Osteoporosis: Physiotherapy Management, Prevention & Safe Exercise Guide

Osteoporosis: Physiotherapy Management and Evidence-Based Exercise

Osteoporosis — characterized by reduced bone mineral density (BMD) and microarchitectural deterioration of bone tissue — affects over 50 million people in India, predominantly postmenopausal women and elderly men. The clinical consequence is increased fracture susceptibility, particularly at the spine, hip, and wrist.

The Physiotherapy Role in Osteoporosis

Physiotherapy does not replace medical management (calcium, vitamin D, bisphosphonates) but is an essential component of the multidisciplinary approach to osteoporosis for three specific goals:

1. Bone loading: Stimulating osteoblast activity through appropriate mechanical stress
2. Fall prevention: The primary driver of osteoporotic fractures is falls — not just bone fragility
3. Postural management: Addressing the kyphotic posture that develops from vertebral compression fractures

Bone Loading Principles: Which Exercise Builds Bone?

The Mechanostat Theory (Harold Frost) explains that bone responds to mechanical loading above a minimum effective strain threshold by activating bone remodeling. The key principle: load must exceed habitual daily activity levels to stimulate bone adaptation.

Weight-Bearing Impact (Highest Bone Stimulus)

• Heel drops: Stand tall, rise on tiptoes, drop heels sharply. The impact signal stimulates calcaneal and spinal bone response. 10 drops × 3 sets, daily.
• Walking on varied terrain: Uneven surfaces require greater dynamic loading through the hip and spine
• Step exercises (low step): Step-up/step-down on a 10 cm step

Progressive Resistance Training (Second Highest Stimulus)

Muscles pull on their bony attachment sites — high muscle force = high bone strain. Target the hip abductors (hip fracture prevention), spinal extensors (vertebral fracture prevention), and wrist extensors.

• Hip extension resistance: Donkey kicks, hip thrusts against resistance
• Spinal extensors: Prone back extension (no high-load spinal flexion)
• Grip and wrist strengthening: Wrist curls, putty squeezing

Fall Prevention Programme

Physiotherapy fall prevention is proven to reduce fall-related fractures by 30–40%:

• Balance training: Single-leg stance (holding support if needed), progress to less support
• Gait training: Correct foot drop pattern, improve step height
• Environmental assessment: Identify home hazards (loose rugs, poor lighting, no bathroom rails)
• Proprioception exercises: Standing on foam mat, tandem (heel-toe) walking, sideways stepping

Safe Posture Correction for Osteoporosis Kyphosis

Vertebral compression fractures cause progressive kyphosis (hunched posture), which shifts the body's centre of gravity forward — increasing fall risk and compressing anterior vertebral bodies further.

Safe postural exercises:

• Chin tucks (corrects forward head posture)
• Shoulder blade retractions
• Thoracic extension over foam roller (positioned mid-back — NOT at lumbar level)
• Hip flexor stretching (kneeling lunge)

Never do: Sit-ups, spinal flexion under load, or touching toes exercise in osteoporosis.
