RESUMO
PURPOSE: Low levels of physical activity often observed in pediatric oncology might be attributed to various functional deficits, especially those of the lower limbs as these affect gait, mobility, and, consequently, physical activity. In the past few years, whole-body vibration (WBV) has emerged as a new therapy modality for improving physical functioning. Although WBV is increasingly applied in children with disabilities, its impact on lower limb function in pediatric cancer patients and survivors has not yet been investigated. METHODS: To establish whether there is evidence that WBV may be beneficial for pediatric cancer patients and survivors, this review summarizes current data on WBV studies among children with disabilities and extracts relevant information for the pediatric cancer population. Two independent reviewers performed a systematic literature search following the PRISMA guidelines. RESULTS: Nine studies were included in the analysis. Results demonstrate that WBV is a safe, highly compliant, and effective approach in cohorts of children with disabilities. The largest effects of WBV were observed in lower extremity muscle mass and strength, balance control, gait, and walking ability. Furthermore, we were able to develop first recommendations for WBV protocols. CONCLUSIONS: WBV seems to be feasible and effective for improving parameters that may be relevant to the pediatric cancer population. Efforts are needed to conduct first WBV interventions in children with cancer proving the effects. The developed recommendations for WBV protocols might help to implement these intervention studies.

Chemotherapy-induced peripheral neuropathy (CIPN) is a prevalent and clinically relevant side effect of chemotherapy. The symptoms diminish patients' quality of life and represent a decisive limiting factor for medical therapy. To date, effective treatment options are lacking. Specific exercise interventions have proven promising to target relevant symptoms. We conducted a prospective, four-armed, randomized, controlled trial, to evaluate the effects of sensorimotor training (SMT) and whole-body vibration training (WBV) on patients with CIPN. Participants (N = 40) were randomized to either one of two intervention groups (SMT N = 10 or WBV N = 10) or oncological control group (N = 10) and matched by gender and age with a healthy control (N = 10). The intervention groups exercised twice a week for 6 weeks. Primary endpoint was the reduction of CIPN-related symptoms (improve peripheral deep sensitivity, Achilles tendon reflex (ASR) and patellar tendon reflex (PSR), light-touch perception, sense of position, and lower leg strength). Secondary endpoints were nerve conduction velocity and amplitude, balance control, quality of life, and CIPN-related pain. Patients exercising improved sensory and associated motor symptoms. Significant intergroup differences were found for the tendon reflexes (ASR P = .017 and PSR P = .020), peripheral deep sensitivity (P = .010), and pain (P = .043). Furthermore, tendencies were found regarding the subjective improvement of symptoms (P = .075) and two subscales of the EORTC-QLQ-C30 questionnaire: pain (P = .054) and dyspnea (P = .054). The results for the SMT group were superior regarding the tendon reflexes, and a tendency regarding the subjective report of symptoms, while WBV was superior regarding pain. SMT and WBV behold a large potential to reduce CIPN-related symptoms and can be considered feasible and safe for patients with CIPN (compliance 97.5%, no adverse events).Registration: DRKS00013027.

BACKGROUND: Although people with haematological malignancies have to endure long phases of therapy and immobility, which is known to diminish their physical performance level, the advice to rest and avoid intensive exercises is still common practice. This recommendation is partly due to the severe anaemia and thrombocytopenia from which many patients suffer. The inability to perform activities of daily living restricts them, diminishes their quality of life and can influence medical therapy. OBJECTIVES: In this update of the original review (published in 2014) our main objective was to re-evaluate the efficacy, safety and feasibility of aerobic physical exercise for adults suffering from haematological malignancies considering the current state of knowledge. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library, 2018, Issue 7) and MEDLINE (1950 to July 2018) trials registries (ISRCTN, EU clinical trials register and clinicaltrials.gov) and conference proceedings. We did not apply any language restrictions. Two review authors independently screened search results, disagreements were solved by discussion. SELECTION CRITERIA: We included randomised controlled trials (RCTs) comparing an aerobic physical exercise intervention, intending to improve the oxygen system, in addition to standard care with standard care only for adults suffering from haematological malignancies. We also included studies that evaluated aerobic exercise in addition to strength training. We excluded studies that investigated the effect of training programmes that were composed of yoga, tai chi chuan, qigong or similar types of exercise. We also excluded studies exploring the influence of strength training without additive aerobic exercise as well as studies assessing outcomes without any clinical impact. DATA COLLECTION AND ANALYSIS: Two review authors independently screened search results, extracted data and assessed the quality of trials. We used risk ratios (RRs) for adverse events, mortality and 100-day survival, standardised mean differences (SMD) for quality of life (QoL), fatigue, and physical performance, and mean differences (MD) for anthropometric measurements. MAIN RESULTS: In this update, nine trials could be added to the nine trials of the first version of the review, thus we included eighteen RCTs involving 1892 participants. Two of these studies (65 participants) did not provide data for our key outcomes (they analysed laboratory values only) and one study (40 patients) could not be included in the meta-analyses, as results were presented as changes scores only and not as endpoint scores. One trial (17 patients) did not report standard errors and could also not be included in meta-analyses. The overall potential risk of bias in the included trials is unclear, due to poor reporting.The majority of participants suffered from acute lymphoblastic leukaemia (ALL), acute myeloid leukaemia (AML), malignant lymphoma and multiple myeloma, and eight trials randomised people receiving stem cell transplantation. Mostly, the exercise intervention consisted of various walking intervention programmes with different duration and intensity levels.Our primary endpoint overall survival (OS) was only reported in one of these studies. The study authors found no evidence for a difference between both arms (RR = 0.67; P = 0.112). Six trials (one trial with four arms, analysed as two sub-studies) reported numbers of deceased participants during the course of the study or during the first 100 to 180 days. For the outcome mortality, there is no evidence for a difference between participants exercising and those in the control group (RR 1.10; 95% CI 0.79 to 1.52; P = 0.59; 1172 participants, low-certainty evidence).For the following outcomes, higher numbers indicate better outcomes, with 1 being the best result for the standardised mean differences. Eight studies analysed the influence of exercise intervention on QoL. It remains unclear, whether physical exercise improves QoL (SMD 0.11; 95% CI -0.03 to 0.24; 1259 participants, low-certainty evidence). There is also no evidence for a difference for the subscales physical functioning (SMD 0.15; 95% CI -0.01 to 0.32; 8 trials, 1329 participants, low-certainty evidence) and anxiety (SMD 0.03; 95% CI -0.30 to 0.36; 6 trials, 445 participants, very low-certainty evidence). Depression might slightly be improved by exercising (SMD 0.19; 95% CI 0.0 to 0.38; 6 trials, 445 participants, low-certainty evidence). There is moderate-certainty evidence that exercise probably improves fatigue (SMD 0.31; 95% CI 0.13 to 0.48; 9 trials, 826 patients).Six trials (435 participants) investigated serious adverse events. We are very uncertain, whether additional exercise leads to more serious adverse events (RR 1.39; 95% CI 0.94 to 2.06), based on very low-certainty evidence.In addition, we are aware of four ongoing trials. However, none of these trials stated, how many patients they will recruit and when the studies will be completed, thus, potential influence of these trials for the current analyses remains unclear. AUTHORS' CONCLUSIONS: Eighteen, mostly small RCTs did not identify evidence for a difference in terms of mortality. Physical exercise added to standard care might improve fatigue and depression. Currently, there is inconclusive evidence regarding QoL, physical functioning, anxiety and SAEs .We need further trials with more participants and longer follow-up periods to evaluate the effects of exercise intervention for people suffering from haematological malignancies. To enhance comparability of study data, development and implementation of core sets of measuring devices would be helpful.

BACKGROUND: Chemotherapy-induced peripheral neuropathy (CIPN) is a common and clinically relevant side effect of chemotherapy. Approximately 50% of all leukemia, lymphoma, colorectal- and breast cancer patients are affected. CIPN is induced by neurotoxic chemotherapeutic agents and can manifest with sensory and/or motor deficits. It is associated with significant disability and poor recovery. Common symptoms include pain, altered sensation, reduced or absent reflexes, muscle weakness, reduced balance control and insecure gait. These symptoms not only affect activities of daily living, subsequently reducing patients' quality of life, they have far more become a decisive limiting factor for medical therapy, causing treatment delays, dose reductions, or even discontinuation of therapy, which can affect the outcome and compromise survival. To date, CIPN cannot be prevented and its occurrence presents a diagnostic dilemma since approved and effective treatment options are lacking. Promising results have recently been achieved with exercise. We have revealed that sensorimotor training (SMT) or whole body vibration (WBV) can reduce the symptoms of CIPN and attenuate motor and sensory deficits. We furthermore detected a tendency that it may also have a preventive effect on the onset of CIPN. METHODS: We are therefore conducting a prospective, multicentre, controlled clinical trial involving 236 oncological patients receiving either oxaliplatin (N = 118) or vinca-alkaloid (N = 118) who are randomized to one of two interventions (SMT or WBV) or a treatment as usual (TAU) group. Primary endpoint is the time to incidence of neurologically confirmed CIPN. Secondary endpoints are pain, maintenance of the functionality of sensory as well as motor nerve fibres as well as the level of physical activity. The baseline assessment is performed prior to the first cycle of chemotherapy. Subsequent follow-up assessments are conducted at 12 weeks, after completion of chemotherapy, and at a 3-month follow-up. Patients who develop CIPN receive an additional assessment at this time point, as it represents the primary endpoint. DISCUSSION: We hypothesize that SMT and WBV prevent the onset or delay the progression of CIPN, decrease the likelihood of dose reductions or discontinuation of cancer treatment and improve patients' quality of life.

PURPOSES: Physical activity is supposed to decrease mortality of colorectal cancer (CRC) and is suggested to reduce side-effects of the disease and its treatment. However, the knowledge about the influence of exercise interventions on patients suffering from CRC and metastasized CRC (mCRC) is still sparse. One frequently observed side effect in mCRC is chemotherapy-induced peripheral neuropathy (CIPN). This randomized controlled trial investigated the influence of a supervised exercise program on CIPN in mCRC. METHODS: Thirty patients (stage IV) undergoing outpatient palliative treatment including a median of 23.5 chemotherapy cycles of various regimens were randomly assigned to an intervention or control group (IG, n = 17; CG, n = 13). The IG participated in an eight-week supervised exercise program, including endurance, resistance and balance training (2×/week for 60 min) whereas the CG received written standard recommendations to obtain physical fitness. CIPN was assessed using the FACT/GOG-NTX questionnaire. Moreover, endurance capacity (6MWT), strength (h1RM) and balance (GGT-Reha) were evaluated before (t 0) and after (t 1) the intervention as well as after 4 weeks follow-up (t2). RESULTS: Neuropathic symptoms remained stable in the IG over time, while CIPN significantly worsened in the CG from t 0 to t 1 and t 0 to t 2. In contrast to the CG, the IG significantly improved in strength and balance function. Changes in CIPN correlated with changes in balance. CONCLUSIONS: This is the first investigation showing positive effects of a multimodal exercise program on CIPN, balance and strength on mCRC patients in a palliative setting, thereby consequently increasing patients` quality of life. The results support earlier findings stating a positive influence of balance exercise on CIPN.

PURPOSE: To assess a whole-body vibration (WBV) intervention for children after cancer treatment. METHODS: Eleven children after inpatient anticancer therapy participated in a 12-week supervised WBV intervention, which consisted of one 9- to 13-minute WBV session per week, with 5 to 9 minutes' overall vibration time. Feasibility was defined as the ability to participate in WBV training without reporting adverse events. The number of offered and completed training sessions, program acceptance, and measures of function were assessed. RESULTS: Nine participants completed the WBV intervention without any WBV-related adverse events. The adherence rate was 87.96%. Only minor side effects were reported and there was general program acceptance. We found indications that WBV has positive effects on knee extensor strength and active ankle dorsiflexion range of motion. CONCLUSIONS: WBV was feasible, safe, and well received among children after inpatient anticancer therapy. No health deteriorations were observed. Positive effects need to be confirmed in future trials.

SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, 2014, Issue 1) and MEDLINE (1950 to January 2014) as well as conference proceedings for randomised controlled trials (RCTs). SELECTION CRITERIA: We included RCTs comparing an aerobic physical exercise intervention, intending to improve the oxygen system, in addition to standard care with standard care only for adults suffering from haematological malignancies. We also included studies that evaluated aerobic exercise in addition to strength training.

DATA COLLECTION AND ANALYSIS: Two review authors independently screened search results, extracted data and assessed the quality of trials. We used risk ratios (RRs) for adverse events and 100-day survival, standardised mean differences for quality of life (QoL), fatigue, and physical performance, and mean differences for anthropometric measurements. MAIN RESULTS: Our search strategies identified 1518 potentially relevant references. Of these, we included nine RCTs involving 818 participants. The potential risk of bias in these trials is unclear, due to poor reporting.The majority of participants suffered from acute lymphoblastic leukaemia (ALL), acute myeloid leukaemia (AML), malignant lymphoma and multiple myeloma, and six trials randomised people receiving stem cell transplantation. Mostly, the exercise intervention consisted of various walking intervention programmes with different duration and intensity levels.Our primary endpoint of overall survival (OS) was not analysed in any of the included trials, but three trials reported deceased participants during the course of the study or during the first 100 days. There is no evidence for a difference between participants exercising and those in the control group (RR 0.93; 95% CI 0.59 to 1.47; P = 0.75; 3 trials, 269 participants, moderate quality of evidence).Four trials analysed the influence of exercise intervention on quality of life (QoL). Excluding one trial with serious baseline imbalances, physical exercise improves QoL (SMD 0.26; 95% CI 0.03 to 0.49; P = 0.03; 3 trials, 291 participants, low quality of evidence). This positive effect of exercise was also found in the subscales physical functioning (SMD 0.33; 95% CI 0.13 to 0.52; P = 0.0009; 4 trials, 422 participants, moderate quality of evidence) and depression (SMD 0.25; 95% CI -0.00 to 0.50; P = 0.05; 3 trials, 249 participants, low quality of evidence). However, there is no evidence for a difference between additional exercise and standard treatment for the subscale anxiety (SMD -0.18; 95% CI -0.64 to 0.28; P = 0.45; 3 trials, 249 participants, low quality of evidence). Seven trials (692 participants) evaluated fatigue. There is moderate quality of evidence that exercise improves fatigue (SMD 0.24; 95% CI 0.08 to 0.40; P = 0.003).Eight studies evaluated various aspects of physical performance (e.g. aerobic capacity, cardiovascular fitness), but none of them could be pooled in a meta-analysis. In seven trials there is a tendency or statistically significant effect favouring the exercise group (very low quality of evidence).Three trials (266 participants) investigated serious adverse events (SAEs) (e.g. bleeding, fever, pneumonia, deep vein thrombosis, and infection), and one trial (122 participants) assessed adverse events (AEs). There is no evidence for a difference between arms in terms of SAEs (RR 1.44; 95% CI 0.96 to 2.18; P = 0.06) or AEs (RR 7.23; 95% CI 0.38 to 137.05; P = 0.19); both findings are based on low quality of evidence. AUTHORS' CONCLUSIONS: There is no evidence for differences in mortality between the exercise and control groups. Physical exercise added to standard care can improve quality of life, especially physical functioning, depression and fatigue. Currently, there is inconclusive evidence regarding anxiety, physical performance, serious adverse events and adverse events.We need further trials with more participants and longer follow-up periods to evaluate the effects of exercise intervention for people suffering from haematological malignancies. Furthermore, we need trials with overall survival as the primary outcome to determine whether the suggested benefits will translate into a survival advantage. To enhance comparability of study data, development and implementation of core sets of measuring devices would be helpful.

Importance: Chemotherapy-induced peripheral neuropathy (CIPN) is a highly prevalent and clinically relevant adverse effect of chemotherapy, negatively impacting patient quality of life. The lack of effective preventive or therapeutic options regarding CIPN often requires changes in cancer therapy, potentially resulting in reduced survival. Objective: To determine whether sensorimotor training (SMT) and whole-body vibration (WBV) training reduce symptoms and decrease the onset of CIPN. Design, Setting, and Participants: This prospective multicenter randomized clinical trial (STOP) followed up patients over 5 years at 4 centers in or near Cologne, Germany. Patients undergoing treatment with oxaliplatin or vinca alkaloids were recruited. Participants were recruited from May 2014 to November 2020. Data were last analyzed in June 2021. Interventions: Participants in the intervention groups performed supervised SMT or WBV training sessions twice a week, each lasting approximately 15 to 30 minutes, concomitant to medical therapy. Main Outcomes and Measures: The primary end point was the incidence of CIPN. Secondary end points included subjective neuropathy symptoms, balance control, physical activity levels, quality of life, and clinical outcome. For cross-stratum evaluations, the Mantel-Haenszel test (MH) was used, and within individual strata, Fisher exact test was used for analysis. Results: A total of 1605 patients were screened, and 1196 patients did not meet all inclusion criteria, with 251 further excluded or declining participation. A total of 158 patients (mean [SD] age, 49.1 [18.0-82.0] years; 93 [58.9%] male) were randomized into 1 of 3 groups: 55 (34.8%) in SMT, 53 (33.5%) in WBV, and 50 (31.6%) in treatment as usual (TAU). The incidence of CIPN in participants was significantly lower in both intervention groups compared to the control group (TAU): (SMT, 12 of 40 [30.0%; 95% CI, 17.9%-42.1%] and WBV, 14 of 34 [41.2%; 95% CI, 27.9%-54.5%] vs TAU, 24 of 34 [70.6%; 95% CI, 58.0%-83.2%]; P = .002 for intention to treat-MH). Patients receiving vinca alkaloids and performing SMT benefited the most. Results were more pronounced in a per-protocol analysis (>75% participation in the intervention) (SMT, 8 of 28 [28.6%; 95% CI, 16.6%-40.5%] and WBV, 9 of 24 [37.5%; 95% CI, 24.4%-50.5%] vs TAU, 22 of 30 [73.3%; 95% CI, 61.6%-85.6%]). Improvements in favor of SMT compared to TAU were found for balance control bipedal with eyes open; bipedal with eyes closed; monopedal, vibration sensitivity, sense of touch, lower leg strength, pain reduction, burning sensation, chemotherapy dose reductions, and mortality. Conclusion and Relevance: This randomized clinical trial provides initial evidence that neuromuscular training decreases the onset of CIPN.

INTRODUCTION: Peripheral neuropathies are a prevalent, heterogeneous group of diseases of the peripheral nervous system. Symptoms are often debilitating, difficult to treat, and usually become chronic. Not only do they diminish patients' quality of life, but they can also affect medical therapy and lead to complications. To date, for most conditions there are no evidence-based causal treatment options available. Research has increased considerably since the last review in 2014 regarding the therapeutic potential of exercise interventions for patients with polyneuropathy. OBJECTIVE: Our objective in this systematic review with meta-analysis was to analyze exercise interventions for neuropathic patients in order to update a systematic review from 2014 and to evaluate the potential benefits of exercise on neuropathies of different origin that can then be translated into practice. METHODS: Two independent reviewers performed a systematic review with meta-analysis according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Inclusion criteria according to the PICOS approach were: neuropathic patients, exercise interventions only, an inactive or non-exercising control group, and solely randomized controlled trials with the following outcome parameters: neuropathic symptoms, balance parameters, functional mobility, gait, health-related quality of life, and HbA1c (glycated hemoglobin). RESULTS: A total of 41 randomized, controlled trials met all inclusion criteria, 20 of which could be included in the quantitative analysis. Study quality varied from moderate to high. Current data further support the hypothesis that exercise is beneficial for neuropathic patients. This is best documented for patients with diabetic peripheral neuropathy (DPN) (27 studies) as well as for chemotherapy-induced peripheral neuropathy (CIPN) (nine studies), while there are only few studies (five) on all other causes of neuropathy. We found standardized mean differences in favor of the exercise group of 0.27-2.00 for static balance, Berg Balance Scale, Timed-up-and-go-test, nerve conduction velocity of peroneal and sural nerve as well as for HbA1c in patients with DPN, and standardized mean differences of 0.43-0.75 for static balance, quality of life, and neuropathy-induced symptoms in patients with CIPN. CONCLUSION: For DPN, evidence-based recommendations can now be made, suggesting a combination of endurance and sensorimotor training to be most beneficial. For patients with CIPN, sensorimotor training remains the most crucial component. For all other neuropathies, more high-quality research is needed to derive evidence-based recommendations. Overall, it seems that sensorimotor training has great potential to target most neuropathies and combined with endurance training is therefore currently the best treatment option for neuropathies.

INTRODUCTION: The widespread prevalence of type 2 diabetes (T2D) not only influences patients' daily lives but also has an economic impact on society. Increasing physical activity and a healthy diet can delay the progression of T2D. Although there are evidence-based recommendations on diet and physical activity, patients with T2D have difficulties implementing them. An appropriate lifestyle intervention can address this problem. METHODS AND ANALYSIS: This study is based on the need to develop an intervention that helps patients to establish behavioural changes in order to achieve glycaemic control. The intervention will be evaluated in a monocentric, open-label, pragmatic, two-arm randomised controlled trial with a sample ratio of 1:1 and a parallel design. This superiority study will be conducted in Switzerland. All enrolled patients (n=90) will receive the standard medical treatment for T2D. The intervention group will receive personal health coaching by telephone and access to a smartphone and web application for 1 year. The control group will receive access to the application for 1 year and a one-time written diet and exercise recommendation. The primary outcomes are objectively measured physical activity and glycated haemoglobin. Secondary outcomes are self-reported physical activity, nutrition, cognitive mediators of changes in sport-related behaviour, blood values, medication and nutritional supplements, anthropometric data, quality of life, neuropathy and cost-effectiveness. All outcomes will be measured at baseline, at 27 weeks after inclusion and at 54 weeks after inclusion. The recruitment of participants and the measurements will be completed after 2 years. Linear mixed-effects models will be applied for each outcome variable to analyse the intervention effects. ETHICS AND DISSEMINATION: This study was approved by the Ethics Committee North-western and Central Switzerland in February 2021 (ref: 2020-02755). All participants will be required to provide written informed consent. The results will be published in international peer-reviewed journals. TRIAL REGISTRATION NUMBER: ISRCTN79457541.

Chemotherapy-induced peripheral neuropathy (CIPN) is an adverse effect of neurotoxic antineoplastic agents commonly used to treat cancer. Patients with CIPN experience debilitating signs and symptoms, such as combinations of tingling, numbness, pain, and cramping in the hands and feet that inhibit their daily function. Among the limited prevention and treatment options for CIPN, exercise has emerged as a promising new intervention that has been investigated in approximately two dozen clinical trials to date. As additional studies test and suggest the efficacy of exercise in treating CIPN, it is becoming more critical to develop mechanistic understanding of the effects of exercise in order to tailor it to best treat CIPN symptoms and identify who will benefit most. To address the current lack of clarity around the effect of exercise on CIPN, we reviewed the key potential mechanisms (e.g., neurophysiological and psychosocial factors), mediators (e.g., anti-inflammatory cytokines, self-efficacy, and social support), and moderators (e.g., age, sex, body mass index, physical fitness, exercise dose, exercise adherence, and timing of exercise) that may illuminate the relationship between exercise and CIPN improvement. Our review is based on the studies that tested the use of exercise for patients with CIPN, patients with other types of neuropathies, and healthy adults. The discussion presented herein may be used to (1) guide oncologists in predicting which symptoms are best targeted by specific exercise programs, (2) enable clinicians to tailor exercise prescriptions to patients based on specific characteristics, and (3) inform future research and biomarkers on the relationship between exercise and CIPN.
RESUMO
INTRODUCTION: Chemotherapy-induced peripheral neuropathy (CIPN) is a prevalent and clinically meaningful side effect of cancer treatment. CIPN is induced by neurotoxic agents, causing severe sensory and/or motor deficits, resulting in disability and poor recovery, reducing patients' quality of life and limiting medical therapy. To date, effective treatment options are lacking. Whole-body vibration (WBV) training can attenuate motor and sensory deficits. We are conducting a two-armed, multicentre, assessor-blinded, randomised controlled trial, to investigate the effects of WBV on relevant symptoms of CIPN and determine the training characteristics. METHODS AND ANALYSIS: In this ongoing study, 44 patients who have completed therapy in the past 3 months, with a neurologically confirmed CIPN are assessed before and after a 12-week intervention and follow-up. The intervention group receives WBV twice a week. Exercises are individually tailored according to the initially determined optimal neuromuscular response. The control group receives care as usual.Primary endpoint is the patient reported reduction of CIPN-related symptoms (Functional Assessment of Cancer Therapy/Gynaecology Oncology Group-Neurotoxicity). Secondary endpoints are compound muscle action potentials, distal motor latency, conduction velocity, F-waves from the tibial and peroneal nerve, antidromic sensory nerve conduction studies of the sural nerve, normalised electromyographic activity, peripheral deep sensitivity, proprioception, balance, pain, the feasibility of training settings, quality of life and the level of physical activity. AIM, ETHICS AND DISSEMINATION: The study was approved by both responsible ethics committees. (1) Our results may contribute to a better understanding of the effects of WBV on motor and sensory functions and (2) may provide information whether WBV at the most effective setting, is feasible for neuropathic patients. (3) Our results may also contribute to improve supportive care in oncology, thereby enhancing quality of life and enabling the optimal medical therapy.

BACKGROUND: Improvements in survival rates in pediatric oncology have resulted in a growing need to identify adverse effects and improve rehabilitation in this population. OBJECTIVE: This cross-sectional study aimed to investigate active ankle dorsiflexion (DF) range of motion (ROM), gait, walking efficiency, and motor performance in a mixed childhood cancer survivor population in comparison to healthy peers. METHODS: Active ankle DF-ROM (goniometer), gait (Microgate Optogait 2D Gait Analysis), walking efficiency (6-minute walk test), and motor performance (German Motor Test 6-18) were assessed in a mixed childhood cancer survivor population after cessation of medical treatment (n = 13) in comparison to healthy children matched for age and gender (n = 13). RESULTS: Active ankle DF-ROM, gait (stance, swing, and preswing phase), and walking efficiency were significantly impaired in survivors compared with control subjects. No significant difference between groups was found in motor performance. CONCLUSION: Despite sufficient total motor performance levels, specific limitations in physical functioning were identified in a mixed childhood cancer survivor sample. This highlights the importance of the present findings. IMPLICATION FOR PRACTICE: The results from this study highlight the potential significance of limited ankle DF function, inhibited gait, and reduced walking efficiency as adverse effects of various types of childhood cancer. It is hoped this enhanced recognition by pediatric cancer patients, parents, and exercise professionals will initiate specific supportive strategies and potentially prevent further limitations.

INTRODUCTION: Peripheral neuropathies (PNPs) encompass a large group of disorders of heterogeneous origin which can manifest themselves with sensory and/or motor deficits depending on the predominantly affected nerve fiber modality. It represents a highly prevalent disease group which can be associated with significant disability and poor recovery. Exercise has the potential to improve side effects of PNP. OBJECTIVE: Our objective in this systematic review was to analyze exercise interventions for neuropathic patients in order to evaluate the possible benefits of exercise. METHODS: Three independent reviewers used PubMed, MEDPILOT (MEDLINE), Cochrane, and relevant reference lists to obtain the data. Relevant studies were graded according to the Oxford Levels of Evidence. RESULTS: Eighteen studies (ten randomized controlled trials and eight controlled clinical trials) met all inclusion criteria. Three (diabetic) studies were ranked very high quality [1b (A)], nine high quality (four diabetes, one cancer, four others) [2b (B)], while six (four diabetes, two others) showed low quality (4/C). Current data suggests that exercise is a feasible, safe, and promising supportive measure for neuropathic patients. This is best documented for patients with diabetic peripheral neuropathy (DPN), suggesting that endurance training has the potential to prevent the onset of and reduce the progression of DPN. In general, balance exercises showed the highest effect on the motor as well as sensory symptoms in all types of PNP. CONCLUSION: Overall, balance training appears to be the most effective exercise intervention. Studies focusing exclusively on strength, or a combination of endurance and strength, appear to have a lower impact. For metabolically-induced neuropathies, endurance training also plays an important role. Further research with high methodological quality needs to be conducted in order to establish evidence-based clinical recommendations for neuropathic patients.

Most scientific studies regarding physical activity in cancer patients involve breast cancer patients. It is apparent that physical activity during medical treatment and aftercare is not only feasible and safe but also effective. Current studies clearly show that regular and specific endurance and/or resistance training can reduce a number of side effects caused by medical treatment. Among others, improvements in physical performance, body composition, and quality of life as well as a reduction in fatigue, have been observed. Since inactivity appears to exacerbate lymphedema, patients with lymphedema are also encouraged to exercise. Few studies have been carried out regarding physical exercise in metastatic patients. However, experts in the field also recommend regular physical activity for patients with advanced-stage breast cancer.
