity exercises with suspension devices, there is a lack of studies directly comparing exercise progression by measuring muscular activity and subjective difficulty. OBJECTIVE: To identify how the variations in the bridge exercise affects trunk muscle activity, the present study investigated changes in neuromuscular activation during low-intensity bridge exercises. We furthermore explored whether the height of the suspension point affects muscle activation and subjective difficulty. METHODS: Nineteen asymptomatic male participants were included. Three bridge exercise positions, supine bridge (SB), lateral bridge (LB), forward leaning (FL), and two exercise angles (15 and 30 degrees) were administered, thereby comparing six bridge exercise conditions with suspension devices. Surface electromyography and subjective difficulty data were collected. RESULTS: The rectus abdominis activity was significantly higher with the LB and FL exercises compared with the SB exercise (p< 0.05). The erector spinae muscle activity was significantly higher with the SB and LB exercises, compared with the FL exercise (p< 0.05). The LB exercise significantly increased the internal oblique muscle activity, compared with other exercise variations (p< 0.05). The inclination angle of the exercise only affected the internal oblique muscle and subjective difficulty, which were significantly higher at 30 degrees compared with 15 degrees (p< 0.05). CONCLUSIONS: Relatively higher inclination angle was not effective in overall activation of the trunk muscles; however, different bridge-type exercises could selectively activate the trunk muscles. The LB and SB exercises could be good options for stimulating the internal oblique abdominis, and the erector spinae muscle, while the FL exercise could minimize the erector spinae activity and activate the abdominal muscles.

BACKGROUND: Although the medial and lateral hamstrings are clearly distinct anatomically and have different functions in the transverse plane, they are often considered as one muscle during rehabilitation. OBJECTIVE: The purpose of the study was to compare the electromyographic (EMG) activity between the prone position and the supine position during maximal isometric contraction and to additionally confirm the effect of submaximal isometric contractions on EMG activity of medial and lateral hamstrings, and force. METHODS: In the prone position, EMG activities of the long head of biceps femoris (BFLH) and semitendinosus (ST) were measured during the maximal isometric contraction. In the supine position, hip extension force with EMG activity were measured during the maximal and the submaximal isometric contractions. RESULTS: EMG activity in the prone position was significantly decreased in the supine position. In the supine position, there was a significant difference between the BFLH and ST during the maximal isometric contraction, but not during the submaximal isometric contractions. CONCLUSIONS: The dependence on the hamstrings could be relatively lower during hip extensions. When the medial and lateral hamstrings are considered separately, the lateral hamstrings may show a more active response, with increased muscle length, in clinical practice.

In Part XII of this series (1921) the comparison was made of the intake and output of cholesterol in normal adults on a known diet and over periods of six days, and an average daily loss of 0·3 grm. of cholesterol was noted. The conclusion drawn was that there must be some organ in the body capable of synthesising cholesterol. A similar view has been put forward by Grigaut (1913), who expressed the opinion that this synthesis is the function of the suprarenal glands. It seemed likely that the study of the autolysis of various tissues under aseptic conditions might throw some light on this question. A number of observations bearing on this subject are described in the literature, some undertaken with the object of finding evidence of the presence of enzymes capable of hydrolysing cholesterol esters, others with the object of ascertaining whether destruction or synthesis of cholesterol took place on autolysis. The results are very conflicting.
