OF have notably higher rates of falls and fall-related injuries than OM. Healthy OA compared to YA, and females compared to males of any adult age, have lower strengths and have development rates for at least some strengths that are lower. The results of the obstacle avoidance and balance recovery studies described suggest that OA are not notably more at risk than YA, nor are females notably more at risk than males, in avoidance and recovery tasks that are time-critical (TC), but do not have high strength (HS) requirements. The results suggest that for TC/HS avoidance and recovery tasks, OA compared to YA and females compared to males are substantially more at risk for injury. The source of these age and gender differences seems to lie primarily in differences in muscle strengths and speeds of muscle contraction once contraction is initiated, rather than in neural factors underlying the sensory processing or motor planning that leads to the initiation of muscle contraction. Perhaps these findings help to explain the high rates of falls and fall injuries among OA compared to YA, and among OF compared to OM.</p>","PeriodicalId":79355,"journal":{"name":"Muscle & nerve.

Local injections of BTX-A are particularly valuable in relieving focal spasticity around a joint or a series of joints. When integrated into an overall spasticity treatment plan with clearly outlined functional goals, BTX-A may offer significant benefits to the appropriately selected adult or pediatric patient. A range of clinical outcome measures are used to evaluate the patient prior to injection. Initial dosing guidelines are offered, though each patient may have a unique drug response profile and set of modifying factors that will be used as a basis for dose adjustments. Clinical benefit usually lasts for approximately 12 weeks, though in some patients the duration of effect may be longer. Assessment of the patient's clinical and functional status is performed at each follow-up appointment, and the contribution of BTX therapy to the goals of the patient and caregiver are evaluated. Other therapeutic options should be considered where appropriate, and the treatment plan revised when necessary.

The avid binding of botulinum toxin (BTX) to presynaptic neuron terminals and the diffusion characteristics of the medication allow relative ease of administration. For many clinical applications, efficacy may be improved, and adverse effects reduced, by more precise targeting of the muscles to be injected. Electromyographic guidance (EMG) is commonly used to confirm appropriate localization of the injection needle in specific muscles immediately before injection. Electrical stimulation (ES) may be more useful in patients who are unresponsive or sedated. Equipment options and technical aspects of EMG and ES are discussed, including some adjunctive imaging methods for injecting difficult-to-localize muscles.</p>","PeriodicalId":79355,"journal":{"name":"Muscle & nerve.
