Exercises for Patients Who Were Receiving Chemotherapy

Study Overview
=================
Brief Summary
-----------------
To evaluate the effect of lower extremity strengthening and balance exercises on balance, quality of life and neuropathic pain of the cancer patients receiving neurotoxic chemotherapy.

Detailed Description
-----------------
Cancer-related mortality rates decreased considerably thanks to novel treatment methods and new agents over the last two decades. Although chemotherapy (CT) is an effective treatment type in reducing the size of the tumor and eliminating metastases, it may harm many different organs and systems due to short & long-term side effects. Peripheral neuropathy (PN) is regarded as a neurological and clinical side effect for cancer patients. PN may arise as a paraneoplastic symptom but more commonly occurs with neurotoxic CT agents. Short & long-term side effects that may damage sensory, motor, and autonomic neurons. This damage to the small-fiber sensory nerves causes a change in the sense of touch, pain, and warmth, while the damage to the large-fiber nerves causes a change in the sense of vibration and proprioception. Motor nerve damage affects voluntary movement, muscle tone, and coordination, and damage to the autonomic nervous system affects intestinal motility and blood pressure over smooth muscles. Despite the fact that studies on PN treatment have generally focused on pharmacological agents reducing pain or treating selected side effects, no agent that may be preventive for chemotherapy induced Peripheral Neuropathy (CIPN) due to neurotoxic chemotherapy has been recommended in the review of the American Society of Clinical Oncology. Side effects due to CT such as anorexia, nausea, vomiting, mucositis, diarrhea, anemia or PN may lead to impairment in the quality of life of the patient and may significantly reduce the level of physical activity. Neurotoxic and ototoxic effects may cause ataxia, paresthesia and dysesthesia, leading to gait, and balance disorders. CIPN has been associated with balance disorder, loss of function and reduced quality of life in the literature. It may result in loss of balance, difficulty in ambulation, increase in the frequency of collapse and accordingly increase in injuries. Despite the fact that medical treatments used in CIPN are often helpful in the treatment of neuropathic pain, no effect has been observed on muscle strength, gait, and balance. It is believed that muscle strength and balance exercises, such as aerobic exercises, can provide mitochondria with oxygen and glucose by increasing blood supply, thereby contributing to energy production and reducing symptoms. Current data suggest that exercise is applicable, safe, and beneficial for this group of patients. Balance exercises at an early stage may prevent or delay the onset of sensory and motor symptoms. Although exercise is accepted as a supportive treatment, which should be addressed more seriously for a patient population with PN, there is not enough information in the literature on timing, frequency, and mode of administration of the treatment program that will be carried out in this specific group of patients. The aim of this study is to investigate the effects of therapeutic exercise program including concurrently initiated strengthening, balance and aerobic exercises on the symptoms, balance status and quality of life of the group of patients who have a limited physical activity, a risk of developing PN following the treatment, and will have a long-term bed rest and compare with the group of patients not receiving any exercise program in the same treatment period.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Balance assessment | NeuroCom Balance Master® device (Natus Medical, San Carlos, California, USA) is a balance evaluation device measuring the position of the center of gravity, postural control along with static and dynamic stability. | 3 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Berg balance scale | Berg balance scale used in the evaluation of balance based on performance is a 14-item measure in which patient is required to perform different activities.14 different activities are scored between 0 (worst) and 4 (best) according to the patient's performance. The maximum score is 56. A total score close to 56 indicates that the balance of patient is good. | 3 months | 
| PainDETECT: questionnaire | The presence of neuropathic pain was evaluated with the painDETECT questionnaire. The maximum score is 35 and a high score indicates the severity of neuropathic pain. When the PD-Q score is more than 13, it is indicated the presence of neuropathic pain component. | 3 months | 
| The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire | It is a questionnaire developed by the European Organization for Research and Treatment of Cancer and used to assess the quality of life of cancer patients participating in clinical trials and includes a variety of components. Patients' higher points of functional scale and general health status scale and lower points of symptom scale scores indicate a high QoL. | 3 months |
