The Mean

Older adults who have survived cancer experience significantly more falls compared with healthy adults. Adult cancer survivors may also have a lower balance function than healthy adults. We examined muscle strength and balance function among 19 cancer survivors and 14 healthy subjects. The mean age of the cancer survivors was 51.5 ± 11.2 years; 6 men and 13 women. Cancer diagnoses included breast cancer, retroperitoneal sarcoma, acute leukemia, lung cancer, colorectal cancer, thyroid cancer, Ewing’s sarcoma, and tongue cancer. The mean age of healthy subjects was 47.4 ± 14 years; 3 men, 11 women. Muscle strength was assessed using hand grip and knee extensor strength tests. Balance function was evaluated using the Timed Up and Go (TUG) test, and body sway was tested using a force platform. No significant differences were found with respect to right and left grip strength or right and left knee extension strength between the 2 groups. A significantly higher TUG time was observed in cancer survivors than in healthy subjects ( P < .05). With eyes open, the area of the center of pressure was significantly larger in cancer survivors than in healthy subjects ( P < .05). Similarly, the length per area was significantly lower both with eyes open and closed for cancer survivors than for healthy subjects ( P < .05). TUG was significantly correlated with muscle strength in both groups ( P < .05). However, no body sway parameters were related to muscle strength in either group. Cancer survivors had lower balance function that might not have been related to muscle strength. Cancer survivors should be evaluated for balance function as there is a potential for impairment. The findings of this study will be relevant for planning the prevention of falls for cancer survivors.

Abstract Objectives　We aimed to investigate the differences as well as the relationship between muscle strength, balance function, quality of life (QOL), and fatigue in cancer survivors and healthy subjects. Design A cross-sectional observational study.Setting The Relay For Life Niigata in JapanParticipants Forty-one cancer survivors and 33 healthy subjects were included. Methods Muscle strength was evaluated via handgrip and knee extensor strength. Balance function was evaluated using the Timed Up and Go (TUG) test, and body sway was tested using a force platform. QOL was assessed using the Medical Outcome Study 36-item Short-Form Health Survey. Fatigue was measured using the brief fatigue inventory. Results Cancer survivors exhibited significantly decreased muscle strength, higher TUG, lower QOL, and higher fatigue than healthy subjects (P < 0.05). There were no significant differences between the two groups for any parameters of the body sway tests. There was a relationship between body sway test and QOL (P < 0.05) among cancer survivors. Additionally, some subscales for fatigue and QOL (P < 0.05) were related among cancer survivors; these relationships were stronger than those observed among healthy subjects. Conclusion Cancer survivors have the same balance function as healthy subjects despite a decrease in muscle strength. Cancer survivors initially tend to have decreased muscle strength, and thereafter worse balance function.

Abstract Objective To investigate the effect of visual fatigue caused by smart phone on the balance function. Subjects and Methods Forty subjects divided into 2 groups were included in the present study . Group I, twenty normal healthy subjects with mean age of 28.8 years. Group II, twenty subjects with a clinical diagnosis of peripheral vestibular disorder with mean age of 38.85years. They were subjected to a computer vision syndrome questionnaire (CVS-Q) , occulomotor tests of videonystagmography (VNG) and sensory organization test (SOT) of computerized dynamic posturography (CDP) before and after visual fatigue induction. Results Significant differences existed between C5, 6 and composite scores in group I and in C4 and composite scores in group II after visual fatigue induction. However, there was no significant difference between occulomotor tests in both groups after visual fatigue induction. Conclusions The smart phone use can affect the balance function in healthy subjects and augment the deficit in those with balance problem. Reducing visual fatigue should be considered through various procedures as taking proper rest, adjusting the brightness of screen, avoid any wrong posture and using filters if possible.

Minute Walk

The six-minute walk test (6MWT) is a widely used test for the indirect measurement of cardiorespiratory fitness in various cancer populations. Although the 6MWT is a simple test, there are no normative values for breast cancer survivors (BCS) or comparisons of results with healthy counterparts. A systematic review with a meta-analysis was carried out, which included studies from 2007 to 2020. Ninety-one studies were found, 21 of which were included in the quantitative synthesis. Among them were 9 randomized controlled trials (RCT), 8 prospective cohort studies and 4 cross-sectional studies. A total of 1084 BCS were included. Our results revealed that healthy subjects (n = 878) covered a significantly greater distance than BCS during the 6MWT (589.9 m vs. 477.4 m, p < 0.001), and the results of the meta-regression analysis showed that the 6MWD was predicted by the participants’ BMI (p < 0.001), but not by their age (p = 0.070). After adjustment for BMI, the healthy subjects also covered greater distances than the BCS (103 m; p < 0.001). The normative values of 6MWT were presented for BCS. Besides, 6MWT distances distinguish between their healthy counterparts, therefore, the 6MWT distance is a relevant parameter for the assessment and monitoring of cardiorespiratory fitness in medical and exercise interventions for BCS.

Biphasic Responses

ABSTRACT:Cutaneous reflexes in the upper limb were elicited by stimulating digital nerves and recorded by averaging rectified EMG from proximal and distal upper limb muscles during voluntary contraction. Distal muscles often showed a triphasic response: an inhibition with onset about 50 ms (Il) followed by a facilitation with onset about 60 ms (E2) followed by another inhibition with onset about 80 ms (12). Proximal muscles generally showed biphasic responses beginning with facilitation or inhibition with onset at about 40 ms. Normal ranges for the amplitude of these components were established from recordings on 22 arms of 11 healthy subjects. An attempt was made to determine the alterent fibers responsible for the various components by varying the stimulus intensity, by causing ischemic block of larger fibers and by estimating the afferent conduction velocities. The central pathways mediating these reflexes were examined by estimating central delays and by studying patients with focal lesions
