ABSTRACT

BACKGROUND: Thermal detection thresholds and thermal pain thresholds are important in quantitative sensory testing. Although they have been well studied for assessing somatosensory function, the investigation of thermal pain tolerance has been insufficient. The aim of this study was to explore the characteristics of thermal pain tolerance and pain ratings in healthy subjects. METHODS: Cold pain tolerance (CPTol) and heat pain tolerance (HPTol) were tested in 213 healthy adults aged 18-81 years recruited from the local community. The thermal detection and thermal pain thresholds were also tested to investigate the association with pain tolerance. The visual analogue scale (VAS) was used for assessing pain severity immediately after the thermal pain and tolerance tests. RESULTS: The normality of the CPTol and HPTol was acceptable. Most participants rated the pain induced by the CPTol and HPTol testing as moderate. HPTol was lower in women than in men (p = 0.001), but CPTol did not differ between sexes. The pain ratings of CPTol and HPTol did not differ between sexes, but significant age effects were observed. The association of the tolerance temperature with pain ratings was weak, while those of pain ratings for CPTol and HPTol were strong (r = 0.87). CONCLUSIONS: Women were more sensitive to tolerance heat pain stimuli. Younger participants reported more pain for thermal pain and tolerance tests. SIGNIFICANCE: Thermal pain tolerance and pain rating for the thermal pain tolerance temperature depend on gender and age. Women are more sensitive to heat temperatures, young people rate more pain, and the pain ratings of heat and cold are strongly correlated.

ABSTRACT

Facioscapulohumeral muscular dystrophy (FSHD) is a slowly progressive myopathy with autosomal dominant inheritance remarkable for its early involvement of facial musculature. The purpose of our study was to assess the rate of strength deterioration, functional condition and performance of activity of daily living of patients with FSHD in Taiwan. Twenty patients diagnosed with FSHD were included in this study. Manual muscle testing (MMT) was used to evaluate muscle strength. The Brooke and Vignos scales were used to assess upper and lower extremity function respectively, and the capability of the activity of daily living was measured by Barthel index. The result of the strength testing was characterized by the presence of a progressive asymmetrical muscular weakness in patients with FSHD. The mean muscular strength of the right extremity was weaker than its left counterparts (p < 0.05) and the shoulder muscle group was the weakest. According to the Brooke functional scale, 20% of our patients were graded as 1, 30% as grade 2, and 50% as grade 3. On the Vignos functional scale, 50% of patients fell into grade 1, 10% in grade 2, and 40% in grades 3-5. Vignos scale was significantly correlated with mean muscle strength (p < 0.05). The average value of Barthel index was 97.8 +/- 4.7. The muscle strength decline in this Taiwanese of FSHD population was more severe in shoulder girdle area. The mean muscle strength of the right extremity was weaker than the left. Most of our patients suffered from mild or moderate physical disability. Finding of these Taiwanese FSHD population is similar to those reported elsewhere in the world.

ABSTRACT

This study was design to reach a better understanding of muscle strength, motor function and activity of daily living in patients of limb-girdle muscular dystrophy. Forty-eight patients diagnosed as cases of limb-girdle muscular dystrophy were included in this study. Manual muscle testing was used to evaluate muscle strength. The Brooke and Vignos scales were used to grade upper and lower extremities function, respectively, and the ability of daily living activity was measured by Barthel index. Our patients showed progressive symmetrical limb-girdle muscular weakness. Upon regression analysis we found that mean muscle strength was inversely related to disease duration (years) as follows: mean muscle strength = 0.6052 + (0.6309/disease duration). According to the Brooke functional scale, 89.6% of our patients were graded as 1-3 and 10.4% were graded as 5. On the Vignos functional scale, 79.1% of patients fell into the grades 1-5, one person (2.1%) in grade 6 and 18.8% in grade 9 category. The average Barthel index was 85.3 +/- 20.7. Mean muscle strength was significantly correlated with the average Barthel, Vignos and Brooke functional scales. Our study could offer the strength and functional performance of limb-girdle muscular dystrophy on natural history. The muscle strength declined in Taiwanese patients of limb-girdle muscular dystrophy in a typical pattern. Regression analysis showed that the strength was inversely related to disease duration. These findings demonstrate that most of our patients suffered from mild or moderate physical disability.

ABSTRACT

Many factors such as anthropometric variables influence strength performance. This study is to determine the relationship between knee isokinetic strength and body composition, and to compare the gender differences. Test-retest reliability had been performed within one week for all measurement methods before the formal study. Fifty-eight 20-25 year-old university students, 32 females and 26 males, participated in this study. Isokinetic strength of the knee flexion and extension was measured at two angular velocities of 60 degrees/sec and 120 degrees/sec. Body composition was measured by bioelectrical impedance analysis (BIA) and skinfold caliper. The others variables including height, body weight, body mass index (BMI), and waist to hip ratio were measured or calculated. The results showed that the intra-class correlation coefficients for isokinetic knee strength were between 0.83 and 0.93, and body composition and anthropometric variables were between 0.83 and 0.98. Isokinetic knee strength was significantly correlated with body height, body weight, BMI, waist and hip ratio and percent of body fat estimated by skinfold caliper (r = -0.56 to 0.64). The correlation between isokinetic strength with percent of body fat estimated by BIA (r = -0.60 to -0.74; p < 0.001) and with fat free mass (r = 0.64 to 0.78; p < 0.001) was even higher. Although male subjects had significantly greater mean values in body height, body weight, waist to hip ratio and isokinetic strength than female subjects, the MANCOVA showed that the effect of gender on knee isokinetic strength would be eliminated when the covariant variable, the percent of body fat measured by BIA and BMI was controlled in the analysis model. In conclusion, knee isokinetic strength was significantly negatively correlated with proportion of fat and positively correlated with fat free mass. The magnitude of strength difference between males and females could be explained by differences in body fat proportion and BMI in this study. Therapist would take the body fat composition, fat free mass, and BMI into consideration in knee muscle strength measurement. Less body fat and higher BMI will contain more fat free mass that produces more muscle strength.

ABSTRACT

The purpose of this study was to reach a better understanding the deficits of activity of daily living (ADL) skills in patients with Duchenne muscular dystrophy (DMD), and their influencing factors. Our samples consisted of 35 male DMD patients, aged 3-24 years. The Barthel index was used to assess daily living abilities. Besides ten different motor abilities, muscle strengths of both upper and lower extremities and joint contractures were also included in each patient's evaluation. The results of degree of severity in ADL performance showed that 21.1% of patients were classified as totally dependent, 48.5% were severely dependent, 12.1% moderately dependent, 9.1% mildly dependent and 9.1% totally independent. Among the ADL skills, the bathing needed most assistance whereas feeding required the least. Two of the sixteen factors influencing ADL performance was calculated to be significant after stepwise multiple regression analysis. They were hip contracture and static sitting balance. In conclusion, we find that DMD patients are highly dependent in carrying out ADL tasks. Therefore, it is very important to avoid contracture, to increase static sitting balance and to use appropriate devices to improve their daily living abilities. Finally, the Barthel index proved acceptable in evaluating Taiwanese children over six years of age.

ABSTRACT

Duchenne muscular dystrophy (DMD) is a disease of progressive muscular weakness and wasting. This study is designed to evaluate the muscle strength and functional performance of patients with DMD during the natural progression of this disease. This study comprises a sample of 35 subjects who were confirmed to have DMD. Manual muscle testing (MMT) was used to evaluate muscle strength, the Brooke functional scale to rate the motor function of the upper extremity, and the Vignos functional scale to rate the motor function of the lower limbs. The results showed a significant positive correlation between age and the decrement in strength, i.e. a one year increment in age led to a 3.9% decrease in the average muscle strength. The strength loss always occurred in a typical pattern proceeding from the lower extremities to the upper extremities, and from the proximal to the distal parts. There was a significant negative correlation between muscle strength and both the Brooke and Vignos functional scales. These findings may suggest that decreased muscle strength results in a progressive worsening of the functional performance of the extremities. In addition, the Brooke scale is significantly correlated with the Vignos scale through the natural course of DMD. The high percentage (90.5%) of subjects without the long leg braces needed for ambulation indicates an inadequate rehabilitation care for DMD patients in this country.
