Feeling Faint? Everyday Activities Can Make You Dizzy.

Dizziness can be caused by many things: side effects of medication, low blood pressure, low blood sugar, and anxiety. Dizziness following bending over to tie shoes, lying down in bed, looking in the blind spot, and walking down a grocery aisle are all frequent causes of dizziness related to a vestibular disorder. Vestibular dizziness symptoms may include everything from the room spinning to a feeling of off balance or unsteadiness.

There are three major systems in the body that help you maintain your balance. Vision helps to locate the horizon and objects in a person’s path. Sensory mechanics in the feet and legs help identify the type of ground underneath a person’s feet. The last system is the vestibular system which is located in the inner ear behind the ear drum. The vestibular system is what causes motion sickness, makes the stomach turn on a roller coaster, and what jolts a person awake when dreaming of falling.

The vestibular system has three main functions: stabilization of visual images (keeping eyes on a target), maintaining postural stability (especially with head movement), and providing spatial orientation. These three functions are controlled by coordination of the central vestibular system (brain and brain stem) and the peripheral vestibular system (shown to the left). There are two main parts of the peripheral vestibular system. The three fluid filled semicircular canals that detect angular head movement such as shaking your head to say “yes” and “no”. The vestibule contains the otolith organs which detect vertical and horizontal acceleration, like riding in a car and an elevator. If either of these systems are disrupted in any way it can cause dizziness. Two of the most common vestibular issues are benign paroxysmal positional vertigo (BPPV) and unilateral vestibular hypofunction (UVH).

BPPV is caused when otoconia (calcium carbonate crystals) from the vestibule fall into the semicircular canals. This causes movement of the fluid in the canals, which in turn moves the hair or ampulla, which triggers the sensation of movement. When someone with BPPV lies flat, bends forward, or looks up, this movement causes the crystals in the canal to move, moving the fluid, and then the hair, which triggers the sensation of spinning in the brain. This can be fixed by moving the crystals out of the canal by performing specifically sequenced positions which can treated by a medical professional familiar with vestibular rehabilitation in as little as 1-2 visits.

Unilateral vestibular hypofunction usually occurs following a viral illness, head trauma, or a vascular incident, such as a stroke or blockage, that decreases or eliminates the receptor input of the vestibular system to the brain. This causes less intense sensation of dizziness, more commonly characterized as feeling off balance. Common complaints of UVH are off balance or slight dizziness when turning a corner, picking something up from the floor, walking in the grocery store, or driving. Rehabilitation for UVH can take between 6-8 weeks with therapy to improve gaze stabilization (maintaining vision on a target), postural stability (maintaining standing balance), and decrease motion sensitivity.

Balance Issues? Your Appointment Explained.

Many times, doctors will send a patient to physical therapy if he/she has experienced a fall, been ill, or just felt unsteady while walking. There are several different components to increasing and maintaining balance and mobility.

When you arrive for your appointment, there will be paperwork to complete, most importantly a past medical history form, including a list of your medications. This information is needed to see if you have any conditions or take any medication that could contribute to your symptoms.

During the evaluation, the therapist will test the muscle strength in your legs and assess your balance. These tests are done in an effort to determine which system of balance needs to be addressed. There are three primary systems of balance: vestibular, visual, and proprioceptive. The vestibular system is located in your inner ear and is sensitive to head movements and can create dizziness if there is a dysfunction. The visual system plays a role in your balance by interpreting what you see and making adjustments to obstacles that are ahead, such as a curb. Proprioception is the feedback that you receive from your feet being in contact with a surface. This is important if you are walking on an unstable surface, such as grass or gravel. These three systems help maintain your balance, and your legs have to be strong enough to help hold you up!

The PT will analyze how you walk and determine if you need an assistive device, such as a cane or walker, for safety. Your balance may be tested by performing tasks such as balancing on one leg and standing with your eyes closed and by performing tasks that involve putting your feet close together or in front of each other. Some of these tests may seem silly, but they give the therapist information about your ability to perform daily activities safely.

Often, your therapist will want to see you once or twice a week to work on increasing strength and balance. One thing to remember with balance is that repetition helps the body re-learn the correct way to perform daily activities. More than likely, the PT will send you home with exercises to perform on your own. Performing these exercises will help maintain your mobility and strength between PT visits. Working on balance is a time-consuming process; you will need to be patient with yourself as your symptoms improve. Most importantly, therapists want patients to remain safe with their mobility and prevent future falls. By improving strength and balance, you will be on the right track to stay injury free!

Knee Pain Explained

Knee pain is something nearly every person experiences at one point or another, usually related to a particular injury or provocative activity, such as lots of kneeling for spring planting in the yard or playing the occasional game of basketball. How do you know the difference between a serious injury versus simple overuse? The causes of knee pain typically fall into one of three categories: traumatic, overuse, and degenerative.

Traumatic is self-explanatory; a fall, collision, twist, or awkward landing can create enough force to damage the structures inside the joint. When this type of damage occurs, the person may experience severe and immediate swelling, severe pain, a loss of ability to move the joint, and an inability to bear weight through the limb; a safe bet is when two of the three exist, the person should seek medical attention from a physician and/or physical therapist immediately. Attempting to “walk it off” is not recommended.

An overuse injury can be a little tougher to recognize. Starting a fitness program or a dramatic change in a person’s activity level (more or less) can provoke this type of pain. So can rapid increases in body weight, such as pregnancy. Adolescents who are going through growth spurts will often have pain in the knees because of changes in the way the muscles and joint function together. The pain may show up immediately or gradually, appearing more and more frequently until it is constant. Swelling may appear but is typically not severe and disappears overnight. Depending on the structure inside the knee that is taking the abuse, surgery may be needed, but many times this is treated quickly and effectively with a short course of rest, stretching and strengthening.

“Degenerative” describes the normal changes our joints experience with aging, specifically thinning of the articular cartilage and the loss of quality in the soft tissue of the joint. Knee pain from degenerative changes generally does not produce swelling and is provoked by remaining in one position for a great deal of time.

Besides pain, a problem within the knee (or any joint) will also cause the muscles around the joint to stop working effectively. Over time this will produce a loss of muscle size as well as a loss of control of the joint. The longer the joint remains untreated, the more severe the muscle atrophy and loss in function will become. Other joints may become painful as a result, particularly the areas above and below the injured joint or the opposite side. Medical treatment should begin before the body learns bad movement patterns.

Unless severe structural damage is present, a course of physical therapy will often be successful in getting rid of pain and restoring a person’s usual activity level. Any physician can refer to physical therapy and in many states no referral is required; in most cases, the therapist can make an accurate assessment of the problem and begin treatment immediately. If the problem is severe enough that a specialist should be involved, the therapist can facilitate the referral and also make recommendations for any diagnostic testing.

Regular Headache or TMD?

It’s been a long day that started with a pounding headache and a rough day at work. A great movie is on TV and the start to a perfect night of relaxation is complete with a warm bag of popcorn. As I settle in and the movie begins, I take the highly anticipated first bite and…OUCH! What was that? The pain is from my mouth but it’s not a normal toothache. The pain in my face and jaw travels up to my temple and ear. My headache has not only returned, but has intensified! I’m experiencing signs and symptoms of temporomandibular disorder (TMD). Can you relate? The National Institute of Dental and Craniofacial Research estimates over 10 million Americans are affected by TMD. This disorder impacts many within our own community and HPRC is here to help inform, educate and treat to restore a healthy and desired lifestyle.

Background: Anatomy and Function

Temporomandibular disorder involves the temporomandibular joint (TMJ) and/or the surrounding musculature. The TMJ is a hinge joint that connects the jaw to the skull, just in front of the ear on both sides of the head. Movement at the TMJ allows for up and down and side to side motions of the jaw for talking, chewing and yawning. The cervical spine and surrounding musculature influence the position and control of the joint.

What Are the Signs and Symptoms of TMD?

Common signs and symptoms are, but not limited to:

  • Pain in the jaw, face, temple region, neck, shoulder and/or ear at rest or during movement
  • Limited jaw motion opening, closing and/or side-to-side
  • A “stuck” or “locking” feeling in the jaw, “clicking” or “popping” when opening and closing the mouth that may or may not be painful
  • Headaches
  • Fatigue in the jaw, head and/or neck region

These symptoms may be temporary, recurring or chronic.

What Causes TMD?

The exact cause of TMD is not clear, but clinicians do believe signs and symptoms arise from problems in the surrounding muscles, the joint itself, stiffness in the cervical spine and poor ergonomics/posture. A rapid onset may occur after an injury, such as a blunt force to the face or whiplash. Other contributing factors include:

  • Grinding/clinching teeth at night
  • Osteoarthritis or rheumatoid arthritis in the TMJ
  • Dislocation of the disc in the TMJ
  • Work, home or emotional stress
  • Recent prolonged and/or high-level dental work
  • Recent cervical injury or surgery
  • Diet (i.e., nuts, ice, tough meats)
  • Overuse/habits (i.e., bubble gum, biting nails, chewing the end of a pen/pencil)

Treatment Options

The most effective treatment for TMD typically involves a collaborative team effort between the patient, a physician or dentist and a physical therapist. As the patient, the following steps may be help in easing symptoms:

  • A soft diet
  • Ice applied outside (ice packs, frozen vegetables) and inside (popsicles, pieces of ice) the jaw
  • Avoid extreme jaw motions that hurt and/or create popping
  • Reduce stress and learn relaxation techniques
  • Keep your teeth slightly apart and jaw relaxed during daily activities

A physician or dentist will evaluate you for TMD, as well as for other possible issues in the teeth, jaw, head and neck. X-rays or an MRI may be performed if found necessary to further examine hard and soft tissues. Medication may be prescribed to help with inflammation. Dentist and oral surgeons can prescribe a helpful tool to reduce the effects of grinding at night called a night guard or splint. These custom made appliances prevent the upper and lower teeth from coming together while sleeping, thus reducing the grinding forces that contribute to TMD.

Physical therapists play a key role in the collaborative effort to get you back to a healthy, desired lifestyle. A licensed PT at HPRC will evaluate and treat all factors contributing to your TMD to reduce symptoms today and to prevent recurrences in the future. Treatments include:

  • Manual techniques (i.e., stretching, mobilizations and manipulation of the TMJ and cervical spine)
  • Exercise instruction (stretching and strengthening of the musculature surrounding the TMJ and cervical spine)
  • Patient education (detailed activity modifications, postural instruction and relaxation techniques)
  • Modalities that help reduce pain and improve tissue health.

Carpal Tunnel Syndrome Explained

Do you wake up at night finding yourself having to shake out your hand because it falls asleep? Do your fingers go numb while you are typing at work? If you answer yes to either or both of these questions, you may have Carpal Tunnel Syndrome.

What is it?

Carpal Tunnel Syndrome is a condition in which the median nerve is compressed as it passes through an opening from the wrist to the hand called the carpal tunnel. It is formed by the carpal bones on the bottom of the wrist and a ligament structure on top (transverse carpal ligament) that runs across the wrist. The Median nerve, is just below this ligament, and provides sensory and motor functions to the thumb, index finger, middle finger and ½ of the ring finger.

Carpal Tunnel Syndrome is a repetitive use injury/Cumulative Trauma Disorder and can begin with numbness and tingling that comes and goes in above specific fingers; however, it can become constant, causing an increase in discomfort in the hand and even forearm. This can be caused from poor positioning while sleeping allowing wrist(s) to stay bent for long periods, using tools that vibrate for long periods of time, poor ergonomics while sitting and typing or even while standing at a work bench with repetitive use of hand(s). Other symptoms include weakness with gripping objects, dropping items with affected hand, swollen feeling in fingers, and/or awakening at night due to discomfort in thumb, index and middle fingers.

If you have these symptoms, It’s important for you to seek medical attention quickly as compression on the nerve will continue and can eventually lead to nerve damage.

How to treat it

Treatment will be based on your age, past medical history and the extent of the syndrome. To begin relieving compression on the nerve at the wrist and prevent wrist motion, wrist splints are beneficial to wear during the time the symptoms are more prevalent. Other treatments can include anti-inflammatory medication, phonophoresis/iontophoresis, median nerve glides, ASTYM (Augmented soft tissue mobilization), changing positions of work station (ergonomics), or surgery to relieve the compression of the nerve in the carpal tunnel.

If your symptoms are not improving with conservative treatment above, a nerve study (EMG) can be ordered to determine the location of the compression and its severity. As a result, this will allow the surgeon to determine if surgical intervention is warranted or to continue with conservative treatment to alleviate the symptoms.

If you have surgery, what to expect:

Surgery is a scary thought and there are risks involved; however, this surgery is performed using a scope and a small incision and recovery is time is minimized as long as you follow instructions via the doctor and your therapist. If you are non-compliant, the recovery can be long and make you question why you had surgery.

In general, the surgery for CTS is performed under local or regional anesthesia and is an outpatient procedure allowing you to go home the same day after surgery. For endoscopic approach, there is a small incision made at your wrist area, and the tissue that is pressing on the nerve will be cut to decrease the pressure.   After the surgery, a bulky dressing will be used to immobilize your wrist, but your fingers are free allowing you to move them immediately after surgery.

You will follow up in therapy 3-5 days after surgery. The bulky dressing will be removed, incision cleaned and your home exercise program will be initiated. A smaller dressing will be reapplied after therapy for ease of daily dressing changes at home. Approximately 10-12 days from surgery, stitches will be removed either by doctor or therapist and will continue to progress your movement and activities, as tolerated. The length of recovery can vary with each person especially if the nerve has been compressed for a long time, return of your sensation may take longer. Typically, four weeks from surgery, strengthening activities will begin under the supervision of a therapist to ensure you are progressing well without pain or discomfort. Weekly progression of resistance’s/weight limits are issued via your therapist and this methodical succession will return you to your prior level of function pre-Carpal Tunnel symptoms. Full recovery of the nerve is said to be approximately 18 months, but most people’s sensation returns well before that time frame.
